Net Present Value
NPV = discounted cumulative savings minus incremental cost. Positive = net financial benefit over the equipment lifecycle.
Carbon Impact
Steady-state conduction model per SAE J1503 (cab air conditioning performance). Effective ΔT is weighted by heating/cooling fraction for the selected climate. Diesel fuel savings converted from HVAC kWh at engine-driven compressor efficiency (32%). Covers conduction only — actual savings may be higher due to reduced solar gain and improved operator comfort.
