Healthcare-v2009 IEQc8.2:Daylight and views - views

Projects with basements

I am working on a Clinic that has one basement floor entirely below grade. There are no inpatient areas in this project so we only need to comply with the Non inpatient portion of the credit that gives a perimeter area threshold per floor plate. From looking at the Reference Guide, my understanding is that this project cannot meet the requirements for the credit since the basement floor plate will not have any windows to provide views in the perimeter areas and the credit is based on the worst performing floor plate, even though there is an additional 400,000 sq ft of clinic space spread over 4 floors above grade that complies with flying colors. Could someone tell me if I am correct? It seems to me that there should be some sort of calculation that averages the areas of perimeter spaces with views, otherwise any project that has the tiniest fraction of the building completely below grade will not comply. Also, the calculations section of the reference guide gets into some semantics about "qualifying walls" in regards to below grade walls but is pretty vague and confusing as to whether the basement has no qualifying walls and therefore is an exception, or just does not meet the credit requirements.

Shannon I agree with you on the lack of guidance on basement floors and would love additional information or examples. I'm dealing with the same thing on a project where the radiology lin accs, PET scanners, MRI, CTs are all in the basement and are located along the outside walls to reduce radiation exposure, wall depths, etc. At the same time, I feel for the staff who have to work down there and think we should be better about light wells. The way I read the credit (and I may be wrong here) is that the whole project is averaged out over the entire building for (1) perimeter rooms and (2) qualifying rooms. However, assuming that your 4 stories are over just the 1 story and all of the 4 stories qualify and there are no 'unqualified' rooms taken out, your project will be screwed if there are any occupied spaces below grade spaces. You're not likely to have that 10% offset from the above grade areas to apply to your below grade level until the building is over 9 or 10 stories tall. I hope that makes sense. Here's hoping someone from GBCI will read this thread and provide an assist. Then there is the direct link between IEQc8.2 and IEc8.1!

Hello, I have the same question regarding below grade levels which have regularly occupied spaces, do you have any update since your last post in 2013? If we refer to the excel sheet "HC Supplemental Daylight and Views Calculation Spreadsheet", it is specifically mentioned in the header of this spreadsheet that we should "Exclude below grade levels", Can someone confirm that below grade levels should not be counted in the IEQc8.1 / IEQc8.2 calculation? Thank you
