Re Commissioning: An application of the commissioning process to a project that has previously been commissioned. Once a facility has been commissioned (either as a new building or EBCx), than the next commissioning event would correctly be called Re Commissioning.
Ongoing Commissioning (OCx): a continuation of the Cx Process after the Hand-Off Phase to verify that a facility continues to meet current and evolving CFR (OPR for new construction). OCx Process Activities occur throughout the life of the facility; some of these will be close to continuous in implementation and others will be either scheduled or unscheduled (as needed).
Benefits of OCx:
EBCx Services offers various cost effective approaches to OCx, ranging from monthly or quarterly review of utility data, to remote analysis of the Building Automation System (BAS).
A key step in the EBCx process is obtaining critical operating measurements to establish a baseline of equipment and system performance.
Benefits of EBCx:
Technical Commissioning: is a quality focused approach for new construction and major remodeling projects, assures that a project is properly constructed and operates according to the Owners Project Requirements (OPR). The approach focuses upon verifying and documenting that the facility and all of its systems, components and assemblies are planned, designed, installed, tested, and can be operated and maintained to meet the OPR.
Benefits of Technical Commissioning:
EBCx Services is certified by NEBB in Whole Building Systems Technical Commissioning.
Existing Building Commissioning (EBCx) also known throughout the industry as Retro Commissioning (RCx), is a quality-focused approach for attaining the Current Facility Requirements (CFR) of an existing building and/or its systems and assemblies.
Simply stated, EBCx is a process that makes existing buildings perform at their maximum level towards achieving the CFR, using exiting equipment and systems. EBCx is analogous to tuning up a car, with the goal of achieving improved performance and gas mileage. The EBCx process includes performing minor repairs that are necessary to improve equipment operation, then optimizing systems to achieve maximum performance towards achieving the CFR. A key componenet of EBCx is achieving the CFR at the lowest possible energy cost.
The EBCx process focuses on planning, investigating, implementing, verifying, and documenting that the facility and/or its systems and assemblies are operated and maintained to meet the CFR, with a program in place to maintain the enhancements for the remaining life of the facility. EBCx Services performs a technical process of improving building systems by inspecting, testing, analyzing, calibrating, repairing, adjusting and optimizing building systems, and training operators for the purpose of improving building performance.
EBCx should not be confused with energy audits. The main difference between EBCx and an energy audit is the Current Facility Requirements (CFR). With EBCx, the CFR drives the project by identifying what the current needs of the facility are, which may be drastically different than what the original needs and design were when the facility was constructed. With energy audits, reducing energy consumption and costs drives the project.
EBCx Services provides an ASHRAE Level 2 energy audit as part of our EBCx process. Due to the information that is obtained during the EBCx process, it is extremely economical to provide an ASHRAE Level 2 energy audit as part of the EBCx process.
EBCx Services is certified by NEBB in Technical Retro-Commissioning of Existing Buildings.
The Building Automation System (BAS) is critical during every type of Commissioning. The BAS is a flashlight into the systems of a building. Leveraging the BAS allows for inspections to be made in a cost effective manner.
