What is a Home Energy Assessment?

If your home qualifies, we will send a certified energy expert to take a close look at your home. The assessor will identify ways for you to reduce your energy usage, give you estimates on how much the upgrades will cost, and tell you how much you can expect to save. The assessor will also conduct a combustion safety check and a carbon monoxide test. The assessor may even install some energy-saving measures on the spot at no cost.

What will the assessor look at in my home?

The energy expert will analyze many features of your home, including:

  • Building construction and tightness
  • Heating and cooling systems (if applicable, the energy expert will install a clock-programmable thermostat at no cost)
  • Kitchen and laundry appliances
  • Lighting (if applicable, the energy expert will install ENERGY STAR® rated compact fluorescent light bulbs)
  • Water heating equipment (if applicable, the energy expert will install up to two faucet aerators, a low-flow showerhead, pipe insulation and water heater insulation wrap)
  • Windows, doors and insulation levels
  • Plug load review (if applicable, the energy expert will provide you with a smart strip)

How do I qualify for a Home Energy Assessment?

Alliant Energy must supply your home's primary heating energy or electric cooling energy (if you don't heat with natural gas). The primary heating source is the heating equipment permanently installed in your home (furnace, boiler, etc.). All other heating sources (space heater, corn stoves, etc.) are considered supplemental.

  • Your home must have been built before January 1, 2006.
  • If you are a renter, you must have the property owner’s approval. Alliant Energy would be happy to contact the property owner for approval.
  • Eligible customers may receive an assessment once every five years.

What are the different options for a Home Energy Assessment?

Eligible customers may select either a basic or comprehensive energy assessment. The basic option is free, while the comprehensive option requires a $100 customer co-pay.

Are there any alternatives to an in-person Home Energy Assessment?

We understand you are busy and scheduling a Home Energy Assessment can be difficult. You can get a free real-time, virtual home energy assessment online through the Department of Energy’s Home Energy Saver (HES) tool. The tool recommends energy-saving upgrades that are appropriate to your home, the climate and local energy prices. Be sure to check for rebates before making energy-efficient updates.
