NC-2009 IEQp1:Minimum IAQ Performance

Alternative Compliance in lieu of LEED Tables

Has anyone been successful using the alternative compliance path and submitting their own ASHRAE 62.1 calculation/spreadsheets in lieu of using the built in LEED or 62MZCalc form? We would rather save time by not re-entering a ton of info and just provide a narrative and our calcs to prove we meet ASHRAE 62.1.

While we have not submitted our own EQp1 calculations in lieu of the 62MZ we have been told by GBCI that non-62MZ calculations are acceptable. As always, provide a detailed narrative explaining your methodology.

I think that it is unlikely that the LEED reviewer will accept your own spreadsheet. They provide a spreadsheet for you to use. I think it would take longer for you to convince them that you calculated multiple zones with unused OA correctly than it would to just fill out their spreadsheet. I recommend using the provided 62MZcalc.
