Minimum requirements for energy performance must be followed in the case of new building and buildings undergoing to major renovation. When designing a building, the compliance of the building with the minimum requirements for energy performance is assessed on the basis of the building’s building design documentation.
The minimum requirements for energy performance are established in respect of the building as a whole. For the purposes of calculating the energy performance indicator, in addition to the envelope of the building and its utility systems, the local energy generation systems (such as solar collectors and panels, wind turbines, combined heat and power producers) which are located within the building or on the building site and which feed into the building are regarded as constituent elements of the building. Utility systems (such as district heating) which are connected to an energy network, up to the connection point to the energy network, are regarded as constituent elements of the building.
Minimum requirements of the energy performance of buildings must be proved by issued energy performance certificate.
Minimum requirements for energy performance are set for:
1. small residential buildings
2. multi-apartment buildings
3. office buildings, libraries and research buildings
4. business buildings
5. public buildings
6. commerce buildings and terminals
7. educational buildings
8. pre-school institutions for children
9. healthcare buildings
Arton Energy uses dynamic simulation software such as IDA Indoor Climate and Energy or IDA-ICE to prove minimum requirements of buildings.
