We asked ourselves, should we publish Inspired to

be GREEN as a paper magazine or should we just

send it out as an email? Wouldnt it make sense to

send it digitally with zero emissions? We would avoid

deforestation by not printing and then prevent further

pollution caused by the distribution. Then again, you can

make a much bigger difference by reading, learning and

implementing green in your buildings and in your life...

Here are the reasons why we think printing would make

a bigger difference:

We are living in a time where everyone is busy and

time is the most valuable good. To read information

from paper is better for your eyes and you can take our

magazine wherever you like.

Whenever you get a free minute, pull it out, and get

to know the latest & greatest green news and a whole

lot of information that would help you in the design &

construction of green buildings.

Take the rst action and just read it, and then tell others

to read it too.

Inspired to be GREEN will make you think of a

healthier planet and a greener future. If you take just

one action to be greener, make greener products, use

renewable materials or invest in green technology

then you can easily offset 10, 100 or 1000 times the

emissions caused by printing this magazine.

After you read the magazine you can give it for

paper recycling or you get very creative and make

something useful out of it. We hope that you love our

magazine and collect the issues or hand it over to other

people, to share the knowledge.

We put all our passion for green and our love for mother

earth in creating this magazine, and we hope you will

enjoy reading it.

Their role in a green building project, benets of having one on the team and how

to become one yourself

Who is a LEED AP and what is his role?

The LEED AP credential signies an extraordinary depth of

knowledge in green building practices and specialization in a

particular eld.

A LEED Accredited Professional is an individual who has shown

adequate knowledge and experience in the eld of green building and

LEED certication of projects, by passing the LEED AP examination

administered by the Green Building Certication Institute.

The LEED AP is a pivotal person in the green building design and

construction and leads the effort to meet the criteria and credits

isted by the LEED rating system. The LEED AP also helps the team

coordinate and complete the documents and calculations required

to meet the requirements of each credit in the format prescribed

n the LEED reference manual. He forms the link between project

team and USGBC to clarify any project specic questions.

The greatest benet, of course, is a more streamlined and hassle

free certication process and a go to person for any questions that

usually arise.

The New LEED AP Exam:

The Green Building Certication Institute has launched a new

exam and credentialing program. It has become a 2 step process to

become a LEED AP+ and is explained in great detail.

GBCI has now introduced 3 levels of Accredited Professionals.

1. Level I LEED Green Associate

2. Level II LEED Accredited Professional with specialty

3. Level II LEED Fellow

the requirement for any

new industry in India

Green Factories...

We are all well aware that industry forms the backbone of our Indian

economy. Watching so many movies about global warming and climate

change, one is almost led to believe that industrial development is the

culprit and should be curtailed. How can sustainable development be

possible when our economy is growing at such a fast pace and the local

and internaonal demands are so high?

Green Factories in India:

Why is this so important?

Factory related pollution is the number one source of pollution in the

World. Factory pollution accounts for more than half the volume of all

water pollution, as well as for the most deadly of pollutants.

Most of the manufacturing factories consume vast quantities of fresh

water to carry away wastes of several different types. This waste water

from industrial factories is discharged into lakes, oceans and streams,

which eventually disperse the polluting efuent substances.

Construction related factory discharge includes gypsum, metals,

cement, abrasives and poisonous solvents which pollute air and water

and the negative effects are seen in cities all over the world. Power

plants cause thermal pollution when they increase water temperatures.

These increases of temperature affect the amounts of oxygen that

are suspended in a volume of water. Changing the oxygen level of water

disrupts the ecological balance of a body of water. This can kill animals

and plant species, at the same time it encourages the overgrowth of

other plant and animal species.

Factory pollution includes carbon monoxide, which is mainly produced in

combustion processes. Though most carbon monoxide pollution comesfrom motorized vehicles, there are also many combustion driven power

plants still in operation today.

Factory pollution includes chlorouorocarbons, which have been shown

to destroy the ozone layer. Hydrocarbon gases and nitrogen oxides are

frequently emitted by industrial factories.

Sulfur oxides cause acid rain and come from the burning of fuel that

contains sulfur. Sulfur oxides are mostly produced at power plants or

even combustion-driven power plants.

Other types of pollutants that are known products of factory waste

nclude volatile organic compounds like solvents, gasoline, petroleum

products and cleaning solutions.

The answer is Green

Factories. When designed,

constructed and managed

in an environmentally

sensitive manner, these

factories can reduce

the negative impact on

the environment. Here

are some facts about

industries that should make

you realize that we are

currently developing in an

unsustainable manner and

change and improvement is

our only option.

With the advancement of t he green building movement in India, many companies have evinced keen inter-

est in having a holistic green design and construction framework for new factory buildings.

IGBC, in its endeavor to extend green building concepts to all building types has developed the IGBC Green

Factory Building rating system. IGBC Green Factory Building rating system is the rst of its kind addressing

sustainability in industrial buildings. The programme is fundamentally designed to address national priori-

ties and quality of life for factory workmen.

IGBC Green Factory Building Rating System is a voluntary and consensus based programme. The rating

system has been developed based on the contemporary materials and technologies. It would facilitate

the development of green factories. The rating system evaluates certain credit points using a prescriptive

approach and other credits on a performance based approach. IGBC green factories have evolved so as to

be comprehensive and at the same time user-friendly.

