A new project to overhaul a district heating system in the Bosnian city of Banja Luka could save up to 20,000 tons of CO₂ each year and €4.5 million in heating costs.
The new project launched in Banja Luka’s City Hall today will feed into an action plan for securing major efficiency gains for the city’s district heating system, bringing both financial and climate benefits.
The city’s heating network - the second-largest in Bosnia and Herzegovina - experiences significant losses during energy transport and end-use. Boilers used in the heating system currently have an average age of 35 years and lose up to 60% of generated heat, while poor insulation means that up to 40% of heat supplied is then lost in the district’s buildings.
To tackle the problem, the City requested help from the Climate Technology Centre and Network (CTCN) with the support of the United Nations Environment Programme (UNEP).
The project will conduct city-wide mapping of the energy flow in the heating system and identify leaks using an unmanned aerial drone equipped with a thermal camera. The potential efficiency gains discovered would feed into an action plan for modernising the heating system.
District heating is one of the biggest sources of GHG emissions in Bosnia and Herzegovina. Initial calculations demonstrate that modernising the heating network could reduce fuel consumption by 27% or 4,500 tons of crude oil each year - corresponding to a reduction of 20,000 tons of CO₂ each year and €4.5m in fuel cost savings for the City.
