Overview

CLC/TR 50491-6-3:2011 defines rules for assessing and classifying Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) installations by their complexity and energy performance. The Technical Report applies to household HBES from the utility connection point, including new installations, retrofits and enlargements, and covers the interconnection networks regardless of transmission media (power-line, dedicated cabling, wireless or telecom networks). It supports consistent assessment of HBES installations for planning, verification and energy-management objectives.

Key topics and requirements

• Classification by transmission media (power line, dedicated cable, wireless, telecommunication), topology (centralised, distributed, hybrid) and HBES complexity level (Basic, Intermediate, High).
• HBES levels expressed as a two‑digit code: first digit = complexity (1/2/3), second digit = energy performance (A–D) aligned with EN 15232.
  • Complexity thresholds are based on a points system (see Table 1) and minimum numbers of applications/clusters:
    • Basic (1X): ≥15 points, ≥3 applications, ≥2 clusters
    • Intermediate (2X): ≥35 points, ≥3 applications, ≥3 clusters
    • High (3X): ≥53 points, ≥6 applications, all four principal clusters
• Energy performance classes (A–D) reference EN 15232; achieving A requires implementing relevant energy-management applications.
• Terms and definitions for actuators, nodes, HBES devices/systems, clusters (energy management, security, comfort, communications, plus AV/IT) and power-line communication are standardized.
• Requirements for installations and devices, and procedures for verification and commissioning, are specified to ensure consistent assessment and interoperability.
• Includes an informative annex with application examples and a points table mapping devices/applications (fire, intrusion, HVAC, blind control, video surveillance, etc.) to clusters.

Applications (practical value)

• Use for project planning and specification of HBES/BACS in residential and small commercial buildings.
• Assessment tool to:
  • classify existing systems for retrofit prioritization,
  • benchmark installations for energy‑saving upgrade paths,
  • support procurement and tender documents (specifying a target HBES level).
• Helps system integrators and installers define scope, interoperability and verification checkpoints during commissioning.
• Useful for architects, energy managers and facility owners to align automation design with energy-performance targets.

Who should use this standard

• HBES installers and integrators
• Building automation designers and system architects
• Energy managers and sustainability consultants
• Manufacturers and product specifiers
• Building owners, facility managers and regulators

Introduction
HBES are based on the integrated control of the components of an installation, and the clusters for HBES
include the following:
– energy management;
– security;
– comfort;
– communication from and to the system through external telecommunication networks
Due to the increasing bandwidth in the telecommunication networks, the number of functions that can be
provided by HBES systems, related to the clusters mentioned above, has increased. Additional clusters are
audio/video and information technology.
The system control networks, i.e. dedicated cable, power line communication or radio-frequency, should be
installed in relation with the existing networks, i.e. electricity, telephone and TV, according to the installation
rules defined for the respective control networks, to minimise perturbations of the system.
