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. Ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.

The objective of this workshop was to discuss the implementation of ventilative cooling and its role to guarantee good thermal summer comfort in commercial, educational and residential buildings.

Topics addressed:

  • Design guidelines
  • Solutions and technologies
  • Demonstration in current buildings
  • Energy performance calculation
  • Recommendation for standards
  • Future challenges and opportunities


This workshop presented the outcomes of IEA EBC Annex 62, discussed with experts from industry and interacted with the audience through interactive voting and group discussion.