The pilot version of the rating system has been launched on 10th July 2009. Project teams interested in

IGBC Green Factory Building Certication for their projects must register with IGBC. Benets of Green Factory

Buildings include energy savings from 30 40 %, water savings around 20 30%, enhanced indoor air

quality, good day-lighting and hence increased productivity, health, wellbeing and safety of the work force,

reduced dependency on virgin materials and reduced use of fossil fuels.

The Kyoto Protocol formed under the United Nation

Framework Convention on Climate Change (UNFCCC)

allows the Annex I countries of the UNFCCC (the

developed countries and countries with economies

in transition) to reduce their greenhouse gas (GHG)

emissions by a certain amount. The Protocol was formed

in 1997 and it came into force on 16th Feb 2005. This is a

legally binding agreement for 169 industrialized nations

to collectively reduce their GHG emissions to about 5 %

from 1990 levels. The 1990 emission levels have been

taken as baseline. In the 2008-2012 phase of the Kyoto,

the legally bound countries will achieve their targets.The six GHG gases identied in the Protocol are CO2,

CH4, HFC, PFC, SF6 and N2O. It is under the Kyoto

regime that the largest GHG market in the world has

evolved.

Clean Development Mechanism, dened under Article 12 of the Kyoto Protocol, is aproject based transaction system which allows industrialized nations, having a target for reduction of

GHG, to accrue carbon credits.

A CDM project should assist Non Annex Party/country (developing nations) in achieving sustainable

development. Projects such as energy efciency, fuel switch, renewable energy (hydro power, wind

power), methane capture from municipal solid waste, waste to energy, HFC destruction, biomass and

cogeneration, which help in reduction of GHG emissions could be potential CDM projects.

Carbon credits are acquired by nancing the carbon reduction projects in developing nations. The

credits originating from such projects are termed as Certied Emission Reductions (CERs). For every

tonne of carbon dioxide reduced, one CER is issued which is then traded in the international market

such as the EU ETS. The CERs can also be sold in the voluntary carbon market. In 2006, the CDM

transacted credits valued at around US $5 billion and represented reductions of 450 Mt CO2e.

There are three mechanisms under the Protocol through

which the Annex I countries can reduce their emissions.

These mechanisms form the foundation of the Kyoto

Protocol. They are as follows:

Clean Development Mechanism

Joint Implementation

Emissions Trading Source : www.emergent-ventures.com

Joint Implementation allows emitters in the developed (Annex I) countries to purchasecarbon credits from another developed country or an economy in transition that have implemented

carbon reduction projects. This is also a project based transaction and reductions achieved through

such projects are referred to as Emission Reduction Units (ERUs). Some of the countries involved in JI

are Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Poland, Romania, Spain, UK, etc. Any

project starting after the 1st January 2002 is eligible to be a part of JI.

Global climate changewe are living in midst of constantly changing climatic conditions,largely a result of human interference,and it allowed to continue can cause irreparable damage to

ora, fauna and human life. The rise in the average temperature near the earth's surface, by the use of

fossil fuels such as coal, industrial and agricultural processes is scientically termed as global warming.

Warming tends to change climatic patterns across the globe resulting in the notorious problem of global

climate change. Global Climate Change as the term suggests is a global issue and is not restricted to

the activities of particular individual, community, zone, region, state or country.

These mechanisms allow such countries to reduce their emissions by funding/implementing project

activities that reduce the GHG emissions in other countries. The rationale behind having such exible

mechanisms is that climate change is a global phenomenon and carbon dioxide reduced at one place

will have a net positive impact in GHG reductions across the globe.

Emission Tradingis an allowance based transaction system which permits Annex I countries topurchase carbon credits from other Annex I countries to fulll their emission reductions commitments.

The European Union Emission Trading Scheme (EU ETS) is a resultant of this mechanism and is currently

the worlds largest multi-national GHG trading scheme. Credits under this system are known as

European Union Allowances (EUAs).

GREEN with GRIHA

GREEN...And its Growth in the

Indian Market

The Energy and Resources Institute...towards global sustainable development

Do you ever fancy travel by a time-machine, back and

forth in time? I do. When I watch epic movies like Troy or

Gladiator, I feel like traveling back in time to see how the

Acropolis was built by the Greeks, the Colosseum by the

Romans etc., and to understand the processes of thought

that lead to events that changed the course of our history.

My curiosity further deepened when I visited the historical

theme park, Puy du Fou in the Vendee region of Western

France. Small pockets of the park recreate ancient Europe

from different historical times. Apart from the spectacular

shows featuring the Viking attacks, Gladiatorial combats,

Equestrian feats etc; the architecture and the way of life

from medieval times was quite thought provoking. It is a

model of sustainable living showcasing men and women

gainfully engaged in various vocations; living on agriculture,

livestock and entertaining them with live music.

wondered why such content people would transform into an industrial society. A possible explanation is

that the conditions of life I witnessed in August were limited to the spring season and the weather during

the rest of the year was quite harsh. Their typical food like cheese, sausages, wine etc., can be stored for

months. It was not difcult to imagine that they had to ght against or control nature for most part of their

ives to better their standards of living.

