Application: market environment.
Renewables system technology for residential new build.
- the housing market is under considerable pressure in some regions due to lack of space
- strong growth in the apartment block segment (4–10 units)
- statutory frameworks dictate the use of heat generators that utilize renewables

Application: project.
Renewables system technology for residential new build.
A new build in the residential sector.
The apartment block will comprise six residential units. Heat generators utilizing renewables will be installed in order to comply with the EnEv. Proprietors will receive state or regional subsidies depending on the building project’s efficiency standard.

Application: requirements.

Logavent HRV156 K heat recovery ventilation unit
System benefit:
The level of insulation can be increased in order to benefit from additional subsidies. This in turn increases the level of air tightness and minimizes the air change rate through the building envelope. The air change rate is important for both building and occupants alike. As a result, it is recommended that the standard system be supplemented with a highly efficient heat recovery ventilation unit to ensure automatic air exchange and a comfortable indoor climate.
