Energy performance of buildings. Method for calculation of system energy requirements and system efficiencies. Space emission systems (heating and cooling)What is ISO 52031 about? ISO 52031 describes the required inputs, outputs, and links(structure) of the calculation method for heating and cooling space emission systems. ISO 52031 is an international standard that provides for the efficient calculation of system energy requirements and system efficiencies in space emission systems. ISO 52031 applies to the energy performance calculation of heating systems and water based cooling space emission sub
