We have a new build out of a small office in an existing industrial building. We will be adding new package roof top units with DX cooling and gas heat to condition the office space. We are pursing the equipment efficiency portion of Option 1. Section 2.9 of the Core Performance Guides lists package units but the efficiency requirements are for cooling only. Gas furnaces are mentioned under a separate bullet with gas unit heaters. Do we just need to meet the efficiency requirements of the package unit bullet or do we also need to meet the gas furnace requirement?
