BELGIUM – Single-family house from the 80s
This single-family house is a terraced house built in 1982 and owned by a social housing company. A centralised condensing gas boiler is installed to provide space heating and domestic hot water, but the building has no ventilation system or cooling system. Since a lot of similar dwellings were constructed at the same time in the neighbourhood, a renovation concept is being developed to renovate the whole district. For the original, non-renovated state of the building, measurements are available of the indoor temperature and the total yearly energy demand.
