25. Energy Scenario Modelling
Energy-Technology-Environment Model for MUSIC
(ETEMM)
A tool to explore urban development scenarios;
Based on a techno-econometric model of the city’s
infrastructure and energy demand;
Calculates long term CO2 emission trends;
Alternative scenarios can be developed using the potentials
calculated by the Modules;

29. What’s next ?
The MUSIC Consortium will
complete the spatial information on renewables potentials in
the cities and integration into the energy planning,
enable the 5 partner cities to make full use of the possibilities
of iGUESS via constant knowledge transfers and trainings,
enable the Cities to generate maps in a fully automated way,
look for possibilities to transport the tools and methods to
other European Cities.

33. Questions for discussion
Where do you see links to your daily work and/or life?
What are the needs of your municipality to set up a more
targeted and efficient energy policy?
Do you have the necessary information to build future energy
scenarios for your city?
Are GIS tools usually used to plan energy related topics in your
field?
Would you like to collaborate on an implementation of such
Modules/approaches for Luxembourg?
How could citizens and local actors be involved?
What kind of information should tools, such as iGUESS,
contribute to make your work easier?
Do you see business opportunities with such approaches?
Do you see potential to get inspired by such tools to start new
initiatives or enhance existing one?
