I’m working on a Project in Portugal, which consists in a 13.400m2 site, with 6000m2 rooftop (harvests rain), 2500m2 green roof, 2735m2 of gardens, 306 m2 of planters and 1840m2 of impermeable pave

Our building is connected to a public rainwater channel which is placed out of the LEED boundary, the rainwater channel is connected to the sea.

Our project is harvesting and reusing rainwater for flushing. rainwater that falls on the roof is collected in a 10cubic meter sump.

The Design Team for an urban office bldg. proposes to collect water from roof and terraces as well as mech. condensate for reuse (in irrigation and cooling tower make-up water).

If local requirements are not as stringent as LEED requirements, are we still required to meet LEED requirements beyond local standards?

Can we eliminate site area to be dedicated for the computations for 1" of rainfall? i.e. existing site area is 5 acres witih a 1" volume of 14,000 cf.

For table SSC6.2-1, we dont know how to describe BMP neither its TSS removal efficiency, because the rain water from the parking is directed and collected to be sent to a vegetated site outside the

use of lead metal downspouts in stormwater systems does LEED NC v2009 (v3) prohibit the use of lead based metals?

Hello, I would like to get confirmation on whether the following approach of demonstrating compliance with LEED requirements could be accepted or not.
