Foreword
This International Standard (EN ISO 16484-3:2005) has been prepared by Technical Committee CEN /TC 247,
"Building Automation, Controls and Building Management", the secretariat of which is held by the SNV, in
collaboration with ISO/TC 205 "Building Environment Design".
This International Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at
the latest by January 2006.
The EN ISO 16484-3 is part of the EN ISO 16484 series of International Standards under the general title
Building Automation and Control Systems (BACS), which will comprise the following parts:
Part 1: Overview and definitions
Part 2: Hardware
Part 3: Functions
Part 4: Applications
Part 5: Data communication protocol

Introduction
This series of standards is intended for design of new buildings and retrofit of existing buildings for an acceptable
indoor environment, practical energy conservation, and efficiency.
The application of this series of standards for BACS is envisaged as follows:
- the environmental design for all building types requires complex methods for automation and control. The
functional integration of services other than HVAC is a general task for all parties employed to develop an
integrated multi-application system. The Integration comprises, e.g. lighting and electric power distribution
control, security control, transportation, maintenance management, or facilities management. This system
integration allows the user to take advantage of synergies between the different applications. This standard will
give guidance to architects, consultants, and contractors as well as to users on how to share such resources;
- the innovation cycles between devices, systems, and networks vary. To make it possible to add and to change
existing devices, and extend the building automation and control network, several interfaces both proprietary and
standardized are defined between the BACS network and the other systems. A manufacturer can design a
product, both to meet hi
