Inquiry

Our project is a core and shell 6 story office building. The project was registered after June 29, 2007, and, therefore is required to meet 14% energy savings over the baseline building performance. Currently, our energy model reflects a proposed design of 12% improvement. Unfortunately, we cannot make any modifications to the mechanical design or building envelope at this point in the project. The last option to meet the new requirement is to include lighting efficiencies in the tenant space by specifying and requiring that tenants design not to exceed 1.10 watts/sqft (which brings the overall project above 14% for the proposed building performance) This requirement will be stipulated in the lease with the proper verification process approval by the owner before each tenant improvement is submitted to the Building Department. If all the tenant improvements specifications require the lighting to be designed not to exceed 1.10 watts/sqft., can we include the tenant space in the model to allow us to meet the new 14% requirement?
