Energy Audit

Our energy efficiency solutions always start with an ASHRAE-level energy audit. It is a comprehensive evaluation of a building’s energy performance and involves a detailed analysis of the building’s energy use, HVAC systems, lighting, and other energy-consuming equipment to identify areas where energy efficiency improvements can be made.

Energy Audit Process

The energy audit provides you with a roadmap for optimizing your facility’s energy use and reducing energy costs while ensuring that the indoor environment is comfortable, healthy, and safe.

Our energy management team will guide you throughout the process and meet with you before conducting the audit. Some of the information our certified energy auditors will collect and the systems we look at during an audit include:

  • Current HVAC configuration
  • All lighting and plug loads on site
  • Hours of operation for all energy-consuming equipment
  • Power consumption per equipment type
  • Specialty loads
  • Building envelope

Once complete, we will provide you with a detailed report outlining our findings and recommendations. Our turnkey solution is customizable, integrating the future seamlessly with your existing systems.

Level 1:


An ASHRAE Level 1 audit helps businesses get started with making energy improvements. It consists of a Preliminary Energy Use Analysis (PEA), a complete  walkthrough survey, and benchmarking of your facility. Based on what we find, we will identify low-cost and no-cost energy efficiency recommendations.

Level 2:

ENERGY Survey & Analysis

The Level 2 audit follows and considers the findings of a Level 1 audit. However, the it involves an end-use breakdown for space heating and cooling, air distribution, lighting, water distribution, and more. Our detailed analysis will determine key operating parameters, or equipment that makes up greater than 80% of the energy use of the building. We also ​​review current O&M procedures to identify areas where you can improve efficiency, reduce costs, and enhance safety.

Level 3:


A Level 3 audit takes it a step further. It includes a more in-depth analysis of usage and potential changes to a building’s energy consumption. Along with analysis and refined measurements, it also includes hourly simulations.
