Abstract [en]
The European building stock was renewed at a rapid pace during the period 1950–1975.In many European countries, the building stock from this time needs to be renovated, and thereare opportunities to introduce energy efficiency measures in the renovation process. Informationavailability and increasingly available analysis tools make it possible to assess the impact of policyand regulation. This article describes methods developed for analyzing investments in renovationand energy performance based on building ownership and inhabitant socio-economic informationdeveloped for Swedish authorities, to be used for the Swedish national renovations strategy in2019. This was done by analyzing measured energy usage and renovation investments made duringthe last 30 years, coupled with building specific official information of buildings and resident areacharacteristics, for multi-family dwellings in Gothenburg (N = 6319). The statistical analyses showthat more costly renovations lead to decreasing energy usage for heating, but buildings that havebeen renovated during the last decades have a higher energy usage when accounting for currentheating system, ownership, and resident socio-economic background. It is appropriate to includean affordability aspect in larger renovation projects since economically disadvantaged groups areover-represented in buildings with poorer energy performance.
