This document establishes the required inputs, outputs and links (structure) of the calculation method for heating and cooling space emission systems.

This document is applicable to the energy performance calculation of heating systems and water-based cooling space emission sub-systems.

NOTE : This ISO standard is based on the CEN standard EN 15316-2. Both standards are largely identical. As long as there is no initiative to prepare a common CEN and ISO standard, ISO 52031 should be used for application outside Europe.
