Savings Calculators
The Wisconsin Public Service Savings Calculators will help you pick out energy efficient appliances and calculate your estimated savings.
- Thermostat Setback Calculator
We can help you estimate how much you can save by setting back your thermostat! - Aerosol Duct Sealing Calculator Screening Tool
Estimates the cooling, heating, and combined annual dollar savings that can be achieved by sealing leaks in HVAC ductwork. - Gas Cooling Screening Analysis Tool
Provides a rough estimate of the annual cost savings and payback period for a gas-fired chiller relative to a conventional electric compressor-based chiller, based on your cooling load and the electric and gas prices you enter. - Packaged RTU (roof-top unit) Efficiency Screening Tool
Estimates energy and peak demand savings as well as payback period for high-efficiency packaged roof-top air conditioning units. - Screening Tool For Indirect Lighting
Compares the total installed costs, annual operating and maintenance costs, and cooling costs of up to three direct and indirect lighting strategies. It also estimates a simple payback period for the indirect lighting alternatives. - HID (high-intensity discharge) Track Lighting Savings Calculator
Estimates the annual energy cost savings and payback periods for metal halide and high pressure sodium track lights compared to halogen track lights. It also estimates total costs of ownership for each lighting technology over a 10-year period. - Fluorescent High-Bay Lighting Savings Calculator
Estimates the annual energy savings and simple payback period achievable by replacing existing metal halide lamps with fluorescent lamps in high-bay applications. - Personal Dimming Cost-Effectiveness Calculator
Estimates the bill savings and payback period for a lighting system that permits individuals to adjust fluorescent lighting to their personal preference in an office setting. - Harmonic Mitigating Transformer Cost-Effectiveness Evaluation Tool
Estimates the annual energy savings and simple payback period for installing a harmonic mitigating transformer versus a conventional distribution transformer. - Evaporator Fan Controller Cost-Effectiveness Estimator
Estimates the electricity and dollar savings potential and payback period for evaporator fan controllers on walk-in refrigerators and freezers, based on fan power, duty cycle, electric rate, and installed cost information that you provide. - Gas-Fired Water Heater Screening Tool
Determines the energy consumption and payback periods for standard commercial and ultra-efficient commercial water heaters and compares them with consumption and payback for residential models. By necessity, this screening model makes simplifying assumptions, so use it for initial screening only.
