Definition of Climatic Parameters for Calculation of Energy Performance of Buildings

Abstract

Calculation of energy performance of buildings is defined by European standards in accordance with the Directive 2010/31/EU (EPBD). One of the main goals of the Directive 2010/31/EU is the decrease of energy consumption in the buildings. Standard EN ISO 13790 prescribes the methodology of calculations of energy performance of buildings. The input data for the calculation and their interpretation are defined by European standards related to EN ISO 13790. Climate parameters are defined based on meteorological data in accordance with EN ISO 15927-4. Numerous analyses have shown that the results of calculations depend not only on the chosen method, but also on defining the climate parameters.
