(TAB) Testing and Air Balancing
A successfully completed building is the goal of every new project. But what happens if a project is complete, and critical areas of design intent have failed? Even with the most talented construction and design teams, post construction failures occur, and mechanical systems are no exception. Today’s complex mechanical systems add tremendous value to the overall function of a building. But many require testing and balancing to perform at optimum level and fulfill the original vision of design intent. It is a final step in the construction process that saves time, money and frustration down the road. Owners and engineers understand the importance of testing and balancing and are demanding professional independent test and balance services at the completion of every new project.
New System Commissioning
Every building has a complex system of air flow. So every building needs qualified individuals to make sure the flow is always on the go. These are specialized workers in the field of testing, adjusting and balancing, or tab. Ensuring that air moves safely and efficiently throughout a building or a series of buildings is the duty of certified TAB technicians. Our knowledge and ability to troubleshoot problems are vital to a building operating at its fullest capacity. TAB engineer’s knowledge spans from comprehending all the components of HVAC systems, conducting proper testing and measurements to making adjustments and correcting problems as they arise. Maintaining energy efficient systems or what others may call green building has always been a fundamental duty for our tab technicians. We incorporate math and strong problem solving skills while working on complex air delivery systems. Building operators, facilities managers and business owners rely on our tab workers to maintain a safe and healthy environment. Our TAB Technician, TAB Supervisor and TAB Certified Contractor to oversee large and small scale projects.
Rebalancing Existing Systems
The objective of an air balance study is to restore a system to near its design conditions. All measured air flows should fall within 10% of design. This means that prior to starting an air balance, the design condition should be known. The best source for these numbers is from the as-built HVAC drawings. Additionally, for optimal operation, there should be at least one path with fully open dampers between the supply fan and an air outlet. The purpose of a balancing damper is to meter the volume of air to a specific diffuser. Airflow adjustments are accomplished by changing the position of balanced dampers within the ducts. Some systems have a damper at each outlet. Some have a single damper at a VAV (variable air volume) box that feeds multiple outlets. No matter the job scope our experienced TAB Technicians will get your system operating at design conditions.
