Promotion of COOL ROOFS in the EU
September 2008 – January 2011
National and Kapodestrian University of Athens
The aim of the project is to create and implement an Action Plan for the Cool Roofs in EU. The specific objectives were:
- To support policy development to heating and cooling consumption in the EU by cool roofs;
- To remove market barriers in construction and building's stock;
- To change the behavior of decision-makers and stakeholders so to improve acceptability of the cool roofs;
- To disseminate and promote the development of innovative legislation and standards, including cool roofs.
The work will be developed along four axes: technical, market, policy and end-users.
A “cool roof” is a term for roof envelope increased reflectance (of lowered emittance) which decreases the heat penetrating into the building. During the summer, this results in lower cooling loads if it is an air-conditioned building, or in more comfortable thermal conditions if the building is not air-conditioned.
The large-scale use of cool materials in an urban area leads also to indirect energy savings due to the reduction of the air temperature at the urban level. The indirect benefits arise from this ambient cooling that will decrease the need for air-conditioning. Cool roofs are a way how to provide passive cooling in the urban area.
Cool roofs typically yielded measured summertime daily air-conditioning savings and peak demand reductions of 10 to 30%.
The Cool Roofs project has reached successful competation by end of February 2011!
