According to the Intergovernmental Panel on Climate Change (IPCC) the building sector has the highest potential to reduce energy use (and resultant carbon dioxide emissions) at the lowest cost. The sustainable building agenda is well recognised and rapidly growing in developed countries; however, in most developing countries with the largest and fastest growing building markets, resource efficiency and sustainability objectives are largely neglected in both construction and occupancy periods (UNEP, 2013). Consequently, the world’s most populous regions run the risk of locking their economies into inefficient and environmentally detrimental building stock for decades unless efforts are made to introduce and mainstream sustainable building practices. This is especially problematic where in these developing countries there is not only an expansion in construction but there is a large and growing need for affordable housing.
