Speech Title--- Various Solar+ESS (Energy Storage System) Applications Controlled by

Smart-phone

Abstract--- Around the world, many governments have strived to increase the share of

renewable green energy in their power productions. The main interest has mainly been energy

security, increasing prices of carbon based energy sources and minimizing global warming.

Concerning the second, global shipping is a major contributor to GHG (global greenhouse gas)

emissions, bring responsible for approximately 3% of global CO2 emissions. Firstly, the first

application of solar-ship fabrication process is introduced.

In addition, we introduce the second application of stand-alone PV and Wind power hybrid

system. The solar and wind power hybrid generation and ESS will be very important in the

isolated island and distant place without electrical power supply. So we demonstrate a cold

storehouse for fresh fruits with a proto-type stand-alone PV system with ESS by using

smart-phone based on internet networking as the next generation solar power system with

various new applications.

Furthermore, we have been developed the eco-friendly power supply for various fast charging

and discharging applications based on our own developing new ESS (super-capacitor/Li polymer

battery/Chemical Battery). And we introduce the future of ESS applications such as new farming

system, micro dust removing eco-friendly bill-board system and so on.

Title--- Transformer-less Online Uninterruptible power supply (UPS) system

Abstract--- Uninterruptible Power Supplies (UPS) are widely used to provide reliable and high

quality power to critical loads such as such as airlines computers, datacenters, communication

systems, and medical support systems in hospitals in all grid conditions. Online UPS system is

considered to be the most preferable UPS due to its highest level of power quality and proven

reliability against all types of line disturbances and power outages. This paper presents a new

topology of the non-isolated online uninterruptible power supply system. The proposed system

consists of bridgeless boost rectifier, battery charger/discharger, and an inverter. The rectifier

performs power factor correction and provides regulated DC-link voltage. The rectifier operates

with a minimum semiconductor device, reducing the conduction losses of the circuit significantly.

A new battery charger/discharger has been implemented, which ensures the bidirectional power

flow between the DC-link and the battery bank, reducing the battery bank voltage to only 24V,

and regulates the DC-link voltage during battery mode. The proposed controller shows significant

improvement in terms of reducing the total harmonics distortion to 0.5% for linear load and 1.25%

for non-linear load, strong robustness, and fast response time of only 0.3ms. Operation principle

and experimental results of 1kVA prototype have been presented to verify the validity of the

proposed UPS. The efficiency of the proposed system is 94% during battery mode and 92% during

the normal mode of operation.

Title--- Energy Transition toward Green and Sustainable KOREA

Abstract--- For sustainable economic development and substantial mitigation of climate change,

low carbon green growth is one of primary national agenda in Korea. The present Korean

government elected in May 2017 had announced the new national strategic plan of renewable

energy (RE2030) and its RE deployment action. The new RE target goal is to supply 20% of the

total electricity with RE by 2030, compared to the previous goal of 13.5% by 2035 set up in 2014.

As of end of 2016, the RE electricity was 39.2Twh, consisting of 7.0%. Furthermore, the 58% of RE

electricity was produced from the waste incineration (not included in IEA RE

classification).According to the RE2030 plan, the new RE facilities will be consisted with PV, Wind

energy, FC and other clean energy. The fiscal budget for renewable energy deployment in 2016

amounted to 800 million USD. For successfully achieving the RE 2030, Approximate 9.2 billion

U$ will be invested for new facilities, 5.1 billion U$ from public sector and 4.1 billion U$ from

private sector. The new 5GW/year RE facilities will be constructed from ’18 to 22. Another 23.8

GW RE will be added by ’30. The new major facilities of RE2030 include Large scale PV, Floating

PV, Onshore/Offshore Wind, FC, Marine energy, Zero energy house. There are a variety of

renewable energy deployment programs, such as Renewable Portfolio Standards (RPS),

Renewable Fuel Standard (RFS), Building Subsidy Program, Home Subsidy Program, Feed-In-Tariff

(FIT), Solar Rental Program and etc.. It should be mentioned that so far, Korea has been very

heavily dependent on the nuclear power, more than 40% of its total electricity. With increase of

RE share, the government endeavors to reduce the nuclear share, ultimately free of nuclear

power plant. The ultimate goal of Korean Energy Policy is greener, safer and more sustainable

society. The present and prospect of renewable energy in Korea will be presented with other

climate change mitigation policy and measures.

Energy use prediction with information theory and machine learning technique

YW Tong, WY Yang, and DL Zhan

Nanchang University, China

Abstract. Appliances energy consumption plays an increasingly important role in

the overall building electric energy consumption and its temporal trending.

However, predicting appliances energy consumption is complicated by lack of

causal understanding of the appliances energy use as well as too many potential

predictors that might be relevant to the appliances energy use. In this study, we

apply information theory and advance machine learning neural network technique

to first rank the importance of potential drivers that dominate appliances energy

consumption and secondly model the temporal evolution of appliances energy

consumption with a restricted set of environmental predictors. Our results showed

that temperature and humidity were the two most important environmental

drivers in the house appliances energy consumption modeling. Furthermore, using

those environmental drivers, the machine learning model was able to accurately

capture the temporal dynamics of appliances energy consumption.

The Impact of Economic Growth, Energy Consumption And Demographic

Dynamics On Carbon Emissions: A Cross Country Analysis In 133 Nations

Pham Thi uy TranThg, Nguyen Thi Xuan Hanh, Bui Pham Phuong Thanh

Thu Dau Mot University, Viet Nam

Abstract. The growth of economic has been a determinant factor increasing the

volume of greenhouse gases, particularly CO2 emissions. To provide appropriate

measures to control CO2 emission, it is necessary to address how such factors as

population and economic growth impact the emission of carbon dioxide in any

developing country. However, the answer to what are the key factors or whether

these factors have jointly impacted on CO2 emissions has been debated so far. This

paper chooses five main factors, including economic growth, population growth,

energy consumption, age structure and urbanization as independent variables for

multiple regression model to analyse the relationship between these variables to

CO2 emission variable in 133 countries. The result shows that all these factors

jointly impacted on CO2 emissions energy use and demographic factors should be

controlled due to the highest contribution to the level of CO2. The research

findings are expected to shed a light on those countries policy making in coping

with climate change.

wastage due to improper energy audit on the energy performance. The wastage of

energy occured due to the lack of awareness between students and staff, and

limited particular guidelines for the management to improve the situation. Effort

need to be made in retrofitting the buildings, to make it more energy self –

sufficient, that leads to energy saving and improve the building’s energy

performance. The aim of this research is to improve the energy performance in an

existing university building with the adaptation of Building Information Modelling

(BIM). This paper will review on the energy performance process based on actual

condition of an existing university building with the adoption of BIM based on

previous researchers. It will identified the potential strength and weakness of

applying BIM through energy performance process. The outcome of this paper will

be used to integrate BIM in retrofitting the existing university building in order to

improve energy performance. Furtheremore, it will help the facilities management

in university to gain more accurate energy usage during the maintenance work.

