Work was competed last month on the third largest green roof garden located in the city of Washington D.C. the initiative was carried out by WWF – The World Wildlife Fund – on their building as part of their efforts to create a model world home that was good for the environment.
The roof is a pleasure to behold – and ideal space for rooftop parties etc. the original roof of the building was a twenty-four year old one – and the new roof is definitely much more energy efficient.
The new roof ensures that energy waste is minimized and incorporates localized greenery on its surface. This helps to reduce the costs of heating and cooling the building.
The plants on the roof – eleven types of sedum plants – have been obtained from local sources. Sedum plants are well known for possessing water retaining properties.
If more water storing plants are used on rooftops, it would greatly reduce the strain on the sewer infrastructure of the city, which is already reeling under the current volume.
WWF was not alone in getting this dream green roof made. The project received the support of the American Recovery and Reinvestment Act, which gave the organization a grant of $194,250 – that is, seven dollars for every square foot of the green renovation. From removing the old roof, and installing the new one, the project was done in a span of twenty weeks.
