The roof is a forgotten element on most buildings. Unnecessarily. Designed and built as a sustainable element, roofs can be environmentally friendly and aesthetically pleasing.
On a large scale, greenroofs reduce “greenhouse gas emissions”, have an impact on humidity, air quality and reflect heat into surrounding neighborhoods. In conjuction with other green installations, greenroofs can play a role in altering the climate and even the weather of a city as a whole. Greenroofs also remove heavy metal particulate materials from rainwater and dramatically reduce runoff and decrease the need to expand or rebuild related infrastructure. Greenroofs reduce exterior noise pollution, often by 40 to 50 decibels. Tax credits for greenroofs are available in some jurisdictions including New York, Chicago, and Seattle. The many benefits of greenroofs just keep cascading.
