Energy Audits

The objectives of an energy audit are to identify and develop modifications that will reduce the energy use and/or cost of operating a building. Greenwise Strategies conducts comprehensive building audits based on American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) procedures for Commercial Building Energy Audits (RP-669 and SP-56). These procedures for conducting audits are accepted as the industry gold standard and proven to be effective for any size project.

Significant utility and government incentives may be available to offset the costs of the analysis and/or implementation of the recommended conservation measures. (Dependant on your location and utility service provider)!

If you would like to schedule a complimentary walk-through of your facility (travel fees may apply) or learn more about the details and pricing for conducting an energy analysis of your facility, please submit your name, email and “energy consult” in the subject line. One of our representatives will contact you to discuss.

Preliminary Energy Use Analysis:

  • Analyze two to three years of utility data (electric, gas, water).
  • Develop the Energy Utilization Index (EUI) and compare with similar buildings to determine if further engineering study and analysis are likely to produce significant energy savings.


The audits can be performed in three levels of complexity and detail:

ASHRAE Level I: Conduct a brief on-site survey of the building to identify and provide a savings and cost analysis of low-cost/no-cost measures. Also, provide a listing of potential capital improvement that merit further consideration based on costs and potential savings.

ASHRAE Level II-Energy Survey and Engineering Analysis: Energy Survey and Engineering Analysis: This includes a more detailed building surveyand whole building utility consumption analysis. The study will analyze building usage, occupancy and energy-using systems such as lighting, hot water systems, Heating Ventilation & Air Conditioning (HVAC), MEP design, plug loads, motors, building envelope and any other elements that may impact energy consumption.

  • This Evaluation Results in:
  • Summary of current energy use and costs associated with each end-use
  • A list of Energy Conservation Measure (ECM) recommendations
  • Estimated implementation costs & anticipated savings for all practical measures
  • Financial & Economic Evaluation including payback, Internal Rate of Return (IRR), and Return on Investment (ROI) for the proposed ECM’s
  • Discussion of feasible capital-intensive measures that may require a Level III analysis
  • Identification of Government and Utility Incentives

ASHRAE Level III – Detailed Analysis of Capital-Intensive Modifications: Detailed Analysis of Capital-Intensive Modifications: This level of engineering analysis focuses on potential capital-intensive projects identified during the Level II analysis and involves more detailed field data gathering as well as a more rigorous engineering analysis. It provides detailed project cost and savings calculations with a high level of confidence sufficient for major capital investment decisions.

* Optional: Greenwise Strategies will analyze utility bills to establish an energy usage baseline by benchmarking the facility using the ENERGY STAR Portfolio Manager. Click here for more information on ENERGY STAR® Benchmarking.
