Hi everyone! We are working on previously undeveloped land project, which apply for case 1 “site with existing imperviousness 50% or less”.

I'm working on a project where the existing site is 100% concrete paving. We are not providing any landscape, thus no irrigation. Does this mean we comply with option 2?

Is rockwool considered a rapidly renewable material? I understand that rapidly renewable materials must be made from either plants or animals and must have a harvest cycle of 10 years or less.

I am working on a project where we are doing TI work on two different flloors, of the same building, for the same tenant. Can this be treated as 1 project for CI 2009 certification purposes?

Hello, We have a previously developed project that does not meet the site area for protect and restore habitat.

We are working on a project that consists of 2 buildings: office building and workshop building.

I'm working on a project containing one Basement, Ground and a first floor, it is a residential building, its building footprint meets the minimum program requirement.

It seems that scop of CS does not require CO2 sensors to be placed in tanent space.

Our system has fan-powered VAV boxes. The first review comments required us to use 62MZ calc to account for local recirculation. But we have 120 AHUs and hundreds of zones.

The Owner dragged his feet and did not bring a Commissioning Agent on board until after the construction documents were complete, and construction started.
