Cool Roofs in Europe - Initiatives and Examples

Il Caso Evidenziato October 2010
Share this Post:
Five case studies were implemented, within the framework of the Cool Roofs project, to demonstrate cool roof capabilities in real buildings, in terms of improving the thermal conditions in non-air conditioned buildings and reducing the energy consumption in air-conditioned buildings. The case studies were monitored, in regard to their energy performance and indoor environment, before and after the implementation of a cool roof technology. The buildings were selected to achieve maximum geographical and building typology coverage aiming to promote the benefits coming from this technique with reference to cooling energy demand and peak savings all around the EU. The corresponding activities were performed at two levels: • experimental monitoring in real buildings treated with Cool Roof techniques (hardware task) • numerical analysis of the same buildings with a number of variants (software analysis) The findings of the case studies show 10-40% energy savings and 1.5-2°C reduction of the indoor temperatures, depending on the climatic conditions.
