Green Roof Heat Loss

Green roofs play a major role as a sustainable solution to minimize the heat island effect.

Green roof heat loss.

In winter the green roof minimizes heat loss through added insulation on the roof. In summer the green roof protects the building from direct solar heat. A 2005 study by brad bass of the university of toronto showed that green roofs can also reduce heat loss and energy consumption in winter conditions. Importantly this also moderates heat flow through a building by shading increased insulation and thermal mass.

Green roofs improve air quality. Energy conservation translates into fewer greenhouse gas emissions. Thermal reduction and energy conservation. They can reduce heating by adding mass and thermal resistance value also can reduce the heat island by increasing evapotranspiration.

Co benefits of heat island mitigation strategies reduced air pollution and greenhouse gas emissions. Because green roofs store water in the growing media and plants latent heat loss is accomplished via transpiration from plants and evaporation of moisture from the growing medium collectively referred to as evapo transpiration. Green roofs remove heat from the air through the process of evapotranspiration and also act as. By lowering air conditioning demand green roofs can decrease the.

This energy is known as latent heat. Under a green roof however the fluctuations were in the order of 6ºc.
