Green buildings: not so expensive

A study sponsored by the investment firm Good Energies on 150 green building projects around the world shows that, on average, they cost only around 2% more than traditional buildings and yielded 33% savings on energy use. These results can counter the idea that green building is too expensive since a 2007 survey from the World Business Council for Sustainable Development, for example, reported that business leaders believed green buildings would cost 17% more than traditional buildings.
