Abstract Methods for building envelope inspection are well known since 70's. However, measurement instruments and software improve, making methods for building envelope inspection susceptible to further improvements. In particular, the present paper deals with building envelope assessments performed via heat flux meters and reports the outcomes of a monitoring campaign verifying a measurement procedure proposed by the authors. Such a procedure is aimed at the improvement of the accuracy and reliability in the on-field measurement of the U-value of building constructions. In detail, the proposed method exploits an experimental device providing controlled local heating aimed at speeding up the measurement process and limiting temperature fluctuations, with possible improvements over the calculation of the final U-value. The advantages and limits of this measurement procedure are explained in this paper, together with possible future improvements.

Abstract

Abstract Methods for building envelope inspection are well known since 70's. However, measurement instruments and software improve, making methods for building envelope inspection susceptible to further improvements. In particular, the present paper deals with building envelope assessments performed via heat flux meters and reports the outcomes of a monitoring campaign verifying a measurement procedure proposed by the authors. Such a procedure is aimed at the improvement of the accuracy and reliability in the on-field measurement of the U-value of building constructions. In detail, the proposed method exploits an experimental device providing controlled local heating aimed at speeding up the measurement process and limiting temperature fluctuations, with possible improvements over the calculation of the final U-value. The advantages and limits of this measurement procedure are explained in this paper, together with possible future improvements.
