The work of preparing International Standards is normally carried out through
8、 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 liaison with ISO, also take part in the work. ISO collaborate
9、s closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards
10、. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this
11、 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15928-5 was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works, Subcommittee SC 15, Performance description of houses. ISO 15928 consists
12、of the following parts, under the general title Houses Description of perfomance:Part 1: Structural safetyPart 2: Structural serviceabilityPart 3: Structural durabilityPart 4: Fire safetyPart 5: Operating energyiv ISO 2013 All rights reserved ISO 15928-5:2013(E) Introduction This part of ISO 15928 i
13、s one of a series of standards titled Houses Description of performance. The objective of the ISO 15928 series is to identify the methods that will be used to describe the performance of houses. The ISO 15928 series is confined to buildings occupied for residential purposes that may be separated or
14、linked horizontally, but not linked vertically, and which have their own access and do not share any common space. Each part of ISO 15928 relates to a separate attribute. The parts of ISO 15928 do not specify levels of performance and they are not intended to replace national standards or regulation
15、s, but provide a standardized framework to be used for development of national standards and regulations consistent with World Trade Organization (WTO) requirements. The parts of ISO 15928 do not provide design methods and/or design criteria. Based on the framework provided by the ISO 15928 series,
16、purchasers, regulators and standards- preparers in respective countries can describe their requirements in standardized performance terms, as appropriate. Additionally, the manufacturers/providers can respond by describing the performance of their products in a similar manner. The purpose of this pa
17、rt of ISO 15928 is to provide a standardized system of describing performance that can be used to specify performance requirements and performance levels, or to rate houses, in terms of operating energy. NOTE The WTO Agreement on technical barriers to trade, Clause 2.8, states: “Whenever appropriate
18、, members shall specify technical regulations based on product requirements in terms of performance, rather than design or descriptive characteristics.” ISO 2013 All rights reserved v Houses Description of performance Part 5: Operating energy 1 Scope This part of ISO 15928 sets out a method for desc
19、ribing the operating energy performance of houses. It covers user needs, provides performance descriptions and outlines evaluation processes. It includes the description of relevant parameters for external and internal climatic conditions, user functional requirements, energy used by the house and e
20、nergy generated by the house. T his par t of ISO 15928 is intended to be used for houses that may be separated from, or linked horizontally to, another house(s). Where houses are linked, and some sharing of services occurs, it is intended that energy usage performance may be assessed both for indivi
21、dual houses, as well as a group of houses that are linked together. The ISO 15928 series is intended for use in the evaluation of the design and construction of houses and in the international trading of houses or their sub-systems. The ISO 15928 series does not specify a level of performance and it
22、 is not intended to provide a design method and/or criteria. NOTE Structural performance and other attributes are covered in other parts of ISO 15928. 2 Normative references The following referenced documents are indispensable for the application of this document.

37、t-in appliances, e) the consumption of energy being excessive, and f) the depletion of non-renewable energy resources being excessive NOTE 1 Built-in appliances are appliances that are fixed in place that cannot be removed or replaced easily. Typical examples are lighting and domestic hot water, but
38、 could also include other items such as stove and refrigeration unit. NOTE 2 For the purpose of this part of ISO 15928, durability is not considered to have a bearing on the operating energy performance of a house. 4.3 Principles for describing operating energy performance The operating energy perfo
39、rmance of the house can be described by the energy consumed under normal use in relation to: a) external climatic environment of the house, ISO 2013 All rights reserved 3 ISO 15928-5:2013(E) b) indoor conditions to be maintained, c) user functional requirements, including actions resulting from the
40、number and individual characteristics of the occupants of the house, and d) types of the energy to be supplied and their purposes. 5 Parameters for the description of performance 5.1 Parameter for describing the external climatic environment of the house The parameter for describing the actions and
41、agents resulting from external climatic environment of the house is its geographical location. NOTE For example of the type of climate related data and procedures that may be appropriate for use in describing the external environment, see ISO 13790. 5.2 Parameters for describing the indoor condition
42、s The parameters for describing the indoor conditions are: a) specified range of indoor temperature, b) specified range of indoor humidity, and c) specified level of ventilation. 5.3 Parameters for describing the user functional requirements The parameters for describing the user functional requirem
43、ents are: a) amount of hot water supplied at a given temperature, b) amount and level of lighting provided, c) relevant parameters for any other functional requirements, and d) the number and individual characteristics of the occupants of the house. 5.4 Parameters for describing energy used The para
44、meter for describing the amount of energy used is the megajoule (MJ) or kilowatt hour (kWh) (1 kWh = 3,6 MJ) per appropriate unit of consumption (time, capita, area, volume, etc.). 5.5 Parameters for describing the energy generated by the house The parameters for describing the energy generated from
45、 features that form an integral part of the house are the type and the ratio of that energy to the total energy consumed by the house. 6 Evaluation 6.1 General Evaluation may be carried out by: a) analysis, b) testing,4 ISO 2013 All rights reserved ISO 15928-5:2013(E) c) service experience, or d) a
46、combination of the above. Adequate detailed information shall be provided to allow the evaluation to be carried out. The evaluation shall take account of the situation where the houses are linked and services relating to operating energy are shared and shall report the outcomes accordingly. 6.1.1 An
47、alysis Whether the energy performance criteria are satisfied can be determined by an analysis of the trial design. Analysis will involve consideration of climatic conditions and occupant characteristics, along with the activities undertaken by occupants. Analysis in regards to type(s) and amount(s)
48、of renewable and/or non-renewable energy consumed will also be needed. 6.1.2 Testing Testing of specific services/building elements shall incorporate a realistic representation of materials, operational conditions, and construction practices. 6.1.3 Service experience Service experience shall compris
