Green Roof Heat Loss

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 roof heat loss.

In summer the green roof protects the building from direct solar heat. In winter the green roof minimizes heat loss through added insulation on the roof. By lowering air conditioning demand green roofs can decrease the. Green roofs remove heat from the air through the process of evapotranspiration and also act as.

They can reduce heating by adding mass and thermal resistance value also can reduce the heat island by increasing evapotranspiration. This energy is known as latent heat. Green roofs play a major role as a sustainable solution to minimize the heat island effect. Green roofs improve and reduce energy consumption.

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. Green roofs improve air quality. Energy conservation translates into fewer greenhouse gas emissions. Co benefits of heat island mitigation strategies reduced air pollution and greenhouse gas emissions.

The positive effect on the temperature of the membrane under a green roof protects the membrane from the effects of uv frost and sunlight. Thermal reduction and energy conservation.