Hybrid-approach for sinkhole occurrence risk mitigation in urban areas

A A Malinowska, A Guzy, R Hejmanowski,P. Ulmaniec

AGH University of Science and Technology, Poland

Abstract. Presented research focused on the development of a novel methodology

for sinkhole risk assessment above shallow caverns in a salt mine. The research

was carried out for the Wieliczka Salt Mine, which is registered on the UNESCO list

and visited by near around 2 million tourists every year. The main assumption of

the investigation was to estimate root cause of sinkhole occurrence on the surface.

Based on the arch pressure theory the vertical stress in the roof of salt caverns

was established. Constructed three-dimensional model of underground mine

allowed to determine the stresses between the caverns. Furthermore, the caverns

which were hazarded by roof collapse were indicated. Hybrid solution was

supported by multicriteria risk analysis based on Analytic Hierarchy Process carried

out in Geographical Information System. Spatial analysis led to the identification of

caverns potentially influenced by other risk factors. Developed final risk maps

were based on four the most significant risk factors leading to sinkhole

occurrence. Vulnerability maps developed with support of Analytic Hierarchy

Process indicated areas where habitants and infrastructure are exposed to

sinkhole occurrence. Merging risk maps with vulnerability maps led to final hazard

map, where urban areas susceptible to sinkhole occurrence were shown. In

conclusion, the research carried out proved that combined spatial analysis with

theoretical solution may pave the way for reliable sinkhole risk assessment above

shallow caverns.

Synthesis and Evaluation of a Modified Polyepoxysuccinic Acid as a Kind of

Inhibitor for Industrial Recycling Water

Yiyi Chen, Yuming Zhou and Qingzhao Yao

Southeast University, China

Session

18

Abstract. Modified polyepoxysuccinic acid (PESA) scale inhibitor, epoxysuccinic

acid-oxalic acid-allypolyethoxy carboxylate (ESA-APEM), was prepared through

free-radical polymerization on PESA with oxalic acid-allypolyethoxy carboxylate,

and then applied for the inhibition of calcium carbonate scales from cooling water.

The structure of ESA-APEM was characterized by Fourier transform Infrared (FTIR),

and the inhibition performance toward CaCO3 was studied by the method of static

scale inhibition test with different dosages. The polymer ESA-APEM exhibited

more excellent scale inhibition property against calcium scales than the PESA. The

maximum CaCO3 efficiency of ESA-APEM was as high as 94.5% in the concentration

of 12 mg/L. The modified calcium scales in the presence of ESA-APEM were

analyzed by scanning electron microcopy (SEM).

Universities

Yi-Xin Cai, Sheng-Jung Ou, Hsuan-Hung Chen, Chien-Chen Chiu

Chaoyang University of Technology, Taiwan

Abstract. Sustainable environment development has become a global and

popular issue. In Taiwan, regardless of public authorities or private organizations,

departments often promote green buildings, green campus and other practices

according based upon different sustainable plans. In 2007, the Ministry of

Education promoted the green universities and formally launched the Green

University Development program [1]. Subsequently, in 2009, 13 schools jointly

signed "The Tallories Declaration" to promote the sustainable work of the Green

University. Up to 2018, eight universities have entered the ranks of the world's

largest green universities [2]. For finding better sustainable development

strategies to improve the Green university evaluation and environmental

benefits, this study analyzes the current situation of the Green University in

Taiwan and presents a trend analysis of the development of Green University

assessment indicators in Chaoyang University of Technology (CYUT) over the years.

Finally, through the analysis, the study proposes the concrete strategies for

achieving green university's requirement, and proposes the key strategies of

further achieving sustainable energy saving of green campus for Chaoyang

University of Technology.

Investigation of Pd-Ir based alloy catalyst with rare earth elements: comparison of

activities towards oxygen reduction reaction

Do-Hyung Kim, Eunae Lee, Byung-June Lee,Jong-Sung Yu and Chanho Pak

Gwangju Institute of Science and Technology, Korea

Abstract. To enhance catalyst activity of the palladium (Pd) towards oxygen

reduction reaction (ORR), iridium (Ir) and yttrium (Y) and rare-earth elements such

as lanthanum (La), and scandium (Sc) were alloyed by polyol method. In the case

of Y, it is hard to reduce Y ion completely by polyol method due to the low

Session

19

reduction potential of Y. However, the binding energy of the Pd from the XPS

analysis is shifted to a lower value, which indicates the delectron of Pd is filled by

the electron from the Y. Among the catalysts, the Pd4IrY0.1/C showed the best

activity towards ORR, which indicates the metallic Y is effective for improving the

catalytic activity. Other rare earth elements like Sc and La also showed a similar

tendency to Y element. Thus, for further enhancing ORR activity, the novel method

for complete reduction of rare earth atoms is demanded.

Renewable, Local Electricity Generation from Palm Oil Mill Residues: A Case Study

from Peninsular Malaysia

Ida Fahani Jaye, Jhuma Sadhukhan and Richard James Murphy

University of Surrey, UK

Abstract. The potential for generating renewable electricity from palm oil mill

residues (POMR) has received policy support from the Malaysian government for

almost two decades. However, uptake of the technology is still relatively low and

has not yet created a strong investment trend. A significant issue that has

dominated the discussion for many years is how to translate the renewable

electricity generation potential from POMR into actual implementation. Although

there are many appealing reasons and considerable opportunities to venture into

this POMR-based electricity generation business, clearly there are also substantial

barriers since it has yet to achieve commercial maturity and remains at the

pioneering stage of the industrial life cycle.

This thesis analyses the feasibility of generating renewable electricity from POMR

by exploring the technical, economic and environmental perspectives of this

electricity generation. The exploration seeks to understand the opportunities and

barriers to a more sustained investment in the use of POMR for a Sustainable

Electricity System (POMR-SES). A combination of mathematical analysis and

simulation using Aspen Plus software was employed to assess the technical and

economic feasibility of the system. The techno-economic analysis was combined

with life cycle assessment (LCA) to incorporate the environmental impact

perspective into the POMR-SES evaluation. The results show that POMR-SES with

an installed capacity of 4 MW or greater is technically feasible, economically viable

and environmentally favourable. The electricity generated from a 4 MW POMR-SES

is sufficient to meet a mill’s operational electricity and heat demand, any parasitic

load of the POMR-SES and provide surplus electricity to the national grid. At this

scale, a project can be expected to provide at least a 20% return on investment

(ROI), a seven years payback period and a 1.2 kg/kWhelec. carbon dioxide

avoidance compared with current Malaysian electricity grid average.

This research provides evidence and practical recommendations for various actors

such as prospective investors, analysts, stakeholders, mill owners and policymakers

and government agencies such as the Sustainable Energy Development Authority

Malaysia (SEDA) on the potential for efficient and sustainable utilization of POMR. It

is hoped that this study will also make a modest positive contribution towards

achieving the national renewable energy target for additional renewable power

supplies and contribute to improved global sustainability.

