Inquiry

Elimination of Mechanical Air Conditioning It is widely recognized that the ASHRAE 90.1 and Title 24 energy codes are designed for compliance and do not always allow project teams to report a complete picture of their efforts to conserve energy. An example would be a building designed without air conditioning. The energy modeling software approved for ASHRAE and Title 24 requires that systems in the baseline building match the as-designed systems. Usually, a project can get credit for using more efficient systems but not for eliminating systems completely. We have eliminated air conditioning in a major portion of our building by going to natural ventilation. We propose to demonstrate that removing mechanical air conditioning from this space will reduce our energy cost by at least 5% over the conditioned alternative and to apply for an Innovation Credit, since this effort is not rewarded in the energy model for EACr1. Is this an acceptable approach to an Innovation Point?
