scope:

NEN-ISO 17742 provides a general approach for energy efficiency and energy savings calculations with indicator-based and measure-based methods for the geographical entities countries, regions, and cities. This International Standard considers all end-use sectors, such as households, industry, tertiary (services, etc.), agriculture, and transport. It does not incorporate calculation of energy efficiency and energy savings in energy supply sectors, such as power plants, refineries, and coal mines. Energy consumption does not include feedstock energy, such as oil products for the production of plastics. This International Standard is not intended to be used for calculating energy savings of individual households, organizations, companies, or other end users. Energy from renewable energy sources "behind-the-meter" (e.g. from solar water heating panels) decreases the amount of supplied energy and can be part of the calculated energy savings. Users of this International Standard should be aware that this energy from renewable energy sources behind-themeter can also be claimed as part of the total energy from renewable sources.
