19-1 Logic Appears to Add Interpretation

[JacksonJ-KC]

System coil capacities for the baseline building design shall be based on sizing runs for each orientation in accordance with Table G3.1, No. 5[a] and Section G3.1.2.2.1, and shall be oversized by 15% for cooling and 25% for heating.

The logic has added interpretation around which systems the rule is intended for. The logic is only applied to heatpump heating, furnace heating, and DX cooling coils, when 90.1 refers broadly to "System coil capacities".

Calculated Values also incorrectly display the oversizing factors as 0.0 when the coils are HW/CHW.
