List Two Benefits Of A Green Roof

Container gardens on roofs where plants are maintained in pots are not generally considered to be true green roofs although.

List two benefits of a green roof.

A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane it may also include additional layers such as a root barrier and drainage and irrigation systems. Green roofs reduce stormwater runoff. Benefits of a green roof a green roof has many benefits at economic ecological and societal levels. By avoiding exposure to extremely high and low temperatures the roofing will last two to three times longer than with a traditional roof.

Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in urban environments. Green roofs can help reduce energy costsfor a building by acting as another layer of insulation between the inside and outside of the roof. A green roof provides a rainwater buffer purifies the air reduces the ambient temperature regulates the indoor temperature saves energy and encourages biodiversity in the city. While all green roofs have similar functions each installation is unique so technical performance will vary by region climate building and green roof type and design.

A green roof s plants remove air particulates produce oxygen and provide shade. Green roofs are part of climate proof construction. Extra features such as bird baths and beehives can be added to boost the roof s ecological impact. This is most noticeable in intensive green roofs since there is a thicker and more consistent layer of soil which provides a higher insulating value.

Reduced heating and cooling costs. Longer lifespan of the roofing a green layer protects the roofing against uv radiation snow and ice. Additionally this natural protection against extreme heat enables green roofs to last twice as long as traditional rooftops. Green roofs provide a host of health and economic benefits for the homeowner the community and the environment.

The benefits described below can be achieved by virtually all green roof systems and designs. Over its estimated lifespan of 40 years a green roof would save about 200 000 of which nearly two thirds would come from reduced energy costs. The study looked at a range of benefits of green roofs including stormwater management improved health benefits due to reduced pollution and energy savings.
