Landfill Gas Calculator & OtherEngineering Tools in RETScreen

Objectives

• Review basics of the

RETScreen landfill gas

calculator

• Introduce other engineering

tools available in the

RETScreen Tools worksheet

Landfill Gas

Landfills produce methane as waste decomposes

This can be used as the fuel for cooling, heating or power projects

Conclusions

RETScreen’s Engineering Tools are accessible from within the software on the Tools worksheet

Landfill Gas calculator is a companion tool which is automatically linked to the software when landfill gas is chosen as a fuel type

Other Engineering Tools provide a quick way to add detail or provide secondary information to your RETScreen project (e.g. Biogas)

You can customize and extend by building your own tools
