This project is a high rise mixed-use office building pursuing LEED Core & Shell certification with no or limited tenant build-out plans. For IEQ8.1 and 8.2, how do you: 1) calculate Window Area for continuous curtain wall for an open floor plan (no interior rooms) and 2) calculate the floor area (no interior rooms)? Is it from the perimeter curtain wall back to the core? Thanks.

The window area is the area of glazing between the frame that starts 30 inches above the floor to the head window head height.
The floor area is calculated from the window wall to the core.

Thanks Todd. For example, on an open floor plan with continuous glazing along the west façade, I would take the window height (30" above floor) x the length of the building and divide by the floor area which would be equal to the length of the building x the distance back to the core? Secondly, for 8.2: Views, I read in the forum I need to submit tenant plans, which I don't have for unleased floors. How should I manage that? If I don't have tenant plans for open floors, there appears to be 100% views. Please advise.

Maggie,
I assume you are attempting the prescriptive method? You are correct with how to calculate the window area. In regards to floor area: for each orientation, draw a line from the exterior corner of the building to the corner of the core dividing the floor plate into four parts. That polygon is the area to calculate your floor area for each orientation.
EQc8.2, you do not need to submit the actual tenant plans, just a proposed tenant layout. So based on the proposed occupancy number, put x amount of desks per floor. This would be calculated by the proposed occupancy divided by the number of floors.
