SPR (and its predecessors) have been undertaking these studies for the Australian Government Department of Climate Change, Energy, the Environment and Water since 2012, drawing on data from the Australian Bureau of Statistics (ABS), AEMO, CSIRO and many other sources. They provide key historical data and forecasts for the commercial building sector in Australia, including an annual count of buildings for each of 85 SA4 regions in Australia, by state and territory and climate zone, for each of the 15 major building types in the Australian Bureau of Statistics Functional Classification of Buildings (2-digitlevel), with projections to 2050. The study, and accompanying online data tables, also provide estimates of gross floor area, electricity consumption, gas consumption and greenhouse gas emissions. These studies are used for many purposes by governments, industry and researchers, including to estimate Scope 3 greenhouse gas emissions for financial institutions lending to this sector.