National Taiwan Ocean University, Taiwan

Session

Abstract. The present study was conducted in two parts. The first part incorporated

a two-step synthesis assisted by an ultrasound technique to prepare Al2O3

nanofluids for the thermal-electrochemistry experiment. In addition, a

sedimentation experiment verified suspendibility, stability, and thermal

conductivity to determine the best mixing method. 0.5-2.5 weight-percent

concentration (wt.%) nanofluids were added into a battery cell with copper and

aluminum electrodes for an oxidation reduction reaction to test the generating

capacity between 20 and 40℃. The second part derived two empirical formulas of

thermal conductivity and generating capacity for alumina nanofluids using the

innovation dimensional analysis to examine the functional relationships between

experimental parameters. The results of the property verification and

experimentation in the first part indicated that Al2O3 nanofluid and emulsifying

agent mixture at a concentration of 1 wt.% had the best thermal conductivity, and

that this decreases as the concentration increases. At 40℃, 2.5 wt.% nanofluid also

had the highest electric charge density; however, the rate of increase was less than

7% higher than that for 2 wt.% nanofluid. The results of the second part indicated

that for 0.5-2.5 wt.% Al2O3 nanofluid between 20-40℃, inserting the temperature

and concentration parameters can estimate the thermal conductivity and the

electric charge density using the empirical formulas in the present study.

Estimating the Impact of the MRT Elevated Railway System on Carbon Reduction in

Taichung, Taiwan

Kuo-Wei Hsu, Hsiao-Sung Chan, Jen-Chih Chao, and Pei-Chen Wu


Abstract. Amid rapid global economic development and the threat of global

warming, green transportation and related issues have risen to prominence in

various countries. In Taiwan in_2009, Taichung was selected as a low-carbon

demonstration city, in which energy conservation and carbon reduction would be

actively promoted, with the wider aim of developing a green economy and lifestyle.

This study explores the carbon-reduction benefits of the MRT elevated railway in

the Taichung Metropolitan Area. The railway’s construction has been associated

with intensive redevelopment of existing stations, but this process has been

unbalanced due to railway physical. Five new stations will also be added, and

belt-like spaces at ground level made available for housing and other

non-railway-related purposes. Utilizing literature collection and the Analytical

Hierarchy Process (AHP) research method to explore the factors affecting the

efficiency of the MRT, this study reveals that the AHP weights of the main criteria

for the escalation of MRT development in Taichung are 0.5833 for green

transportation and 0.4167 for green environment; while in the overall ranking of

the sub-criteria, the top three evaluation factors are mass transportation (0.31337),

greenery planting (0.21832), and green building (0.19444).

Abstract. Wind speed is caused by the movement of the Railway saves kinetic

energy which can be used as an alternative wind energy. Based on the data from

the Indonesian Central Bureau of Statistics, the average wind speed on the island of

Java is 7.5 m / s. The wind speed can produce a power capacity of electrical energy

that has been converted, which is equal to 50 watt. With the design of a wind

turbine that has a height of 50 cm and a cross-sectional area of 0.047 m2. The

capacity of electric power is very potential in terms of the use of renewable wind

energy. Placement of wind turbines around the railroad track area, the other

objective is as a security tool or called a guardrail which is an effort to prevent and

reduce the level of accidents around the area.

Abstract. Since there has been growing concern about the damage that

atmospheric leakage and dispersion accidents may have done to human beings,

researchers are dedicated to study effective and feasible source estimation

methods in chemical plant clusters. In this paper, the safety monitoring of chemical

production process is conducted via an unmanned aerial vehicle (UAV) monitoring

system. Based on the observed data from this system, a source estimation method

incorporating Bayesian inference and Particle Swarm Optimization (PSO) is

proposed. Furthermore, the method is extended to discuss the source tracing

algorithm using game theory in the UAV system. Finally, a practical case study is

carried out to verify the feasibility and credibility of the proposed method. Results

show that the method and system are helpful for safety monitoring and risk

assessment in a chemical plant cluster.

Abstract. In recent years, a smart house combining renewable energy systems has

been rapidly developed. In our laboratory, we develop an algorithm to decide the

operation plan of the storage battery introduced in the smart house. In the

previous research, we simulated the operation of storage batteries for

representative day aimed at leveling power load. From the simulation results on

Session

the representative day of the January, April and July, the power load is leveled in

each month. Also, the average value of the power demand after power load

leveling in one day is defined as the power load leveling line. However, because the

power load leveling line differs from each day, it is necessary to investigate the

change of the power load leveling line in several days. Also, in predicting power

demand for one house, because how to use electricity is left to customers,

predicting power demand is difficult. When planning the operation of storage

batteries for several days with multiple houses, because the demand power is

smoothed by the smoothing effect, it is expected that the power load leveling line

will almost unchanged on each days. However, it has not been investigated how

much the power load leveling line will change. Therefore, in this paper, we simulate

the operation of storage batteries in one house or 20 houses for 3 days and

investigate the change of the power load leveling line. Furthermore, this paper

shows how the fluctuation width of the power load leveling line by 20 houses can

be suppressed more than in one house. The smart house system consists of a

storage battery, bidirectional inverter, photovoltaic power generation, and electric

demand load, which connected to the commercial power grid. Operation of storage

batteries is planned by Genetic Algorithm (GA) analysis method. The simulation

period is from 14th to 16th in Kitami City, Hokkaido, in January (winter), April

(middle term), July (summer). The data using for simulation is solar radiation data

obtained from NEDO, and power demand data obtained from Hokkaido Electric

Power. The simulation result shows that the fluctuation width of the power load

leveling line for 3 days in 20 houses is smaller than one house, and further the

fluctuation width of January, April and July in 20 houses for 3 days can be reduced

by 6.6%, 0.2% and 27.3% than one house. We shows that power management is

better to control at multiple houses.

a solar power tower

Jingze Yang, Zhen Yang and Yuanyuan Duan

Tsinghua University, China

Abstract. Concentrated solar power (CSP) with thermal energy storage is a

dispatchable backup option and can provide a reliable output for the demand. The

supercritical CO2 (s-CO2) Brayton cycle integrated with a solar power tower (SPT)

leads to higher maximum temperature and thus higher efficiency of the

thermodynamic cycle, and is an alternative in drought region under dry cooling

conditions. The molten salt is selected as the heat transfer fluid (HTF) and thermal

storage medium. Due to the variations of solar irradiance, ambient temperature

and electricity demand, the s-CO2 Brayton cycle integrated with a SPT mostly

operates under off-design conditions. However, the off-design performance

analysis of such system has been rarely discussed. In this study, the off-design

performance of a 50MWe s-CO2 Brayton cycle integrated with a SPT was analysed.

Session

The system operated with sliding pressure control strategies and the mass flow rate

of HTF in evaporator was adjusted to meet the power output demand. The design

operation parameters and heat exchangers geometric parameters were first

determined. Then the solar field aperture area and thermal storage volumes were

obtained under typical conditions of the power demand and solar irradiation. The

system efficiency under off-design conditions over a day could be obtained.

