CS-v4.1 EQc5:Quality Views

Aligning Regularly Occupied Areas Between Daylight and Views Credits

In LEED CSv4, the daylight credit assumes that the entire floor plate excluding the core is considered regularly occupied area. Taken from the 'Rating System Variation' section on page 735 of the reference guide:

Core and Shell
Project teams may assume surface reflectance for finishes in unfinished spaces as described in the credit
requirements. Project teams must assume that all spaces except the core and restrooms are regularly occupied. In
unfinished spaces, permanent interior obstructions may be excluded from the analysis.

The views credit has a different requirement for the floorplate. Taken from the 'Rating System Variation' section on page 753: 

Core and Shell
Develop a feasible tenant layout based on default occupancy (or other justifiable occupancy count) for use in
analysis of quality views. Layouts should reflect the anticipated use of the unfinished spaces.

To me, there is an apparent contridiction between these two requirements and the general requirement to keep the regularly occupied areas consistent across credits (which will include the ventilation credit in addition to daylight and views). Is there some guidance on how to reconcile the areas and the requirements for each?

Hello Elliot,  This is a really good question. I asked GBCI this, and here is the response from their internal Daylight / Views expert: It is correct that Quality Views uses a feasible tenant layout, whereas the Daylight credit does not (same as in v2009). If the Core & Shell building wants to model the Daylight credit using a proposed layout (or final tenant layout if they have it already), that would be more restrictive than modeling an open floor plate; so that would be fine. Hope this helps!

Thanks for the response, David. It makes sense and this is the way we have approached it in the past, although one could make the case that using the tenant fit out on the daylight is less restrictive than the blank space, because it can allow areas deep in the floorplate that will likely be underlit such as around the zone around the core to be deducted as circulation space. I also think I answered the other part of my question with a deeper dive into the Reference Guide and LEED Space Matrix. Daylight and Views are the only credits that reference regularly occupied spaces (the other ones reference occupied spaces, of which regularly occupied and nonregularly occupied are a subset) and therefore the only ones that need to maintain consistency.
