We are pursing certification of Japanese company's headquarter office. Our project building has both air-cooled heat pump system and geothermal heat pump system with many bore holes that collect heat in winter and reject heat in summer. It does not include a cooling tower and does not use the latent heat of the evaporative cooling of water. Additionally, the project does not receive any cooling from a District cooling system. The baseline system designated by ASHRAE 90.1-2010 Appendix G Table G3.1.1 is system 7.

Our concern is that the demonstration of the above will be sufficient to achieve the documentation requirements for the credit. Does anyone answer our question?

Hello Noriko, You can apply for the No Cooling Tower pilot alternative compliance path. You need to include the following as part of the submittals: a. A copy of the Pilot Credit registration confirmation email b. A copy of the Pilot Credit survey confirmation email c. Documentation showing that the project is designated as systems 7 or 8 under ASHRAE 90.1-2010 Appendix G Table G3.1.1 d. Documentation (site plan or mechanical system plan, energy model or other) showing that the project design case does not include a cooling tower or other system that uses the latent heat of the evaporative cooling of water, and is not connected to a District cooling system. This should help you to meet the requirement with this approach. Hope it helps!