Start-Up and Dynamic Processes Simulation of SOFC-MGT Hybrid Power System

Deng Kangjie and Yang Chen

Chongqing University, China

Abstract. For the start-up process of a hybrid system consisting of a Micro Gas

Turbine (MGT) and a Solid Oxide Fuel Cell (SOFC), the surge of the MGT is largely

destructive. The MGT, which has a small thermal inertia, can start quickly.

However, due to the large thermal inertia of SOFC, starting up SOFC quickly is

easily malfunction. Therefore, fast and safe start-up process investigation of the

coupling hybrid system is of great challenging and significance. This paper

developed a dynamic model of the SOFC-MGT hybrid power systems and studied

the rapid start-up process in the case of avoiding gas turbine surge and protecting

SOFC by adding other afterburning, auxiliary systems, and bypass valves. The

result shows that the bypass from compressor exit to atmosphere can effectively

avoid system unstable and the strategy of starting the MGT and SOFC respectively

is reasonable. The start-up process simulation provides a reference to the actual

SOFC-MGT hybrid power systems.

Performance analysis of a two-stage gravitational water vortex turbine

Taqi Ahmad Cheema†, Rizwan Ullah and Abdul Samad Saleem

GIK Institute of Engineering Sciences and Technology, Pakistan

Abstract. In the present study the performance of two-stage gravitational water

vortex turbine (GWVT) assembled in a conical basin with Savonius blade profile

configuration has been investigated at different flow rate and vortex elevation.

Two-stage GWVT with conical basin, not only increases the performance

parameters with increase in flow parameters, but the lower stages also feed

additional impact to the stage located above it because of forced vortex

generation in the vicinity of top stage. Moreover, maximum hydraulic head drop

near the orifice is the main contributor in the power generation of the bottom

stage, by giving rise to strong tangential velocity. A stage starts power production

as soon as the parabolic surface of the vortex approaches the corners of the

blades even in the absence of a significant water-blade interaction. The developed

analytical model qualitatively predicts the performance of the turbine minutely

leading the experimental results quantitatively.

temperature limit

Jian Li, Jingze Yang, Zhong Ge, Yuanyuan Duan and Zhen Yang


Abstract. Organic Rankine cycle (ORC) is a widely used technology to generate

power from renewable energy and waste heat. Dual-pressure evaporation cycle

holds immense potential to be used in ORC systems because it can remarkably

increase the heat-work conversion efficiency and improve the adaptability of ORC

to heat sources with various characteristics. This study compared the

thermodynamic performance of single-pressure and dual-pressure evaporation

ORCs for heat sources with outlet temperature limit, based on five organic fluids.

Effects of the heat source outlet temperature limit on the characteristics of

dual-pressure evaporation ORC system were also discussed. Results show that the

dual-pressure evaporation cycle can substantially increase the net power output

by increasing system efficiency, and is beneficial to reduce the charge volume of

organic fluid in the system, compared to the single-pressure evaporation cycle.

The increments in net power output of dual-pressure evaporation cycle over the

single-pressure evaporation cycle can be 4.9%, 8.3%, 10.8%, 12.8%, and 14.0% at

most for R227ea, R1234ze(E), R600a, R245fa, and R601a, respectively. While,

compared to heat sources without outlet temperature limit, the increment in net

power output of dual-pressure evaporation cycle is remarkably lower for heat

sources with outlet temperature limit.

Kuwait Institute for Scientific Research, Kuwait

Abstract. With an over growing problem of plastic waste accumulation, Kuwait

faces a serious threat to its natural resources. Latest estimates show that plastic

solid waste (PSW) is generated at an alarming rate of over 200 ktpa, making up

over 16% of the total municipal waste load. In this paper, the standards test

method of ASTM D 5988-12 for determining the degree and rate of

biodegradation of plastics in contact with soil was applied to three commercial

plastic products sourced locally. The plastic samples are claimed to be of

biodegradable nature by the manufacturer and the converter. The test method

was applied in situ using analytical desiccators and have proven to be a good

indicator to biodegradable measurements. In addition to technical control and

reference tests, the test method was also applied on the natural soil secured

from the field simulating the largest operating landfill site. The test has proven to

be reliable and has produced repeatable results. The biodegradation extent was

noted to be very rapid and can be described by comparison to other works as

accelerated. This was attributed to both what is described by this work as

external and internal factors of the polymer-soil matrix. The former can be noted

as environment and soil characteristics, pH level and presence of contaminants in

the biota. On the other hand, the latter can be described as type of soil (mixture)

ratio, polymer surface area and carbon dioxide (CO2) evolution kinetics which

were noted to be of a first order with respect to biodegradation time and

Abstract. Biochar is a carbonized solid material obtained through pyrolysis of

biomass (weeds, crop residues and other wastes). Biochar application in soil is

considered as means to sequester carbon and improve soil functions for

improving plant growth. The effect of biochar also depends on soil texture, time

of application and its mineralogical properties. A pot experiment was conducted

on biochar to evaluate effects on plant growth and post-harvest soil properties.

The present investigation was performed in acidic soil with very low organic

carbon and nutrient content. Three different viz. 2, 5 and 10% (w/w) rates of

biochar treatments was applied. The physicochemical characterization of biochar

was conducted using FTIR, SEM, SEM-EDX, proximate, ultimate and BET

analytical technique. Biochar application to the soil significantly increased height,

leaf number, collar diameter and leaf area of Oroxylum indicum. The plant

biomass grown at 10% biochar treatment was highest. Also the post-harvest soil

analysis shows that there has been a significant increase in soil organic carbon,

The Discussion on the relationship among indoor air quality, environmental

cognition and user’s behaviour

Xue-Min Xu and Sheng-Jung Ou


Shanghai Art and Design Academy, China

Abstract. Indoor Air quality inspection is an important environmental assessment

work before the newly decorated space is open to use. Air quality is a dynamic

factor affecting environmental health. It mainly evaluates the concentration of

harmful volatile gases such as formaldehyde (HCHO), volatile organic compounds

(VOCs) in the air, and the concentration of dust and other indicators. The release

of these harmful substances changes with the physical factors of the

environment that many studies focus on and explore the complex correlations

among them. But as a user in the environment, does the behaviour also affect

the air quality? In view of this, the study takes the Master's Research Office of

Chaoyang University of Technology in Taichung as an example and tries to

explore if the release of formaldehyde (HCHO) and volatile organic compounds

(VOCs) has any correlation with the cognitive and behavioural activities of people

in their environment. In addition to the measurement of the concentration of

formaldehyde (HCHO) and volatile organic compounds (VOCs) under the

established conditions in the process of the study, the questionnaire survey was

used to know the subject's cognition of the environment, such as the freshness

of the air, the ventilation of the space, etc. Through statistical analyses, However,

the results showed that there were no significant differences in environmental

cognition between the before and after measurements. The results also revealed

that there were no change of having bad psychological feeling and only a slight

change of having bad physiological feeling between the before and after

measurements. The study concludes that the assessment of indoor air quality

needs to be based on consideration of people's perceptions of the environment

and behavioural activities, not just the level of harmful substances in the air.

