How do I conduct a comprehensive building energy audit?

Conduct energy audits through systematic data collection, building inspection, equipment analysis, and energy modeling to identify efficiency opportunities.

A comprehensive building energy audit systematically evaluates energy consumption patterns and identifies efficiency improvement opportunities through structured analysis and testing procedures.

Phase 1: Data Collection Gather 12-24 months of utility bills, building drawings, equipment specifications, and operational schedules. Analyze energy use intensity (EUI) and benchmark against similar buildings using tools like ENERGY STAR Portfolio Manager.

Phase 2: Building Walkthrough Inspect building envelope for air leaks, insulation gaps, and thermal bridging. Document HVAC systems, lighting, controls, and major energy-consuming equipment. Use thermal imaging cameras to identify heat loss areas.

Phase 3: Detailed Assessment Measure air leakage using blower door tests. Analyze HVAC performance through temperature, humidity, and airflow measurements. Evaluate lighting levels and power density. Test building automation and control systems.

Phase 4: Energy Modeling Develop computer models using software like EnergyPlus or eQUEST to simulate current performance and predict improvement scenarios. Calibrate models against actual consumption data.

Phase 5: Opportunity Analysis Identify energy conservation measures (ECMs) with cost-benefit analysis. Prioritize improvements based on payback periods, energy savings potential, and implementation complexity.

Reporting and Recommendations Document findings with energy savings projections, implementation costs, and recommended action plans. Include utility rebate and incentive opportunities.