However the Indian situation is quite different. We experience sunshine all round the year and are endowed

with abundant natural resources. Historically our lifestyle was in harmony with nature. Perhaps we have

been digressing from this approach in recent times. Shortage of energy and water, waste disposal, pollution

of air are the order of the day in most par ts of our urban areas. Unless we learn from our mistakes, history

repeats itself. When it comes to designing buildings we have a choice between the [1] new controlling

nature paradigm by adding active systems for lighting, space conditioning and vertical transportation or [2]

the time tested harmony with nature paradigm by engaging nature through passive design to achieve day

ighting, space comfort and resource conservation. Due to t he differences of climate in a country like Indiaand the variety of uses in buildings, both approaches are relevant. With increasing concern over climate

change, sustainability has become the most important agenda for all types of development. Building design,

construction and operation which addresses sustainability has been labeled green, eco-friendly, sustainable

etc., in different parts of the world.

Market driven sustainability initiatives such as green building rating programmes have popularized

green buildings in the west. Enthusiastic corporate houses from India have built green ofce buildings

that have achieved the highest levels in such rating programmes. This has become a trend and

opened a new market for green building services. TERI has worked on the Energy Simulation of these

pioneering certied green buildings and already had many years of research experience in sustainable

buildings. With a combination of research excellence and experience with international green building

rating approach to market transformation, TERI has come up with a green building rating programme,

TERI-GRIHA, Green Rating for Integrated Habitat Assessment. While the idea of having a rating systemfor green buildings is not pioneering, the approach of connecting each green project to t he context of site

viz, the local physiographic conditions, agro-climatic conditions, construction materials, construction

practices and optimizing the functionality and performance of the building through a combination

of passive and active systems is unique. TERI-GRIHA is a framework of inter-related environmental

performance criteria that serve both as directions for designing, building and operating a green building

project and standards for measuring the overall green performance of a building project.

TERI has the unique advantage of working closely with the government, industry, donor agencies and

various strata of civil society. TERI-GRIHA was thus conceived with the inputs and feedback from across

these stakeholder groups. The performance standards have invariably been linked to the available

national standards by the BIS (Bureau of Indian Standards) or directives and codes from the concerned

ministry. TERI-GRIHA was developed for India with National priorities at the core of each criterion in the

rating system. TERI-GRIHA sought to popularize compliance with the Indian codes for construction. As

a part of Government of Indias commitment to sustainability and mitigation of climate change, it has

come up with the NAPCC (National Action Plan on Climate Change) which organizes the plan of action

into eight missions. These missions offer directives for t he concerned ministries for chalking out their

specic action plans. Again TERI played a key role in the development of the Mission on Sustainable

Habitat The Ministry of New and Renewable Energy (MNRE) has identied the various rating systems

in India and through a competitive process, selected TERI-GRIHA for adoption as the national rating

system after minor changes in the rating system.

The following aspects of the building design are looked into in an integrated way in a green building:

Site planning

Building envelope design

Building system design (HVAC, lighting, electrical, and water heating)

Integration of renewable energy sources to generate energy onsite

Water and waste management

Selection of ecologically sustainable materials

Indoor environmental quality

Commonwealth Games Village: GRIHA principles when applied to large projects can signicantlyreduce their environmental impacts and ensure long term viability of such developments. GRIHA rating not

only helps create good Indoor Environmental Quality for future occupants but also mandates safe and decent

working conditions for the construction workers. This project which is on its way to get GRIHA certication

has received special appreciation from the Ministry of Labour, Government of India for creating conducive

working environment for the construction workers like on-site accommodation including sanitary toilets, safe

drinking water and protective equipment for work.

GRIHA is suitable for designing all types of new green buildings irrespective of their functionalitywhether residential, commercial, institutional, hospitality, health care or retail. Around 28 projects from

many of the above categories have registered with TERI for TERI-GRIHA rating. IIT Kanpur, Environmental

Sciences and Engineering block has been provisionally rated as a 5 star rated building. The others are

under various stages of progress. New projects will be registered under GRIHA. Projects registered under

TERI-GRIHA which are under progress have the option to migrate to GRIHA.

GRIHA will now be administered by an independent entity to facilitate a truly 3rd party certication and

verication of green building projects. GRIHA is being registered as a not-for-prot society. The Ministry of

Renewable Energy has given the seed funding for setting up an independent secretariat. GRIHA secretariat will

be located in the TERI University, Vasant Kunj, New Delhi. The secretariat will be the public face for GRIHA

rating. An online platform will be available soon on t he GRIHA website for all projects to submit their project

documents online for certication review. GRIHA secretariat would coordinate from end-to-end for project

certication through the registration of project, orientation cum training workshop, document review, site

visits and nal award of rating. GRIHA has already announced a training programme for experienced green

building professionals who intend to be evaluators of GRIHA project certicat ion documents. These evaluators

would be bound by a non-disclosure agreement in relation to the review work that they will be doing forGRIHA as third-party evaluators. The nal award of r ating for each GRIHA certied building would be subject

to the approval of the National Advisory Council.

The secretariat would work closely with the

Technical Advisory Committee (TAC), National

Advisory Council (NAC), TERI Building Sciences

Group and MNRE in propagating GRIHA amongst

various stakeholders, updating of GRIHA rating

system, development of GRIHA rating system for

operational buildings and organizing outreach

programmes through events. TAC and NAC are

national level bodies constituted by eminent

building professionals, industry representatives,

policy makers and domain experts. GRIHA seeks to

engage stakeholders at all levels in promoting green

buildings. A suitable membership mechanism for

formal engagement in promoting GRIHA will be

worked out. After having a critical mass of green

building professionals engaged in GRIHA projects,

professional accreditation shall also be introducedto benchmark the service delivery for GRIHA con-

sulting assignments.

