A Green Roof is a roof of a building that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane.

Stormwater Retention

• Regulatory requirements for stormwater management can be met with a green roof
• The growing medium and vegetation absorb rainwater where it is returned to the atmosphere through transpiration and evaporation
• Green roofs can also act as natural filters for any excess rainwater that happens to run off
• Delays the time at which runoff occurs resulting in decreased stress on sewer systems at peak flow times

 

Temperature Control

• Reduced cooling and heating costs
• Protects the roof membranes from harmful UV radiation and heat
• Reduces the size of the HVAC unit necessary and makes for a more efficient heating and cooling system
• Reduces the urban heat island effect

 

Improve Air Quality

• The soil, plants, layers of roof membranes, barriers and insulation reduce the noise pollution for the occupants of commercial buildings
• 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
• A green roof will not only absorb heat, decreasing the tendency towards thermal air movement, but will also filter the air moving across it

Public Benefits

• Increase local support for new development
• Aesthetically pleasing to tenants above buildings with green roofs
• Tenants or employees are provided with a rooftop oasis
• Access to the outdoors can increase productivity and morale
• Decreased need for health care services due to the benefits of passive experiences with nature and vegetation
• Increase public perception of your corporation
