CALCULATION OF LOCAL LOADS
This task involves calculation of loads from different subprocesses (heat, humidity, contaminants). Loads are usually time dependent, which has to be taken into account. See Fig. 3.8.

Emission Data or Calculation Mode! for Emission Source
Explanations of Fig. 3.8
Step I : Emission Data/Calculation Model
Obtain data from Source Description.
Step 2: Changes to the Calculation Model
• Derive modifications on the case
• Make additional modifications, if returned from Local Protection
Step 3: Calculation of Loads to Environment
Calculate emissions from the source to the environment.
The tools for this task include design tools for calculation (models) and measured data of emissions in different processes, which are defined in Source Description.
