The QUB/e method is a dynamic measurement method developed to estimate the whole heat loss coefficient and local U-values of a building in a single night without occupancy. The ability of the method to provide reliable results was demonstrated experimentally in a climate chamber with controlled conditions in a previous work. This paper presents the findings from a series of in situ measurements carried out in a circa 1960s multi-family housing located in Stockholm area (Sweden). The U-values estimated with the QUB/e method were in good agreement with the quasi steady-state (ISO 9869-1) values (i.e., the relative differences were within the uncertainty bound of the measurement methods). It was thus demonstrated that the QUB/e method can deliver a good estimation of the thermal performance of building fabrics within just one night, significantly less than the 2–4 week period required for quasi steady-state methods.

The author would like to thank Mika Hakosalo, Jan-Ulric Sjögren (Stockholms stad) and Harry Matero (Stockholmshem) for allowing us to perform these measurements in Årsta. The help of colleagues at Saint-Gobain (Tomas Pühringer, Theo Kiriakou, Andrea Mazzucco and Jean-Benoît Racaud) is also greatly appreciated.
