The work of preparing 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 liaison with ISO, also take part in the work. ISO collaborates 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. 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 13790 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment. Subcommittee SC 2, Calculation methods, in cooperation with CEN/TC 89, Thermal performance of buildings and building components.This second edition cancels and replaces the first edition (ISO 13790:2004), which has been technically revised. A summary of the principal changes is given below. Throughout, statements and equations that were true only for the heating mode have been amplified to accommodate both heating and cooling modes.Throughout, all texts that applied only for monthly or seasonal calculations have been amplified to accommodate hourly as well as monthly and seasonal calculations. The structure has been adapted to maximize the common use of procedures, conditions and input data, irrespective of the calculation method. A monthly (and seasonal) method for cooling, similar to the method in the first edition for heating, has been added.一 A simple hourly method for heating and cooling, to facilitate direct introduction of hourly, daily or weekly patterns (e.g. controls, user behaviour), has been added. For dynamic simulation methods, procedures that are consistent with the boundary conditions and input data for the seasonal, monthly and simple houriy methods have been added for the boundary conditions and input data. The whole document has been scrutinized to check its applicability within the context of building regulations, which require a minimum of ambiguities and subjective choices; where needed, possibilities are offered for national choices as given in national annexes, national building codes or national standards referring to this document, depending on the purpose/application of the calculations as detailed in this list and on the type or complexity of the building.IntroductionThis standard provides the means (in part) to assess the contribution that building products and services make to energy conservation and to the overall energy performance of buildings.This International Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD(26l). It forms part of a series of standards aimed at European harmonization of the methodology for the calculation of the energy performance of buildings. An overview of the whole set of standards to support the EPBD is given in CEN/TR 15615【28】. See also Annex A.This International Standard is one of a series of calculation methods for the design and evaluation of thermal and energy performance of buildings. It presents a coherent set of calculation methods at different levels of detail, for the energy use for the space heating and cooling of a building, and the influence of the recoverable thermal losses of technical buildings systems such as the heating and cooling system.In combination with other energy performance-related standards (see Figure 1, which gives an outline of the calculation procedure and its links with other energy performance-related standards), this International Standard can be used for the following applications:a) judging compliance with regulations expressed in terms of energy targets (via the design rating; see Annex A);b) comparing the energy performance of various design alternatives for a planned building;c) displaying a standardized level of energy performance of existing buildings (the standard calculated rating; see Annex A);d) assessing the effect of possible energy conservation measures on an existing building, by calculation of the energy use with and without the energy conservation measure; see Annex A;e) predicting future energy resource needs on a regional, national or international scale, by calculating the energy use of typical buildings representative of the building stock.References are made to other International Standards or to national documents for input data and detailed calculation procedures not provided by this International Standard.The main inputs needed for this International Standard are the following: transmission and ventilation properties; heat gains from internal heat sources, solar properties;climate data; description of building and building components, systems and use; comfort requirements (set-point temperatures and ventilation rates); data related to the heating, cooling, hot water, ventilation and lighting systems:一 partition of building into different zones for the calculation (different systems may require different zones); energy losses dissipated and recoverable or recovered in the building (internal heat gains, recovery of ventilation heat loss);airflow rate and temperature of ventilation supply air (if centrally pre-heated or pre-cooled) and associated energy use for air circulation and pre-heating or pre-cooling：controls.The main outputs of this International Standard are the following: annual energy needs for space heating and cooling; annual energy use for space heating and cooling; length of heating and cooling season (for system running hours) affecting the energy use and auxiliary energy of season-length-dependent technical building systems for heating, cooling and ventilation.Additional outputs are the following: monthly values of energy needs and energy use (informative); monthly values of main elements in the energy balance, e.g. transmission, ventilation, internal heat gains, solar heat; contribution of passive solar gains; system losses (from heating, cooling, hot water, ventilation and lighting systems), recovered in the building.心点hts reservedProvtoed by iHS under kcerse with ISONo reproduction or networkng permtted without bcense trom IHSNotfor Re&ateISO 13790:2008(E)© ISO 2008 - All rights reservedCop/roht I心naional Ooanoaion kxProvided by IHS under kcerse with ISONo reproduction or networkng permtted bcense horn IKSNotfor Re&ateAssessment of overall energy use anddefinition of energy ratingsDelivered energy for heating andcooling, per energy carrierDelivered energy for hot water,lighting and ventilation systemand (de -)humidification, perenergy carrierISO 13790Climate dataPropertiess6.Ep=nq Buns*ssEnergy use for heating and coolingSimple hourlyI Monthly (or seasonal)DynamicsimulationThree (national) options for calculation ofbuilding energy needs for heating and coolingDynamic parametersSolar and internal heat sourcesVentilation and transmission heat transferPartitioning of building into zones for calculation,including system criteriaZoning rules, building partSpecified indoor conditionsTransmission properties (ISO 13789)Air flow/infiltrationSolar properties-H+ Jll -ill IIPropertiesProject data (building, systems, use,surroundings, location)External climate data (ISO 15927-4)Data for existing buildingsProject dataClimate dataNon -recoverable thermal losses from technical systems;
