Summer comfort and air conditioning in Europe: Actual trends and perspectives

Share this Post:
The recordings of the ASIEPI webevent on "Summer comfort and air-conditioning in Europe: Actual trends and perspectives" are now available on Whereas in the past a major challenge was to keep our buildings sufficiently warm, recently and in new buildings the challenge is also to guarantee reasonable comfort conditions in summer with no, or at least minimum, cooling energy. The EU project ASIEPI has held a web event on the current status and the new developments in different countries concerning these issues.
The main objectives of ASIEPI WP7 are to create or increase awareness of the MS around available alternative techniques and technologies that improve thermal comfort without increasing the energy consumption and how to assess the energy performance of such techniques. The activities within this WP cover a collection and analysis of the situation of the EPBD implementation in those Member States who already have specifications regarding summer comfort and air-conditioning. In parallel, studies have been performed regarding how the implementation of alternative cooling techniques and the respective advanced calculation methods into the existing calculation methods are addressed.

The web event on June 17th has provided an overview of the possibilities and barriers for penetration of innovative and passive cooling techniques into the European market,  including:

- a presentation of the European thermal comfort standards,
- an analysis of the pros and cons of the calculation methods emphasizing the role of  thermal mass, solar gains and shading, intensive night ventilation and the use of  natural cooling techniques,
- major trends in the systems used and discussions about the existence of a framework for assessing passive cooling and low energy cooling systems.
