Standards Development
This standard specifies a planning method for functional performance testing (FPT) when undertaking commissioning as specified in ISO 24359-1. FPT is the process conducted to verify that commissioned systems perform in accordance with the owner’s project requirements (OPR), with procedures developed by the commissioning provider or other responsible parties.
This standard specifies an FPT planning method for air-handling unit (AHU) fans, systems, and associated controls in heating, ventilation and air-conditioning (HVAC) systems. In particular, this standard defines:
- what information regarding the system shall be documented (e.g. design documents, drawings, and product specifications);
- what data shall be measured (concrete measurement techniques are not specified in this document);
- how the measured data shall be analysed to confirm that the OPR has been met.
By clearly defining these elements, this standard enables commissioning providers to prepare and plan FPT effectively and to ensure the reliable execution of high-quality tests.
To achieve both effective energy savings and enhanced indoor environmental quality in HVAC systems, which account for a significant share of building energy consumption, it is essential not only to introduce advanced energy-efficient technologies but also to verify through testing and adjustments that the system operates in accordance with the design intent.
To ensure such tests are reliably executed and to deliver high-quality buildings, it is essential to apply commissioning from the early stages of a project and to prepare a concrete plan for functional performance testing (FPT). For an effective plan to be developed, it is necessary to define what information about the system shall be documented, what data shall be measured, and how the measured data shall be analysed to confirm compliance with the owner’s project requirements (OPR).
The proposed standard specifies these essential definitions for FPT, thereby enabling commissioning providers to prepare and plan FPT effectively and to ensure the reliable execution of high-quality tests.
