What we will present in this paper is a detailed presentation and interpretation of the envelope performance data that has been generated. This building utilizes considerable amount of metal rainscreens and metal solar shading devices in its exterior assemblies. To date, we observed some interesting trends emerging especially with its use of the metal cladding. Interesting convective heat flows seem to be present between the metal rainscreen cavities. We also noticed what we believe is re-radiation being emitting from the metal surfaces that result in increased heat transfer through the wall assemble. Here we will be using measured data from the sensors placed in the wall assembl
