3.4 Media properties
The CO
2
emissions associated with energy consumption can be displayed for all
CO
2
-emitting media. Consumption values can be converted into the required units
[kg CO
2
] by use of emission factors. Newly defined or modified emission factors
are assigned a time stamp which is automatically taken into account in the report-
ing function.
For heating media measured in volumetric units, individual calorific values can be
assigned to each node. Newly defined or modified calorific values are allocated a
time stamp which is automatically taken into account in the reporting function. This
facility can be used, for example, to display heat consumption in kWh based on a
gas volume measurement in m
3
.
