Our project is a 75,348 sf existing 2-story office building to be renovated and constructed to achieve LEED NC2.2 certification. Tenant #1 will occupy more than 50% in the initial buildout, thereby establishing the project as a Major Renovation under LEED NC. The balance of the building will eventually be occupied by a second tenant, not yet identified. The HVAC system will be installed for Tenant #1, but not for Tenant #2. It is our intention to perform the Energy Model as though the entire building will be air conditioned although the actual equipment will not be installed for Tenant #2 initially. Documentation will be provided including lease agreements verifying that 100% of the leased square footage complies with LEED requirements and a statement signed by the Owner verifying that all lease agreements will comply with the Tenant Guidelines. The Tenant Guidelines will establish the lighting power density, minimum HVAC efficiencies, etc. Additionally a letter from the Owner outlining requirements exceeding ASHRAE 90.1-2004 will be provided to future tenants and will be strictly enforced. We seek confirmation that the approach we propose will be acceptable for LEED NC2.2 certification of the building without the remaining Tenant Space #2 being occupied, provided sufficient LEED credits are earned.
The applicant is requesting approval to model tenant fit-out portions of the building with identical HVAC systems, lighting power densities (LPDs), etc. to the occupied portion of the proposed building. No HVAC, lighting, etc. system will be provided for the tenant fit-out portions of the building prior to LEED certification. Therefore, energy simulation parameters for these spaces are not known and need to be documented very specifically in the \'tenant lease agreement\' and not just be general. Specifics should include all of the following - system type, equipment efficiency, controls, system capacity and square foot load assumptions. The tenant fit-out portions of the proposed building should be modeled using baseline parameters and methods specified in ASHRAE 90.1-2004 Appendix G. Please note, however, that the parameters of any installed components (e.g., building envelope, shading, etc.) that are within the scope of the building construction may be modeled using the parameters shown on design drawings. In order to document this approach, the project team should provide a narrative which clearly identifies what portion of the building will not be occupied by the owner and what parameters in the tenant fit-out portion will be modeled according to the design drawings. The LEED submittal template should include both the proposed case parameters and systems that correspond to the owner occupied space and the tenant fit-out space.
