France’s law on green or solar roofs for new commercial buildings

FRENCH LAW TO REQUIRE GREEN ROOFS OR SOLAR PANELS ON NEW COMMERCIAL BUILDINGS, ecosalon, by  on March 24, 2015 France just passed a new law that will require all new buildings in commercial zones to be covered with green roofs or solar panels.

Environmental groups hope to reduce the energy costs of commercial buildings while creating an urban jungle in the world’s most beloved city of progress…..The law will change the face of the urban landscape in France by promoting more urban greenery.

While solar panels have an obvious purpose, the benefits of green roofsare less well known. Not only do they beautify buildings and create space for community gardens, they have a number of other environmental benefits.

In the summer, green roofs retain 70 to 90 percent of precipitation and in the winter they retain 25 to 40 percent of precipitation. This reduces runoff and decreases the stress on sewer systems. The daily dew and evaporation cycle along with the light absorbed by vegetation, help to cool buildings down. Green roofs also reduce smog by slowing the distribution of dust and particulate matter……..

The combination of solar panels and green roofs create dual environmental tools. Both help reduce the power demands on the national grid, especially when temperatures peak in the summer time.

Green roofs are popular in Germany, Australia, and parts of Canada. Since 2009, Toronto has had a similar mandatory law for green roofs on commercial buildings. But they’re also gaining traction in the U.S. New York City leads the pack in green roofs and it’s home to the largest roof top garden in the country. James Farley Post Office is topped with a greening system that saves the massive post office $30,000 per year in energy costs. Chicago, Washington, D.C., and Portland are all home to a number of green roofs.http://ecosalon.com/french-law-to-require-green-roofs-or-solar-panels-on-new-commercial-buildings/

  1. Waterproofing aside Gardens on roof in this UN year of soil need serious science input. 1st only 2-4% of plants sequester CO2e to soil hence nutrients and soil renewing. 2nd 96% of bushes trees take biomass carbon from soil and what CO2 it takes in during the day emit such at night. High rise buildings around such gardens could have high atmospheric emissions and a case at law. Best the Government takes advice and can see results by December UN assembly. Robert Vincin
