cementitious surface

A strategy to reduce global warming is to increase the reflectance and thermal emittance of the built environment (Akbari, Menon, e Rosenfeld 2008). The urban heat islands usually increase the temperature by more than 10ºC (Santamouris et al. 2001).  A cool roof can reduce the temperature up to 3.3ºC (Synnefa, Santamouris, e Akbari 2007) and improve indoor thermal comfort and reduce energy consumption.
