Annex 62 Home

Welcome to IEA EBC Annex 62 – Ventilative Cooling!

The Executive Committee of the IEA Energy in Buildings and Communities programme (IEA EBC) approved the IEA EBC Annex 62 on Ventilative Cooling in November 2013. This Annex 62 will continue in a four year working and reporting phase from 2014 – 2017.

The current development in building energy efficiency towards nearly-zero energy buildings represents a number of new challenges to design and construction. One of the major new challenges is the increased need for cooling arising in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter during periods of occupation. In order to address these cooling challenges of buildings, the research focus of the annex will be on development of design methods and compliance tools related to predicting, evaluating and eliminating the cooling need and the risk of overheating in buildings as well as on the development of new attractive energy efficient ventilative cooling solutions.

 “Ventilative cooling for buildings may lead to cooling energy savings and improvements in thermal comfort, especially in seasonally temperate and warm climates. But, codes and regulations need to better quantify its benefits”, says professor Per Heiselberg, operating agent of IEA EBC annex 62 in his article “The state-of-the-art for ventilative cooling” included in the latest issue of IEA EBC news.

The November-2016 newsletter also features information on annex 63 “Implementation of energy strategies in communities”, annex 64 “Optimised performance of energy supply systems” , annex 66 “Occupant behaviour modelling tools” and an article on how benchmarking benefits Australia’s buildings.
