Energy Auditing

GreenPath will help building owners optimize energy performance by conducting an energy analysis or audit to identify and develop modifications that will reduce the energy use and/or cost of operating a building.

How does a building owner or manager begin to get a handle on energy use and cost saving opportunities?
Two key tools are benchmarking energy performance and energy audits. Benchmarking performance gives a picture of how any given building performs relative to peer building with similar operating characteristics and is the first step to understanding and reducing energy consumption. The next step, an energy audit, digs more deeply into a building’s energy use and systems to systematically identify and analyze opportunities for savings. An audit can identify facility-specific energy conservation measures (ECMs) that can reduce your electricity, natural gas and water consumption, saving your organization ongoing operational costs.

GreenPath will audit a facility and create an energy savings plan. We follow ASHRAE guidelines for performing audits (levels I, II and III) and can provide the appropriate audit of your facility based on your project’s requirements and objectives. We offer the following levels of Commercial Energy Auditing depending on the physical characteristics of a building and the needs of the owner:


  • Preliminary Energy Use Analysis – Analyze building EUI to similar historical utility use and cost. Develop the Energy Utilization Index (EUI) of the building. Compare the building (EUI) to similar buildings to determine if further engineering study analysis is likely to produce significant energy saving.
  • Level I – Web-based virtual analysis. Assess a building’s energy cost and efficiency by analyzing energy bills and conducting a brief on-site survey of the building. A Level I energy analysis will identify and provide a saving and cost analysis of low-cost/no-cost measures. It will also provide a listing of potential capital improvements that merit further consideration and include a sustainability analysis to help a company become more environmentally friendly.
  • Level II – On-site Energy Survey and Analysis. This includes a more detailed building survey and energy analysis. A Level II energy analysis will identify and provide the savings and cost analysis of all practical measure, along with a discussion of any changes to operation and maintenance procedures.
  • Level III – 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 saving calculations with the high level of confidence sufficient for major capital investment decisions.

These levels of Energy Auditing will help our clients reach their energy target and follow the ASHRAE Guidelines for Commercial Building Energy Audits and comply with LEED standards for attaining EBOM and EA credits.
