Three forms of green roofs exist: extensive, semi-intensive, and intensive green roofs. an in depth green roof is characterised by its low weight, a skinny layer of growing medium (green substrate), a mixture of plants adapted to conditions on the roof, minimum maintenance and low installation costs.
How do green roofs save energy?
Green roofs regulate buildings' internal temperature and reduce building heating and cooling costs. Green roofs also function as sustainable, decentralized stormwater management systems by reducing run-off and decreasing the energy costs related to extending and upgrading centralized systems.
Advantages of green roofs
A green roof provides a rainwater buffer, purifies the air, reduces the ambient temperature, regulates the indoor temperature, saves energy and encourages biodiversity within the city. Green roofs are a part of climate-proof construction. What's more, people are happier in a very green environment than in grey surroundings.
Disadvantages of green roofs
• A greater expense than traditional roofs. Unfortunately for green roofs, they are doing tend to be slightly dearer than the standard option.
• An increase in weight load.
• Require extra maintenance.
