Green Roofs Everywhere!

Every government building should have a green roof - this will not only be a beautification project, but can also significantly cut down on energy usage.

 

From the Wikipedia (http://en.wikipedia.org/wiki/Green_roof) entry:

 

-Reduce heating (by adding mass and thermal resistance value)

-Reduce heat loss and energy consumption in winter conditions.

-Reduce cooling (by evaporative cooling) loads on a building by fifty to ninety percent

especially if it is glassed in so as to act as a terrarium and passive solar heat reservoir — a concentration of green roofs in an urban area can even reduce the city's average temperatures during the summer

-Reduce stormwater run off— see water-wise gardening

Natural Habitat Creation — see urban wilderness

-Filter pollutants and carbon dioxide out of the air which helps lower disease rates such as asthma

-Filter pollutants and heavy metals out of rainwater

-Help to insulate a building for sound; the soil helps to block lower frequencies and the plants block higher frequencies

If installed correctly many living roofs can contribute to LEED points

-Agricultural space
