Overview - EN 15459-1:2017 (Module M1-14)
EN 15459-1:2017, published by CEN, defines a standardized economic evaluation procedure for energy systems in buildings (Module M1-14). The standard applies to all new and existing buildings and provides calculation procedures for assessing the economic performance of heating and other systems that affect building energy demand and consumption. This part standardizes required inputs, outputs and calculation formulas and is aligned with the EU cost-optimal framework. It supersedes EN 15459:2007 and introduces payback definitions and end-of-life / deconstruction costs (the annualized-cost method was removed).
Key topics and technical requirements
- Scope & terminology: Fundamental principles, definitions and the modular position within the EPB (Energy Performance of Buildings) standards.
- Cost structure: Clear breakdown of initial costs, annual costs, and final costs to be included in economic evaluations.
- Economic parameters: Use of discount rate / present value factors, and other financial inputs required for present-value calculations.
- Calculation method: Step-by-step procedure covering financial/project data, component and system costs (investment, replacement), energy costs, global cost calculation, and payback period computation.
- Inputs and outputs: Normative templates in Annex A (required inputs) and informative default choices in Annex B.
- Quality control & reporting: Requirements for calculation reporting and for comparing different retrofit or design options.
- Limitations: Non-financial benefits such as increased productivity or tenant attractiveness from improved comfort are explicitly excluded.
Practical applications and users
EN 15459-1:2017 is intended for professionals and stakeholders involved in building energy and economic assessments:
- Energy consultants and assessors performing cost-optimal or life-cycle economic studies
- Building services engineers evaluating heating, distribution and renewable integration options
- Architects and designers comparing envelope vs. system trade-offs
- Policy makers and regulators implementing national/regional annexes to meet EU directives
- Facility managers and developers planning investments, replacements or decommissioning
Use cases include economic feasibility of insulation, efficient generators, lighting upgrades, renewable systems, CHP integration, and retrofit decision-making.

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).

The article discusses EN 15459-1:2017, a European standard that provides a method for calculating the economic evaluation of energy systems in buildings. The standard applies to both new and existing buildings and covers heating systems and other systems involved in the building's energy demand and consumption. It explains the fundamental principles and terminology related to economic efficiency and defines the costs that should be considered in the calculation. The standard also specifies the required inputs, outputs, calculation formulas, and types of energy systems covered. The revision of the standard aligns it with EU regulations and includes definitions of payback for investment and costs related to building deconstruction. However, it does not consider financial advantages related to higher productivity and indoor comfort. Table 1 in the article shows the position of this standard within the set of EPB (Energy Performance of Buildings) standards.
