摘要

In this paper the findings from a long-term field study of the thermal performance of a circa 1950s ing are presented and discussed. The study aimed at evaluating the robustness of the QUB method field under UK climatic conditions. A series of 147 QUB tests were performed during the whole period (September 2016 - March 2017) in a detached house located in the University Park University of Nottingham considering two distinct conditions: as-built and with increased airtightness.The QUB method was able to provide consistent and robust estimates of the Heat Transfer Coefficient (HTC) of the whole dwelling with approximately 80% of the results within 10% from the mean and than 95% of the results within +/- 15%. The need to treat heat losses occurring through the ground assessing the thermal performance of buildings through experimental diagnostics methods was lighted, especially in uninsulated concrete slab floors. The method devised to isolate the ground floor losses from the whole building losses resulted in reduced dispersion of the adjusted Heat Coefficient with a coefficient of variation of 5% and 98% of results within +/- 10% from the mean.
