The EnEV is a performance-based code that requires a mandatory (equivalent model building) energy frame calculation to establish the expected primary energy consumption of residential and non-residential buildings. The regulation addresses thermal envelope requirements and energy using or producing systems in the calculation, including, HVAC, hot water, lighting (non-residential only), bio-climatic design and renewable energy.
Germany has had prescriptive building energy efficiency requirements since 1977. The first performance-based code was introduced following the implementation of the EPBD in 2002. The 2009 version and supporting policies encompasses many progressive aspects including, low maximum u-values established relevant to climate, mandatory computer simulation, air-tightness requirements, well established incentive schemes, frequent boiler and HVAC testing, robust EPC programs, voluntary low energy classes, and a national target for carbon free buildings by 2020.
