We would like to submit a CIR to request a streamlined approach for the daylight documentation. We have the particular condition of an identical cluster of office buildings. In spite of having the same foot print, each building will be uniquely impacted by orientation variation and specific surrounding context condition. The intent is to fully document one building showing that the amount of light increases as you move up through the floor plates. Then to proceed to document the worst case scenario of each building (ground floor) or the level that is least exposed to solar access. If the worst case scenario passes, then we infer based on our test case that the upper floors of the building will pass as well. This will help us streamline not only the documentation process for so many buildings but also the review process. Is this an acceptable documentation method for this credit?
The project team is requesting whether a campus credit may be pursued for IEQc8.1. Daylight and Views: Daylight through a typical floor plan and worst case scenario daylight calculations.
Yes, the typical floor plan and worst-case scenario daylight calculations may be used for the campus credit and applied to all buildings within the master site that have identical floor plans.
The 2010 Application Guide for Multiple Buildings and On-Campus Projects identifies IEQc8.1 as an individual building credit and states that each building should pursue the credit individually. However, in the same way that a multi-story building may provide a single floor plan for each grouping of identical floors, if buildings within the Master Site are identical, the same documentation may be used for each identical building.
Any of the calculation methods (simulation, prescriptive, measurement) may be used. Documentation for the campus credit and associated projects must demonstrate how the worst case scenario was determined and that the only difference in the buildings is the orientation on the site. The footprint, square footage and interior layout of the buildings must be identical.
