A 1988 prefabricated apartment block, renovated in 2016 with external insulation, new windows, heat pumps and rooftop solar PV, allowing it to disconnect from district heating. Energy savings reached 74%.

Building envelope and structure

Prefabricated reinforced concrete system built with masonry infill that was over clad with an ETICS system and combined with roof and basement insulation. All external windows and doors were replaced.

Heating and energy
