Specialist TAB and HVAC Commissioning — two disciplines, one standard: performance as designed.

TAB Commissioning TAB vs Commissioning

Testing, Adjusting & Balancing

TAB is the systematic process of verifying that all mechanical systems in a building perform in accordance with the design intent. Without TAB, you may accept a building with systems that will never meet design specifications.

Standards We Follow
ASHRAE, SMACNA, and NEBB standards for all testing and balancing work. Documentation accepted by engineers, owners, and regulatory authorities.
The TAB Process
1
Pre-TAB Review
Review design documents, equipment schedules, and system schematics to establish baseline expectations.
2
System Testing
Measure actual airflow, water flow, temperatures, pressures, and equipment performance against design values.
3
Adjusting and Balancing
Adjust dampers, valves, fan speeds, and controls to bring all systems into compliance with design specifications.
4
TAB Report
Comprehensive report documenting all measurements, adjustments, and final verified performance data. Delivered within 48 hours.

HVAC Commissioning

Commissioning is a systematic quality assurance process that verifies HVAC systems are designed, installed, tested, and capable of being operated and maintained in accordance with the owner's project requirements.

Why Commissioning Matters
Studies show that commissioned buildings use 8 to 20% less energy than non-commissioned buildings. Commissioning also reduces occupant complaints, equipment failures, and warranty claims.
Commissioning Phases
1
Pre-Design Phase
Develop the Owner's Project Requirements (OPR) and Basis of Design (BOD) documents that define performance expectations.
2
Design Review
Review design documents to verify they meet the OPR. Identify design deficiencies before construction begins.
3
Construction Observation
Site visits during installation to verify equipment and systems are installed per design specifications.
4
Functional Testing
Systematic testing of all HVAC systems and controls under various operating conditions to verify performance.
5
Commissioning Report
Comprehensive documentation of all commissioning activities, test results, deficiencies, and final system performance.

Commissioned buildings use 8 to 20% less energy. Balanced systems last longer, cost less to operate, and keep occupants comfortable.

TAB vs. Commissioning

Both services verify performance. The difference is scope and timing. Many projects benefit from both.

Testing, Adjusting & Balancing

Focused on measuring and adjusting airflow, water flow, and equipment performance to match design values.

  • ✓Airflow measurement at every terminal device
  • ✓Hydronic system flow balancing
  • ✓Fan and pump performance verification
  • ✓Zone-by-zone balancing to design specs
  • ✓Deficiency identification and reporting
  • ✓Energy benchmarking baseline data
Best For
New construction handover, existing building troubleshooting, energy audits
Timing
At project completion, before handover
Report Delivery
Within 48 hours of field completion

HVAC Commissioning

A broader quality assurance process spanning the entire project lifecycle, from design review through construction and into operation.

  • ✓Owner's Project Requirements development
  • ✓Design document review and verification
  • ✓Construction phase site observations
  • ✓Equipment startup and pre-functional testing
  • ✓Functional performance testing
  • ✓Controls and BMS verification
Best For
New construction, LEED certification, complex HVAC systems, owner protection
Timing
From pre-design through seasonal operation
Energy Savings
8–20% less energy vs non-commissioned buildings
