Demo Sites
The selected Demonstration District is part of the CIT Bishopstown campus district in Cork, Ireland. The district is a third level institute, hosting about 800 full-time staff, 650 part-time staff, 7800 full time students and 3200 part time students. As such, it is primarily used for education (main building block) and research (CREATE). This makes the district research friendly and ready, facilitating a living lab environment in which research experiments and demonstrations can be carried out across the whole operating envelope of the DHC system, which would typically not be possible in a commercial DHC system. Occupancy is mostly during office hours and varies with the academic year. It dips in Dec-Jan (60, 20% occupancy), April (60% occupancy), and July-Sept (20, 20, 30% occupancy). The research strategy for CIT is to create a campus wide research infra-structure for energy research. 

In order to assess whether the research outputs of E2District are replicable beyond the CIT campus district, Veolia has identified possible district heating network sites from their portfolio that we will use to assess transferability of results and approaches. Among the most interesting sites for the project, Veolia has identified the site of Varna in Bulgaria. The technical configuration of this district heating network associated with the geographic location were key factors in this selection.

A Few Varna DHN key numbers:
  • About 34 kilometers long
  • Heat supply to 12 000 equivalent apartments
  • Less than 100GWh annual heat consumption
