ISO

ISO/TC 163

International Standard

Scope

This standard will provide a calculation method for the economic issues related to the building envelope and technical building systems that are influencing the energy demand and energy consumption of the building. This standard applies to all types of buildings.
The fundamental principles and terminology will be explained in the standard.
The main items of the standard are:
- definitions and structure of the types of costs, which shall be considered for the calculation of the economic efficiency of saving options in buildings,
- data needed for the definition of costs related to systems under consideration,
- expression of the result of the economic calculation,
- informative annexes indicating default values of e.g., lifetime, costs for repair, costs for maintenance, in order to introduce default values for calculations.

This standard is applicable to the calculation of the economic performance of energy saving and efficiency options in buildings (e.g., insulation, better performing generators and distribution systems, efficient lighting, renewable sources, combined heat and power).
