In this project, RMIT is completing building simulation exercises which compare the performance of thermochromic glazing systems in different climates.
Theoretically thermochromic (TC) glazing has the potential to reduce energy consumption in building: allowing visible light for daylight, reducing unwanted solar gain during the cooling season, whilst allowing useful solar gain in the heating season. A prototype glazing using vanadium dioxide films has been produced its thermochromic properties measured and tested. The potential energy savings have been compared to standard glazing types and verified by the use of building simulation.
The films will be produced using chemical vapour deposition techniques. Queen Mary University is completing experimental work producing new thermochromic coatings, followed by physical measurement and analysis of the performance of novel thermochromic materials.
