BENEFITS OF GREEN ROOFS

Green roof technologies not only provide the owners of buildings with a proven return on investment, but also represent opportunities for significant social, economic and environmental benefits, particularly in cities.

STORMWATER MANAGEMENT

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.

REDUCTION OF ENERGY USAGE

Green roofs offer cooling temperature control in hot summer months, reducing the demand for air-conditioning, and studies have shown in winter heating bills can be reduced by over 10%.

NOISE REDUCTION

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.

GOVERNMENT AND DISTRICT INCENTIVES

Many cities and districts such as London offer grants or incentives when using a green roof solution.

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.

ENHANCES AESTHETICS

Green roofs offer aesthetic quality and human dimension to the urban design for creation of a more pleasant cityscape, enhancing the visual interest of the city scene and vibrancy of the city life.

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.
