Green Roofs are not just a form of contemporary architecture, but also give a new value to the role of buildings within urban planning. They are designed to bring back the natural element in the urban environment as well as provide solutions for key issues as ‘Urban Heat Island’ effect.
Desert Dream Gardens is exclusively supplying the successfully tested extensive SemperGreen Green Roof system, giving excellent and high performance in the Middle East.
Extensive green roofs have shallow total thickness, about 10-12cm. They support sedum, herbs, grasses and other vegetation where low maintenance is required. They are the lightest type of green roofs.
The meaning of sustainability is developing in a wider view. From the building lifecycle perspective, the environmental impact of a building is equally determined by its energy consumption, the use of renewable energy and the use of sustainable materials. Green roofs is an effective sustainable contribution to buildings.
Extended roof life: Green roofs could triple the life expectancy of the roof. The underlying roof materials are protected from mechanical damage, ultra violet radiation and extreme temperatures, resulting to reduced maintenance and renovation costs.
Energy efficiency: Green roofs could help reduce energy consumption by 100% for cooling in summer (in combination with the e.g. type of construction)
Noise reduction: Our green roof system provides good sound insulation, keeps the living space quiter and creates pleasant surroundings in urban areas, also in the form of Instant Ground Coverings. It contributes to noise reduction in cities, near industrial areas and airports.
Reduction of ‘Urban Heat Island’ effect (UHI): Green Roof very effectively help reduce the air temperature in urban areas. In summers, the temperature in cities are about 5-7°c higher compared to the countryside due to buildings and road heat absorption. Temperature on a traditional roof could be 40°c higher compared to a green roof.
Tyndall Centre for Climate Change: 10% more greenery required to reduce the UHI effect.
Rainwater retention: Green roofs help reduce runoff of storm water due to heavy rainfall, decreasing the burden on sewer systems. Costs are saved for e.g. manpower and equipment used for rainwater management.
Rainwater purification: Through natural bio-filtration, green roofs prevent contaminants and toxins from reaching streams and waterways, helping to improve local water quality.
CO2 reduction: Green roofs contribute to reducing CO2 in the air, an important causer of global warming. 1m³ of green roof can absorb 5Kg of CO2 yearly. Additionally, due to lesser energy consumption, there could be a further CO2 reduction by 3.2Kg.
Cleaner air: The plants on green roofs can catch airborne particles as smog, heavy metals and Volatile Organic Compounds. This has a positive effect on the air quality and health of inhabitants.
Natural habitat: Increasing urbanization is challenging local authorities to ensure biodiversity in their surroundings. Green roofs can help restore the ecological cycle disrupted by urban infrastructure
Natural look: Green roofs provide relief from the concrete construction in urban areas, introducing substantial changes to modern architecture. Presence of green roofs could have a relaxing psychological effect, blood pressure reduction and lowering of heartbeat. These benefits of green roofs could additionally increase residential and commercial property values.
Usable green space: Green roofs provide additional green space in urban areas with limited open space and add value to buildings.
