ISO/IEC TR 14543-4:2002 情報技術—ホームエレクトロニックシステム（HES）アーキテクチャ—パート4：多目的ビルにおけるホームオートメーションとビルディングオートメーション | ページ 2

FOREWORD

• 1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) formthe specialized system for worldwide standardization. National bodies that are members of ISO or IECparticipate in the development of International Standards through technical committees established by therespective organization to deal with particular fields of technical activity. ISO and IEC technical committeescollaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,in liaison with ISO and IEC, also take part in the work.
• 2) In the field of information technology, ISO and IEC have established a joint technical committee,ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to nationalbodies for voting. Publication as an International Standard requires approval by at least 75 % of the nationalbodies casting a vote.
• 3) Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject ofpatent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC and ISO technical committees is to prepare International Standards. Inexceptional circumstances, a technical committee may propose the publication of a technicalreport of one of the following types:

• • type 1, when the required support cannot be obtained for the publication of an InternationalStandard, despite repeated efforts;
• • type 2, when the subject is still under technical development or where, for any otherreason, there is the future but not immediate possibility of an agreement on an InternationalStandard;
• • type 3, when the technical committee has collected data of a different kind from that whichis normally published as an International Standard, for example ‘state of the art’.

Technical reports of types 1 and 2 are subject to review within three years of publication todecide whether they can be transformed into International Standards. Technical reports oftype 3 do not necessarily have to be reviewed until the data they provide are considered to beno longer valid or useful.

ISO/IEC TR 14543-4, which is a technical report of type 2, was prepared by subcommittee 25:Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:Information technology.

This publication was drafted in accordance with the ISO/IEC Directives, 2.

This document is issued in the type 2 technical report series of publications (according to15.2.2 of the Procedures for the technical work of ISO/IEC JTC 1 (1998)) as a prospectivestandard for provisional application in the field of the Home Electronic System (HES), becausethere is an urgent requirement for guidance on how standards in this field should be used.

This document is not to be regarded as an International Standard. It is proposed for provisionalapplication so that information and experience of its use in practice may be gathered.Comments on the content of this document should be sent to IEC Central Office.

A review of this type 2 technical report will be carried out not later than three years after itspublication with the option of extension for a further three years of either conversion into anInternational Standard or withdrawal.

ISO/IEC TR 14543, Information technology — Home Electronic system (HES) architecture consists of four parts:

• Part 1: Introduction
• Part 2: Device modularity
• Part 3: Communication layers
• Part 4: Home and building automation in a mixed-use building

INTRODUCTION

This technical report explores the similarities and differences between home and buildingcontrol systems in an environment where both home and building control interact, namely, amixed-use residential/commercial building.

A logical model for linking building and home control systems is specified. Models showing theorganization of application domains, such as energy management and lighting, are included.The option of managing an application domain with a single application controller versus aFully Distributed System is considered.

Methods for overall building management are presented. The interaction of building and homecontrol systems requires a demarcation between building manager versus tenantresponsibilities, as explained in this document. A method for implementing agreementsbetween building managers and tenants regarding user access to and control of applicationsvia a firewall is specified.

1 Scope

This part of ISO/IEC 14543 presents methods for overall building management of the homeelectronic system (HES) architecture. The interaction of building and home control systemsrequires a demarcation between building manager versus tenant responsibilities. A method forimplementing agreements between building managers and tenants regarding user access toand control of applications via a firewall is specified.

This technical report augments series ISO/IEC 14543, the architecture of HES (HomeElectronic System), in order to accommodate both home and building automation in a mixedusebuilding. Both systems may coexist in a building with shops, offices and apartments. Somesystems are applicable to the whole building versus the systems which are applicable toindividual apartments and offices only. In some cases these systems need to interact.

This technical report proposes a logical model for linking building and home control systemseven if the two use different physical arrangements of components. The basic recommendationsare:

• • allow for distinct and separate building and home automation control systems, possiblysupplied by different manufacturers;
• • define clear points of connection between building and home control systems;
• • limit the number of points of connection between building and home control systems,preferably to one per home system;
• • accommodate systems that provide building tenants with user control of local systems. Thisfavors an architecture where products can be designed for the user to override controldecisions within parameters agreed with building management. Such actions are exercisedby the building automation system and affect local systems. This enhances user safety anduser privacy;
• • provide seamless links between systems that are based on different architectures, thatincorporate different communications protocols, and that may be purchased from differentmanufacturers.
