Testing: to determine qualitative performance of equipment.
Adjusting: to regulate the specified fluid flow rate and air patterns at the terminal equipment.
Balancing: to proportion flows within the distribution system according to the specified design quantities.
Testing, adjusting and balancing, all HVAC systems in a new building is needed to complete the installation and to make the system perform as the designer intended.
Assuming that the system design and installation meets the comfort needs of the building occupants, good testing, adjusting, and balancing of the HVAC system provides occupant comfort with minimal energy input. This is extremely important in the era of rising energy costs.
The testing adjusting and balancing or TAB phase of any building construction or renovation is intended to verify that all HVAC water and air flows and pressures meet the design intent and equipment manufacturers operating requirements. It is rare to find an HVAC system of any size that will perform completely satisfactorily without the benefit of TAB.
ICB/TABB report ensures that HVAC systems operate at the highest standards of energy efficiency and ventilation effectiveness. ICB/TABB-Certified Professionals are recognized as the most competent, reliable and qualified in the HVAC industry.
Indoor air quality (IAQ) describes the condition of air inside a building. The condition of air is a combination of chemical, biological, and particulate matter, as well as temperature and humidity. IAQ is important because it affects people’s comfort, health and productivity. Certified technicians and supervisors play a vital role in IAQ.
Ideally, HVAC systems should run smoothly and with minimal noise. However, some “kick in” with vibrations and loud rolling clatter. The sound and vibration professional is vital in creating a solution using techniques of measurement and analysis. Certification in the HVAC Sound and Vibration Program is a statement that the supervisor or contractor has met ICB/TABB’s strictest standards in this field.
Building commissioning is the process of achieving, verifying and documenting the performance of a building and its various systems to ensure it meets the specifications and needs of the owner and occupants. Certification in the Commissioning Supervisor Program proves the professional is competent and trained in the HVAC systems commissioning to be performed, which meets SMACNA standards and provides more benefits to consumers.
Laboratory fume hoods play critical role in a variety of applications. They are used extensively in research laboratories where scientists and technicians work with potentially harmful substances. Academic institutions rely on laboratory fume hoods to protect students and teachers. This type of device serves to exhaust toxic, flammable, noxious, or hazardous fumes and vapors. This is achieved by confining the fumes and papers within an enclosed space and then venting them safely away from the enclosure. Fume hoods can also provide physical protection against fire, spills, and explosion.
Given the critical role laboratory fume hood plays in assuring a safe working environment, it is essential that periodic test be conducted to determine if the hood is meeting certain performance requirements. Several organizations, including both government agencies and industry associations, have developed suggested guidelines for how these tests should be conducted (such as ANSI/ASHRAE 110-1995). There is not however, a universally accepted standard of what constitutes appropriate test procedures nor fume hood performance results.
Energy use has become a major concern – for individuals, businesses, and governments. Much of the waste and inefficiency associated with energy use is directly linked to the building’s HVAC system. HVAC energy audits help facility owners determine where their systems are wasting energy. An HVAC Energy Audit Technicians recommendations play an important role in helping commercial enterprises conserve energy, improve performance and reduce costs. And that’s a win for everyone.
The management of fire and smoke has served as the underpinning of building codes in the U.S. for more than 100 years. Nearly all buildings intended for human occupancy are required by today’s codes to be designed with an assurance that, over the life of the building, occupants will be reasonably safe from fire and smoke. Building codes require the design of an integrated system of features such as walls, floors, ceiling, and structural members, as well as specific fire and smoke protection components, products, devices and systems that reinforce and cover for one another in case of the failure of any one in the event of a fire. The overall intended building performance and the depth of the designed redundancy is based on the objectives of the building owner and the occupants.
Certification in the HVAC Life Safety Level One Program provides a much-needed service to building owners and occupants. This program meets the recommendation of codes and standards by training technicians, supervisors and contractors to inspect, test and maintain fire and smoke dampers. The successful operations of these dampers may mean the difference between a nuisance fire and an uncontrollable catastrophe. Their extensive training in the HVAC industry prepares SMWIA workers and SMACNA contractors to perform these inspections efficiently and have the experience to safely make needed corrections and repairs
