Building Energy Audits
Uncover hidden energy waste and prioritize cost-effective improvements with a professional energy audit. EEI delivers ASHRAE compliant assessments that identify savings opportunities and create a clear roadmap for optimizing your building’s performance.

Energy Audits
Energy represents one of the largest controllable operating expenses for commercial buildings. Yet many facilities operate far below their efficiency potential, wasting resources and budget on preventable consumption. A professional energy audit provides the data-driven foundation needed to identify where energy is being lost and which improvements deliver the best return on investment.
EEI conducts energy audits following ASHRAE standards, ensuring consistent methodology and reliable results. Our expanded project portfolio includes assessments across commercial real estate, healthcare campuses, university facilities, and industrial operations nationwide.
Understanding ASHRAE Energy Audit Levels
- Level 1 – Walk-Through Analysis: A preliminary assessment identifying low-cost and no-cost energy conservation measures. Includes utility bill review, brief site inspection, and high-level savings estimates.
- Level 2 – Energy Survey and Analysis: Comprehensive evaluation with detailed building analysis, energy use breakdown, and financial analysis of recommended improvements with payback periods.
- Level 3 – Detailed Analysis: In-depth engineering analysis of capital-intensive measures including detailed energy modeling and refined financial projections.

Our Process
- Data Collection: Gather 24-36 months of utility data, building drawings, and equipment schedules
- On-Site Assessment: Inspect building envelope, HVAC, lighting, controls, and operational practices
- Analysis: Model current performance and evaluate improvement scenarios
- Reporting: Deliver prioritized recommendations with implementation costs and projected savings


Proven Results
At Capitol Square in Madison, Wisconsin, EEI delivered comprehensive ASHRAE Level 2 audit reports for a prominent urban office tower. The analysis identified prioritized energy efficiency measures with detailed savings projections and payback calculations, providing the ownership group with a clear implementation roadmap for performance improvement.
For GS-Urbane Alewife in Cambridge, Massachusetts, EEI’s Level 2 energy audit produced a tabulated set of low-cost and no-cost energy efficiency measures, including envelope weatherstripping, domestic hot water piping insulation, and occupancy-based setback optimization alongside identification of operational issues requiring correction.
