Case Study – Single family house
This case study demonstrates the complete calculation of the energy performance of a building and the related technical systems using the set of (CEN and ISO) EPB standards. The objective is to demonstrate that the connections between modules work so that it is possible to perform a complete energy performance calculation with the set of EPB standards. Some variants are also tested to cover the most likely cases coherently with the type of building. This is to check that the system works not only for a single case but for foreseeable configurations of buildings and technical systems and that the needed modules are available.
Two base cases have been selected:
- an existing single-family house (SFH), typically 20 to 30 years old that has not yet undergone a deep renovation;
- a new SFH building.
The energy performance of the existing building has been calculated at first for three typical climates, taking into account a building envelope insulation level in accordance with the climate. The basic system configuration is the same for all three climates: radiators, condensing boiler, domestic hot water production with storage, natural ventilation, no cooling system.
