Project Summary

Description

Social housing association WonenBreburg realised a 82 m2 collective solar thermal system on the roof of one of their apartment buildings with 6 floors and 95 dwellings. The system is placed as part of an overall renovation of the building, including the façade, entrance, bathrooms and toilets and the hot water system. Small individual gas-fired kitchen tap water heaters that emitted exhaust gases into the dwellings have been replaced by a central solar hot water system. The realisation of this system fits in WonenBreburg’s policies and in the energy covenant agreements closed between the social housing associations in Tilburg and the municipality.

W. van Koert, manager new construction/refurbishment:

"In our experience the ‘solar renovation’ of hot water systems leads to higher comfort and better indoor climate without raising the overall housing costs for our tenants. In this way we maintain and improve the property value of our building stock."
