Green Roof Heat Loss

Green roofs improve air quality.

Green roof heat loss.

Green roofs improve and reduce energy consumption. Green roofs play a major role as a sustainable solution to minimize the heat island effect. This energy is known as latent heat. Co benefits of heat island mitigation strategies reduced air pollution and greenhouse gas emissions.

In summer the green roof protects the building from direct solar heat. They can reduce heating by adding mass and thermal resistance value also can reduce the heat island by increasing evapotranspiration. Green roofs remove heat from the air through the process of evapotranspiration and also act as. 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. In winter the green roof minimizes heat loss through added insulation on the roof. 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.

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. By lowering air conditioning demand green roofs can decrease the.
