Overview
SIST-TP CEN/TR 17689-1:2026 establishes a general framework and procedure for the quality and performance assessment of Building Automation and Control (BAC) control loop components in individual zone control. Developed under the guidance of the European Committee for Standardization (CEN) and aligned with key European directives, this Technical Report is central to improving the efficiency, comfort, and functionality of modern building environments. By promoting clarity and consistency across component standards, the document facilitates the transparent selection and evaluation of BAC components-paving the way for increased energy savings and enhanced building performance.
Key Topics
- General Framework: Outlines a systematic approach for classifying and testing BAC control loop components.
- Component Coverage: Focuses on sensors, valves, and actuators used in electronic individual zone control equipment.
- Quality and Performance Criteria: Specifies assessment methods to ensure reliability, compatibility, and efficiency in BAC systems.
- Interchangeability: Provides rules and guidelines for combining certified components, supporting system flexibility.
- Reference Standards: Integrates a suite of relevant standards to foster harmonized assessment and compliance within the industry.
Applications
The procedures set out in SIST-TP CEN/TR 17689-1:2026 are vital to a wide array of building automation and control scenarios. Key application areas include:
- Heating, Ventilation, and Air Conditioning (HVAC): Ensures optimal operation and control accuracy for systems such as radiator heating, floor heating, ceiling systems, fan coil units, variable air volume systems, electric convectors, and chilled beam systems.
- Electronic Individual Zone Control: Facilitates precise temperature regulation in specific building zones, contributing to enhanced occupant comfort and energy efficiency.
- Energy Performance Certification: Supports compliance with the EU Building Energy Performance Directive (EPBD), which requires proof of energy saving and efficient operation in new and existing buildings.
- Replacement and Upgrading: Enables system designers and facility managers to confidently select and replace BAC components, assured by transparent quality and interoperability requirements.
Related Standards
For robust BAC implementation and compliance, SIST-TP CEN/TR 17689-1:2026 references and aligns with several key standards, including:
- EN ISO 7345: Defines physical quantities and terms relevant to thermal performance in buildings.
- ISO 52000-1: Provides an overarching framework and procedures for energy performance assessment.
- EN 15500-1 and CEN/TR 15500-2: Cover electronic individual zone control equipment and accompanying technical guidance, forming a foundation for BAC system assessment.
- EN 12098-1 and EN 12098-3: Address controls for hot water and electric heating systems.
- EN 17690-1: Details requirements for room temperature sensors in BAC control loops.
- EN 17691-1: Specifies requirements for valve and actuator assemblies used in water-based HVAC applications.
By adhering to these established standards, system integrators, manufacturers, and building professionals can ensure that BAC control loop components meet industry best practices for energy efficiency, interoperability, and performance.
BAC control loop components and their quality assessment drive the evolution of intelligent, energy-efficient buildings. SIST-TP CEN/TR 17689-1:2026 offers a solid foundation for consistent evaluation, supporting sustainable building automation throughout Europe and beyond.
