Daniel Jones is a commerce/science student who joined the Solar Decathlon team in 2012. He has since begun a research masters investigating retrofitting residential houses. Team UOW designed and built a prototype to demonstrate retrofitting of a common Aussie house. Daniel is investigating how our retrofitting compares to other options available to people who own a home. The main metrics for the comparison are construction cost, operational cost, comfort for the occupants, the impact of the materials and the carbon associated with its efficiency and the materials used. Retrofitting represents an exciting opportunity for Australians to be creative and sustainable, reusing something old to create a better solution.
