Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - Part 4-8: Space heating generation systems, air heating and overhead radiant heating systems, including stoves (local), Module M3-8-8

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 standardize the:
-   required inputs;
-   calculation method;
-   resulting outputs,
for space heating generation by:
-   air heating systems, including control;
-   overhead radiant heating systems for non-domestic use, including control; and
-   stoves and local heaters for residential use.
This standard does not apply to heating systems that utilize water as a heat transfer medium.
Other heat generation systems such as boilers, heat pumps and others are covered in other sub modules of M3-8.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000-1.
NOTE 1   In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2   The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
