Yes, I agree that i should use the existing envelope for the existing conditions of the existing building and the ASHRAE Min for the new building. But it comes down to whether EA Credit 1 follows the new building % or the existing building %. it is a 2 point difference that could effect strategies for saving energy later in the design.<div>