Through the cognition of the environment and the effective intervention in the

behaviour process, the harm caused by the air quality problem to the health of

the human being can be alleviated to some extent.

Abstract. Using Global Land30 standard product as data source, combined with

CA-Markov model to quantitatively study the land use evolution of Pyongyang

municipality in North Korea from 2000 to 2010 and simulate the land use

situation of the region in 2020, the research found: (1) From 2000 to 2010, the

area of forest land and bare land in Pyongyang was greatly reduced, and the

cultivated land, grassland, water body and artificial surface increased to varying

degrees, and the expansion of cultivated land area was the most significant. (2)

In the first decade of 21st Century, the comprehensive utilization of land use in

Pyongyang increased, the information entropy declined weakly, and the land use

system remained in a stable and orderly state. (3) In 2020, cultivated land in

Pyongyang is still the main type of land use, but the area will be significantly

reduced, and the artificial surface will continue to expand, becoming the main

land area for area transfer. (4) The land use change in Pyongyang is mainly driven

by the three aspects of consumer demand, economic benefits and government

decision-making. With the development of society, the influence of economic

interests will become more and more prominent.

Assessing the impacts and spatial pattern of vegetation and land surface

temperature by a strong typhoon in Kinmen Island

Abstract. Under the global environment and climate change, the frequency and

intensity of natural disaster events have increased. Island has been hit harder by

strong wind strikes due to the island closure and low-lying landscapes. Therefore,

the environment change of strong wind strikes on island urban and rural areas is

the important issue.

In this study, we take the Kinmen Island as the study area to explore the spatial

pattern of damaged vegetation and land surface temperature and determine the

factors of influence of Typhoon Meranti in September 2016. The influencing

factors consist distance of Meranti’s path, elevation, slope, aspect, and land use

types, exploring the relation between normalized difference vegetation index

(NDVI) and land surface temperature (LST). Data were primarily collected from

the Landsat Thematic Mapper Satellite Image July 27, 2016 and Aug 15, 2017, to

calculate the NDVI and LST; the Land Use Investigation of Taiwan, 2014 and the

digital elevation model (DEM). This study applied analysis tools, including

analysis of correlation coefficient, and analysis of variance (ANOVA).

The results showed that 2085.44 hectares vegetation areas were effected by

Typhoon Meranti. For the aspect, the number of damaged vegetation pixels

decreased with flat land, mean NDVI of subtracting 2016 from 2017 was -0.0834.

Flat land was significant about strong wind impact. For the land use, mean NDVI

Session

of subtracting 2016 from 2017 of dryland farming and artificial broad-leaved

forest were -0.095, -0.063. Dryland farming and artificial broad-leaved forest

were significant about strong wind impact. The correlation of the NDVI and LST

both of subtracting 2016 from 2017 -0.458, but the pixels in recreational use on

the flat land was -0.901.

As the results, we could find that the impacts of vegetation by strong wind in

island, the flat areas are more serious than slope areas. As the result of

vegetation decreased and the LST increased, the quality of natural environment

and life will be effected.

Abstract. Lakes, the inland bodies of standing fresh water, have generally

occupied a small percentage of the earth total water. They are, however, of much

importance to humans for many commercial purposes which includes fishing,

irrigation and industrial water supplies aside from their intrinsic ecological and

environmental values as they help regulate temperature. This study served as

the first formal documentation of the baseline information on the water quality

of Lake Dasay in San Miguel, Zamboanga del Sur, Philippines. The study was

conducted in situ which aimed to evaluate the quality of the lake waters through

a descriptive-comparative approach having six (6) sampling periods for a year.

Composite sampling method was considered in the three randomly selected

stations. The collected data were statistically analyzed to determine the

significant differences on water qualities between sampling stations and periods.

Results of the study shows that DO ranges from 5.20 – 7.30 mg/L which is found

to be ideal to support aquatic life. Water temperature recorded 30 - 31◦C; 5.87 –

7.45 pH; 0.24 – 0.60 μS/cm conductivity; 9.49 – 14.42 mg/L TDS; 0.70 – 1.9 mg/L

BOD and 2.40 – 3.66 mg/L Chlorophyll a. No significant differences on water

quality observed between stations and sampling periods. Findings show that the

13,327 tons/day in 2017. About 79.5% was disposed by landfill and 20.5% was

recycled. The compositions of MSW were biodegradable (49.58%), combustible

(36.32%) and non-combustible (14.10%) wastes. Moisture content was

59.5±8.6% (as received), volatile matter, fixed carbon and ash were 72.4±3.2%,

8.2±0.5% and 19.4±0.5% (as dry basis), respectively. Heating value was

20.03±0.52 MJ/kg. These results indicated that MSW from Bangkok municipality

is potential to produce the refuse-derived fuel. To reduce the environmental

impacts as well as energy recovery, the MSW might be alternative sources of

renewable energy in the future.

Universitas Islam Indonesia, Kampus Terpadu UII, Indonesia

Abstract. Biodiesel is one of the potential renewable energy resource, mainly in

Asia. Many efforts are attempted for the low cost, efficient and economist

process in biodiesel conversion. Instead of intensification, the exploration of low

cost and environmental friendly catalyst is also focused. In this paper, the

preparation of low cost catalyst was derived from biogenic silica, which is

obtained from Bamboo leaves ash. Heterogeneous acid catalyst was designed by

attaching Fe2O3 into the silica as active site of the catalyst. Description on

preparation, characterization and activity test of the catalyst were performed.

Physicochemical character of the material was studied by XRD, FTIR, SEM-EDX

and surface acidity measurements, while for the catalytic activity test, biodiesel

A Study on Application of Ecological Engineering Methods to a River Pollution

Remediation– Case study of Liuchuan River

Che-Yu Hsu, Sheng-Jung Ou


Abstract. The Liuchuan River is an urban river in Taichung City of Taiwan. It was been

affected by the pollution of domestic sewage and commercial wastewater for many

years, resulting in the degeneration of water quality in rivers. Because of the hard

bank revetment along the coast, the urban blue ribbon are unable to interact with

residents. In order to improve water quality pollution and waterway environment,

the Taichung Water Resources Bureau prioritizes water quality improvement. Under

the goal of ensuring flood control and drainage, it actively diversifies the waterway

space to enhance the city's local culture and life value. The purpose of this study is to

analyze the improvement of water quality through the discussion of low-impact

development engineering remediation projects. The water permeability of the

riverbank before repair is almost 0%. After the improvement, the water permeability

is increased by 50%, the green area is increased by 3,322 square meters, and the

water quality RPI index is reduced from 7.25 "serious pollution" to 5. "moderately

pollution". This result shows that the Liuchuan River remediation project has

successfully improved the water quality and river channel. Re-injecting green

elements to create a hydrophilic environment for urban blue-green belts, improving

the quality of residents' living environment, and promoting the benefits of

surrounding businesses and tourism.

The use of faba-bean cropping as a sustainable and energy saving technology – A

new protein self-sufficiency opportunity for European agriculture?

