Green Roof Energy Savings Studies

Green roofs and energy performance.

Green roof energy savings studies.

This paper reviews the current literature and highlights the situations in which the greatest building energy savings can be made. Many studies have been conducted over the past 10 years to consider the potential building energy benefits of green roofs and shown that they can offer benefits in winter heating reduction as well as summer cooling. The study looked at a range of benefits of green roofs including stormwater management improved health benefits due to reduced pollution and energy savings. This suggests that green roofs are predominately seen as a passive cooling technique rather than as a thermal insulator in the winter.

Over its estimated lifespan of 40 years a green roof would save about 200 000 of which nearly two thirds would come from reduced energy costs. Green roofs benefits improved energy performance temperature of waterproofing membranes under green roofs. Green roofs benefits include. Nearly two thirds of these savings would come from reduced.

Studies have shown that the membrane temperature beneath a. A university of michigan study showed that more than 50 percent of the cost associated with installing a green roof will be returned in the form of lower maintenance and reduced energy usage over the lifetime of the green roof system. 4 undertake economic assessment of the developed green roof. In the first part of the study the authors present an overview of green roof technology an insight to energy and environmental challenges in saudi arabia and the green roof model development and validation.

3 determine the energy saving potential of different green roof options.
