Green Roof Heat Loss

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

Green roof heat loss. They can reduce heating by adding mass and thermal resistance value also can reduce the heat island by increasing evapotranspiration. In winter the green roof minimizes heat loss through added insulation on the roof. Energy conservation translates into fewer greenhouse gas emissions. Green roofs improve air quality.

This paper discusses about the effects on the surrounding temperatures if the existing flat roofs in the. This energy is known as latent heat. Under a green roof however the fluctuations were in the order of 6ºc. By lowering air conditioning demand green roofs can decrease the.

The positive effect on the temperature of the membrane under a green roof protects the membrane from the effects of uv frost and sunlight. Green roofs remove heat from the air through the process of evapotranspiration and also act as. 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. Thermal reduction and energy conservation.

Importantly this also moderates heat flow through a building by shading increased insulation and thermal mass. Co benefits of heat island mitigation strategies reduced air pollution and greenhouse gas emissions.
