BS EN 15459-1:2017 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.