TERI GRIHA with the following changes

has become GRIHA, the national green

building rating system.

1. Inclusion of a mandatory criterion

on site selection.

2. Inclusion of an optional criterion

on universal accessibility of common

spaces (barrier free design to enable

access for the differently-abled)

3. Modication of the optional

renewable energy criterion and

making a minimum renewable energyproduction mandatory for all GRIHA

projects.

IIT Kanpur:GRIHA rating system can be applied to stand alone buildings coming up in inll plots in a developedarea or a campus. The Environmental Sciences and Engineering block in IIT Kanpur is an excellent example where

GRIHA rating process has helped to bring down the energy consumption by 60% vis-a-vis a similar building with

conventional specications. The project also preserved all the existing trees by designing the spaces around them and

integrating those spaces as internal courtyards thus adding to the solar passive feature set of the building.

Why Carbon Minus?Neutral is just OK, but not enough, says the Indian school of thoughts.Eastern faith and believe differs here with west. Our excessive wastefulenergy use and over consumption had brought rise to an alarmingsituation now. There is only one earth handed to us by our forefathersand we have the moral responsibility of transferring it safely to ourchildren. The Survival Strategy is clear we need to adapt not onlyaggressive policies, but also actions in our own house.

Climate Change is occurring faster and faster; being detrimental to global development effortsand a substantial threat to sustainability of mother earth. Climate Change risks food-security,health, water resources and will further affect all parts of human life. Countries like India withthe dream of reaching double digit growth and ensuring poverty reduction are facing the peakof its development challenges right now. Temperatures in India are projected to increase up to50 0C by 2060, resulting in huge yield losses. An increased occurrence of extreme events such

as droughts, oods and cyclones have star ted to affect the poorest segment of the society. In thelonger-term, a one-meter sea level rise would displace millions of people in India, and the coststo build walls along the zones, vulnerable to sea level rise are deemed to be extraordinary high.Carbon Minus India (CMI) strongly believes that India must join the global efforts to mitigate,adapt and moderate climate change today, which in fact, is one of the prime national challengefor India, along with rest of the world.

At the macro scale, India is a low-intensity producer of CO2 emissions, in comparison with restof the world. Its per capita CO2e emissions are among the lowest in the world with around 1metric ton (MT) per person compared with 4 for the world average and 20 for the United States.India also performs very well, when compared to other economies on the basis of CO2 intensityon per capita GDP i.e. tons of CO2 emissions per unit of GDP.

To evaluate or predict how much energy a building uses, can be a complicated process. There are some

thumb rules and experts can give a good idea of the approximate consumption of a standard building, but

these calculations do not work well if you want to design a green and energy saving building. Computer

Simulations are necessary to get an objective and precise idea of the buildings energy requirements and

also to understand the most cost effective energy conservation measures for the particular project.

Where is the energy consumed?

Do you know how much energy your building

consumes? To establish energy efciency measures

and save initial & operational cost, it is critical to

know what appliances and systems are using theenergy. The illustration shows how the total energy

consumption is consumed in a typical ofce building.

How do we start saving energy?

The process of energy conservation is to rstly reduce the loads, and then start making the systems more

efcient. The chart alongside shows the largest consumers and this is the right place to start: Cooling/

Heating, Lighting and Miscellaneous Equipment (Process Loads, Equipment Loads from Plug Points,

Computers and Appliances).

Heating & Cooling loads af fect their whole HVAC system. If cooling loads increase the energy requirements

are higher along with more electricity consumption for Ventilation Fans, Pumps and Heat Rejection. Cooling

oads can be reduced by improving the envelope system (Insulation of exterior Walls, high performance

glass, shading, green roof) and reducing the internal loads (efcient lighting system, efcient appliances).

To choose the right cooling system for your building is vital for efcient energy use. A centralized system

with water cooled chillers is efcient and efforts should be made to avoid using single split units which

consume much more energy.

Natural Light is the cheapest

form of lighting for a building, not

mentioning the many benets

t has on occupants health andproductivity. When articial light is

nstalled, ensure energy efcient

xtures but maintain the minimum

amount of light required for the

activity of the space. Occupancy

sensors and daylight sensors are

efcient lighting control measures

to ensure the articial lights

are turned off when there is no

occupancy or enough daylight.

Miscellaneous equipment can

be reduced by using energy

efcient appliances.

Computer Energy Modeling:How do you choose the correct Energy Efciency Measures for your project? Energy Modeling can give

you all the answers you need. The energy loads can be simulated, energy efciency strategies can be

modeled and the savings & payback calculated. There are a handful of Energy-Simulation softwares for

buildings like eQuest, EnergyPlus, Design Builder and VisDOE. For the following introduction to energy

modeling eQuest software has been chosen.

