Abstract A green roofis a vegetative layer grown on a rooftop. Green roofs remove heat from the air through the process of evapotranspiration, and also act as insulators for buildings, reducing the energy needed to provide cooling and heating. Using green roofs in cities or other built environments with limited vegetation can moderate the heat island effect, particularly during the day. Green roofs can reduce building energy use compared to conventional roofs, reducing peak electricity demand. Green roofs provide aesthetic value and habitat for plant and animal species. Shade trees offer significant benefits in reducing building air-conditioning demand and improving urban air quality by reducing smog.The right tree in the right place provides wind protection, shade, and cool air, while adding beauty, privacy, and wildlife habitat to the landscape |
