The solar reflectance of green roofs varies depending on the plant types (generally 0.3–0.5). [29] Green roofs may not reflect as much as a cool roof but do have other benefits such as evapotranspiration which cools the plants and the immediate area around the plants, aiding in lowering rooftop temperatures but increasing humidity, naturally.
A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...
A subtropical climate vegetated roof (SCV roof) is a type of green building practice that employs a planted soil media installed above a waterproof roof deck to obtain environmental benefits and address sustainability concerns, similar to traditional green roofs located in northern continental United States. Soil media, plant palettes, and ...
Green roofs - Living, vegetative roofing alternatives; a solution to the heat island effect associated with buildings. Low-VOC paints - Drastically limits any odorous, harmful, or irritating emissions and enhance the occupants' comfort. Compact fluorescent bulbs - Uses less energy and give off less heat; will save energy used to cool the building.
There are two types of solar water systems: active and passive. An active solar collector system can produce about 80 to 100 gallons of hot water per day. A passive system will have a lower capacity. [21] Active solar water system's efficiency is 35-80% while a passive system is 30-50%, making active solar systems more powerful. [22]
The potential benefits from these investments are estimated at about $4.3 trillion by 2030, offering a substantial economic return of 16-to-1. [224]: 7–8 Mitigation measures in the food system can be divided into four categories. These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains.

In 2002, the World Green Building Council was officially formed to bring all the GBCs under one roof. [6] GBCs from Australia, Brazil, Canada, India, Japan, Mexico, Spain, and USA were the founding members. [6] As of 2018–19, there are 69 Green Building Councils under the World Green Building Council organization. [8]