Step 1: Build an Energy ModelThe rst step for simulating the buildings energy consumption is to build a model in eQuest. To save time

and effort the model should be simplied as much as possible but it must be accurate enough to reect

the building design and energy consumption. Before starting with the program following information

must be collected:

- Design Basis Report (contains important data

like HVAC design, lighting, process loads,

temperatures, heat recovery, occupancy,

equipment density)

- Digital drawings (orientation, elevations, oorlayouts, zoning)

- Construction materials

- Rating system and requirements

- Applicable standards for simulation

(ASHRAE 90.1, ECBC 2007)

- Weather les for the proposed location

Simplied CAD drawings can be loaded in eQuest and used as background for drawing zones and construction

lines. Every single oor must be drawn except typical oors where multipliers can be applied. To calculate a

buildings energy consumption accurately and for meeting the requirements of LEED or IGBC a lot of detail

inputs must be fed into the soft ware. Specifying conditioned and unconditioned zones, occupancy, lighting

power density, equipment power density and fresh air requirements of every zone is vital. The HVAC System

can be chosen out of several options and detail inputs for pumps, chillers, fans and c ooling towers need to

be lled. It is also required to create and assign schedules for the occupancy, equipment and cooling period

as well as constructions for walls and windows. After the building parameters are entered, the simulation

report can be created which will give information about the annual energy consumption in Kilowatt hours

divided into HVAC consumption (Cooling, Heating, Fans, Pumps, Heat Rejection), Miscellaneous Equipment

(Equipment, Process Load), Exterior Usage and Lighting.

Step 2: eQuest Simulation &

Output Results:

eQuest gives the user opportunity to see a

detailed output le, where information of

systems, constructions, load hours, heat

gains and more can be gathered. With

this le, the tonnage of the system, wall

window ratio, solar gains, load hours and

room temperatures can be checked and

compared. Now the proposed case is nished,

but to apply for a Green-rating system a

base case still needs to be built. A base

case should reect an average building and

s simulated with the requirements given

n ASHRAE 90.1 or ECBC Code 2007. The

geometry in base-case remains the same

as for the proposed design only equipment

efciencies, conductivity of building

materials, HVAC-System, wall window ratio,

ighting power density and a few more

specications have to be adjusted based on

the energy code. The simulation program

performs the simulation for every hour of

the year, using weather data of the location

/city where the site exists, and hence the

results are comprehensive.

The real benet of computer simulation is

not only to predict the annual energy use

of the building, but to provide the team

with an understanding of the buildings

energy performance. This will enable

the team to select, simulate, validate

and nally incorporate energy efciency

strategies into the building.

Energy Efciency Measures and Validation through

Computer Simulation

The Results:

Energy Simulation is a very helpful tool to decide on different Energy Efciency Measures, and see the

mpact on the total energy consumption. The range of Energy Efciency Measures (EEMs) varies from simple

measures like building overhangs and adding insulation to more complicated systems like implementing a

BMS (Building Management System) and dynamic envelope system.

n this article, we have focused on a few Energy Efciency Measures, which range from simple, zero initial

cost strategies, as well as measures which come at a higher initial cost but have very good payback periods.

We have created a hypothetical building and simulate a Basecase which represents a typical ofce building,

n terms of design, envelope, systems and appliances/ xtures. Each str ategy is simulated individually and

the percent of savings are shown to validate the benets of the measure. A nal optimized case shows the

combined effect of implementing all suggested EEMs and the resulting total savings.

Total Energy Consumption

= 2979.8 kWh X 1000

Energy Consumption per square foot

= 11.9 kWh/yearTotal HVAC Load : 625 TR

HVAC Load (sf per TR) = 400

Strategy 1:

Working with the Sun, Orientation & Shading:

India is a country with abundant sunshine. The key to any efcient

building is to work with the sun and factors like orientation and

shading are critical. Orient the building such that the long axis is

north-south to prevent exposure to the heat of the sun. Shading of

the building is a zero cost strategy and can be incorporated in the

design. Shading devices like overhangs, ns, jalli screens have long

been used in our traditional architecture, wit h a good understanding

of the sun.

Results:

Savings with proper orientation: 2.1%

Savings with shading measures: 3.4%

Cost: Zero to Minimal Cost

Strategy 2:Reduce Wall Window Ratio:

The amount and type of glazing in a building is critical to the

energy performance. The balance of bringing in enough daylight

and preventing the ingress of heat requires simulation. To

optimize the area of glass on the building presents a great

method to save energy and money. As glass is approximately

four times more expensive than wall for the same area, initial

costs of the construction can be reduced drastically. Considering

the energy aspects, fenestration should be between 20-40% wall

window ratio (depending on geometry and glass type) to achieve

optimum results. Our climate does not require huge expanses of

glass which bring in heat and glare.

Results:

Saving by reducing the Window Wall Ratio (WWR) from

60% to 40% is 2.6%

Cost: Reduction in Initial Cost

Strategy 3:Can a light color building save?

Yes. Materials with high reectivity and lighted colors reect

heat. Simple use of these materials for walls, roofs, paving

and other components can greatly reduce buildings heat gain.

Strategies like roof coatings, china mosaic tiles on roofs, light

color painted walls or stone surfaces are good examples of this

zero cost strategy.

Results:

Savings by changing from dark to light color: 0.9%

Cost: Zero Additional Cost

Strategy 4:

Glass glass everywhere, but no daylight or views?

This is a common problem seen in so many glass box buildings

today. Too much glass (and incorrect specications) results in too

much heat gain and glare, which results in blinds being closed, and

he whole purpose of the use of glass is lost. Computer simulation

can help in selecting the Correct Glass for the project. Glass has

3 critical properties, namely the amount of natural light (Visible

Light Transmittance), heat conductance (U Value) and shading

(Shading Coefcient) and hence using computer simulation, the

team achieves the balance of heat versus light.

