I have a new office building where all space heating is designed to be electric heat pumps with supplemental electric resistance, including the outdoor air makup units using heat pumps. The project is a large office, >150,000 sf, and I believe my baseline system type would System Type 8, VAV with PFP Boxes. On the project, I do have domestic hot water and a kitchen using gas, as well as a process-hot water system for snow melt. Would any of these gas systems impact the baseline heating fuel type?
We are planning for kitchen space heating MAU to have electric heat to try and maintain our electric baseline. Any prior experience in this area would be greatly appreciated.
