WEBINAR #11 | Status on the ground: Prevention of summer overheating — methods and results

2 December 2016

This QUALICHeCK webinar focused on summer thermal comfort by discussing available national requirements, related assessment methods, as well as results from field studies.

summer-overheatingOverheating prevention is addressed by EPBD Annex I which states that the energy performance of a building shall be determined and shall reflect the cooling energy needs (energy needed to avoid overheating) to maintain the envisaged temperature conditions. This highly important requirement for occupant’s comfort and wellbeing has led to variety of practices and regulations in Member States. In principle, overheating is a dynamic problem highly depending on the solar gain, thermal mass, shadings, window airing etc. Some countries address the issue with dynamic simulation based requirements, whereas in other countries more simplified methods are in use. Field studies show that this quite a new issue has not yet been fully established in design and construction practice and more efforts are needed for successful implementation.
