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.


Favorite 20 April 2016, Seminar, Cork – Ventilative Cooling & Overheating Risk

Addressing the increased potential for cooling energy demand and associated risk of overheating in new and refurbished low energy buildings is becoming an important issue for the industry. This half day seminar for researchers, designers, engineers & architects, is organised by the Cork Institute of Technology in collaboration with IEA EBC Annex 62 – Ventilative Cooling and will present state of the art in utilising ventilation for reducing cooling energy demand and addressing the risk of overheating in low energy buildings.

Speakers will include both national and international researchers and practitioners showcasing various tools, techniques and projects related to ventilative cooling, presenting their most recent findings from the state of the art.
