The measure was carried out for an apartment block built in 1974. The heating system was renewed in 2008 and the windows replaced. However, due to the age of the building, major maintenance work was still required. The roof and the façade had been damaged and need reinstating.
The measures recommended for these buildings were roof, external wall and basement ceiling insulation. After two internal rounds of decision making the owners decided to decide to install top floor and the basement ceiling insulation.
