Institutional central plant electrification and simultaneous hydronic heat recovery engineering model. Sizes 4-pipe simultaneous heating and cooling chiller-heaters (Multistack, Carrier AquaForce, Trane Sintesis), models 44°F chilled water & 120°F–140°F hot water loops, computes simultaneous heat-of-recovery COP (6.5 to 8.8), evaluates boiler natural gas displacement, cooling tower water evaporation savings, stacks utility heat pump rebates with IRA §179D tax deductions, and computes 20-year net present value (NPV).
