Hello, We are pursuing the Prescriptive Method for this credit, using both skylights and windows.

For a project that has multiple typical floors and a large area, is it allowable to simulate a typical floor and just multiply the non/daylit areas for documentation?

Dear All, I am using Daylighting module of Design Builder V3 for IEQc8.1 daylight calculations and it gives very different results (less light) than the calculations conducted with Ecotect+Radianc

We have some projects in which regularly occupied spaces are designed with no-windows because of client's requirements. These are process areas (a kitchen and a laboratory).

Dear all, I'm now working on a project (office building, new construction) under LEED NC v2009 Certification.

Hello- I don't know if anyone has asked this question or not, it is a rather unique situation.

Does anyone have a copy of the Calculation Spreadsheet that does not require the use of macros.

I've downloaded the Supplemental Daylight and Views Calculation Spreadsheet from my registered LEED for Schools project, but have not been able to get into it and input data.

We have few interior rooms on our project that “borrow” daylight through relites facing exterior window.
