Project Summary

Description

Social housing association WonenBreburg realised a 247 m2 collective solar thermal system distributed on the roofs of the Landse Akkers building with a total of 144 dwellings. The system is placed as part of an overall renovation of the complex, including the hot water system and mechanical ventilation. Small individual gas-fired kitchen tap water heaters that emitted exhaust gases into the dwellings have been replaced by a central solar hot water system.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:

"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."
