Green Roof Installation

Benefits

Description

Cost Savings Opportunities

It is estimated that green roofs will last up to twice as long as conventional roofs.

Savings on energy heating and cooling costs. Through the daily dew and evaporation cycle, plants on vertical and horizontal surfaces are able to cool cities during hot summer months. In the process of evapotranspiration, plants use heat energy from their surroundings (approx. 592 kcal per L of water) when evaporating water. One m2 (10.76 ft) of foliage can evaporate over 0.5 liters of water on a hot day and on an annual basis the same area can evaporate up to 700 liters of water.

Economic Benefits

Will not only absorb heat, decreasing the tendency towards thermal air movement, but will also filter the air moving across it.

Carbon Dioxide/Oxygen Exchange - Through the process of photosynthesis, plants convert carbon dioxide, water and sunlight/energy into oxygen and glucose. This cyclical process supplies animals and humans with oxygen and food.

Sound Insulation

Soil, plants and the trapped layer of air can be used to insulate for sound. Sound waves that are produced by machinery, traffic or airplanes can be absorbed, reflected or deflected. The substrate tends to block lower sound frequencies and the plants block higher frequencies.

Amenity Space and Aesthetics
  • Aestheic appeal, increasing the value of the property and the marketability of the building
  • Potential to improve employee productivity
  • Potential for grants related to energy efficiency and/or green roofs.
  • Potential for density bonusing/larger floor area ratio.
  • Potential for satisfying minimum parkland/green space set aside, requirements.
  • Potential for greenhouse gas emissions trading credits, stemming from energy savings.
