Inquiry

Our project is a 238,000 SF brick manufacturing facility in Terre Haute, Indiana. The project consists of 5,000 SF of office space and 233,000 SF of manufacturing area, including extrusion, drying, and kiln equipment. The requirement for INTERIOR LIGHTING indicates "The angle of maximum candela from each interior luminaire as located in the building shall intersect opaque building interior surfaces and not exit out through the windows." This would indicate that light other than that emitted by the angle of maximum candela would be allowed to exit thru non-opaque surfaces. Our building design includes diffuse translucent panels along the perimeter walls which allow 40% transmission of light through them. The angle of maximum candela does intersect these translucent surfaces, but the light is diffused by the panels. Even at the angle of maximum candela, any interior light passing through to the exterior is substantially reduced. Please verify that this meets the intent of the credit by minimizing light trespass from the building.
