ISO 19455-1:2019

This document specifies a planning method for functional performance testing (FPT). This document is applicable to the planning of the FPT during the design phase of new buildings and retrofit projects, which is defined in ISO 16813. This document establishes how to design building environmental systems when the FPT is being carried out. This document defines the following: — what kind of information regarding the system is required (for example, design documents, drawings and product specifications); — what kind of data should be measured (though concrete measurement techniques are not specified in this document); — how the measured data is analysed. Such clear definition of the FPT makes it possible for building designers to prepare and plan for FPT throughout the design process. This document specifies an FPT method for secondary hydronic pump, system and associated controls in heating, ventilation and air conditioning (HVAC) systems.
