Energy Audits and Assessments

   What is an Energy Audit?

     A home energy audit evaluates an existing home to determine where and how energy is being lost, what systems are operating inefficiently and what cost-effective improvements can be implemented to enhance occupant comfort, make the home more durable and lower utility costs. The visual inspection may include limited use of diagnostic testing equipment. Its purpose is to assess the general energy performance of an existing home including:

  • Building envelope features (windows, doors, insulation, ducts) and functionality
  • Heating, cooling and ventilation equipment types, characteristics and functionality
  • Appliance and lighting characteristics
  • Comfort complaints
  • Visible moisture issues
  • Visible health and safety issues

  Where can I get an audit?

   Most homeowners in the Twin Cities metro area have access to low cost energy audits through their gas utility company. While we would be glad to provide you with a full assessment, it will be less expensive through your utility company.

What is the difference between an energy audit and a home performance assessment?

Energy audits, while looking at all the systems of a house, do not necessarily connect the dots and view the house as an integrated system.   A home performance assessment looks at all the components of a house and how they influence one another. Home energy efficiency depends on a balance between air sealing, insulation, ventilation and moisture control. Let us help you create a balanced home ecology.


Home Performance Assessments

A Home Performance Assessment includes all of the inspections provided in the energy audit and also includes diagnostic testing using specialized equipment such as a blower door, duct leakage tester, combustion analyzer and infrared camera to determine: 

  • The amount and location of air leaks in the building envelope
  • The amount of leakage from HVAC distribution ducts
  • The effectiveness of insulation inside walls and ceilings
  • Any existing or potential combustion safety issues
