Energy benchmarking is the process of measuring a building’s energy consumption and comparing it against similar properties or industry standards using metrics like EUI (Energy Use Intensity). EUI measures annual energy consumption in BTU per square foot, enabling fair comparison between different building sizes and types. Most commercial buildings range from 15-25 EUI for efficient facilities to 30-50 EUI for average performers.
Assessment Methodology
Benchmarking requires 12 months of utility data and building characteristics including square footage, occupancy type, operating hours, and climate zone. Software platforms like ENERGY STAR Portfolio Manager track consumption trends and identify underperforming HVAC systems. Benchmarking typically costs $500-$2,000 per building and reveals optimization opportunities worth 10-30% energy savings.
Operational Advantages
Regular benchmarking drives continuous improvement by establishing baseline metrics and tracking progress toward energy reduction targets. Identifying high-consumption periods allows HVAC technicians to diagnose equipment failures, control malfunctions, or operational inefficiencies. Many jurisdictions now mandate annual benchmarking for commercial buildings exceeding 25,000 square feet.
