NC-2009 IEQc8.1:Daylight and Views—Daylight

IEQ 8.1 - Option 3

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 replies.

Matthew, It's actually a simple measurement. There is no requirement who should conduct the measurement in LEED. Thus, anyone who knows can do the measurement.

Thank you Eddy. One other question: When attempting Option 3, does the same rule from Option 2 apply where if 75% or more of the space complies then 100% of the area may be calculated? For example: If there are 4 readings in a room, 3 are compliant and one is below 10fc, then does the entire space 'pass'? If not, then how does one calculate the portion of the area that does pass?

No. And actually, I believe the 75/100 rule only applies to the Views calculation? If there are 4 readings in a room and 3 of them are compliant, 75% of the area of the room gets added to the compliant area. You don't pass/fail based on rooms, you pass/fail based on % of compliant area to total are of ROS.

The 75/100 rule applies for private office spaces only for view credit.
