Hi John,
Please show me the data that shows a typical payback on a green roof is 50 years.
There are so many factors to this that disputing the effects of a green roof right before throwing out your own data makes your initial statement unbelievable

Editor’s note: Turner Construction Co. clarified the cost savings from the green roof at closer to 20-30 percent.

This is a lot of hooey. NO green roof EVER saved anywhere near 75% of a building’s air conditioning costs…… if this were true, everyone would have one (a green roof) already. Typical payback on a green roof is 50 years. There are far better ways to save money on HVAC costs than putting on a green roof.
