We have a 31 storey office tower under construction and slated for substantial in October 2017. It was designed and construction started without any confirmed tenants. At this point in the process, a hotel is negotiating with the owner to lease the bottom 11 floors and will have started construction prior to completion of the core building. Generally for C&S projects tenant impact is not controllable and is understood to be that way. However this represents quite a different use than what was designed which has an impact on occupancy, energy and water use. What are the implications, if any, for certification of the C&S building with this unexpected tenant use?

Did you use CS Appendix 1 (LEED Reference Guide page 611) to generate your default occupancy counts initially? Assume you used general office gross sf per occupant and are now looking at hotel? You will likely find that your employee numbers will be reduced but your transient numbers will increase. In general as much information as can be provided about building use should be included in the CS certification. Have you already submitted CS credits to GBCI for review?

Thank you Summer. We did use the default occupancy counts and you are correct we will now see changes in occupancy as you noted. We have already submitted CS credits for Design Review. That process is now complete. I am assuming then that we will need to update all affected credits for Construction Review.

Yes. In addition I would write a detailed narrative for GBCI reviewers that clearly explains the changes made and how they have been reflected consistently throughout your documentation. Good luck!
