Abstract

Designing building energy performance with confidencerequires accurate information on the properties ofbuilding materials and on assemblies of these materials.However, thermal properties of the building in use arerarely compared to manufacturers’ specifications. Theapproach reported in this paper determines buildingthermal properties using simulations of dynamic heatingtests. It replaces the need for physical tests with the actualbuildings, by conducting these tests with calibratedsimulation models using data from energy performancemonitoring of that building during its normal operation.The resultant method represents a tool for establishingphysics properties of buildings in use before and afterretrofit, and facilitates quality control of retrofit projects.The results pinpoint major discrepancies betweentheoretical and actual thermal properties before and afterthe retrofit, giving practical guidance for safety marginsin relation to technical specifications of building materialproperties and re-evaluation of corresponding technicalspecifications
