Green roofs can help regulate a building’s internal temperature, reduce stormwater runoff, and mitigate the urban heat island effect. Green roofs also provide an opportunity for urban food production, and increasing urban biodiversity. The idea: Light-colored materials reflect heat, while dark roofs, such as those made of asphalt and tar, absorb heat, driving up air-conditioning consumption in order to offset it. Although green roofs are initially more expensive to construct than conventional roofs, they can be more economical over the life span of the roof because of the energy saved and the longevity of roof membranes (Porsche and Köhler 2003). Green Buildings Could Save Our ... Green roofs reduce storm runoff and help mitigate the urban heat ... lower operating and energy costs mean that green … Because green roofs protect the roof membrane from harsh weather and ultraviolet (UV) radiation, they can last twice as long traditional roofs. n Green Roofs and cool roofs can save energy, reduce neighborhood temperatures, and protect human health. One way to estimate how much energy you would save by installing a cool roof is by using the Cool Roof Calculator. 2. Roof Gardens and Energy Savings .

Roof gardens keep flat roofs cool in Summer – and also help insulate in winter. An exposed roof can get as hot as 158 degrees on a sunny day, while a green, shady roof heats to just 77 degrees, according to the council. Green roofs have been proven to bring about significant energy savings, particularly during the summer cooling season in which single story buildings can experience a reduction of greater than 25% energy use for air conditioning.
