National foreword This document (EN 16627:2015) has been prepared by Technical Committee CEN/TC 350 “Sust

5、ainability of construction works” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the DIN-Normenausschuss Bauwesen (DIN Standards Committee Building and Civil Engineering), Working Committee NA 005-01-31 AA Nachhaltiges Bauen (SpA zu ISO/TC 59/SC 17 und CEN/

6、TC 350). Remarks regarding the German translation and terminology The term “default value” is to be understood as a recommended substitute value. Other German terms for the English term “discount rate” (other than “Diskontierungszinssatz”) are “Diskontsatz” and “Abzinsungssatz” (see e.g. Subclause 1

7、0.2). As regards the German term “Kosten” (“costs”): These are to be understood to be expenses and/or outgoing payments. As regards the German term “Ertrge” (“incomes”): These are to be understood to be revenues and/or incoming payments. As regards the term “Abfall” (“waste”) (in Subclause 3.70): In

8、 Germany, waste in connection with building measures is normally considered as recycling material. As regards the term “Nachhaltigkeit” (“sustainability”) (in Subclause 3.62): In Germany, the meaning and aims of the concepts “sustainability” and “sustainable development” are set down in Germanys Nat

9、ional Sustainability Strategy1)(for general considerations) and the “Guideline Sustainable Building”*), in its current version (for questions relating to planning and building). In German, costing that only takes costs (outputs) into consideration is called a “Lebenszykluskostenrechnung im engeren S

10、inne”, which takes account of “negative costs”. This is equivalent to the English term “life cycle costing (LCC)”. The term “Lebenszykluskosten im weiteren Sinne” refers to costing that also takes revenues (inputs) into account. This is equivalent to the English term “whole life costing (WLC)”. The

11、costing result can be evaluated on the basis of the “Lebenszykluskosten im weiteren Sinne” and used to assess efficiency. It is recommended that the current edition of KRUSCHWITZ*)be used for a precise calculation of the NPV and NPC (see 11.3). The English term “end of life” describes the end of the

12、 life cycle of the construction works. It covers a number of different scenarios. In German this is understood as including deconstruction and disposal. Disposal can include the recycling of construction components and materials. Altogether, this life cycle phase is referred to in German as the “Ent

13、sorgungsphase” (disposal phase). 1 ) Die nationale Nachhaltigkeitsstrategie, German Federal Government, 2002.

15、l of the intrinsic value of the investment. Here the relationship between the costs and the created value is evaluated. The three categories of income approach valuation methods (direct capitalization, discounted cash flow and gross income multiplier) mentioned in this standard are used internationa

16、lly. In Germany there are similar valuation rules and methods which nevertheless deviate in detail. National valuation rules are to be taken from the Immobilienwertermittlungsverordnung (ImmoWertV) (German Real Estate Valuation Ordinance). Other valuation methods widely used in Germany are the repla

DIN EN 16627:2015-09 EN 16627:2015 (E) 5 Introduction The purpose of this European Standard is to provide calculation rules for the asse

42、ssment of the economic performance of new and existing buildings as one part of an assessment of the sustainability of the building. It complements the European Standard EN 15643-4. In EN 15643-4 the following economic assessment indicators are described: This standard describes the methods and the

43、rules for calculating the cash flows over the life cycle of buildings, with an emphasis on the field of life cycle costing. Principles developed in ISO 15686-5 are included, but have been adapted for sustainability assessment in the European context. This standard describes two approaches to the cal

44、culation of economic performance: a) Life Cycle Costing: Economic performance expressed in cost terms over the life cycle, taking account of negative costs related to energy exports and from re-use and recycling of parts of the building during its life cycle and at the end of life. Calculation of th

45、is indicator is mandatory for compliance with the standard. b) Life cycle economic balance: Life Cycle Costing (see above) and in addition incomes over the life cycle and at the end of life. Calculation of this additional indicator is optional for compliance with the standard. NOTE 1 Annex C describ

46、es a further optional approach, value stability. This European Standard is part of a suite of European Standards, Technical Specifications and Technical Reports for the assessment of the economic performance of buildings that together support quantification of the contribution of the assessed buildi

47、ng to sustainable construction and sustainable development. The economic performance of a building is only one aspect of its sustainability. The environmental and social performance of the building are also aspects of sustainability that are assessed as part of a sustainability assessment. These are

48、 described in the framework standards (EN 15643-1, EN 15643-2, and EN 15643-3, EN 15643-4). NOTE 2 The economic assessment is undertaken at the building level. However, it requires technical and cost information about individual products and components within the building and its services and systems, including service life data, type and frequency of inspection, replacement, cleaning, maintenance and repair, and deconstruction and disposal. This information is used as input quantities for the ca
