Abstract: Among the objectives of the Directive 2002/91/EC and of the Council ||Energy performance of buildings||, Energy Performance of Building Directive (EPBD) the energy certification of buildings represents a fundamental role. The method here described starts from the LowEX tool, previously developed in the IEA ECBCS Annex 37 framework. By using the exergy approach, new (non-economic) indices could be utilised, as Tonne of Oil Equivalent (TOE), CO₂ emission, or not-renewable energy uses. The ratio between TOE produced by the boiler and the exergy used by the system represents the exergy parameter.

Keywords: wrapper energy; exergy analysis; energy typology architecture; comfort; energy performance; buildings; energy consumption.