Results:

mproved Glass: Changing the Glass properties from U-Value 5.7

W/m2 K and SC 0.25 to U-Value 1.8 W/m2 K and SC 0.20 brings

3.5% total energy savings. Cost: Increase in initial cost of Glass.

Reduction in capacity of HVAC equipment.

Strategy 5:

Low conductivity materials & insulation:

Insulation is another great way to reduce heat ingress through walls

and roofs. Exterior Walls can be made out of concrete, brick, AAC-Blocks

and other materials. Choosing a material with good thermal insulating

properties does not necessary mean that the construction is more

expensive. In fact if we choose materials like AAC Blocks, not only does

it provide better thermal properties, but it is also lighter in weight and

Results:

This result of2.7% savings was achieved by adding 2 inch polyurethane

insulation on exterior walls and roof, whereby increasing insulation and

reducing heat transfer.

Strategy 6:

Maximizing daylight and reducing articial light:

A building can maximize their use of daylight by turning off

the articial lights when lux levels are sufcient. Daylight

sensors installed along the perimeter of the building achieve

this saving.

High efciency articial lights can also be installed to reduce

the electricity load due to lighting of the building. T5 and LEDs

are good examples of this saving strategy.

Results:

Daylighting sensors are able to save 6% of the total energy

consumption. Reducing the lighting power density by 20% will

earn additional 6% energy savings.

Strategy 7:

Improved HVAC system:

The performance of the HVAC System has a big impact on the

energy consumption. Their strategy in our case is to increasing

the COP of the centrifugal chillers from 5.0 to 5.5, installing

variable speed drives, reducing the pressure losses of the

air-supply system and replacing standard pumps and motors with

higher efcient ones. These parameters not only help to reduce

the loads, but will indirectly offset the costs as power back up DG

sets and transformer capacity would be reduced proportionately.

Results:

Improved HVAC system will have a savings effect of12.5% on the

total energy consumption.

Strategy 8:

On demand HVAC system:

Demand Control Ventilation works by sensing the

CO2 level in the exhaust air and adjusting the fresh

air requirements. The principle is that if a room is

not occupied, then CO2 levels are low, and fresh

air being pumped in is reduced. When occupied,

the system will ensure that the CO2 levels do not

exceed the permissible limits.

Results:

Demand Control Ventilation will save 1.3 % of the

energy used per year.

Strategy 9:

Heat Recovery Wheels:

When conditioned air is exhausted from a space,

fresh air at outside temperature needs to be

cooled / heated before supply to maintain thermal

comfort in the space. The heat recovery wheel

helps to transfer some of the energy, to pre heat /

cool the fresh air before reaching the HVAC system.

Hence a heat recovery wheel could transfer heat

to reduce the temperature of ambient outdoor air

by 6 8 degrees and can save on energy loads of

the HVAC system.

Result:

Installing a heat recovery wheel in this project will

save 1.5 % on energy cost.

Optimized Case:

To implement all mentioned Energy Efciency Measures can reduce the total energy consumption by 36%. It

must be considered that the single EEMs show higher savings in percent as they were simulated individually

based on the basic design. The graphs show that the miscellaneous equipment is always kept at the same

load and at the end this part takes up a huge percentage of the total energy consumption. Additional energy

efcient appliances would be able to save more energy, what is not modelled here.

These strategies to save energy will bring different results for every project, as they depend on various

parameters like orientation, geometry, occupancy, internal loads and HVAC system. To start the energy

simulation process early in the design of the building can assist in making decisions towards a greener

building at a minimal increase in initial capital cost.

With the rising energy costs, not only does this mean greater savings, but also faster paybacks

and adds validity to the statement - Going Green Makes Sense where inspired tobe green energy experts prepared this showcase for you. Please contact them by e-mail at

HVAC Insulation, Green Buildings & LEED: What

Is the Connection?

Leadership in Energy & Environmental Design,

better known as LEED, is generating more

interest then ever among HVAC engineers. In

practice recent studies confirm that if buildings

are designed with GREEN objective in mind, theywill not only earn good LEED ratings but will also

save energy costs in long run with out incurring

much incremental cost. Insulation plays key role

in Green Buildings and its scope in grand scheme

of LEED is identified and may get more

recognition in coming days.

How Insulation Selection Impacts LEED

Certification?

Insulation can contribute to LEED within the 3

categories of Energy & Atmosphere, Materials &

Resources, and Indoor Environment Quality, but

certain specific guidelines apply.

1. Energy & Atmosphere (EA)

2. Materials and Resources (MR)

3. Indoor Environment Quality (IEQ)

Role of Insulation in LEED could increase

Existing LEED programmes continue to evolve, so

guidelines will continue to change based upon

input from committees and Architects / HVAC

fraternity. In coming days there should be greater

emphasis on indoor environmental issues,

including acoustics, mould and low-emitting

materials. All of these have the potential to

expand the importance of insulation selection

within LEED projects, as we don't want LEED

rated Green buildings to become just another

building.

What is GREEN about Class O Armaflex Plus &

Class O Armaflex Closed Cell Insulation &

ArmaSound Super Silence Ductliner?

While LEED may include many credits that are

specific to mechanical insulation, its overall

concern with indoor air quality, emissions,

pollutants, particulates, etc. is pervasive. From

this perspective, Armaflex is, indeed, a very

green product. Consider the following

important points about Armacell products;

Water Vapour Resistance:

Armaflex's closed cell structure inherently

prevents water vapour absorption; eliminating

one main ingredient required for fungal growth,

as well gives long term insulation efficiency.

