Hello,
we are working on the project of a new commercial building where green roof is about 50 % of the whole roof.
There are some HVAC installations consisting of a mechanical part (located on the non green roof) and of a ductwork (located mostly above green roof and partially above non green roof).
How can we handle this situation? Should we deduct all the HVAC installations of the roof area OR should we deduct the mechanical parts only? What do do with the ductworks above the green area?
We would prefer to deduct all the HVAC or to deduct mechanical parts only for reduction of a roof area. Is it correct?
Thanks for any advice.
Petr

You can deduct both the equipment and the duct work. see also the definition of roof area: http://www.leeduser.com/credit/NC-2009/SSc7.2#comment-16498
In many countries you are required to have gravel strips around and under equipment for fire security and people safety reasons. Even thought I don't think that was the reason for excluding these areas.
Good luck with the project.
