Comparison of the Experimental Measurement Methods for Building Envelope Thermal Transmittance

Building energy consumption and ways to reduce it have drawn increasing attention in recent decades. Thermal transmittance is not only a code-enforced parameter during the design retrofit phase of building assemblies, but also strongly related accuracy whole-building modeling. There are several existing methods measure envelope thermal transmittance, with development new techniques, more practical precise measurement been explored. The study discussed here focused on comparing both laboratory for in-situ measurement. Typical research studies Hot Box Test Method, Heat Flow Meter Method Infrared Thermography described compared. This paper provides state-of-the-art review up-to-date alternatives engineers, architects researchers practically transmittance.