MICROBAN antimicrobial product protection:

Built into Class O Armaflex Plus. Microban

antimicrobial protection is another layer of

defence against the spread of mould & mildew.

Non-particulating and Fiber-free:

This prevents it from becoming an irritant to

building occupants. So there is less concern about

material in ductwork breaking down and being

released into the air stream.

Formaldehyde Free, Low VOCs, and negligibleoff-gassing makes Armaflex a healthy choice for

facilities concerned with indoor pollutants.

There are reasons why our brand is green...

Green roofs play a most important role in thermal protection of roofs. Roof gardens not only give the building

a green look, they actually make the building more energy efcient.

ELT India Enterprise has brought the latest green roof technology from Canada, which enables green roong of

any existing and new building. For an existing roof a solution can be provided whether it is sloping or at, has

services running, a sky light or other constructions which cannot be removed. The company dedicates hard work

towards the mission of facilitating the integration of environmental technologies such as green roofs and living walls

nto our dwellings and work places.

The lightweight and low maintenance systems can weigh as little as 8 kg/sq.ft when fully saturated, what makes

t perfect for retrots. Designed with sustainability in mind, each component is either recycled or recyclable to

conserve our precious natural resources. ELT Easy Green is the one product which combines all standard green

roof layers in one!

The ELT system can be installed

over any membrane type. However,

single-ply membranes like (EPDM and

TPO) often do not require an additional

root barrier saving on material costs.

Panels are modular with overlap strips

around two sides. They can be stacked up

for shipping and trimmed to t on site. All of

these features translate into faster installation

times and reduced project costs.

The plastic carrier has integrated water

reservoirs and drainage. The water is

stored until saturation in the reservoirs

and then drains down through the

drainage holes and ows to the nearest

drain through the void space below the

system.

The recycled HDPE plastic carrier acts as:

Water reservoir

Drainage layer

Protection from excessive drying of roots

from airspace below

Cups greatly improve product

handling and making it easy to install

The vegetation area has a bio-blanket at the

base which is xed on the drainage board. This

Bio-blanket is made from recycled polyethylene

and renewable hemp bers and performs the

role of a water retention, rainwater lter and

anchor for the roots. It helps to distribute the

water evenly across the vegetation area and

makes water management most efcient.

Local Growing Mediums ELT uses only local

growing medium sources to keep within LEED

guidelines (500 miles to site).

The pre-growing process begins with green roof

panels being laid out at their grow facility. By

pre-growing the panels, the benets are seen

immediately after installation. The established

plants resist weed pressure and reduce irrigation

requirements resulting in maintenance savings.

When fully established, the plants anchor into the

bio-blanket provides a great erosion control.

An irrigation system is installed to help the plants

while they adjust to their new environment during

the rst season. If designed in advance, after the

rst year the irrigation can remain in place as an

inexpensive method of dealing with dry periods,but may not be needed for regular irrigation.

3rd Party Testing: ELT Easy Green green roof systems being tested at the Centre for the Advancement of Green

Roof Technology (BCIT). We have 2 Research Evaluation Modules that can be viewed by the public as well as many

other case studies around the world.

ELT is a proud member of the Canadian Green Building Council and

with our innovative roof system we help to achieve several LEED

credits. The system can contribute to the following, depending on

the individual project and design of green roof:

1 point Reduced site Disturbance, Protect or Restore Open Space

2 points Stormwater Management, Rate, Quantity and Treatment

1 point Landscape and Exterior Design to Reduce Heat Islands

2 points Water Efcient Landscaping

1 point Innovative Wastewater Technologies

2 points Optimized Energy Performance

2 points Recycled Content

2 points Local/Regional Materials

1-4 points Innovation in Design

To implement a green roof in the design of a building, helps to save cooling energy because the green roof acts

as an insulation layer which does not allow heat to be conducted to the space. This green area can also serve

as a recreational space for occupants and it brings back our mother nature into urban lifestyle.

ELT India is the single source for all your green

roong needs of design, manufacturing components,

growing, installation and maintenance. For more information

BUILD WITH HEMP and SAVE ENERGY

We all wish that we could use materials which can be environmentally friendly

produced, without using to much energy and creating green house gases. This

innovative material helps to store CO2 emissions, saves energy over the buildings

lifetime and comes with all the features of a strong building material.

Hemcrete is an established walling

material for carbon negative highly

thermally efcient walls. While hemp is

growing it is absorbing CO2 from the air

and produces oxygen after cutting and

manufacturing the Hemp to wall blocks

the CO2 is still stored in the material

what results in a negative CO2 balance

of the material. This building material

offers all the advantages of a strong

and long lasting construction material

and comes with all the green features

you could possibly expect from building

material:

high insulating properties

vapour permeable

air tight

lightweight

from renewable materials

It can be used for all kinds of building applications from roof insulation to wall construction to ooring.

It is seven times stronger than concrete, weighs half as much, is waterproof, reproof and at the end

of its lifecycle it is completely recyclable.

In the U.K this amazing green material is used for years. To grow hemp is illegal in some countries but

in England a lot of farmers earn their money with growing hemp as a raw material for that amazing

building material. The hemp plant is growing without use of fert ilizer and with little water needs.

same size would have generated up to 600 tonnes of

CO2 emissions. By using Tradical Hemcrete, the

Adnams distribution centre has therefore made a

potential saving of up to 750 tonnes of CO2.

