A commercial energy audit is the study of a building’s utilities consumption (electricity, gas, water) with an on-site inspection that evaluates all aspects of the facility including: lighting, air conditioning, heating and ventilation equipment, HVAC controls, and all other energy equipment.

After the on-site assessment is performed, a detailed report is generated that prioritizes energy conservation measures (ECMs) with quantifiable cost savings analysis and return on investment for each recommendation.



An energy audit will provide a strategic roadmap to minimize operating expenses and reduce a building’s energy costs by 10-40 percent.

IMPACTenergy’s energy audits and proven optimization methods deliver a reduced carbon footprint resulting in direct financial savings. While the energy savings potential vary, our process can:

  • Improve financial performance by reducing operating expenses
  • Increase property value and extend the life of a facility
  • Increase building efficiency through system optimization
  • Gain marketplace competitive advantage through recognition programs
  • Improve your company’s image by “greening up”
  • Reduce your company’s environmental impact


The energy audit process is customized for each property. IMPACTenergy provides a tailored program based on goals you have set for your facility and its operation. We base our Energy Audit program on The American Society of Heating, Refrigerating and Air Conditioning Engineers’ (ASHRAE) Procedures for Commercial Building Energy Audits. ASHRAE’s standards are considered the benchmark for building energy codes.

Levels of Commercial Energy Audits

Various degrees of energy analysis can be performed on any given building. Determining major energy-savings improvements require deeper analysis than simply comparing the level of efficiency of a building relative to others. As a result, ASHRAE organized levels of analyses into the categories below.


The preliminary energy audit calculates the building energy utilization index based on a building’s gross square footage, 1-3 years of energy usage, and the building’s characterization use. This preliminary information allows us to compare energy consumption for similar buildings. This analysis is similar to comparing the “miles-per-gallon” rating for automobiles.

Level 1

The ASHRAE Level 1 Audit focuses on low-cost/no-cost energy conservation measures, and provides a list of higher cost energy saving suggestions. In addition to tasks performed in the Overview Audit, the ASHRAE Level 1 audit report describes how much energy and financial savings can be achieved by implementing each energy conservation opportunity. If the building has energy improvement potential, options may include performing a Level 2 Energy Audit; a Level 2 audit may be coupled with LEED-EBOM or ENERGY STAR services.

Level 2

ASHRAE Level 2 audits both identify all appropriate energy conservation measures for a facility, and provide financial analysis based on implementation costs, operating costs, and attainable savings. A report will outline each energy conservation measure and detail its savings, cost, and time for return on investment. In addition, ASHRAE Level 2 audits will specify any changes to operations and maintenance procedures.



There are many program opportunities for your business or company through state, federal, local, and utility incentives and policies that support renewable energy and energy efficiency for commercial buildings.
