Too many measurements!

NC-2009 IEQc8.1: Daylight and views - daylight
posted by Eric Shamp on Jan 31, 2012, 12:54 pm

I'm working on a skylit warehouse, around 700k sf. We're just barely non-compliant using Option 2 Prescriptive (something like 2.8% skylight area), but spot checks show that we'd be compliant...

IEQ 8.1- Option 3

posted by Truex Cullins on Jan 24, 2012, 3:20 pm

Does the measurement for this credit have to be performed by some certified, un-biased 3rd party? Or can the contractor/architect/engineer/owner perform the test?
Thanks in advance for any...

Dear All,

What are the requirements of daylighting in a residential building? Specifically:

(1) Are bedrooms included in the calculations? The Reference Guide states that regularly...

Daylight Simulation Methodology

posted by Omer Moltay on Apr 15, 2010, 6:39 pm

I am a bit confused about the daylight simulation. We have carried out simulations for every occupied space in the building at 09:00 AM and 15:00 PM. We take the percentage of areas that are...

10 fc or 25 fc?!!

TODD REED Energy Program Specialist PA DMVA LEEDuser Expert 892 thumbs up January 24, 2012- 11:51 am The last addenda issued by USGBC changed the minimum requirement to 10fc. This is only noted in the addenda so Reference Guides will not show this. I assume the 25fc minimum you have seen in the forums and the threads were prior to this addenda.

I'm trying to decide whether to continue pursuing Option 3 measurements. December in the northeast is not an ideal time to be measuring daylight, even when it's sunny outside. The footcandle...

application of daylighting and human perception mechanisms. If I had my way, this forum would not be used for specific questions about daylighting simulation because it implies that these software programs are easy and complete ways to evaluate daylighting and they are not. The questions for daylighting simulations would be best discussed on each software's forum, through IBSPA or the building simulation forum. Email me if you would like the addresses to any of these forums.
