NC-2009 IEQc8.1:Daylight and Views—Daylight

Room by room versus Apartment calculations

Our project is a 14-floor residential project. We are pursuing the prescriptive pathway for daylighting, which requires us to calculate the floor to window ratios for each room. However, we have already prepared documentation for views on a per-apartment basis. Would it be acceptable to complete two versions of the USGBC-provided Supplemental Daylight and Views Calculation Spreadsheet for documentation of IEQc8.1 on a per-room basis and IEQc8.2 on a per-apartment basis? Does anyone have experience submitting like this?

It would be acceptable to provide two different calculators. I believe you will have an issue because when you upload the calculator in one credit, it is automatically linked to the other. You will have to upload the other calculator in the other document section of the credit, I believe. I would suggest that you provide a narrative explaining what you are doing so that the reviewer knows that there are two different calculators provided. I would also suggest that for your views credit that you also provide individual apartment view calcs on a room by room basis. So for each different type of apartment, provide a separate sheet showing how the overall apt value is calculated. You can then just upload the by apt calculator.