The commitment of Lime Technology is to work

with a variety of speciers, contractors, developers

and research bodies across all market sectors. It

is the aim to create buildings that have both a low

embodied CO2 footprint as well as being low energy

in use. They are working on the forefront of creating a

new wave of low carbon products to build tomorrows

buildings today.

The U values for walls depend on the

Hemcrete wall thickness for example

for standard mix:

a 200 mm wall has a U value of

0.3 W/m2 K

Chilled BeamsA new cooling system nds the way to green buildings

A lot of inventions were made to cool buildings down to comfortable

air temperatures, always with the goal of increasing the efciency and

adapting to different situations. Chilled beams can denitely help to

make the process of cooling more efcient and reach the target of an

energy conserving building.

The chilled beam system makes use of the natural air ow and works with

buoyancy. Chilled beams are pipes circulated with cold water, they are

mounted on the ceiling and provide a cold surface which is exchanging

the temperature by convection and radiation directly to the room air. The

greatest advantages of these systems are the huge savings in ventilation

energy as compared to a conventional system where the air serves as

a medium to transport cold air to the room. The new sustainable sky

scrapper pearl river tower will make use of this technology. ( Picture on

the right)

Conventional buildings as well as Green buildings using most of their energy for operation of its cooling

system. These systems require a lot of energy for supplying the cold air through air ducts into the room. In

many cases ventilation energy takes up the biggest share of the energy cost for cooling. To reduce this share

chilled beams are introduced to green buildings.

Air with its low density is not predestined to transport energy. One cubic meter of air can store around 1 kJ if

the temperature changes by one degree Celsius, for the same volume (1 sqm) water is able to store 4000 kJ of

energy. What means to extract 4000 kJ of load from a space will require either 40,00,000 litre of air or just

1,000 litre of water.

The innovation of chilled beams is that the loads are removed with the help of water and not in the conventional

way with air. These systems were rst introduced in Europe as chilled ceilings, where water pipes as part of the

ceiling work with convection to cool down the space. The disadvantage of limited cooling capacity was taken

care of by changing the system to passive chilled beams. This concept uses pipes and coils which are installed

on the ceiling so that the air can ow through it and cool down. Problems of condensation on the ceiling were

faced in some projects due to the low temperatures on the surface of the chilled beam and the sometimes high

humidity of fresh air.

Active chilled beams are developed on the basis of passive

chilled beams with the target of a higher capacity and a

controlled fresh air supply. The primary air from the air

handling system is introduced to the active chilled beam

through high velocity nozzles, and this starts of a chain

reaction: The supplied warm air cools down on the beam,

gets heavier (as the density of air increases with falling

temperature) and sinks down to the oor. Indoor air heated

up by all internal loads ows up to the chilled beam (as

hot air rises) and is getting cooled again by the cold water

circulated pipes. Due to forced convection, active chilled

beams achieve cooling densities about twice of those of

passive chilled beams.

Advantages of chilled beams are the reduced material and

installation costs and the increased energy efciency of the

HVAC system. High comfort through excellent air movement

and uniform air temperatures throughout the room alongwith very low noise levels can be a reason to go for active

chilled beams. In some cases space savings in the ceiling

plenums can be achieved by implementing this technology.

Condensation control is one challenge faced by working

with chilled beams. The humidity of the supply air must

be analyzed carefully and appropriate ways should be

adopted to avoid the condensation on the ceiling. To

make sure that condensation does not occur, the wetbulb

temperature of the supply air must always be higher than

the supply water temperature of the chilled beam. For humid

climates a dehumidication of the air will be necessary

before supplying it to the room. Attention should be paid

to airtight construction of the building what will inuence

the inltration of (humid) air. Chilled beams are well suited

for applications where heat generated by equipment drives

cooling loads and supply airow levels. For buildings with

high indoor latent loads, such as restaurants, health clubs or

theatres other systems may be a better choice.

Manufacturers are now offering multi-purpose chilled beam

units. These are single units that include light xtures,

sprinklers, cooling coils and the chilled beams. Combining all

of these el ements into one unit offers simplied installation

and gives more importance to the design.

Advantages of Chilled Beams

Very low noise levels.

Reduced cost of air ducts and supply fans.

Less ductwork.

Supply water temperature can be signicantly

higher.

System does not take up much space and can

even t in to ceilings.

No moving parts = l ess maintenance.

Saving energy of delivering sensible cooling to

the space.

Chilled beams can save 15-20% of the cooling energy or more, reason being that the sensible cooling takes place directly

to the space and the ventilation energy is reduced signicantly as only the required amount of fresh air is supplied to

the room. Higher chilled water temperatures around 60 degree Fahrenheit for chilled beams and 44 degree Fahrenheit

for conventional systems make high savings in cooling energy possible and reduce the electricity bills.

Buildings consume vast amounts of our resources like water, energy, materials and threaten

the ecological systems that support life, from the ozone layer to the worlds forests.

Therefore,there is a need to rethink ... Reassess our excess as it is important to build for fullling

our needs and not the greed.

``Green Interiors can be achieved by both simple & high tech ways, initial

capital cost is a bit more but human capital that occupies, is the supreme

cost of any facility.
