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?
