Hi My project is having green roof (less than 50 % of the total roof area though) and the rest of the roof area will be covered of solar cells. Can I somehow use this toward this credti?

A very interesting question and to answer it will take a lot of space. 1. Why are you only doing one? 2. Are these existing buildings or half in construction? 1.

The link to the LEED LCA Credit Calculator does not appear to be working anymore.

I am trying to determine the R-values required for a project - a major renovation to a 1940's existing building. The building structure is steel beams and columns, encased in concrete.

Rule 1113 was amended on June 3rd 2011 and now the limit for clear wood varnish is 275. I assume updates to Rule 1113 apply to LEED. Is this correct? 

A large amount of carpet was donated to us by a big local company who didn't use it all in their hotels. The carpet itself had never been used.
