Soma is located in the Manisa province, western Turkey and has a population of about 90 000 people. The town has grown around the lignite mining industry and the lignite-fired thermal power plant. The pilot demonstrator district consists of a total gross area of 64 971 m2, of which 41 158 m2 is a conditioned area. The total population in the demo site is around 2000 people.

In general, buildings in the area are heated by coal-based heating systems, where old-fashioned stoves heat around 70 % of dwellings and only 30 % of buildings are heated by central heating boilers with their own radiator systems. As a result, the air quality in the region has suffered greatly. To tackle this, the local government has placed district heating implementation at the top of their agenda.

Taking into account these conditions, two different retrofitting strategies were implemented:

  • application of passive design strategies on the building envelope adding defined building elements such as insulation;
  • integration of active design strategies such as building-integrated photovoltaic and solar thermal collectors as a renewable technology, innovative integration of monitoring systems for providing best indoor comfort conditions and energy savings.

The overall gross floor area of 41 158 m² will be refurbished in Soma within the CITyFiED project. The annual final energy saving estimate is 4320 MWh. The total CO2 emission savings estimate amounts to 1083 tonnes of CO2 per year.

The tender process for publicly owned buildings is proving to be time-consuming and intricate.

The local teams are on a tight schedule to complete the renovations on all the intended dwellings within the project’s duration.

A number of political and financial changes and events in Soma delayed the start of the works. One of the major risks for the project is the government’s decision to privatise SOMA Electricity Generation & Trading Joint Stock Company (SEAŞ). This has influenced decision-making, prioritisation, budgeting and resource allocation for the company, which is at the centre of the interventions at the demo site and the related investments. In addition, these changes have led to new requirements for the buildings in the Soma demonstration site in terms of seismic testing.

The risk is gradually being overcome. However, there are some concerns that SEAŞ will become a significantly smaller enterprise in the process, affecting current resource arrangements. Given the social aspects and attractiveness of the project, the local team is assessing the progress of the situation and acting accordingly.
