During heavy rainfalls, runoff from surfaces such as pavements and rooftops can cause serious problems such as sewer overflow and water pollution. Studies show that green roofs assist with reducing the effects of this. The Urban Heat Island Effect . Water stored in the growing media is released through evaporation and evapo-transpiration. The urban heat island is the overheating of urban and suburban areas, relative to the surrounding countryside, due to increased paved, built-over, and hard surface areas. Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in … A green roof acts as a superinsulator, enabling the home to hold in more heat during the winter and keep out the heat during the summer. But buildings that can bear the load tend to perform better, and they also showcase the owner’s commitment to sustainable building operation. Below we explain … What’s more, people are happier in a green environment than in grey surroundings. The benefits include increased energy efficiency (from cooling in the summer and added insulation in the winter), longer roof membrane life span, sound insulation and the ability to turn wasted roof space into various types of amenity space for building occupants. Both air con and the generation of heat create CO2. Urban areas tend to have a lot of hard surfaces like roads and concrete slabs. Green roofs filter particulate matter from the air, retain and cleanse storm water and provide new opportunities for biodiversity preservation and habitat creation.

Green roof vegetation brings rooftop temperature down to ambient air temperature. On hot summer days, the surface temperature of a vegetated rooftop can be 10 degrees cooler than the air temperature, whereas the surface of a traditional rooftop can be up to 20 degrees warmer. Introduction to Green Roof Benefits. A Green Roof is the way of the future. As such, technical performance depends on the building, climate, region, and type of green roof. They generate aesthetic benefits and help to reduce the ‘urban heat island effect’ – the overheating of cities in the summer which contributes to air pollution and increased energy consumption. When it comes to intensive green roofs, they represent new additional green space for rest and relaxation.

Storm water retention rates are determined by saturated infiltration capacity, thickness of the growing media, field capacity, porosity, under-drainage layer water retention and flow, and relief drain spacing. The extent of the energy cost savings impact is a function of: Green roofs help to protect roofing membranes from extreme temperature fluctuations, the negative impact of ultraviolet radiation, and accidental damage from pedestrian traffic. Green or living roofs are roofs that facilitate the growth of shrubs, trees and other vegetation.
