The set of CEN-EPBD standards consists of 43 titles or parts and can be grouped as follows:
The building physics standards, e.g. describing the calculation of heat transfer by transmission and ventilation, load and summer temperature, solar transmittance and the calculation of the energy need for heating and cooling of the building.
In the second group there are standards on the description and properties (classification) of ventilation systems plus cooling and air conditioning systems.
The third group is focussing on the description of space heating and domestic hot water systems:
- The generation efficiency.
- The emission efficiency.
- Domestic hot water systems.
- Low temperature heating and cooling systems integrated in building elements (embedded systems).
A series of supporting standards on:
- Lighting systems for buildings (including the effect of daylight)
- Controls and automation for building services
- Classification of the indoor environment
- Financial economic evaluation of sustainable energy applications.
A set of standards on inspection:
- Boilers and heating systems
- Cooling- and AC systems
- Ventilation systems.
And, last but not least, the two key standards on expressing energy performance and for energy certification of buildings, the overall energy use, primary energy and CO2 emissions, the assessment of energy use and definition of energy performance ratings.
