A green roof can hold up to 80% of stormwater runoff, to help prevent flooding and lessen the impact on city drainage structures.
INCREASED ROOF LIFESPAN
Studies have shown that a green roof can increase a roofs average lifespan by up to 3 times.
A combination of the substrate, vegetation, and air locked within the green roof system acts as sound insulation, with tests showing reduction in noise of up to 50dB.
HEAT ISLAND EFFECT
Urban areas have a high temperature average compared to rural areas due to the lack of green space. Vegetation from green roofs improves microclimate by absorbing heat and reducing the temperature of hard surface, and enhancing the humidity.
HABITAT SPACE FOR RARE WILDLIFE
Green roofs provide a rich habitat for small insects and invertebrates to breed within an urban environment.
INCREASE SOLAR PANEL/PV EFFICIENCY
Green roofs help to maintain the efficiency of solar panel systems by keeping PV panels cool and help to maintain an ambient temperature of 25 ℃ needed for maximum energy absorption.
PROVISION OF GREEN & AMENITY SPACE
Green roofs provide much needed green space within our rapidly growing urban environment to help soften built up areas, and contribute ecological function.
MORALE AND PERFORMANCE
Studies show that visible and/or accessible green roofs on commercial rooftops can improve morale and productivity through psychological comfort and relief.
IMPROVED AIR QUALITY
Through the process of photosynthesis, plants absorb carbon dioxide and release oxygen, refreshing the surrounding air. They also absorb harmful gases such as sulphur dioxide and nitrogen oxide within the atmosphere and help break down noxious gas emitted from vehicles or industrial activities.
