For HVAC system commissioning, the following should be verified and
documented:
• Manufacturer’s requirements for airflow for biological safety cabinets and
laminar flow clean benches have been met.
• Exhaust system configuration, damper locations, and performance
characteristics, including any required emission equipment, are correct.
• Control system operates as specified. Controls include fume hood alarm;
miscellaneous safety alarm systems; fume hood and other exhaust airflow
regulation; laboratory pressurization control system; laboratory temperature
control system; and main ventilation unit controls for supply, exhaust, and heat
recovery systems. Control system performance verification should include
speed of response, accuracy, repeatability, turndown, and stability.
• Desired laboratory pressurization relationships are maintained throughout the
laboratory, including entrances, adjoining areas, air locks, interior rooms, and
hallways. Balancing terminal devices within 10% of design requirements will not
provide adequate results. Additionally, internal pressure relationships can be
affected by airflow around the building itself. See Chapter 24 of the 2009
ASHRAE Handbook—Fundamentals for more information.
• Fume hood containment performance is within specification. ASHRAE Standard
110 provides criteria for this evaluation
• Dynamic response of the laboratory’s control system is satisfactory. One
method of testing the control system is to open and shut laboratory doors
during fume hood performance testing.
• System fault tree and failure modes are as specified, including life safety fan
system shutdown impact on proper provisions for egress from the building
within allowable limits of door opening force requirements.
• Standby electrical power systems function properly.
• Design noise criterion (NC) levels of occupied spaces have been met.
