Inquiry

Our project is a 140,000 SF hospital building that includes a three-story 37,000 SF Medical Office Building (MOB) integrated into the overall building footprint. The MOB shares a wing of the hospital with the Administration and Conference Center. The mechanical systems of the hospital and the MOB are connected in that the hot and cold water (both domestic and heating) come from the hospital to serve the MOB. Normal and emergency electrical power and the low voltage services come from the hospital to serve the MOB; and the process cooling water also originates in the hospital to serve the MOB. There are two air handlers on the roof of the MOB; one of which serves the hospital/admin building. For all parking and stormwater calculations the MOB and hospital have been combined into one \'building.\'\n\nBased on current scheduling projections, the tenant improvements in the MOB will not be completely built-out when the hospital is completed. As the MOB is an integral part of the hospital, all components of the core and shell of the MOB have been designed to meet all LEED prerequisites. To that end, the MOB has also been included in the energy model and commissioning work, and will be accounted for in all site, water, energy, materials and indoor environmental quality credits where applicable.\n\nThe only credits that we are attempting that will be affected by the later interior build-out of the MOB are MRc2, MRc4, MRc5, EQc4.1, EQc4.2, and EQc4.3. In comparison to the total amount of materials used for the overall project (including site-works, the hospital and MOB core and shell) for MRc2, MRc4 and MRc5, the materials used in the later MOB built-out will be a very small percentage. Based on this, we propose to exclude any incomplete interior build-out work from the LEED submission, as we intent to submit once the hospital is completed.\n\nThe tenants will be required to meet LEED credit requirements for EQc4.1, EQc4.2 and EQc4.3 in regards to the future build-out work. All tenant improvements that have been built-out at the completion of the hospital will be included in the LEED submission.\n\nWe would like to confirm that this approach is acceptable for LEED submission, and meeting the LEED requirements for certification.
