Abstract: In this paper, we outline an innovative and robust approach to undertaking energy efficiency potential studies in large building samples. This Macro Modelling Process relies on building science and established energy simulation techniques. The process features the development of building archetypes, each representing a large class of buildings in the market. These archetypes are calibrated to the best available building energy use statistics. A demonstration of the process using data from a large study for the Canadian federal government shows that: • The process is cost-effective in comparison with hour-by-hour simulation, • The full modelling approach accounts for energy end use interactions, and • The process can be used to develop a detailed picture of energy use in a large group of buildings, despite a lack of detailed energy consumption data.
