IEC 63044-1:2017

Overview

IEC 63044-1:2017 (consolidated as Edition 1.1 with Amendment 1, 2021) defines the general requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS). As Part 1 of the IEC 63044 product-family standard, it provides the framework and high-level scope for devices and networks used in home automation and building automation - including operator stations, management devices, control and application-specific controllers, field devices and their interfaces, plus cabling and interconnection within dedicated HBES/BACS networks.

Key topics and technical requirements

• Scope and applicability: Applies to HBES/BACS products and systems intended for monitoring, control and management across building services and home electronic systems.
• Compliance model: A product claiming IEC 63044 compliance must meet all applicable parts of the series and declare specific part compliance in documentation.
• Standardization structure: Describes the series parts and their focus areas:
  • Part 2 - Environmental conditions (device environments, storage, transport)
  • Part 3 - Electrical safety requirements (safety of network and interfaces)
  • Part 4 - Functional safety (requirements for distributed functions)
  • Part 5 - EMC requirements (overall EMC framework plus Part 5‑1, 5‑2, 5‑3 for different environments)
  • Part 6 - Planning and installation (installation, cabling topologies and rules)
• Interoperability & interfaces: Defines terms like network, gateway, interface and interoperability to support integration of diverse physical layers and application protocols.
• Covered technical areas: electrical safety, functional safety, environmental conditions, EMC, installation and cabling rules/topologies.

Practical applications and who uses it

IEC 63044-1 is essential for:

• Manufacturers designing HBES/BACS hardware (controllers, sensors, operator stations) to ensure they fit the family of product standards.
• System integrators and installers implementing smart home, commercial building or industrial-light automation systems to follow cabling, topology and interface expectations.
• Specifiers, architects and consultants drafting requirements for HVAC, lighting, shading, security and energy management projects.
• Test labs and certification bodies assessing compliance with the IEC 63044 series.
• Building owners and facility managers seeking interoperable and safe building automation solutions.

Typical use cases include smart home automation, multi-application building control (HVAC, lighting, alarms), and networked device ecosystems where EMC, safety, and environmental robustness are required.
