Whole building commissioning typically encompasses all energy-using systems and equipment that impact occupant comfort, building performance, and operational efficiency.
HVAC systems receive primary focus: chillers, boilers, cooling towers, air handling units, variable air volume boxes, cooling distribution units, exhaust fans, heat pumps, and associated pumps and controls. Building automation systems (BAS) are thoroughly tested to verify proper operation, sequences, setpoints, alarms, and integration with mechanical equipment.
Lighting and daylighting controls, including occupancy sensors, photocells, and dimming systems, are verified for proper operation and energy code compliance. Domestic hot water systems, heat recovery equipment, and renewable energy systems (solar thermal, photovoltaic, geothermal) are commissioned to ensure optimal performance.
Building envelope components include air barriers, insulation continuity, fenestration, and moisture management systems. Life safety systems coordination, including smoke control and fire alarm integration with HVAC, is verified during commissioning.
The specific scope depends on project type, goals, budget, schedule, potential incentives, and applicable codes. Energy-intensive facilities may include process equipment, commercial kitchens, data centers, or laboratory systems. The commissioning plan documents which systems will be included and the level of testing for each.
