Energy Calculators

Motor Load Calculator

What does it cost each year to operate an electric motor? With the motor load calculator you can quickly estimate annual energy use and cost for any electric motor. The calculator is a versatile energy management tool which accepts measured current, full load amps or rated horsepower inputs.

Ventilation Cost Calculator

A small exhaust fan left running at night can be easily overlooked, but you may be surprised by the energy cost of leaving it on. Use the ventilation calculator to determine the annual energy consumption and cost for heating ventilation air to space temperature.

Natural Gas Electricity

Water Savings Calculator

Estimate potential water and cost savings from installing different water efficiency toilet and urinal options.

Toilet Replacement

Urinal Replacement

Constant Volume Air Handler Calculator

Estimate the amount of heating or mechanical cooling that is required to supply conditioned air to a space in a constant volume system. You can also see the impact on outside air usage in a system with an airside economizer.

Inlet Guide Vane to VFD Retrofit Calculator

Assess the operating cost of a fan system using variable inlet vanes vs. variable frequency drive to achieve capacity control. Input your motor characteristics, load profile, and cost of energy to evaluate the energy consumptions and energy costs of each system.
