Hello, If one decides to use option 3 to show compliance with this credit, should the light measurements have to be done in a specific time of the day?

Hello, a question concerning IEQc8.1 & IEQc8.2 . Can we use the net floor area instead of gross floor area for the simulation in Matrix_Table IEQ-1 Daylight and views? I would like to use t

Hi, I have a office project with 2 datacenter floors and I nearly have to submit. My concern is I don't model daylight in NOC room.

I am working on a C&S office building, and I'm reading differing viewpoints on this credit and IEQc8.2. Must these credits be included in the Tenant Lease agreement?

Hi all, In relation to my last comment (below), do folks have good/simple strategies for overlaying their daylight results from Insight (AutoDesk product) to get your compliant SF? Thanks, Hannah

I submitted a simulation output for our core and shell building.

Option1-simulation. The result of ecotect shows the qualified regulary occupied area is 84% at 9 am, 83% at 3 pm.

For LEED 2009 (C&S) is it acceptable to use the following surface reflectances - - Walls -80%, Floors-25%, Ceiling - 80%. Is there any guidance on what can be used for these simulations.

We are pursuing the Option 1 - simulation path. The total regularly occupied area (ROA) reported for the simulation is linked to the PIf3 credit.
