EU: a comparative methodology to assess building energy performance
A Regulation Executive (EU 244/2012) has been published in the Official Journal of European Union, in order to integrate 2010/31/UE Directive of the European Parliament and Council Directive on Buildings Energy Performance.
The Regulation aims to create a comparative methodological framework available to Member States in order to calculate the optimal levels of costs and minimum energy performance of new and existing buildings.
The Member States retain the ability to set minimum energy performance of buildings - and building elements - and the comparative method has the task of assessing whether the targets are actually directed toward the achievement of energy savings expected from the EU. For this purpose, each Member State must compare their goals with those predicted by the comparative method and justify any deviations.
Member States must submit a detailed report including specifically:
- The primary energy conversion factors applied;
- Results of calculations for financial and macroeconomic levels;
- The sensitivity analysis of calculation results in changes of the parameters involved;
- The expected development of prices of energy and carbon.