Rikke Lybæ k & Henrik hauggaard-Nielsen


Abstract. - European agriculture relies on large amounts of imported protein fodder,

primarily soya-beans, for livestock rearing from e.g. South and North America. This

has severe social and environmental impacts, and require large amount of fossil fuel

to cultivate, harvest and transport. This paper investigates how faba-beans - a

leguminous crop able to fixate its own nitrogen through symbiosis with soil bacteria

while providing various other Eco System Services - can be adopted, as a valuable

crop by farmers in EU. This could substitute import of soya-bean for animal fodder,

providing global savings in pesticide, artificial fertilizer and fossil energy usage.

Emphasizing transition theory and e.g. farm machinery, culture and policies, we

conclude, that activities must be applied at all levels of the agricultural system. New

transition pathways are e.g. to strengthen farm networks to share knowledge and

farm equipment for faba-bean cultivation, and to enhance the environmental

regulation to limit the amount of artificial fertilizer distributed on farmland making

legumes more valuable for farmers.

A new predictive model for Plants Photosynthesis Influenced by Major Climatic

ZS Liu, WY Yang, XL Yu

Shandong Agricultural University, China

Abstract. Climate change, particularly global warming, is significantly affected by

atmospheric CO2 dynamics. Plant photosynthesis is capable of fixing a large amount

of airborne CO2 and converts it into vegetation biomass and thus alleviates the

greenhouse effect from atmospheric CO2. However, how climate change and climate

condition impact the dynamics of plant photosynthesis is still highly uncertain. Here

we combined high frequency land surface measurements of photosynthetic CO2

fixation data and information theory to understand the casual relationship from

climate drivers on the photosynthesis rate. We found that temperature and

shortwave radiation dominated photosynthesis more at forest site, while

precipitation dominated photosynthesis more at grass land site. More importantly,

linear regression based analysis failed to identify such relationships, which confirmed

the important role of information theory in identifying nonlinear relationship within

a complex system.

Environmental improvement Strategy of Urban Green Farm Garden: a case study of

Dongguang Green Garden Road, Taichung City

Meng-Li Lin, Rui-Xing Yang


Abstract. Amid rapid urban growth, the inhabitants of Taiwan’s ‘concrete jungles’

have tended to neglect the protection of natural resources, and to engage in

Session

41

activities that emit large amounts of carbon dioxide. The urban heat island effect also

remains a serious problem, only partially addressed by urban green spaces created or

protected via intergovernmental urban planning. Nevertheless, Taiwan’s cities still

contain many small areas of wasteland – both the sites of demolished buildings, and

former green spaces that have been allowed to die off. If transformed into urban

gardens and/or farms, this waste ground could meet the public’s need for additional

green spaces and experiences, and help to gradually improve their quality of life.

Plans and mechanisms to that effect have existed since 1990, and Taipei City was the

first place in Taiwan where farmers provided land for urban dwellers to cultivate.

However, due to insufficient governmental support, the operation and management

of such initiatives has been largely ineffectual, and thus their development has not

been sustainable. Therefore, this paper uses Dongguang Green Garden Road in

Taichung as a case study of this sustainable-development bottleneck, with the wider

aim of increasing the quantity and quality of urban agricultural gardens in Taiwan and

beyond.

Study on Cost Performance of Gain and Payback Period in a Plant Factory of Spinach

in a Cold District

Naoki Kikuchi and Shin’ya OBARA

Kitami Institute of Technology, Japan

Abstract. Energy supply and demand of a plant factory facility on our campus were

investigated for the purpose of energy saving in a cold region plant factory with

renewable energy. The average value of the highest temperatures in November to

March is 20 degree Celsius or less in Kitami. Therefore, the environment temperature

of the plant factory was adjusted to 20 degree Celsius by air cooling with a

ventilation fan. In addition, by supplying surplus heat of cogeneration to an external

greenhouse, an increase in the harvest volume of spinach was expected. Moreover, a

facility consisting of a cold region plant factory and a greenhouse is defined as a

"plant cultivation system". When spinach is cultivated in this system, cost

performance of gain is 2.57 (price of farm products to production costs) and the

payback period is 9.70 years, so a general introduction can be expected.

positive effects for local redevelopment. This study, therefore, reviews the relevant

literature on eco-village, and proposes a redevelopment strategies framework for

eco-village based on that review and a two-stage questionnaire administered to

experts. The first stage utilized the Fuzzy Delphi Method, which focuses on impact

factors, and the second, the Analytical Network Process Method, deals with

performance factors. The results indicate that the key impacts on the ecovillage

redevelopment strategies for Jianguo military dependents’ village were (2.1) water

Thammasat University (Lampang Campus), Thailand

Abstract. Dyes are widely used in various industries. It is significant to remove dye

from wastewater before discharge. Adsorption onto activated carbon is more than

beneficial than the other traditional methods as a result of its high adsorption

capacity for coloured particle. The main objective of this study is to prepare activated

carbon from elephant dung (EDAC). The adsorption performance of EDAC was

studied by conducting batch adsorption experiments. The adsorption data are

correlated with Langmuir and Freundlich under various conditions methylene blue

(MB) concentration and contact time. The optimum dosage of EDAC was found to be

100 mg. EDAC adsorption was fitted with Langmuir model. The calculated maximum

adsorption capacity was 18.98 mg/g. A dimensionless separation factor (RL) indicated

a favourable adsorption of MB onto EDAC. The study indicates that EDAC could be

employed as a cost-effective alternative adsorbent for removing MB from

wastewater streams. EDAC also was cheap, more eco-friendly and effective waste

utilization.

Constructing a Framework for Economic Value of Urban Renewal in Taiwan

Kuo-Wei Hsu and Jen-Chih Chao


Abstract. Following a phase of early prosperity, Taiwan’s urban centers have slowly

declined, resulting in the hollowing-out of business districts and declining

populations, and prompting widespread interest in urban redevelopment. To

improve the quality of urban environments, not least in terms of disaster

prevention, the central government's urban-renewal policy is aimed at re-inspiring

local development via the introduction of funds and dynamism from the private

sector. However, progress has been slow because potential private-sector partners

tend to measure projects’ merit and performance chiefly in financial terms, and the

economic value of urban renewal remains notoriously difficult to quantify.

Accordingly, this study proposes a complete economic-value framework for urban

renewal in Taiwan through secondary-data methods. Specifically, this framework

consists of three facets and six factors, of which the land-use value facet (comprising

the land and real-estate value factors) relates to the strength of the local economy;

the energy-conservation value facet’s two factors are energy-use and

carbon-emissions reductions; and the disaster-prevention value facet consists of

Taichung City’s Management Strategy for Leisure Cycleway Maintenance: A Case

Study of Gaomei Cycleway

Yu-Chen Chien, Sue Yee Yew


Abstract. In an era marked by global warming, energy conservation and carbon

reduction are increasingly prioritized by national and local governments, companies

and individuals. The bicycle is emerging as an important tool for reducing the overall

volume of traffic, protecting the environment and conserving energy, as well as

improving individuals’ health and relieving their stress. Therefore, environmental

demand for cycleway is garnering increased attention. The cycleway built by

Taichung City’s government include the Gaomei Cycleway, a coastal route famous for

its seascapes and sunsets, and surrounded by rich ecological resources. This study

uses Gaomei as a case for exploring the city’s maintenance and management

strategies for its cycleway. Specifically, it looks at the varying demands placed on

Gaomei and the system in general by leisure users and commuters.

