Building Energy Performance Metrics, Supporting Energy Efficiency Progress in Major Economie – November 2015 – “This International Energy Agency (IEA) and International Partnership for Energy Efficiency Cooperation (IPEEC) report supports energy efficiency in major economies by providing the metrics data needed to gauge progress and identify opportunities for improvement in building energy performance. The focus is on building energy use and metrics over the period 2000 to 2012 for the sector as a whole and for residential and services buildings separately.  Key historic drivers of building energy use are discussed, such as population, building sector size, economic activity, building energy policy, among others. Forecasts of building energy use and savings potential are also provided up to the year 2050. The data and analysis in this report may inform policy and technology-related action at the national level and in international fora such as the MEF, the G20 and IPEEC.”
