Energy performance of buildings. External climatic conditions - Conversion of climatic data for energy calculations Ingestion-build-276583 BS EN 60051‑1 is a1 Scope This document specifies a calculation procedure for the conversion of climatic data for energy calculations. The main element in this document is the calculation of solar irradiance on a surface with arbitrary orientation and tilt. A simple method for conversion of solar irradiance to illuminance is also provided. The solar irradiance and illuminance on an arbitrary surface are applicable as input for energy and daylighting calculations, for
