This document is intended to present the case study and to discuss the contents of EN ISO 52010-1:2017, Energy performance of buildings — External climatic conditions — Part 1: Conversion of climatic data for energy calculations.

It also shows how the output can be directly used as input for EN ISO 52016-1 Energy performance of buildings — Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads — Part 1: Calculation procedures (ISO 52016-1:2017). The climatic data are obviously an important input for the calculation of the energy needs and internal temperatures of a building.

However, the output is also intended to be used as input for other EPB standards, such as the standards on photovoltaic systems and thermal solar systems.

EN ISO 52016-1 contains a choice between a monthly or hourly calculation interval. An hourly calculation interval is strongly preferred for reasons explained e.g. in webinars 4 and 8. An hourly calculation interval requires that hourly climatic data are available. Consequently, in this document also attention is paid to demonstrate how publicly available hourly datasets for all locations in Europe (and beyond), made available by the EC Joint Research Centre (JRC) can be easily generated, converted and used.

Some of the work has been applied in the frame of webinars from the EPB Center, see links below.
