EN ISO 52016-1: The new international standard to calculate building energy needs for heating and cooling, internal temperatures and heating and cooling load

Abstract

The set of Energy Performance of Buildings (EPB) standards has been published in 2017. One of the key EPB standards is (EN) ISO 52016-1, to calculate the energy needs for heating and cooling, internal temperatures and sensible and latent heat loads. This standard replaces (EN) ISO 13790:2008. Like its predecessor, ISO 52016-1 contains both a monthly and hourly method, but the hourly method in ISO 52016-1 is more advanced and better suited to deal with dynamic effects. Additional standardization work has been initiated to further increase the applicability: (1) to include the effect of adaptive façade elements and (2) to introduce specific criteria and validation procedures for alternative calculation procedures.
