EBC Annex 62

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. Annex 62 was running until the end of 2018.

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 9 December 2020, venticool & AIVC Webinar – “Resilient Ventilative Cooling in practice”

The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling 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. Resilient ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.

This webinar will present solutions of ventilative cooling in practice in residential and non-residential buildings. Peter Holzer, operating agent of IEA EBC Annex 80 Resilient Cooling of Buildings, will give an overview, and speakers from industry will demonstrate interesting ventilative cooling components.

This webinar is organised by INIVE EEIG (www.inive.org) with the support of the IEA EBC Annex 80 Resilient Cooling of Buildings (https://annex80.iea-ebc.org/), the IEA-EBC Annex 62 Ventilative Cooling (https://venticool.eu/annex-62-home/) and the venticool platform (www.venticool.eu), and in cooperation with the Air Infiltration and Ventilation Centre (www.aivc.org).

Presentations and Speakers:

  • Introduction to resilient ventilative cooling and venticool, Hilde Breesch – KU Leuven, Belgium
  • Ventilative cooling components: An overview, Peter Holzer – Operating Agent EBC Annex 80, Institute of Building Research & Innovation, Austria
  • Application of louvres to support ventilative cooling, Ivan Pollet – Renson, Belgium
  • Examples of air flow enhancing and natural cooling components, Nick Hopper  – Monodraught, United Kingdom
  • Controlled windows for ventilative cooling, Peter Foldbjerg – Velux, Denmark
  • Ventilative cooling integrated design, Jannick Roth – WindowMaster, Denmark

Participation to the webinar is FREE but requires you to REGISTER for the event.
