Monitoring-Based Commissioning consistently delivers measurable energy and cost savings that exceed program costs, with savings varying by building type, baseline conditions, and operational practices.
Typical energy savings can range from 10-25% of baseline HVAC energy consumption, translating to 5-15% of total building energy use. These savings result from identifying and correcting operational problems, optimizing control sequences, eliminating waste, and preventing performance degradation.
Commercial office buildings can typically achieve 10-20% HVAC energy savings. A 100,000 square foot office building consuming $150,000 annually in energy might save $15,000-25,000 annually from MBCx while paying $10,000-15,000 for the service, net savings of $5,000-10,000 annually with payback under 2 years.
Healthcare and other mission critical facilities can achieve higher savings (15-25%) due to 24/7 operation, complex systems, and stringent environmental requirements, creating more optimization opportunities. A 200,000 square foot hospital might save $60,000-100,000 annually on a $400,000+ energy budget.
Educational facilities commonly save 12-20% through schedule optimization aligning HVAC operation with actual occupancy, which often differs significantly from designed schedules.
Retail and hospitality buildings achieve 10-18% savings through zone-level optimization, plug load management, and demand-based ventilation in variable-occupancy spaces.
Savings sources include (these are estimates and others may have different experiences that are larger or smaller):
Correcting simultaneous heating and cooling (~2-5% savings)
Optimizing supply air temperature reset (~3-7% savings)
Adjusting static pressure setpoints (~2-4% savings)
Eliminating unnecessary equipment operation (~5-10% savings)
Repairing failed economizers (~5-15% savings in suitable climates)
Calibrating sensors and actuators (~2-5% savings)
Implementing demand-based ventilation (~5-15% savings)
Non-energy benefits add value beyond energy savings: improved comfort reduces complaints, extended equipment life defers capital replacement, maintained warranty compliance protects investments, and reduced maintenance costs from proper operation.
Persistence of savings: MBCx’s greatest value is maintaining savings over time. Without ongoing monitoring, 50-80% of initial commissioning savings typically disappear within 3-5 years as systems degrade. MBCx prevents this loss, compounding value year after year.
Actual savings depend on baseline conditions; poorly operating buildings offer more improvement potential while well-maintained buildings yield smaller but still valuable savings.
