HVAC Energy Savings Calculator

This HVAC Energy Savings calculator allows you to estimate potential energy and cost savings by upgrading to more energy-efficient HVAC systems.

What is an HVAC cooling energy savings calculator?

An HVAC cooling energy savings calculator is a tool used to estimate potential energy and cost savings by upgrading to a more energy-efficient HVAC system. The calculator looks at factors like the current HVAC system’s efficiency, the efficiency of the new system being considered, the size of the HVAC unit, the climate zone, and the energy costs in the local area.

Who uses an HVAC cooling energy savings calculator?

HVAC cooling energy savings calculators can be used by anyone—HVAC organizations, technicians, and property owners. The calculator helps estimate savings from reduced energy consumption and associated costs. These details help technicians and property owners to make informed decisions based on the results.

How accurate are the results?

Whether or not the results are accurate depends on input details and the assumptions made by the calculator. But other factors can affect the recommendations too. In order to get the best results, you should consult with a licensed engineer.

How do you calculate HVAC cooling energy savings?

To calculate HVAC cooling energy savings, add the details about the HVAC usage for cooling, including current and new SEER ratings.

You’ll have to include:
– Avg. Usage per Day
– Location
– AC capacity (in BTU)
– Current SEER
– New SEER

Once the information is entered into the calculator, you’ll get an estimate of the potential HVAC cooling energy savings.

What is the HVAC cooling energy savings calculation formula?

The formula used to estimate base HVAC cooling energy savings is:

Usage per Month (in hours) = Avg. Usage per Day (in hours) * 30

Current:

Current Energy Consumption per Day (in watts) = AC Capacity (in BTU)/Current SEER Rating

Consumption per Month (in kilowatts) = (Energy Consumption per Day (in watts) * Usage per Month)/1000

Current Cooling Cost per Month = (Consumption per Month * Average Cost of Electricity (per Kwh))

New:

New Energy Consumption per Day (in watts) = AC Capacity/New SEER Rating

Consumption/Month (in kilowatts) = (Energy Consumption per Day (in watts) * Usage per Month)/1000

New Cooling Cost per Month = Consumption per Month * Average Cost of Electricity (per Kwh)

Savings:

Savings per Month = Current Cooling Cost per Month – New Cooling Cost per Month

Savings per Year = (Savings per Month  * 12)

Savings % = (Savings per Month/Current Cooling Cost per Month) * 100
