Cruise Ship HVAC Energy & Fuel Savings Calculator

Estimate cruise ship HVAC electricity savings, auxiliary-generator fuel avoided, shore-power savings, CO2 reduction, annual operating benefit, payback, NPV and IRR. Advanced mode separates chillers, ventilation fans, pumps and terminal loads while modeling retrofit performance, onboard generation, shore power and full project CAPEX.

HVAC Energy
Convert average cruise HVAC load and retrofit performance into annual MWh saved
Fuel + Shore Power
Value savings differently when HVAC electricity comes from onboard generators or shore power
Retrofit ROI
Calculate fuel savings, annual cash benefit, payback, NPV, IRR and break-even performance

Cruise HVAC Energy & Fuel Savings Results

Simple HVAC efficiency investment screen

Enter HVAC data
Enter cruise ship HVAC load, operating time, expected energy reduction, generator assumptions and project cost to calculate energy savings and ROI.
Planning estimate only. Actual cruise ship HVAC performance depends on ambient temperature and humidity, passenger occupancy, fresh-air requirements, cabin and public-space setpoints, chiller loading, chilled-water and seawater temperatures, fan and pump curves, heat-recovery systems, galley and hotel loads, control logic, equipment condition, itinerary, shore-power use and generator dispatch. Use vessel trend data, OEM performance curves, engineering studies and shipyard quotations for investment decisions.
