Buildings performance indicators to prioritise multi-family housing renovations

Paying attention to the constructed city and renovating buildings are two objectives of current European policies. This article develops a system of physical performance indicators to detect multi-family housing estates that perform worse in energy efficiency, airborne sound insulation against outside noise and accessibility terms. Indicators were developed in close cooperation with the local Administration for residential estates and on a district scale, and allowed the buildings in worse conditions to be detected. The results are graphically represented on urban plans. Indicators are presented by a case study of social housing states in the city of Zaragoza for the 1939-1979 period.
