GEMIS assesses the final utilization based on
the used resources
Calculation of life cycles incl. construction and
disposal (if wanted)
Including transport, process energy, support
energy, materials etc.
Project „Standard“ contains checked figures
Own processes to add or look up known
processes
Problem: non-linear relations, loops

Emission calculation
 Separate lecture
Climate change gases
 CO2 equivalent
 CO2,
 SO2
CH4, N2O, refrigerants
equivalent
 Air
emissions
 Or individual figures
 TOPP
equivalent
 Ozone
precursor substances
CU

Products
 Energy resources
 Complete
data
 Needed for exact emission calculation
 Materials
 Costs
and environmental impact
 Resources
 Renewable
 Emissions

Processes
 Example combustion
 Connection
to process energy delivery
 Definition of efficiency
 Main and additional products/by-products
 Costs
 White cells can be edited, grey cells are
calculated by GEMIS
 Calculation of emissions
 Evaluation of emission reduction measures
 Example
Energy conversion
