Overview
CEN ISO/TR 52016-4:2024 provides detailed explanation and justification for the correct understanding and use of ISO 52016-3, which addresses the calculation of energy needs for heating and cooling, internal temperatures, and sensible and latent heat loads in buildings, particularly when incorporating adaptive building envelope elements. This technical report supports professionals and regulatory bodies to ensure consistent, transparent, and efficient application of energy performance calculations in the built environment. Developed by CEN/TC 89 and ISO/TC 163, this document accompanies the suite of EPB (Energy Performance of Buildings) standards, enabling seamless integration with national and regional regulations.
