Inquiry

For an elementary school project registered under NC 2.1, we are targeting EQ 8.1 and can demonstrate that some regularly occupied spaces meet the daylighting requirement using the calculator/formula in the reference guide, but some do not. The spaces that don\'t comply test well using a light meter. My questions are: 1.) Is it permissable to demonstrate credit compliance using a hybrid approach: The calculation/formula in spaces where that demonstrates compliance and actual measurements where it does not? 2.) What is the correct and prescribed procedure for taking measurements? The reference guide does not provide one. I\'m assuming clear sky conditions and measuring with a light meter on the same size grid required for daylight modeling are part of the protocol - what else? Is the procedure described anywhere? Can you provide the referenced standard for testing or a description of the procedure?
