The Soma-Manisa demonstration site

Adapting to change and complexity in energy efficient retrofitting projects

Soma is a town and district of Manisa Province in the Aegean region of Turkey, its electricity is produced by the SOMA power plant using local lignite and the same lignite  is used for residential heating. The demo area includes 82 buildings in total and 33 three storey, 32 two storey buildings, 8 duplex and 6 one storey residential buildings. Moreover, the demo site area includes lodging for single people, a kindergarten, a guest home and a convention centre.
