Green Roof From Above

For intensive green roof profiles a drain restrictor may be used to retain water in the base of the profile for subsequent plant transpiration.

Green roof from above.

Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect particularly during the day. Green roofs provide shade remove heat from the air and reduce temperatures of the roof surface and surrounding air. An extensive green roof is a thin usually less than six inches lightweight system that is typically predominantly planted with succulents drought tolerant ground covering plants and grass. Types of green roofs.

A green roof is a roof that is partially or completely covered with vegetation and soil planted over waterproofing membrane. Over a black roof flat. The additional thickness of the growing medium provides extra thermal insulation. This green space could be below at or above grade but in all cases it exists separate from the ground.

A membrane is the bottommost layer of a green roof and is the main separation between the green roof above and the structural supports below. Greening a roof is not simple or cheap. Germany where about 10 percent of roofs are green is the leader. In truth this should be the future as this approach provides the greatest range of benefits.

Some parts of germany require green roofs on all new buildings. Due to the excessive water amounts associated with green roofs the membrane must be strong enough to support this water weight and to not let it seep through. Especially if it is designed specifically for biodiversity. Green roof development involves the creation of contained green space on top of a human made structure.

A green roof moderates the heat flowing through the roof. This helps to reduce temperature fluctuations caused by solar radiation. The smartest green roof is one where the green roof element above a blue roof is a biosolar roof a green roof that houses solar panels.
