The main goal was to evaluate the technical and financial feasibility for a social housing company to transform the existing stock into a very energy efficient housing park. The standard procurement procedure was followed.
An architect was selected to do the design, and a market request was published in order to select a contractor. Extra funding was foreseen to cover the extra costs. A follow-up phase is foreseen, with monitoring and education of the inhabitants on how to live in the houses.
Why was the building selected for renovation? The buildings needed to be renovated anyway. The orientation of the selected 5 row houses was ‘ideal’: north-south.
