Dear community, we are doing a 90.1 App. G simulation for an existing manufacturing warehouse renovation + office building addition.

I have a project that is using captured rainwater only, no potable water, to supply the irrigation system. However, the credit form does not seem to have this option.

Can anyone tell me if there is a LEED NC credit that would "reward" a project for using Compressed Natural Gas in excavation and other construction equipment?

I am currently working on a project in conjunction with my MBA studies regarding LEED EB certification.

Dear All, I am working on a LEED project in Europe. Our architect is applying several products with Cradle to cradle certificates.

I have to model a heat pump that outside the building exchanges heat with the external air and it exchanges heat with the building, i.e. with the internal part of the HVAC plant, thorough water.

How can I find the evapotranspirtaion rate, ETo, for various plants in various regions, and can this be found on LEEDuser's website?

Does this apply to projects outside continental USA ? And about Alternative Compliance Paths in particular ?
