Hello, I'm trying to get IEQ C8.1 by the prescriptive option, but I'm having problems with the calculation of the visible light transmittance. Inside of the same space I have an outer glass facad

Hello, We would like to clarify some questions regarding the credit EQc8.1 – Daylighting for buildings pursuing LEED 2009 Core&Shell certification in Brazil.

LEED reference guide said that in Option 1 compliance should be demonstrated through computer simulation of all regularly occupied spaces.

Hello there! Based on the Reference Guide Correction ID#100001102 made on 11/01/2011: "Non-regularly occupied spaces are spaces that occupants pass through, or spaces used in pursuit of focused a

Hi, I'm working on the building that on the ground floor has an entrance lobbby with a desk for receptionist and some retail space. On the upper floors we have an office space.

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.
