The work of pre
13、paring International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in
14、 liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC
15、 Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility th
16、at some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent d

21、 the technical data model. Furthermore, they determine the specific programming function-interfaces to layout, calculate, and simulate the products.There is a growing need for information about building services systems during the planning and design of buildings. The designers in building services
22、have to execute detailed calculations and simulations to ensure saving of energy and to satisfy hygienic and comfort criteria in heating, ventilation, air conditioning, and sanitary plants. They have to provide better and better documentation to verify the compliance with these requirements. The res
23、ulting designs have to describe the complete plants without internal interference or intersection with the building.These requirements can only be achieved with modern engineering applications like CAD- and CAE-systems, calculation programs, BIM tools, and management software. The software systems n
24、eed exact data of the used plant components. Each component contributes to the performance data of the whole building.There are many manufacturers, who provide products to certain sectors of building services (such as heating, ventilation, air conditioning, sanitary). Others provide only certain pro
25、duct groups (radiators, heaters, air condition equipment, air pipes, valves, devices).Classical catalogues provide product data in tables and show the design algorithms in diagrams and design rules. In addition to the technical properties required for functional design and calculation (e.g. in the f
26、orm of curve diagrams), such catalogues also contain the geometry data needed for dimensional design and construction (e.g. in the form of dimensional drawings with port details) and the descriptive objects serving for visualization (such as photos, video sequences, or acoustical sequences).Addition
27、ally, nearly all big manufacturers provide their own software (mostly for free) as electronic catalogues to select, to design, and to calculate their products.Unfortunately, none of these software solutions meets all the requirements of the planner. Needless to say, that each program contains only t
28、he product range of its manufacturer. So it is not possible to perform a continuous planning of the plant with products of different manufacturers.Thus, it is desirable to provide engineering applications which are independent from the manufacturers. The next problem is that data files from differen
29、t manufacturers if available at all are organized in different data formats, structures, and terminologies.Independent CAD-systems and calculation software need to get data and algorithms in a uniform way. Only if product data and algorithms are automatically available, the calculation and simulatio
30、n of a complete HVAC plant is possible.Software providers cannot afford to provide all data from all product manufacturers in the format required by their system. Also, product manufacturers cannot provide current information about their products in the formats of all potential software systems. Thu
31、s, we have a typical situation where standardization is required to improve the exchange of information between business partners.Within single product groups (e.g. radiators), national initiatives to standardize exchange formats have already been conducted. But there is a lack of unification of exi
32、sting formats across all product groups.Required is a uniform, internationally standardised definition for product catalogue data interchange.Such a definition eliminates the need to manage different data formats and to use different software systems to deal with products of different manufacturers,
33、 and this leads to a significant reduction of costs for manufacturers and users. Integrating this data into BIM-systems (Building Information Modelling) allows data interchange between IT systems. In addition, to the benefit for planning, there will be an amount of advantages for other software solu
34、tions, e.g. facility management and life cycle management.This International Standard offers for the first time an interface which allows the uniform handling of data about technical, commercial, maintenance, service, as well as geometry, images, video, and text information.

38、oduct catalogues for building services Part 1: Concepts, architecture and model1 ScopeThe primary purpose of this International Standard is the provision of data structures for electronic product catalogues to transmit building services product data automatically into models of building services sof
39、tware applications. This includes a meta model for the specification of product classes and their properties and a meta model for the product data which is exchanged in product catalogues. Product data has to follow the specifications for their product groups.The standard series is split into two ar
40、eas: Basic concepts like conceptual models, languages, geometry representations, and XML schemas for data exchange are provided in the Conceptual Parts of the standard series (Parts with a one digit number). Using these resources, the Content Parts of this International Standard define for various p
41、roduct groups of building services concrete models for the description and the exchange of products.The basic concepts which are provided by the standard series include the following: resources for the specification of selection properties and a selection property tree guiding the selection process
42、to identify the appropriate product variant from a parametric electronic catalogue; resources for the specification of dependent properties and their computational functions to compute their values in dependency from installation parameters; resources for the specification of composition relationshi
