Infrared-thermography based thermal analysis of the old vs. New type of the non-residential building construction at the identical geo-location and orientation

Abstract

IRT methodology was used in this research in order to provide critical review on thermal behavior of two non-residential buildings constructions at the same geo-location and orientation. Faculty of Agriculture (University of Belgrade, Serbia) headquarters old and new facilities were used as research objectives. IRT methodology showed the differences in thermal behavior of old and new building envelopes. This results shows that new building has slightly worse insulation properties and higher heat losses. The calculation results showed that the specific heat flow rate through the old building envelope was 6.76 W/m2, and the specific heat flow rate through the new building envelope was 15.18 W/m2.
