90.1 App G baseline HVAC

Hello all,

Table 3.1.1B states that the Heating Type for System #5 (Packaged VAV with Reheat) is "hot-water fossil fuel boiler." Does this pertain to the primary heating in the RTU, or reheating at the zone level, or both? I am looking to determine what the baseline system type would be for an Appendix G model. Originally I thought a gas-furnace with electric reheat, but that doesn't appear to be correct.

Hi Will,

The Baseline for system 5 would be hot water from a fossil fuel boiler for
both the primary and zone level HVAC equipment.
