HVAC Equipment!
This piece of HVAC equipment conditions and distributes air to occupied spaces, often through ductwork and terminal units.
What is an AHU (Air Handler Unit)?
These checklists Confirm that equipment is installed, calibrated, and tested for proper operation before FPTs begin
What are Pre-Functional Checklists?
This acronym is the step-by-step procedure used during commissioning to confirm that equipment and systems perform as intended and to their design sequence.
What is an FPT (Functional Performance Test)?
Prepared by the CxA at the end of the project, this comprehensive document includes test results, outstanding issues, and a record of the commissioning process.
What is the Final Commissioning Report?
During functional testing the AHU won't run in economizer mode because the outside air sensor is reading 20° F higher than actual conditions.
What is a faulty (or miscalibrated) outside air temperature sensor?
This component regulates the volume of air delivered to a space, typically in response to thermostat signals.
what is a VAV Terminal Unit (Variable Air Volume Terminal Unit)?
This report certifies that air and water flows meet design.
What is the TAB report?
This acronym Stands for the document that outlines the owner's priorities and performance goals for the project.
What is the OPR (Owner’s Project Requirements)?
This document, prepared at the start of a project, describes the roles, responsibilities, schedule and scope of commissioning activities.
What is the Commissioning Plan?
Outside air dampers look "open" in the BAS but they never move because this piece is loose or disconnected.
What is the Damper Actuator or Damper Actuator Linkage?
This type of HVAC System uses the outside air when conditions are favorable to reduce mechanical cooling demand.
What is an Economizer?
Contractors are encouraged to practice this step by running through the entire FPT script in advance to verify readiness.
What is a Functional Test Rehearsal?
This acronym stands for the centralized system of hardware and software that monitors and controls HVAC Systems and sometimes lighting.
What is the BMS/BAS (Building Management/Automation System)?
This running log, often maintained by the CxA, records deficiencies, open items, and who is responsible for resolving them.
What is the Master Issues Log?
A fan keeps running 24/7 even though the BAS has commanded it "off" because this starter component was manually overridden.
What is the motor starter hand/off/auto (HOA) switch?
or
What is the VFD (Variable Frequency Drive)?
This piece of HVAC equipment removes heat from chilled water using a condenser water loop, often located on the roof or in a mechanical yard.
What is a Cooling Tower?
Once all prerequisites are Complete, the team must submit this formal document notifying the CxA that systems are operationally ready for testing.
What is the Commissioning Readiness Letter?
This Acronym refers to the Contractor's report of the measured air and water flows in a building.
What is the TAB Report (Testing, Adjusting, and Balancing Report)?
Created by the design team, this document translates the Owner’s Project Requirements into technical solutions and serves as a reference throughout commissioning.
What is the BOD (Basis of Design)?
During testing, an air handler can't achieve its design cooling discharge air temperature because this chilled water balancing valve was left fully closed after installation.
What is a Circuit Setter?
This unit type provides silmultaneous chilled water for cooling and hot water for heating by reclaiming condenser heat that would otherwise be rejected. It's often applied in hospitals, laboratories and mixed-use buildings with year-round loads.
What is a Heat Recovery Chiller?
This prerequisite test requires verifying that every BAS input and output is wired, mapped, and responds correctly in the field and at the workstation.
What are Point-to-point Checkouts.
This process uses continuous monitoring of BAS trend data, fault detection, and analytics to identify operational issues and sustain performance improvements over time.
what is MBCx (Monitoring Based Commissioning)?
This document, sometimes required for LEED projects, provides the building operator with systems overviews, sequences, and maintenance frequency schedules?
What is the Commissioned Systems Manual (or Systems Manual)?
During reheat testing, the BMS shows the VAV box is delivering 95°F air, but your temperature sensor reports a value of 72°F, a recalibration on the DAT sensor has been completed and you know it to be accurate, but for this reason it is providing false information.
