Question

Why do you think green roofs are becoming more popular?

Answer 1

Step-by-step explanation:

• Unlike traditional black tar roofs, green roofs reduce energy costs by absorbing heat instead of attracting it and providing natural insulation for buildings. According to a study conducted by the National Research Council of Canada, even a six-inch extensive green roof can reduce summer energy demands by more than 75 percent. By lowering air conditioning demand, green roofs decrease the production of associated air pollution and greenhouse gas emissions.
• Green roofs help reduce the Urban Heat Island Effect, a condition in which urban environments absorb and trap heat.
• A green roof’s plants remove air particulates, produce oxygen and provide shade. Additionally, this natural protection against extreme heat enables green roofs to last twice as long as traditional rooftops.
• Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in urban environments. Because rooftops and streets in cities are hard surfaces, the volume and velocity of stormwater runoff increases tremendously and is a major source of flooding and pollution worldwide. Due to nonporous surfaces like pavement and rooftops, a typical city block generates more than five times more runoff than a woodland area of the same size. The ability a green roof has to absorb (and filter) water significantly lowers the risk of flash flooding and sewer overflows. In the summer, green roofs retain up to 90 percent of the precipitation that falls on them and up to 40 percent in the winter.

hope this helps you.

Answer 2

Green roofs are becoming more popular because it's a sign that this universally lauded green practice. It has benefits like provide shade, remove heat from the air, and reduce temperatures of the roof surface and surrounding air. It can also help reduce heat, specifically during the day.
