Transforming the market from "cooling" to "sustainable summer comfort". (KEEP COOL II)

Download PDFDownload PDF
The overall goal of the project KeepCool II was to transform the market to achieve good summer comfort conditions with no or limited use of conventional energy and through the use of environmentally non-harmful materials instead of installing conventional air conditioning systems. The project proposed different actions to achieve this goal. For this it was divided in two phases. The first one provided analysis and technical tools to overcome the most important barriers. The second phase was addressing existing networks and policy makers on national and European level by providing information material with sound facts, tools and best practice examples designed especially for the target groups. Target group: - Suppliers and retailers of various sustainable summer comfort solutions - Architects, planners, HVAC designers, construction companies - Building owners, building users - Energy consultants - Facility managers and O&M staff - Public procurement organisations - National and regional institutions for building regulations and energy policy - International audience


  • Market transformation: In each participating country, at least 200 professionals (suppliers and retailers of various sustainable summer comfort solutions, architects, planners, HVAC designers, construction companies, building owners, building energy consultants, building users, facility managers and public procurement organisations. Half of them should cooperate with each other to achieve the "service" summer comfort.
  • Sustainable summer comfort in Energy Efficiency Action Plans: The EEAP of three different countries should be influenced
  • Sustainable summer comfort in national Building Codes: Three countries should have influenced their building regulation.
  • Dissemination activities of sustainable summer comfort: Information material on sustainable summer comfort has to be produced and used by at least 10 professional networks per participating country
  • International level: An Observers Group hast to be established, which has 20 members covering a large number of Member states. The results and the materials should be actively used by at least 5 members of the Observers Group

Lessons learned

  • - The simulations showed that high energy savings are possible with quite easy and cost effective measures. The installation of Venetian blinds, ideally directed automatically depending on the solar radiation, as well as free cooling or night ventilation etc. can have a major influence on the energy savings for cooling and also on the indoor comfort for the building users.
  • The simulations showed that the insulation of the roof can result in higher cooling needs because the heat can not escape. However, the heat energy demand would decrease by applying additional insulation. Thus it has to be carefully analysed if the better insulation of the roof is suitable for a specific building.
  • The combination with other projects in a related field seems important to interlink the results, to adjust activities and to learn from other projects. The cooperation with HARMONAC which focuses on inspection of air conditioning systems allowed professionals mainly interested in efficiency to be aware of the need to reduce cooling needs at the beginning importance of minimising the cooling