Importance-Performance Analysis (IPA) was used to review bikers’ strategy

recommendations generated from a questionnaire covering four facets: safety,

continuity, service facilities, and environment. The results of IPA indicate that bike

commuters give more weight of the safety and continuity facets due to the high

Cross-city PM2.5 predictions with recurrent neural network

RuoHan Zong, TongYuan Zhang, Zhi Chen, Yi Zhu

Sichuan University, China

Abstract. PM2.5 is inhalable particulate with a diameter less than 2.5 M that

easily enters the lungs and causes diseases and non-accidental death. The

generation and dissipation of PM2.5 are strongly affected by a variety of

environmental factors, thus the concentration of PM2.5 is presumably predictable

with the observations of environmental conditions. This paper used multi-year

meteorological and PM2.5 concentration data across multiple megacities in China

(Beijing, Chengdu, and Shenyang) and sought for a universal predictive model. Our

results showed that data-driven machine-learning model was able to not only

capture PM2.5 dynamics at the city where the model was trained but also could be

generalized to predict PM2.5 concentrations over other cities. Therefore, the

modeling results indicated a universally existing predictive relationship between

PM2.5 source-sink dynamics and the environmental drivers.

both leisure and basic transportation has increased the importance of public

bicycle-related infrastructure, notably cycleways. This paper proposes a Design

Optimization Index for two types of cycleways, i.e., those that are used primarily for

commuting, and those that are mostly for leisure. Based on a literature review, the

researchers initially developed 27 impact factors. Then, through the fuzzy Delphi

method of collecting and refining advice from a group of experts, these were

integrated into a five-part structure consisting of “security”, “convenience”,

“environmental friendliness”, “comfort” and “attractiveness”, which can be further

broen down into 16 factors in the case of commuter cycleways, and 15 factors in the

case of leisure cycleways.

Abstract. During the 2014 Youth Olympic Games in Nanjing, the local government

implemented a series of emission control measures. Fixed-effect model and

generalized additive model were conducted to evaluate the association between

control measures and health benefits. Daily non-accidental mortality decreased

from 71 deaths per day before taking control measures to 61 during the

under-control period. Interim measures reduced SO2, NO2, PM2.5, PM10 by 6.63%,

12.96%, 8.72% and 10.30%, while comprehensive measures further reduced

pollutants by 12.19%, 8.89%, 25.05% and 30.86%. A 10μg/m3 decrease in SO2, NO2,

PM2.5, PM10 was associated with decreases in all-cause mortality of

2.91%(95%CI:1.57%,4.24%), 1.36%(95%CI:0.62%,2.11%), 0.55%(95%CI:0.23%,0.87%)

and 0.39%(95%CI: 0.15%,0.62%). According to the calculation, the game specifically

reduced about 1000 acute deaths from all cause and produced about 500 million

USD of benefits, demonstrating a statistically significant association between air

quality controls and health benefits. The result also shows that relevant controls to

deal with NO2 and PM should be taken more stringently in heavily polluted cities.

Modelling

Priyambodo Nur Ardi Nugroho and Shuichi Torii

Kumamoto University, Japan

Abstract. Energy efficiency is crucial for many developing countries, including

Indonesia. One of the solutions is to shift fossil fuels to an alternative source of

energy, like biomass which is also available abundantly. Biomass conversion

technique like gasification using palm empty fruit bunch is essential considering its

potential in Indonesia. Advanced technology with cost effective and highly

efficient gasification process is required to promote this method, especially in rural

area. Computational analysis for design and initial study is mandatory because

gasification involves complicated chemical reactions. Biomass gasification

characteristic was investigated using Computational Fluid Dynamic (CFD) program

STAR CCM+. The Eulerian Lagrangian concept was employed to model the gaseous

phase (air) and solid phase (biomass particles) of biomass gasifier accordingly.

Each of the gasification syngas formation - i.e., CO, N2, CH4, and H2 respectively -

were analyzed. The objective of this paper is to characterize biomass gasification

steps started with drying, thermal decomposition/pyrolysis, partial combustion of

gases, vapor, and char, and finished with the gasification of decomposed products.

University Of Perpetual Help System Dalta Las Piňas Campus, Philippines

Abstract. The study focuses on the integration of the darrieus and savonius wind

turbine to a vertical axis wind turbine for power generation. The material used for

darrieus was fiber glass with three blades and diameter of 350 mm, and polyvinyl

chloride (PVC) for the savonius with four blades and diameter of 100 mm. The

evaluation was conducted using a controlled wind source to vary its linear wind

velocity. The actual power generated was compared to the theoretical power

generated to identify the efficiency of the system. With the lowest linear wind

velocity of 2.63 meters per second, the actual power output of the system

(combination of the darrieus and savonius power output) was 3.79 watts and the

theoretical power output is 6.03 watt. This made the system to be 62.85% efficient

with low wind velocity. With the highest wind velocity of 12.52 meters per second,

the output of the system was 408.80 watts and the theoretical output is 650.61

watts. This made the system to be 62.83% efficient. In an overall performance of

the system with varying linear wind velocity, the efficiency of the system is close to

63%.

Abstract. This study investigated application of photovoltaic (PV) panels for office

building. Bandung, Indonesia is chosen as case study due to its hot and humid climate.

To conduct this study, first, site selection was evaluated, followed by load evaluation

using standard requirement for energy-efficient office building. Then, design and size

of the system was defined. Feasibility of this study was evaluated from technical and

economic indicators, i.e. energy delivered, energy export and import to the grid, yearly

savings, and payback period. Simulation of this study was performed with various

scenarios on the design electricity load. This study shows that solar PV panels are

feasible to be installed in flat roofs and western façade. With 365 m2 of solar panel in

total, it can generate 66 MWh electricity per year. If PV provide electricity for lighting

inside the building, the payback period is 12 years. This payback period become faster,

i.e. 6.24 years, if all the electricity is sold to the grid.

Conversion of Carbon Dioxide into Storable Solar Fuels Using Solar Energy

Houda Ennaceri and Bernd Abel

Leibniz-Institut für Oberflächenmodifizierung, Germany

Session

Abstract. Nowadays, there are two main energy and environmental concerns, the first

is the risk of running out of fossil fuels in the next few decades, and the second is the

alarming increase in the carbon dioxide concentrations in the atmosphere, causing

global warming and rise of see levels. Therefore, solar-driven technologies represent a

substantial solution to fossil fuels dependence, global warming and climate change.

