PD CEN/TR 15316-6-6:2017CEN/TR 15316-6-6:2017 (E) 5 Introduction The set of EPB standards, technical repor

23、ts and supporting tools In order to facilitate the necessary overall consistency and coherence, in terminology, approach, input/output relations and formats, for the whole set of EPB-standards, the following documents and tools are available: a) a document with basic principles to be followed in dra

24、fting EPB-standards: CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB standards 1; b) a document with detailed technical rules to be followed in drafting EPB-standards; CEN/TS 16629:2014, Energy Performance of Buildings - Detailed Technical Rules for the set o

25、f EPB-standards 2; c) the detailed technical rules are the basis for the following tools: 1) a common template for each EPB-standard, including specific drafting instructions for the relevant clauses; 2) a common template for each technical report that accompanies an EPB standard or a cluster of EPB

26、 standards, including specific drafting instructions for the relevant clauses; 3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate the correctness of the EPB calculation procedures. Each EPB-standards follows the basic principles and the detailed technical rul

27、es and relates to the overarching EPB-standard, EN ISO 52000-1 17. One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations directly refer to the EPB-standards and make compliance with them compulsory. This requires that the set of EPB-standards consists o

28、f a systematic, clear, comprehensive and unambiguous set of energy performance procedures. The number of options provided is kept as low as possible, taking into account national and regional differences in climate, culture and building tradition, policy and legal frameworks (subsidiarity principle)

29、. For each option, an informative default option is provided (Annex B). Rationale behind the EPB technical reports There is a risk that the purpose and limitations of the EPB standards will be misunderstood, unless the background and context to their contents and the thinking behind them is explaine

30、d in some detail to readers of the standards. Consequently, various types of informative contents are recorded and made available for users to properly understand, apply and nationally or regionally implement the EPB standards. If this explanation would have been attempted in the standards themselve

31、s, the result is likely to be confusing and cumbersome, especially if the standards are implemented or referenced in national or regional building codes. Therefore each EPB standard is accompanied by an informative technical report, like this one, where all informative content is collected, to ensur

32、e a clear separation between normative and informative contents (see CEN/TS 16629 2): to avoid flooding and confusing the actual normative part with informative content, to reduce the page count of the actual standard, and PD CEN/TR 15316-6-6:2017CEN/TR 15316-6-6:2017 (E) 6 to facilitate understandi

33、ng of the set of EPB standards. This was also one of the main recommendations from the European CENSE project 19 that laid the foundation for the preparation of the set of EPB standards.

The methods one to three refer to solar thermal applications and the

39、methods four to six refer to photovoltaic applications. 5.2 Solar thermal methods Method 1 is used for solar thermal applications if (only) system test data according to EN 12976-2 is available. This is commonly the case for solar system types for which the component specifications cannot be determi

40、ned separately. An example of this is a so called Integrated Collector Storage system (= ICS). The system test result, the annual performance of the system, for the actual climate conditions is interpolated to the actual heat demand. Optionally the annual performance is distributed over the month, u

41、sing the distribution of the solar irradiance on the collector plane as the key. The method 1 is limited to the generation of heat for the service domestic hot water production. PD CEN/TR 15316-6-6:2017CEN/TR 15316-6-6:2017 (E) 8 Method 2 is used for solar thermal applications if component specifica

42、tions for the collector and heat storage are available. This is commonly the case for solar thermal for intended use in buildings. Examples of this are solar domestic hot water systems and combi-systems. The method 2 applies the so called Fchart method 3 to calculate the monthly performance using th

43、e component specifications and system design parameters as input. The method 2 is applicable for the services water heating and space heating. The method 2 is intended for use with a monthly time step. Method 3 is used for solar thermal applications if component specifications for the collector and

44、heat storage are available. Method 3 applies an hourly numerical calculation method to determine the solar loop output to the storage tank. The method 3 is intended to be used in combination with EN 15316-5. The combination of the two methods is applicable for the services water heating and space he

45、ating. 5.3 Photovoltaic applications 6 Method description 6.1 Solar thermal applications 6.1.1 Method 1 monthly, using system test data 6.1.1.1 General The effect of a thermal solar system on the energy performance of a building comprises of: heat output to the distribution systems for domestic hot

46、water, thus reducing the buildings consumption of other (e.g. conventionally generated) heat; recovered losses used for space heating, thus reducing the buildings consumption of heat for space heating; electricity to be supplied, thus increasing the buildings consumption of electricity; reduction of

47、 operation time of the conventional heating generator. In some cases, the conventional back-up heater can be turned off during summer, thus reducing stand-by thermal losses and auxiliary electricity consumption. 6.1.1.2 Rationale Method 1 uses system test data for the product technical input data. T

48、he system test data are derived from a test result according to EN 12976-2 or according to EN 12977-2. The test method following EN 12976-2 consists of two steps: 1. system test; The goal of the system test is to determine the whole system performance parameters determined from dynamic operating con

49、ditions. 2. annual performance calculation. The performance parameters are combined with a simplified, standardized, calculation model to calculate the performance for (e.g.) one year for specific reference climate and heat use conditions. Method 1 requires two sets of the annual performance for the climate conditions applicable. One for a lower or equal and one with a higher heat use than applicable. By means of linear interpolation the annual performance for the applicable heat use is derived from these results. P
