Frequently Asked Questions
What does TAB mean in HVAC?
+
TAB stands for Testing, Adjusting and Balancing, a critical process that ensures air and water systems in HVAC installations perform exactly to design intent. At Stonehaven, we conduct NEBB-standard TAB across AHUs, FCUs, and chillers, validating every flow rate and system parameter to guarantee consistent comfort and energy efficiency across your building.
What is Pre-TAB in HVAC?
+
Pre-TAB is the preparation stage that verifies all mechanical systems are ready for formal testing. Stonehaven’s engineers complete duct leakage inspections, valve settings, and control checks before final balancing. This early verification helps eliminate rework, shorten commissioning time, and ensure smooth consultant approval at handover.
Is TAB the same as commissioning?
+
Not exactly. Commissioning covers the full verification of all MEP systems, while TAB focuses solely on fine-tuning HVAC airflow and water flow performance. Stonehaven integrates both processes, combining commissioning management and air & water balancing to ensure your mechanical systems are compliant, efficient, and ready for occupancy.
What does a TAB report include?
+
A TAB report records all system readings from airflow and pressure differentials to pump head losses and balancing valve positions. Stonehaven’s digital TAB reports include consultant approved documentation, traceable readings, and linked dashboards, giving project teams transparent insight into system performance and compliance.
Why is HVAC TAB essential for sustainable construction?
+
Balanced HVAC systems consume less energy and deliver better indoor air quality. Stonehaven’s TAB and IAQ validation services align with LEED, Estidama, and BREEAM frameworks, ensuring every building meets its sustainability goals through optimised air distribution and efficient thermal control.
