However, there are potential issues associated with rooftop gardens. When roofs are covered with gardens, the gardens can block sunlight from being able to reach different areas of a building. This can lead to increased energy usage.[15] Trees growing on the roof can also lead to increased loads on the roof and it may be necessary to have taller buildings for taller trees. Another issue is that roof gardens will most likely increase the weight of the roof and if not well designed it could lead to a failure of the roof material.
In addition, the use of technology, such as hydroponic systems and LED lighting, allows for highly efficient and high quality rooftop gardens. The use of solar panels and heat exchangers, along with the use of low-watering and low-maintenance plants, allows for a more economically viable roof garden.
When gardens on the roof are used in places where they receive sun the plants are more likely to grow and develop. This can lead to vegetation that is more vigorous and generates more heat than in green spaces with lower levels of sun exposure.[16] Some people find the sound of wind blowing through the plants a nuisance. Noise can be controlled with materials and structures that prevent the noise from propagating. Noise can also be reduced by planting plants in accordance with the building's architecture.
Green roofs can be used as a suitable alternative to many of the existing urban spaces. They can be placed on most of the building's surface and the roof can be used for recreational, ornamental, or ecological purposes.
The space inside the building may be used in a number of different ways. Plants and trees can help to provide a more pleasant environment. They can also be used for decorative purposes and improve the overall look and feel of a building. They can be used as a form of energy production through photosynthesis. A building may be built with the intention of generating electricity from the sunlight that is able to reach the roof. The use of green roofs also has advantages for people who live in tall buildings.
In October 2011, Roofs.org , a non-profit organization, released a book titled Green Roofs for Small Spaces , with a foreword by writer Tim Chang. It describes how small roof gardens can provide a functional green roof, and examines the potential for small gardens to provide food, shelter and therapeutic benefits to people.
Lille, France, for example, uses an innovative roof garden for the first time in Europe. It was built on the roof of the City Hall and looks like a green dome, planted with more than 100 varieties of flowers and herbs. It is the brainchild of Cajetan , a Dutch company. It was built without traffic restrictions and without negative effects on the environment; it is the first green roof in the world that is not built on a special or industrial building.
On top of the Museum of Modern Art in New York, a newly installed green roof will welcome visitors to the museum, which has been criticized for not using green roofs where other buildings might have used them. 827ec27edc
