REHVA Seminar March 17, 2011, HVAC in zero energy buildings


Towards nZEB:• Roadmap of some

countries towards nearly zero energy buildings to improve energy performance of new buildings

• Many countries have prepared long term roadmaps with detailed targets

• Helps industry to prepare/commit to the targets


• EPBD recast requires nearly zero energy buildings, but does not give minimum or maximum harmonized requirements

• It will be up to the Member States to define what nZEB for them exactly constitute

• In the definition local conditions can be obviously taken into account, but the uniform methodology can be used in all Member States

REHVA nZEB Task Force:• Proposes a technical definition for nearly zero energy buildings • Provides energy calculation framework and system boundaries

associated with the definition to specify which energy flows in which way are taken into account in the energy performance assessment

• The intention of the Task Force is to help the experts in the Member States in defining the nearly zero energy buildings in a uniform way

Why nZEB definition is needed?


EPBD recast – major changesArticle 9 Nearly zero energy buildings

- By 31 Dec 2020, all new buildings are nearly zero energy buildings- After 31 Dec 2018, public authorities that occupy and own a new building

shall ensure that the building is a nearly zero energy building

Articles 4 & 5 Setting of energy performance requirements- Setting of minimum energy performance requirements based on calculation

of cost-optimal levels with the methodology referred to in Article 3. - The calculation of cost-optimal levels shall be performed in accordance with

the methodology developed by the Commission (so called comparative methodology Annex III)

- Primary energy target values have to be set in kWh/m2

- The Commission shall establish by 30 June 2011 a comparative methodology framework

http://eur-lex.europa.eu/JOHtml.do?uri=OJ%3AL%3A2010%3A153%3ASM%3AEN%3AHTMLThe laws and regulations shall be adopted and published in Member States by 9 July 2012.

http://eur-lex.europa.eu/JOHtml.do?uri=OJ:L:2010:153:SM:EN:HTML�


EPBD recast – Nearly zero energy buildings

• In the directive ‘nearly zero-energy building’ means a building that has a very high energy performance. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby.

• Since the Commission does not give minimum or maximum harmonized requirements, it will be up to the Member States to define what for them exactly constitutes a "very high energy performance“

Net zero energy buildings in practice

What nZEB means in practice?• Energy demand/delivered energy use is reduced as much as reasonable

achievable (insulation, heat recovery, heat pumps etc.)• On site renewable energy production, most commonly solar PV and thermal,

district heat from renewables and renewable fuels also accounted• Annual balance of delivered and exported primary energy = 0• Typically a grid connected building exporting energy in summer, using

delivered energy in winter

Luukku house: Finnish net plus energy building in Solar Decathlon 2010 competition in Madrid


To define nZEB it was needed

In order to propose a general definition, it was needed to clarify:• which energy flows shall be included – ALL• the use of primary energy factors for primary energy indicator • system boundary definition with inclusion of active solar and wind• the technical meaning of “nearby” in EPBD recast so that it may mean

existing district heating or cooling network or any other technical system serving a group of buildings

• Energy performance definition of EPBD recast was followed so that appliances (households and outlets) were included, i.e. all energy used in buildings would be accounted.

• For the system boundary definition, a general form modified from the one of EN 15603:2008 is proposed.


REHVA Task Force “Nearly Zero Energy Buildings” nZEB proposed definitionsnet zero energy building (nZEB)energy use of 0 kWh/(m2 a) primary energy

NOTE 1 A nZEB is typically a grid connected building with very high energy performance. nZEBbalances its primary energy use so that the primary energy feed-in to the grid or other energy network equals to the primary energy delivered to nZEB from energy networks. Annual balance of 0 kWh/(m2 a) primary energy use typically leads to the situation where significant amount of the on-site energy generation will be exchanged with the grid. Therefore a nZEB produces energy when conditions are suitable, and uses delivered energy during rest of the time.

nearly net zero energy building (nnZEB)national cost optimal energy use of > 0 kWh/(m2 a) primary energy

NOTE 1 The Commission shall establish by 30 June 2011 a comparative methodology framework for calculation of cost-optimal levels (EPBD recast).

nZEB has exact performance level of 0 kWh/(m2 a) primary energy use

nnZEB depends on national conditions

System boundary for nearly net zero energy building definition, connecting a building to energy networks. Net delivered energy is delivered Edel,i minus exported energy Eexp,i accounted separately for each energy carrier i. Primary energy E is calculated with primary energy factors fi (simplified equation with the same factors for delivered and exported energy carriers)


Primary energy: total or non-renewable?Many countries have adopted in their regulations PRIMARY ENERGY and NON-RENEWABLE primary energy factors (e.g. 1.1 for oil and 0.2 for wood)

EPBD recast defines primary energy as: ”energy from renewable and non-renewable sources which has not undergone any conversion or transformation process”

⇒ TOTAL primary energy and TOTAL primary energy factors shall be used according to EPBD (meaning that there is no difference between bio or fossil fuel and the factor always exceeds unity)

Another detail are primary energy factors for delivered and exported energy carriers, which may or may not be equal, depending on national definition, i.e. both equations can be used:

nZEB – detailed system boundary

Energy boundary of net delivered energy. The box of “Energy need” refers to rooms in a building and both system boundary lines may be interpreted as the building site boundary.


