Case Study Multi-family house
This case study demonstrates the complete calculation of the energy performance of an entire multi-family building with 16 apartments and the related technical systems using the (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 building and technical systems and that the needed modules are available.
This check is repeated for three typical buildings in three separate case studies. This case study is about a multi-family house.
Two base cases have been selected:
- an existing Multi-family house (MFH), typically 20 to 30 years old that has not yet undergone a deep renovation;
- a new building.
A comparison has been done with the calculation per zone. The global result for the needs is similar but there are sensible differences between apartments, as it can be expected due to orientation (south versus north) and positioning of flats (ground floor, intermediate floor and last floor). This is relevant in connection with the use of energy performance calculation for Energy Performance Certificates.
