PD CEN/TR 15459-2:2017CEN/TR 15459-2:2017 (E) 4 Introduction The set of EPB standards, technical reports and supporting tools I

    19、n 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 drafting EPB-standards: CEN/

    20、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 of EPB-standards 2; c) the det

    21、ailed 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 standards, including specifi

    22、c 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 rules and relates to the overarc

    23、hing EPB-standard, EN ISO 52000-1:2017. 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 of a systematic, clear, comp

    24、rehensive 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). For each option, an infor

    25、mative 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 explained in some detail to readers

    26、 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 themselves, the result is likely to

    27、be confusing and cumbersome, especially if the standards are implemented or referenced in national or regional building codes. PD CEN/TR 15459-2:2017CEN/TR 15459-2:2017 (E) 5 Therefore each EPB standard is accompanied by an informative technical report, like this one, where all informative content i

    28、s collected, to ensure 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 to facilitate understanding of the set of EPB standards.

    29、 This was also one of the main recommendations from the European CENSE project 5 that laid the foundation for the preparation of the set of EPB standards. PD CEN/TR 15459-2:2017CEN/TR 15459-2:2017 (E) 6 1 Scope This technical report refers to standard EN 15459-1, module M1-14. It contains informatio

    30、n to support the correct understanding, use and national adaptation of standard EN 15459-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies

    31、. For undated references, the latest edition of the referenced document (including any amendments) applies.

    34、esented in this TR is based on the calculation of costs occurring during the life cycle of the building. The choice for the type and categories of the costs items are linked to their influence of the energy performance of the building. Restriction for the categories of costs items shall be made avai

    35、lable when this economic analysis applies to part of the building, restricted energy building systems or choice of different options. The limitation of this economic analysis may be due to the collection of data (existing building). Choices for initial based on comparison of building, or average dat

For any data different aspects are considered: the list of cost items considered (see Table 2 for example); the quantification (e.g. energy use, number and type of boilers,); the costs

    40、(energy, boilers, ) due for acquisition, maintenance, duration between replacements, and cost evolution, Operating conditions are considered as constant during the duration of the calculation period.

    41、cost items Applicable (Y/N) Initial costs Land acquisition (land acquisition, preparation, depollution,) Design (preparation, selection of teams, design,) Site Works (connections to networks, construction process and products acquisition,) Verification, commissioning (control, verification, certific

    43、ed value of building and components at the end of the calculation period, value for sale) 6.2 Time steps Time step is typically 1 year. The method could be used for shorter time step (month) with adaptation of the input data (rate evolution, lifetime,). 6.3 Assumptions Energy use, rates for prices e

    44、volution are constant over the calculation period. NOTE Formulas could be adapted to propose variation of the evolution rates.
