Service Buildings Keep Cool: Promotion of "sustainable cooling" in the service building sector (KEEPCOOL)

Download PDFDownload PDF
Demand for cooling energy is expected to rise dramatically in Europe in the coming years, despite better understanding of passive cooling technologies. The aim of this project was to propose intelligent ways of getting passive cooling to penetrate the market and to establish a new definition of sustainable summer comfort.


  • A tool-kit explaining the ten steps to achieve sustainable summer comfort is available. This online tool includes technology profiles, best practice examples in English and national languages, supplier and expert lists, and an analysis of comfort legislation in participating countries.
  • An awareness-raising campaign on summer energy consumption took place and included articles in the daily and technical press, international conferences and technical workshops, two online encyclopaedias, radio and TV broadcasts.
  • The sustainable summer comfort message was conveyed to 500 owners of individual buildings, as well as many others with large property portfolios.
  • KeepCool succeeded in including the Adaptive Comfort Model into the European Standard EN 15251 and in removing further barriers towards the use of passive cooling solutions.
  • This action now continues under the Keep Cool II project which aims at providing analysis and technical tools, as well as addressing existing networks and policy makers regarding sustainable summer comfort.

Lessons learned

  • Even in buildings with high comfort requirements, passive cooling solutions can significantly improve energy efficiency. In existing air-conditioned buildings, great savings can be achieved in a comprehensive refurbishment following the principles of sustainable summer comfort and re-sizing the ventilation and AC equipment.
  • Conversely to the air conditioning industry, the passive cooling industry is very scattered. Therefore, a structured supplier-customer dialogue is very helpful to develop the market.
  • Direct contacts to decision makers turned out to be the most effective measure for market development. However, the key target group varied locally, between trade associations, architects/planners, building owners and the suppliers of passive cooling solutions. Other dissemination activities should facilitate such direct contacts: Architecture competitions or other events are a good condensation point, easily accessible information in national language an indispensable backup.
