本欧洲标准为参与建筑物能源需求和消费的供暖系统和其他系统的经济问题提供了一种计算方法。它适用于所有类型的新建和现有建筑。 标准中阐述了基本原则和术语。 标准的主要内容如下: - 计算建筑物储蓄期权经济效益时应考虑的成本类型的定义和结构; - 与正在考虑的系统有关的费用的定义所需的数据; - 计算方法; - 表达经济学研究的结果。 该欧洲标准是计算建筑节能选择（例如隔热，更好的发电机和配电系统，高效照明，可再生能源，热电联产）的经济性能计算方法的一部分。 这个具体部分的范围是规范: - 所需输入; - 所需输出; - 计算公式; - 涉及建筑物能源性能的能源系统类型。 注1:这是EN 15459:2007的修订版。修订符合欧盟关于成本优化的规定。本修订包括

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 fundamental 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 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 distribution 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 is 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 suppressed. 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 accompanying technical reports that are published or in preparation. NOTE 4 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
