9、-09 2 National foreword This document (ISO 16757-1:2015) has been prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works, Subcommittee SC 13, Organization of information about construction works. The responsible German body involved in its preparation was the DIN-Normenauss
10、chuss Heiz- und Raumlufttechnik (DIN Standards Committee Heating and Ventilation Technology), Working Committee NA 041-01-71 GA Gemeinschaftsarbeitsausschuss NHRS/NABau: Produktdaten fr Anlagenmodelle der TGA (SpA ISO/TC 59/SC 13/WG 11). Attention is drawn to the possibility that some of the element
11、s of this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. ISO 16757 consists of the following parts, under the general title Data structures for electronic building services product catalogues: Part 1: Concepts, architect
12、ure and model Part 2: Geometry The following parts are planned: Part 3: Script language and functions Part 4: Cooperation with building information modelling standards Part 5: Product catalogue exchange format DIN ISO 16757-1:2015-09 3 IntroductionThese Content Parts of this International Standard w
13、ill define standardised properties for the product groups and the composition of 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
14、during the planning and design of buildings. The designers in building services 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 an
15、d better documentation to verify the compliance with these requirements. The resulting 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,
16、calculation programs, BIM tools, and management software. The software systems need 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 he
17、ating, ventilation, air conditioning, sanitary). Others provide only certain product 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 te
18、chnical properties required for functional design and calculation (e.g. in the form 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 v
19、isualization (such as photos, video sequences, or acoustical sequences).Additionally, 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
20、 requirements of the planner. Needless to say, that each program contains only the 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 indep
21、endent from the manufacturers. The next problem is that data files from different 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 produc
22、t data and algorithms are automatically available, the calculation and simulation 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 inform
23、ation about their products in the formats of all potential software systems. Thus, we have a typical situation where standardization is required to improve the exchange of information between business partners.DIN ISO 16757-1:2015-09 4Within single product groups (e.g. radiators), national initiativ
24、es to standardize exchange formats have already been conducted. But there is a lack of unification of existing 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 diffe
25、rent data formats and to use different software systems to deal with products of different manufacturers, 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
26、. In addition, to the benefit for planning, there will be an amount of advantages for other software solutions, e.g. facility management and life cycle management.ISO 16757 is a multi-part standard. Future parts will include: an overview of ISO 16757 and the rationale for its elements and organizati
27、on; geometric elements which are used to represent the products in the catalogues of ISO 16757; definition of the script language used in ISO 16757 for various purposes; IDM descriptions for ISO 16757, including process descriptions for those processes which are to be supported by the standard and i
28、t comprises the rules for mapping of product and the property descriptions to IFC and for defining properties semantically with IFD; definition of an exchange format in XML by which electronic catalogues can be exchanged according to the definitions of ISO 16757. The exchange format will be specifie
29、d as an XML Schema Definition (XSD).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.DIN ISO 16757-1:2015-09 5 1 ScopeThe primary pu
30、rpose 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 software applications. This includes a meta model for the specification of product classes and their pr
31、operties 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 areas: Basic concepts like conceptual models, languages, geometry representations, and XML schemas for
32、 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 product groups of building services concrete models for the description and the exchange of products.
33、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 to identify the appropriate product variant from a parametric electronic catalogue; resources for th
34、e specification of dependent properties and their computational functions to compute their values in dependency from installation parameters; resources for the specification of composition relationships between products which can be used to model structures like bill of materials or accessory relati
35、onships; resources for a parametric constructed solid geometry (CSG) based geometry representation containing specific CSG elements geometrical elements which are typical for building services products.This part of ISO 16757 specifies the underlying concepts, a generic model specifying the available
36、 modelling elements and their relationships, and a framework for the specification of the Content Parts by describing the elements which are to be provided by these Parts.Not in scope of this part of ISO 16757 are the following: a detailed description of the used geometrical primitives;NOTE Geometry
