scope:

This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies.

The scope of this specific Part is to standardise the:

- required inputs;

- calculation method;

- resulting outputs

for space heating generation by:

a) air heating systems, including control, and

b) overhead radiant heating systems for non-domestic use , including control.

This European Standard does not apply to air heating systems that utilise water as a heat transfer medium.
