For example classify sound
attenuation for distribution
elements at G63.
G61 Energy generation/storage/ Classify the complete elements to
conversion which these parts belong with
reference to Section G5, e.g.:
G61:G50 Energy generation/
storage/conversion for water supply
G61:G52 Energy generation/
storage/conversion for HVAC
G61:G53 Energy generation/
storage/conversion for electric power
1 Heat output
1 Heat generation
i.e. boilers (including fuel
storage), solar collectors.
2 Heat conversion
i.e. calorifiers, heat
exchangers,
2 Electricity output
1 Electricity generation
i.e generators, turbines,
photovoltaic cells.
2 Electricity conversion
i.e. transformers, convertors.
3 Cooling output
4 Combined heat/power/cooling
G62 Non-energy treatment/ Classify the complete elements to
storage which these parts belong with
reference to Section G5.
G63 Distribution Classify the complete elements to
which these parts belong with
reference to Section G5, e.g.:
