Green Roof Energy Savings Studies

Green roofs are a passive cooling technique that stop incoming solar radiation from reaching the building structure below.

Green roof energy savings studies.

Green roofs do provide potential energy savings by improving building insulation. 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 paper reviews the current literature and highlights the situations in which the greatest building energy savings can be made. This suggests that green roofs are predominately seen as a passive cooling technique rather than as a thermal insulator in the winter.

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. 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. 3 determine the energy saving potential of different green roof options. Nearly two thirds of these savings would come from reduced.

Many studies exist that assess the potential energy savings of green roofs when added to buildings but it should be noted that these are predominantly for warmer climates than the uk. Studies have shown that the membrane temperature beneath a. Green roofs benefits improved energy performance temperature of waterproofing membranes under green roofs. 4 undertake economic assessment of the developed green roof.

Green roofs benefits include.
