PROVISIONaL DeFINItION OF a NeaRLy ZeRO-eNeRGy BuILDING
A ‘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 signi cant extent by energy from renewable sources, including energy from renewable sources produced on site or nearby.
The energy performance of a building shall be determined on the basis of the calculated or actual annual energy that is consumed in order to meet the different needs associated with its typical use and shall re ect the heating energy needs and cooling energy needs (energy needed to avoid overheating) to maintain the envis- aged temperature conditions of the building, and domestic hot water needs.
The energy performance of a building shall be expressed in a transparent manner and shall include an energy performance indicator and a numeric indicator of primary energy use, based on primary energy factors per energy carrier, which may be based on national or regional annual weighted averages or a speci c value for on-site production.
The methodology for calculating the energy performance of buildings should take into account at least the following aspects: – the following actual thermal characteristics of the building including its internal partitions: thermal capacity, insulation, passive heating, cooling elements and thermal bridges;
– the heating installation and hot water supply, including
their insulation characteristics;
– air-conditioning installations;
– natural and mechanical ventilation which may include airtightness;
– built-in lighting installation;

– the design, positioning and orientation of the building, including outdoor climate;
– passive solar systems and solar protection;
– indoor climatic conditions, including the designed indoor climate; – internal loads.
The positive in uence of the following aspects shall, where relevant in the calculation, be taken into account:
– local solar exposure conditions, active solar systems and other heating and electricity systems based on energy from renewable sources;
– electricity produced by cogeneration;
– district or block heating and cooling systems;
– natural lighting.
INteRPRetatION OF tHe PROVISIONaL DeFINItION
No account is taken of the following energy ows:
–The power consumption of ICT equipment and the air condi- tioning of ICT rooms (energy demand dependent on the level of activity in the building).The power consumption related to such equipment is not included in the building’s energy balance. Never- theless, the internal loads of ICT equipment in of ces and meeting rooms are included in the building’s energy balance.
–The electricity and gas consumption of kitchen equipment (including dishwashers) and the kitchen’s air conditioning (energy demand dependent on the level of activity in the building).The internal loads related to such equipment are not included in the building’s energy balance.
– Non-domestic hot water.
– Air conditioning and arti cial lighting in the gallery during events.