Example – Low energy house

Low energy detached house

Net energy needs:• 48.0 kWh/(m2 a) net energy need for heating (including ventilation and DHW)• 10.7 kWh/(m2 a) net energy need for cooling• 7.0 kWh/(m2 a) electricity for lighting • 16.0 kWh/(m2 a) electricity for appliances

• solar thermal provides 14.0 kWh/(m2 a) domestic hot water• the rest of heating need is supplied with ground source heat pump

system, which has the seasonal performance factor of 3.2.

• On site thermal energy 14.0 kWh/(m2 a) is reduced from the net energy need of 48.0 kWh/(m2 a). Heat pump produces 34.0 kWh/(m2 a) thermal energy with electrical energy input of 10.6 kWh/(m2 a).

• There is no exported energy. Primary energy is 101 kWh/(m2 a)


Example – nnZEB Office building

• a gas boiler for heating with seasonal efficiency of 90%• free cooling from boreholes (about 1/3 of the need) is used and the

rest is covered with mechanical cooling• for borehole cooling, seasonal energy efficiency ratio of 10 is used

and for mechanical cooling 3.5• Ventilation system with specific fan power of 1.2 kW/(m3/s) will use

5.6 kWh/(m2 a) fan energy.

• a solar PV system providing 15.0 kWh/(m2 a), from which 6.0 is utilized in the building and 9.0 is exported to the grid.

energy is 66 kWh/(m2 a)


ConclusionsGeneral definition format is proposed to clarify the exact technical meaning of EPBD recast requirements in order to support national implementation

It is proposed to the Member States to use the system boundary shown in Figure 4 and primary energy definition given by Equation 1 in defining the performance levels of nearly net zero energy buildings. (refers to REHVA J)

Net zero energy requirement has exact performance level of 0 kWh/(m2 a) primary energy use. The performance level of “nearly” net zero energy use depends on national conditions. The following definitions were proposed:net zero energy building (nZEB)energy use of 0 kWh/(m2 a) primary energynearly net zero energy building (nnZEB)national cost optimal energy use of > 0 kWh/(m2 a) primary energy

The proposal is to be published in REHVA Journal 2011/3 May issue.

http://ec.europa.eu/energy/efficiency/action_plan

• Background: EU will achieve only half of 20-20-20 targets by 2020 if it continues current policy and actions

• Some new actions:• Exemplary role of the public sector• Accelerate the refurbishment rate of the building stock• Public authorities should be required to refurbish at least 3% of their

buildings each year• Energy efficiency criteria to be included in public procurement• Improve the energy performance of appliances• Improve the efficiency of power and heat generation• More smart grids and smart meters

• http://ec europa eu/energy/efficiency/action plan


Important energy related directives in the European CommissionBuilding performance – EPBD – 2002, Recast 2010

Improvement of energy performance of buildings

End use efficiency and energy services -ESDMember States to save at least an additional 1% of their final energy consumption each year for the 9 years- second set of intermediate reports due in June 2011

Energy using products – EuP 2005 Energy related product ErP 2009

Aim at protecting the environment and securing energy supply

Renewable energies – April 2009Increase the use of renewables up to 20%, bio fuels up to 10%


EPBD recast - 2010

• More demanding than EPBD 2002 version

• Not so stringent, but more realistic than the proposal by the Parliament in 2009

• Published in July 2010 – time for national legislation only 2 years


Major changes in EPBD (1)• Reference to CEN standards• National cost optimised solutions

– Guidelines under preparation

• Primary energy target values have to be set in kWh/m²• The 1000 m² limit removed from articles dealing with

renovation of existing and new building RES etc. • Regulations for new buildings to apply in major

renovations with some limitations


Major changes in EPBD (2)• Specific regulations requested also for technical

systems – existing compulsory, new buildings optional

• All new buildings have to be “nearly zero energy buildings” in 2020, public sector in 2018

– REHVA assists in uniforming the definitions

• Measures needed to overcome market barriers are requested

• Stronger and more meaningful position for energy certificates


Major changes in EPBD (3)• From boiler inspections to heating system

inspections• In A/C inspections more emphasis is put on

reducing cooling loads– REHVA Guide under preparation

• Independent controls system for all national inspections

• RES and ErP directives to be taken in account in EPBD regulations


Methodology to calculate cost-optimal level of energy performance regulations

• MS and stakeholders workshop on March 16th (20 + 60 participants)

• Guidelines for MS – to be published in July 2011

• Implementation in MS by 2013• Net present value method based on EN

Items discussed in WS March 16th

• Definition and use of the reference buildings (new, exsiting, building types etc.)

