Building Sciences: Seeing Red Over Green Roofs
Its not that the author has anything against green roofs, he likes them just fine for their aesthetics and, because ugliness in buildings is not sustainable. However, he thinks many are being misled by the purported environmental benefits because they are more expensive than any other option and, they dont save energy compared to an otherwise well-insulated roof.Citation: ASHRAE Journal, vol. 53, no. 6, June 2011
