Project Summary


Social housing association Breburg realised 87 m2 collective solar thermal system on the roofs of an apartment buildings complex which is split in two blocks: the Burgemeester Visserstreet (40 apartments, 8 floors) and Scoutbackstreet (20 apartments, 4 floors). The system is placed as part of an overall renovation of the building. Small individual gas-fired kitchen tap water heaters that emitted exhaust gases into the dwellings have been replaced by a central solar hot water system and the ventilation system has been improved. Furthermore the mostly senior tenants were offered freedom of choice between several packages for renovation of the bathroom, kitchen and toilet. The realisation of this system fits in Breburg’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:

"Studying the feasibility of renewable energy options is a standard procedure in renovation projects for WonenBreburg. In our experience the solar renovation of the hot water systems leads to higher comfort and better indoor climate without raising the housing costs."
