The project in question will be a core & shell warehouse building. The first sixty feet inside the loading dock doors is considered a staging area. Due to the nature of this space, this area will remain an open area, without walls or storage racks, regardless of the tenant layout. Our core & shell warehouse project developer/owner proposes to install skylights in the perimeter zone (staging area) of the facility to afford the tenant daylighting in the loading areas of the facility. In addition, the developer/owner will install a daylighting control system with photosensors (minimum one per perimeter zone and tenant) in the core & shell facility. Tenant design guidelines will require that the tenant connect their installed lighting in these perimeter zones to the daylighting control system. Appendix G of ASHRAE 90.1-2004 states that the proposed case may take advantage of daylighting controls when installed. The ambiguity and thus our question lies in the case when the tenant will install the lighting but the owner has provided both a building envelope congruent with interior daylighting design strategies and a control system that will reduce electric lighting automatically due to the available daylight. With regards to Energy & Atmosphere Credit 1, Appendix G of ASHRAE 90.1-2004 and a core & shell building, can the proposed case energy model account for the electric lighting savings (lighting designed and installed by the tenant) that result from use of daylighting controls (provided by the owner) in conjunction with the installed skylights (provided by the owner)? In our model, the savings and skylights will be restricted to perimeter zones only.
