The base building project is a new shell and core office tower of approximately 1.4 million gross square feet and 46 occupied floors. The building owner intends to only occupy approximately half of the total building general office space square footage, with the remaining tower floors and retail space available for future third party tenants. For this reason the LEED scope was defined to appropriately address these project parameters and registered under the guidelines: 1.LEED for Core and Shell Development v2.0 - Owner of Office Tower/Base Building 2.LEED for Commercial Interiors v2.0 - Owner occupied half of the tower general office space Can known tenant area building efficiencies associated with the owner occupied spaces be accounted for in the Core & Shell submission? The "Core and Shell Energy Modeling Guidelines" section of the Core & Shell reference guide states in subsection 2.2.1.2, "If tenant lighting is designed and installed as part of the core and shell work, the project team may model the designed or installed lighting systems." This has been interpreted to credit the Core & Shell submittal, and subsequently the owner, for designing the owner occupied spaces in concert with the base building. For our project, the same design team has designed both the owner occupied tenant spaces and the base building, and thus is more similar to a NC project for this portion of the project. Please confirm that the proposed model could include the As-Designed lighting systems throughout all C/S spaces and owner occupied tenant spaces, while the basecase building would include ASHRAE 90.1-2004 thresholds for all spaces. As an extension of this intent, please confirm building efficiency measures targeted at the owner occupied tenant plug and process loads (in particular, the high performance data center), can be accounted for in the C&S submittal. Assuming well documented baseline and as-designed conditions, please confirm that the proposed model could include equipment power calculated from the high performance data center and plug load data, while the basecase model would include equipment power calculated from the baseline data center and plug load data. An NC submittal would allow credit to be taken for the high performance data center, while the Commercial Interior submittal does not allow credit to be taken. The high performance data center will provide significant energy savings that the design team would not like to have lost in the LEED process. Similarly, can building energy savings due to daylighting be accounted for in the Core & Shell submittal? Daylighting energy savings are a product of daylighting systems and lighting controls. For this project, all daylighting systems are designed for all spaces, they are integral to the shell, and furthermore, are included in the base building or Core & Shell budget. All owner occupied spaces have daylight photosensors, while it is planned for tenant spaces to be contractually required to utilize daylight photosensors upon interior build out. Please confirm that the proposed model could include the daylighting impact on the As-Designed or ASHRAE 90.1-2004 lighting systems throughout all owner occupied and non-occupied tenant spaces, while the basecase building would include no impact from daylighting.
