Ours is an industrial building with 6 overhead doors ranging in size from 16\'x16\' to 20\'W x 25\'H, every elevation has at least one overhead door. It is an operation requirement that while the building is occupied, the overhead doors are open - there would be NO time at which these doors would be closed with staff and/or public in the building. Given this requirement, can we use the door openings in the daylight and views credits 8.1 & 8.2, using a transmittance of 1.0? Thanks.
It is possible that the overhead doors can be used towards the achievement of EQ credits 8.1 and 8.2, though more information is required to positively determine compliance, including: 1. Where is the building located (city and state) and what is the program? 2. In what official policy and/or document is this operational requirement described? 3. Is the building (and space in question) occupied year-round? 4. Are there adjacent offices and work areas that also benefit from the doors? 5. Calculations and vehicle adjacencies as defined in this ruling. By themselves, the doors may or may not achieve the required quantity of daylight factor and views. Calculations demonstrating achievement of the credit are required. Include typical operational factors in these calculations, i.e., if large vehicles, equipment or freight block much of the aperture during the day, these obstructions must be accounted for in daylight and view calculations. The appropriate geometry factors must be included in calculations for both light and views. Please include a letter certifying that the overhead doors are to be open when the building is occupied. Applicable internationally.
