I submitted a simulation output for our core and shell building. We included the modeled floor plans with simulation shown on them, tables that show both 9am and 3pm results for each room, and additional table that selected the worst case amount of SF from each room (of the 9am and 3pm results) to show that we were compliant. We received feedback from our Design review that says:
The information entered in the LEED Supplemental Daylight and Views Calculation Spreadsheet does not appear to accurately reﬂect the results of the daylight simulation model. The simulation output document only indicates the compliant areas for 9 a.m. and 3 p.m. individually, and the lower value has been used as the total compliant area, which is not the correct calculation methodology. Revise the spreadsheet to ensure that only the area that is compliant at BOTH [emphasis added] 9 a.m. and 3 p.m. on September 21st, not at one time or the other and not the average compliant area, has been reported as meeting the daylight requirements. Provide revised output reports from the daylight computer simulations and/or a narrative, as necessary.
The information that I provided was actually the WORST CASE of each - this was summarized in the spreadsheet for them. Do we think they're just ignoring that worst-case information I provided, or do I need to figure out how to model something that shows ONLY the square footages that overlap as being sufficiently daylight at BOTH 9am and 3pm? I was under the impression that the way I calculated (which seems to be the way that is suggested above) was correct, but I could be wrong. Is this a new requirement or am I totally off base?
