Detailed simulation of heat transfer across planar evacuated glazing

The centre of glass thermal performance of evacuated glazing is better than the performance of argon‐filled atmospheric pressure double glazings. Mitigation, or elimination of evacuated glazing edge effects will bring total window thermal performance on par, or better than, competing ‘superwindow’ options; thus increasing the commercial attractiveness of these glazings. The results of the computer‐based thermal modelling at the Universities of Sydney and Ulster compare well with each other and with the infrared thermography measurements at Lawrence Berkeley.
