Inquiry

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.
