WEBINAR #09 | Cool Roofs in the context of compliance and quality

Wednesday 28 September 2016

Increased urban temperatures have an important impact on the energy consumption of buildings mainly during the summer period. The urban heat island is the most documented phenomenon of climatic change. The heat island is related to the increase of urban temperatures compared to the suburban areas because of the positive heat balance.

Rejection of solar gains is the aim of passive cooling strategies in any type of building and any climatic region. Cool materials work by reflecting solar radiation and therefore rejecting solar heat gains at the opaque external surfaces of the building. Heat transfer to the internal space by conduction is therefore reduced, while the magnitude of the reduction will be determined mainly by the solar radiation intensity, the temperature difference between inside and outside, as well as the constructional characteristics of the roof. The extent of cool materials usefulness is dependent on the severity of external conditions and internal heat gains.

This QUALICHeCK webinar outlined efforts for the promotion of cool roofs, related to compliance and quality of the works in the European context, including the role and work of the European Cool Roofs Council (ECRC), cool roofs standards and the ECRC product rating programme, as well as practical experiences from relevant markets.
