keep occupants comfortable and reduce heating and cooling costs;

Unvegetated roofs have light-colored, high albedo, or highly reflective, surfaces that absorb less heat from sunlight and reduce energy costs.

• Insulate buildings from sound; • Increase the property value and marketability of buildings;

Extensive Green Roofs

• Beautify the urban landscape;

Intercept rainfall, filter air and water, lower the heat island effect, and provide habitable space

• Create greenspace and physical respite for people; • Provide habitat for wildlife, including migratory birds; • Absorb noise and pollution;
