The process incorporates a holistic approach to a project and the building systems encompassing both design, construction and operation. It is a highly effective way to ensure that the built environment is operated in accordance with ownerâs program goals and construction documents. The key is that the entire team, including the CxA, participates in the process. The process begins in the design phase with CxA review of the OPR and BOD developed by the design team.
During design, the CxA reviews the design to make sure that the design team is
following
the OPR, that interdisciplinary coordination is occurring and that maintainability is being designed into the system. The CxA also works with the design team to develop commissioning specifications that will inform contractors during construction what they need to do to complete their scope of work in order to achieve commissioning. The CxA will provide continuity as the ownerâs expert during construction, working with all subcontractors to verify that they are installing equipment and performing tests in a way that will lead to a functionally complete building being returned to the owner.
One of the most common misconceptions of CxAs is that they are a guarantor of the performance of a buildingâs systems. This is usually due to a misunderstanding of the role of the CxA and how they are hired and contracted.CxAs must be able to communicate with a variety of trades, including general and specialty contractors, to ensure that their work is being hvac test and balance performed correctly. This is particularly important during construction because it is the constructors who will be installing the commissioned systems.
CxAs should have clear lines of communication with all parties to the project and their authority should be specified in the contract.In addition, CxAs must be able to work within the context of the projectâs United States of America schedule and understand how their work affects 75081 the overall project. This is especially important during construction since the CxA needs to be able to work around critical path items and still be able to perform testing and installation verification well before occupancy.
Air Balance Basics
One common reason for a building to have an unbalanced HVAC system is because the ventilation is not taking in enough air. This can be caused by a variety of things, including a closed vent, a fan that is running continuously and even a clogged filter. A great way to test the amount of airflow coming out of a vent is to place a piece of paper over it and observe how far the bottom of the paper blows away from the wall. A good paper should float and the system is out of balance if it blows hard against the wall.
Often, this is the easiest 1651 N Glenville Dr. Ste 201 problem to diagnose and the cheapest.A few minutes of airflow testing will show if Texas there is an issue with a room or the entire system. Once the airflow is sorted out, itâs just a matter of opening dampers or louvers in rooms that are having issues and adjusting them accordingly
