This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2017, and conflicting national standards shall be withdrawn at the latest by
26、November 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15459:2007. This document has been prepared
27、 under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 15459, Energy performance of buildings Economic evaluation procedure for energy systems in buildings, is composed with the following parts: Part 1: Calculation procedures, Module M1-14; Part 2: Expla
28、nation and justification of EN 15459-1, Module M1-14 CEN/TR. The revision kept the main principles of the calculation unchanged, but the structure of the document was changed. Informative content was removed to the accompanying Technical Report CEN/TR 15459-2. The values may be altered in a national
29、 annex. The main changes compared to EN 15459:2007 are: a) addition of the payback period and the addition of costs due to the end of life of the building; b) update based on the evolution of the annual costs over a specific time period; c) informative content is removed to the accompanying Technica

BS EN 154591:2017EN 15459-1:2017 (E) 5 Introduction Th
32、is European Standard is part of a series of standards aiming at international harmonization of the methodology for the assessment of the energy performance of buildings, called “set of EPB standards”. All EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency
33、. All EPB standards provide a certain flexibility with regard to the methods, the required input data and references to other EPB standards, by the introduction of a normative template in Annex A and Annex B with informative default choices. For the correct use of this standard a normative template
34、is given in Annex A to specify these choices. Informative default choices are provided in Annex B. CEN/TC 228 deals with heating systems in buildings. Subjects covered by CEN/TC 228 are: energy performance calculation for heating systems; inspection of heating systems; design of heating systems; ins
35、tallation and commissioning of heating systems. This standard gives a method for the economic calculation of the building envelope and others building related systems covered by the EPB standards. This method can be used, fully or partly, for the following applications: consider economic feasibility
36、 of energy saving options in buildings; compare different solutions of energy saving options in buildings (plant types, fuels); evaluate economic performance of an overall design of the building (for example, trade-off between energy demand and energy efficiency of heating systems); assess the effec
37、t of possible energy conservation measures on an existing heating system, by economic calculation of the cost of energy use with and without the energy conservation measure. For the correct use of this standard, Annex A will be used to specify the choices with the required input data. Information an
38、d guidance on use of the monthly and annual methods are provided in Annex B. In case the standard is used in the context of national or regional legal requirements, mandatory choices may be given at national or regional level for such specific applications, in particular for the application within t
39、he context of EU Directives transposed into national legal requirements. These choices can be made available as National Annex or as separate (e.g. legal) document. It is expected, if the default values and choices in Annex A are not followed due to national regulations, policy or traditions, that:
40、either the national standardization body will consider the possibility to add or include a National Annex in agreement with the template of Annex A; or the national or regional authorities will, in the building regulations, reference the standard and prepare data sheets containing the national or re
41、gional choices and values, in agreement with the template of Annex A. The user should refer to other European Standards or to national documents for input data and detailed calculation procedures not provided by this standard, especially dynamic economical calculation are BS EN 154591:2017EN 15459-1
42、:2017 (E) 6 not detailed in this standard. The methods to calculate the building energy demand are provided by EN 15603. NOTE Sensitivity of results increase depending on the number of parameters that are under consideration (lifetime, financial rates, ratio of price rise rates,) and as numerous are
43、 the parameters that change when comparing different solutions, as difficult will be the conclusions that rise when economic results are compared between solutions. Economical results are closely related to the project under consideration, and no general conclusion should be drawn from such results.
44、 BS EN 154591:2017EN 15459-1:2017 (E) 7 1 Scope This European Standard provides a calculation method for the economic issues of heating systems and other systems that are involved in the energy demand and consumption of the building. It applies to all types of new and existing buildings. The fundame
45、ntal principles and terminology are explained in the standard. The main items of the standard will be: the definitions and the structure of the types of costs which should be taken into account for the calculation of the economic efficiency of saving options in buildings; data needed for definition
46、of costs related to systems under consideration; the calculation method(s); expression of the result of the economic study. This European Standard is part of the method for calculation of economic performance of energy saving options in buildings (e.g. insulation, better performing generators and di
47、stribution systems, efficient lighting, renewable sources, combined heat and power). The scope of this specific part is to standardize: the required inputs; the required outputs; the calculation formulas; the type of energy systems concerned with the energy performance of the building. NOTE 1 This i
48、s the revision of EN 15459:2007. The revision has been made consistent with the EU regulation on cost-optimal. This revision includes the definition of payback for investment, and inclusion of the costs due to the deconstruction of the building. The method presenting annualized costs has been suppre
49、ssed. NOTE 2 This standard does not consider financial advantages for higher productivity, higher attractiveness for tenants due to higher indoor comfort, when relevant for comparison of different options. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 3 In CEN ISO/TR 52000-2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and a
