Energy performance of buildings - Economic evaluation procedure for energy systems in buildings - Part 1: Calculation procedures, Module M1-14
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. See also Clause 2 and Tables A.1 and B.1.

5 Description of the method 5.1 General This standard presents the calculation method that is used for aggregation of the past, present and future costs over a period of calculation. When this period includes the demolition of the building the disposal costs for deconstruction/demolition are also included. This calculation method is also named ‘global cost’. The time step of the output is yearly based, but can be adapted to a monthly period. 5.2 Output of the method The output of the calculation method is the value of the global cost.

Hours RAThu % Different values could be used depending on purpose and skills Service RATser %
Energy RATen_1 % Different values could be used depending on the type of energy and energy provider
Costs could be annual (energy, maintenance, taxes, insurance) or periodic (replacement) depending on the lifespan of the products or the scheduled replacement for products or systems. 5.3.4 Final costs 5.3.4.1 Calculation of the residual (final) value The final value VALfin(j) of a component is determined by straight-line depreciation of the initial investment until the end of the calculation period and referred to the beginning of the calculation period (Formula (3)). If the calculation period TC exceeds the lifespan Tn(j) of the considered component (j), the last replacement cost is considered for the straight-line depreciation: SIST EN 15459-1:2018

Total cost during the calculation period considered is the sum of: — initial investment A0 (value of the initial investment rises with time due to inflation rate); — cost for the first replacement ()=+10pr1'*LSAARAT SIST EN 15459-1:2018
The global cost for solution x is expressed as dependant of the time period of calculation TC. 6.2 Calculation time steps The calculation method described in Clause 7 is suitable for the following calculation time steps: — yearly; — monthly. If an input data are available with a shorter time step than the output or the calculation time step, the value or the cost is adapted in proportion with the periodic time of the specific input and the time step used for the calculation. Conventionally the values of the input data occurring during the time step of calculation are reported to the beginning of the time step of calculation without any adjustment. SIST EN 15459-1:2018
6.3.3 Specific input data for products and services For each cost item considered (product, category of products, service or system) Tables 7 and 8 describe the type of information needed. The costs occurring during the operation time of the building can be expressed either with their respective quantity or values (Table 7) or expressed as a percentage of the investment costs (Table 8).

Inflation rate: — estimated from available economical (institute) data; — for information only as all rates are real rates reduced form the inflation rate). Discount rate: usually stated at the national level. Rate of development of human operation costs: — depends on the cost development due to staff in operation (usually the rate of development of human operation costs is higher than the inflation rate).
