Foremost, it is up to national/regional authorities to specify which climatic data set(s) shall be used for the EPB assessment in the context of national/regional building regulations.
As default climatic data sets for any EU location, the European Commission recently supported its Joint Research Centre (JRC) to develop typical meteorological years (TMY).
A TMY is a set of meteorological data with data values for every hour in a year for a given geographical location, e.g. for calculating the energy performance of buildings.
EN ISO 52010-1 deals with the conversion of climatic data for the energy performance calculations.
An updated version of the spreadsheet for EN ISO 52010-1 is in preparation as support for users. This spreadsheet helps users with the conversion of measured hourly solar irradiation data into irradiation at a plane of any orientation and tilt angle, in accordance with EN ISO 52010-1.
The updated spreadsheet will also be able to handle TMY files from JRC’s website.
