Abstract

This paper presents an innovative and simple method for the experimental measurement of the total heat loss coefficient of a building envelope, and its validation. The heat loss coefficient being the sum of the real U-Value of the house and its infiltration losses, this method is called QUB (Quick U-value of Buildings). It only uses the temperature responses to two different constant power excitations, done during two consecutive nights of experiments, which makes it possible to do a complete test in about 48 hours. While the experimental heat loss coefficient cannot be used for energy consumption prediction, it can be used to assess the quality of the construction by comparing it to calculated values or to previous measurements, for instance done before improvements. QUB is validated by comparing its results to those obtained in a unique facility where steady-state can be reached experimentally: the Energy House, developed by the University of Salford, built inside a chamber whose temperature can be regulated. Steady-state and QUB values of the total heat loss coefficient are compared, showing very good agreement between both methods.
