Cx begins with defining the Ownerâs Project Requirements which becomes the basis of decisions related to design, construction and operation. The next step is developing the commissioning scope and plan.
Air Balance
The most important part of a buildingâs air conditioning and ventilation systems is air balancing. This process ensures that the mechanical air-moving devices are performing within their engineered specifications and correctly installed.It also ensures that the conditioned air is reaching the occupants of building commissioning services the commercial building properly.
Air balancing is the only way to verify that your HVAC system is bringing in and exhausting enough outdoor air to keep your building comfortable. If a building brings in more outside air than it exhausts, it will require excessive energy to maintain comfort. This can cause your facility to waste a large percentage of its total electrical usage.
Additionally, uneven airflow can lead to cold drafts in some rooms and stuffy United States of America or humid conditions in other rooms. This can result in discomfort for your occupants, lower productivity, higher utility bills, and costly repairs. The good news is that a simple investment in air balancing can resolve these issues.
Air Distribution
The air system commissioning process checks that the air distribution systems are operating as designed to deliver clean, healthy air to occupants. The process also checks that ductwork is properly routed and that fans are operating the way they should.
Itâs a 1651 N Glenville Dr. Ste 201 good idea to start the commissioning process as early as possible, ideally right from the conceptual phase. This allows a comprehensive review of the design and construction documents, and identifies issues to address during construction.
Commissioning is known to yield high returns through energy cost reduction, sustainability, reduced O&M costs, improved building efficiency and occupant comfort. It also enables a facility to meet goals set in energy and sustainability rating systems, which require rigorous verification and documentation. The commissioning process is led by a qualified individual or firm (AKA the commissioning provider, or CxP) who must be independent of the project team to ensure unbiased performance. The industry standard most recognized arrangement is for the CxP to be contracted directly by the owner to ensure this.
Heating
The heating, ventilation, and air conditioning systems in most buildings are critical for maintaining occupant comfort. Commissioning can help ensure these systems are properly installed and functioning.
ASHRAE has a number of resources available to guide new construction projects through the commissioning process. These include a manual for project teams and a set of customizable commissioning checklists.
Building commissioning is a quality-focused process that begins during design and continues through testing, verification, and occupancy. The process helps to verify that the projectâs systems are planned, designed, installed, tested, operated, and documented to meet the Ownerâs Project Requirements.
The 2010 revisions to the UK building regulations have emphasised
that building services need to be commissioned appropriately to demonstrate their operational effectiveness, as indicated by a Display Energy Certificate (DEC). Commissioning must be a systematic, planned activity from the early design stages to post-occupancy monitoring and warranty monitoring. Several CIBSE documents help define the specific processes and delineate responsibilities, including CIBSEâs Commissioning Code M for air balancing and CCSM for water distribution systems.
Cooling
While it is not a part of every project, building commissioning is often necessary to ensure the performance of complex facilities. This process includes a variety of specific phases and activities that help to verify and document the system design and implementation.
The CxA is an onsite presence throughout construction, working with contractors and witnessing testing to make sure equipment and systems are installed correctly.CxAâs are also able to perform functional performance tests of (972) 818-9000 equipment and systems during the startup phase. This allows them to identify potential problems that would not have been caught during the construction process.
Having a robust building commissioning process is key to seeing the results you expect from your energy and operational costs. Fixing performance issues early in the project is much cheaper than making changes to completed work and maintenance expenses can be avoided by keeping your systems operating efficiently. In addition, research shows that buildings with a thorough commissioning process see a higher return on investment and more savings from their utility bills