Unlike most scientific research, which aim to use solar energy to generate electricity,

solar energy can also be harnessed by recycling the carbon dioxide in the atmosphere

through high-tech artificial photosynthesis with the objective of producing storable

and liquid solar fuels from CO2 and water. There are two types of solar fuels, the first

being hydrogen, which can be produced by mean of water splitting processes. The

combustion of hydrogen generates water, which is a completely clean option for the

environment. The second type of solar fuels consists of carbon-based fuels, such as

methane (CH4), carbon monoxide (CO), or alcohols such as methanol (CH3OH) and

ethanol (C2H5OH). The production to liquid solar fuels liquid fuels is of great interest,

since they can be used in the current industrial infrastructures such as the

automobiles’ sector, without substantial changes in the vehicles’ internal combustion

engines. Therefore, guaranteeing a smooth transition from fossil fuel energy to

renewable energy without radical economic consequences. Also, and most

importantly, when these solar fuels are burned, they will only release the exact

amount of CO2 which was initially used, which represents an optimal process for

sustainable transport.

evacuation centre during power shortage or blackouts in a flood disaster situation.

However, it is a challenge to connect this technology to the local communities,

especially for the rural people due to the limited accessibility of the technology. Strong

support from the Government is needed in disseminating this technology for the

locals, especially during a flood disaster where victims need the power aid relief during

the power interruption. By using solar technology, the power can be generated and

stored ahead of time at the flood relief centre. This paper will investigate on the

perception of rural communities in Malaysia; focusing FELDA communities, in

connecting the solar electrification during a flood disaster. The significant approaches

for connecting FELDA communities with solar electrification need to be explored

strategically. In order to investigate the acceptance of FELDA communities in

connecting solar electrification in the flood evacuation centre, survey research

through questionnaires has been obtained from the respondents. Interestingly, the

result shows that the back-up electricity supply system is needed in order to

accommodate the electricity supply at the evacuation centre when flood occurs. The

research found that the local people are ready to use the solar electrification as a

supportive electricity system during flood disaster. This paper has elaborated on the

significance approaches towards connecting people with the technology.

B Triasdian, Y S Indartono, N S Ningsih and D Novitasari


Abstract. One of the promising renewable energy sources that has a high energy

density is ocean wave energy (OWE). By using the average wave energy data of

21-year WAVEWATCH-III (WW3) model, some areas were discovered to have a great

potential for the wave energy generation. This present study was evaluating the

selected Wave Energy Converters (WEC) and determining their capability to do the

energy capture in the potential site of the Indonesian seas. The data of WW3 indicate

the energy flux of OWE in Indonesia reached to 74.65 kW/m. The case study was

conducted in the present research placed in an area of the Java Island called Cidaun,

with energy flux about 42.41 kW/m. One of the Heaving Device type was used for

assessing the practical energy and to analyze its development in Indonesia with certain

limitations; a single round float and diameter device about two meters. The annual

energy extracted from the designated WEC was approximately reached 119 GWh.

Furthermore, the levelized cost of energy (LCOE) was assessed for the particular device

in the selected site, resulted about 25.13 $cent/kWh or four times higher than a

standard of minimum feed in tariff given by the Indonesian government.

Abstract. The aim of this project is to design a novel solar powered air-conditioning

sys-tem that operates under UAE climate conditions. Various passive techniques and

Nano-technology were incorporated to enhance the system performance. A detailed

analysis of the proposed design is presented in the paper. The passive techniques used

were roofing reflective material, trees, double glazed windows and overhang.

Furthermore, the single wall carbon nanotube (SWCNT) was dispersed with the

refrigerant. Results suggest that the proposed design of using passive techniques

reduces the cooling load on the space by 31.5%, and the usage of nanoparticles with

the refrigerant reduces the work of the compressor by providing a uniform and

comfortable temperature at about 23oC inside the room. Finally, comparisons

between the proposed and conventional system had been carried out. Results

demonstrate that the COP of the proposed system was found to be about 3.64 which

is higher at about 4% than the conventional air condition system.

Feng Chia University, Taiwan

Abstract. According to statistical analysis human beings spend about 80% of

their lives indoors, the studies of indoor air quality (IAQ) is of great concern. The

ability of bioaerosols to cause human disease depends not only on their

chemical composition and biological characteristics, but also on the quantity of

bioaerosol inhaled. Biomass quantification by traditional “cultivate-based”

microbiological determination method usually results in under estimation. In

this research we are to investigate the complete composition of bioaerosols

with molecular cloning and next generation sequencing approaches and the

potentially existing pathogenic microorganisms or endotoxin in the bioaerosol

samples collected from the library and kindergarten in the middle of Taiwan.

Each bioaerosols sample from different indoor environments was randomly

obtained from the next generation sequencer for 80,000 to 120,000 DNA data.

The specific composition and proportion of each bioaerosols samples are

analyzed by compared to the NCBI database. The results show that the

composition of biological aerosols major determined by different types of

indoor space has its own unique characteristics. We also observed human

activities also an important factor influencing the immediate change of

bioaerosols composition. This study can provide the basis knowledge for

improving indoor air quality.

wettability alteration in carbonate rocks

C Ho and M A Ayoub

Universiti Teknologi PETRONAS, Perak Malaysia

Abstract. Low salinity water flooding is one of the emerging enhanced oil

recovery technologies as it has been proven economical and environmentally

friendly. However, the recovery mechanism of low salinity water (LSW) is still

under debatable due to the complex effect of low salinity water and its ionic

compositions. Therefore, this study aims to discover the optimum seawater

dilution salinity and influence of single and binary ionic compounds’ low salinity

water on wettability alteration of carbonate core slices at optimum salinity. To

achieve that, a modified Design of Experiments (DOE) has been implemented.

Contact angle measurement was carried out to characterize the wettability of

core slices at 0 hour, after 24 hours and after 48 hours. The results revealed that

dilution of seawater reduced the contact angle of carbonate core slices towards

more water wet until the optimum salinity of 1750ppm. Further dilution to

700ppm only shown a slight impact in shifting the wettability of the carbonate

slices towards more water wet. In single ionic compound LSW, MgCl₂ showed

the greatest ability in altering wettability. In binary ionic compounds LSW, it was

found out that MgCl₂ mixed with ionic compounds containing monovalent ion is

more effective in altering contact angle than MgCl₂ mixed with ionic compounds

containing divalent ion which serve as a new finding in current low salinity

water study on carbonate rocks.

SK2-015 A customization-oriented carbon footprint service for mechanical products

Yajun Zhang, Jianjun Yi, Zhuoran Wang and Liang He

East China University of Science and Technology, China

Abstract. As the growing concerns of global warming, carbon footprint of a

product becomes an important designing criterion. In recent years, the issue of

product carbon emission has been extensively studied and most research focus

on the computing method, life cycle assessment and optimized design of single

category product. However, a lack of versatility in these existing research

programs make them difficult to be applied in other product. Furthermore, in

many cases, target customers are not concerned about carbon emissions

throughout the life cycle of the product and full-cycle calculations of carbon

emissions make no sense. To fill this gap, a service mode to provide

quantification of carbon footprint for mechanical products is presented in this

work. The multi-scale and full-direction system, which is based on process chain

employing multiple scale task model, is proposed to meet the different carbon

footprint requirements, and then encapsulate it as a service to the user.
