This research updates the 2011 study by Assoc. Professor Sara Wilkinson on the importance of environmental retrofitting of commercial buildings in the Melbourne, Australia. This second study seeks to gain a deeper understanding of improvements made to the building stock through the City of Melbourne's 1200 Buildings Program. Adaptation of the existing building stock is an essential component in attempts to mitigate the effects of global warming, given that 87% of the stock that will be here in 2050 is already built and secondly that 40% of all greenhouse gas emissions are derived from the built environment. In Australia the majority of Australian stock has been designed with little or no consideration of energy efficiency and sustainable retrofit become more of an imperative going forward. In 2008 the City of Melbourne launched the 1200 Buildings Program as a key strategy to deliver carbon neutrality by 2020. In retrofit multiple attributes are important and they can be labelled as economic, location and land use, physical legal, and social. The question is; which attributes are of most importance in office building retrofits? This research provides answers to this question in the context of the Melbourne stock. Significantly this study examined all CBD retrofits from 2009 to 2011 to establish which attributes were of most importance. The findings show that legislation aimed at integrating sustainability into the built environment through the Building Code of Australia and Mandatory Disclosure is having an impact on retrofits.