• Whose cost optimal? (private/societal)• Estimated escalation rate of energy (oil, gas,

coal on EU level, rest on natoinal level)• Expected economic lifecycle (30 years?)


Directive on the promotion of the use of energy fromrenewable sources (Adopted in April 2009)

• electricity, heating, cooling and transport• a 20% target for the overall share of

energy from renewable sources and• a 10% target for renewable energy in

transport


Renewable sources defined as• Active solar• Hydro• Biomass (boilers or

co-generation) with min fuel efficiency >0.8

• Wind• Geothermal• Heat sources of heat

pumps – COP > 2.88 (air, water, ground)

Not included in renewable energies to avoid double counting:• Improvements in

energy efficiency• Passive solar

First experience

Construction phase: supervision of execution is highly important

Ventilation: installation and commissioning is decisive to reach target efficiency

Calculation of Net Zero Energy Building (nZEB) level accordingly to EPBD, EnEV in this case, shows difference to reality

Net Zero Energy Building (nZEB) concept requires good calculation methodology in order to reach net zero energy level in reality

Building is occupied since 1st of November 2010

=> We are on track but not yet economically feasible.Our target is to learn in phase 1 about how to come to economically feasible solutions for net Zero Energy Buildings which reach to zero in reality, only real nZEB will contribute to achieve EU 20-20-20 targets.

Sorption Rotors (HX1 and HM1)

• Active coating on the sorption foil for sensible and high humidity recovery

• The humidity transfer of the sorption rotors is a physisorption process on a very high active surface.

• There is no chemical process, the catch of molecules is based on Molecule size and weak atomic forces

Sorption material , Silicagel HX1

• Commonly used material in packing and drying applications, SiO2

• 1g adsorbent equal to approx. 700 m2,

We use silica gel 15 g/m2 aluminum 1m² surface = 1.5 football fields

• Extreme high humidity efficiency, especially at high RH level

• Wide distribution of pore sizes

• Is not selective on what it adsorbs

tetrahedras of (AlO4) and (SiO4)(source: Grace website)

(source: Grace website)

• Functional group of materials• Widely used adsorbent in chemical

industry.• Engineered structures to specific

function, pore size defined• In HVAC applications use 3-10Å

pore sizes for water (2.7Å )• We use (AlO4) and (SiO4), 3Å• High humidity efficiency• Very selective to adsorb only

water molecules

Cooling capacity saving 13.4kW / m3/s air. (20.8 if condensing rotor not used in Summer)

Increase of power consumption due to pressure drop increase 0.2 kW/m3/s air

Pay back timeThe investment cost of additional cooling capacity is about 100-200 Euro/kW

>>> The capacity savings due Sorption's rotor was 13 kW/ m3/sgiving investment savings of 1300-2600 Euro/m3/s

Additional investment for Sorption treatment is 400-800 Euro/ m3/s

With 400-800 Euro investment 1300-2600 Euro savings =

0 days pay back time

There is no additional investment from the system perspective. To compensate the energy cost of the pressure drop increase we need 3-5% cooling full capacity utilization or total utilization time of AHU or 5- 10 years of AHU without any use of cooling capacity.

Where to use sorption technology

Installations where cooling is required Regions where peak load management is a topic

(capacity shortage of installed power from utilities)

Chilled beam, chilled ceiling , dry cooling fan coils

applications

Whenever humidification of supply air is required

Existing installation where chillers capacity is limited

and causing problems in summer time

Thank you for your interest!

Questions?

When not to use sorption technology

When there is no cooling used in Summer time– Humidity recovery works only, if exhaust air is cooler and drier

than supply air. i.e. when supply air is cooled

Occasional concerns with Sorption rotors

• Odour carry over

• Bacteria / germ growths

• life cycle expectancy

• Use of molecular sieve recommended

• Antimicrobial agent being used, Hg ions

• Washed rotor reaches same capacity as before

Production quality

• in-house coating machine– entire process control

• Raw materials for coating carefullyselected

• Eurovent certified products

Advantages with sorption rotors1. Lower cooling capacity for AHU´s

– Dehumidify the supply air before cooling coil• 20-50% of cooling capacity in AHU process is dehumidification.

– Smaller cooling equipment and cooling installations.2. Energy saving in summer conditions

– Use of energy recovery in summer time would be motivated

3. Higher humidity recovery in winter time– Better indoor climate – Less humidification needed

Rotor Materials

• Non hydroscopic rotors- Standard aluminium (alloy 1200) (ST1)

- Epoxy coated aluminium (STC1)

- Sea water resistant aluminium alloy 5052 (AK1)

• Hygroscopic rotor, hygroscopic aluminium (STE1)

• Sorption rotors, Siligagel, (HX1)
