Green Roofs are fast becoming one of the most sustainable and achievable ways to reduce a building’s carbon footprint and energy costs, while also providing a haven of green for building employees or residents. Green Roofs are also a great way to increase food production in urban environments.Creating a green roof can improve both the environmental quality of your building for its residents of employees, as well as playing an important part in creating a more sustainable community.
Although the term green roof generally refers to those roofs that have living matter actually growing on them (not in pots), it can also be a roof that has a substantial installation of green walls as well.
A waterproof layer is created between the roof and the material in which the plants live. In some cases, the plants chosen to grow in the green roof can also be designed to protect the biodiversity of the area (also know as brown roofs), while hardy native species that require little maintenance are chosen for others.
Green roofs have many benefits. They provide a natural thermal layer of insulation to a building, reducing the need for heating and cooling during summer and winter respectively. They also help to reduce stormwater runoff, create habitats for wildlife, and if used for food production, can contribute to urban sustainability and food security.
Available roof space for planting can be increased by the addition of green walls, which can be used to create natural shade areas, to grow fruits and vegetables, or used to improve the aesthetics of existing walls. Green roofs and walls also help to filter pollutants out of the air, and absorb carbon.
