Distribution of savings for Zagreb
16% of apartments with higher energy bills
For Zagreb, Osijek and Sisak(80% of total delivered heating energy):
Positive NPV only for buildings that consume >170 kWh/m2 (minimal set of equipment or >220 kWh/m2 (full set of equipment)

District heating substation
Project: Standardized district heating substations
Goal: Modernization and improvement in flexibility
Planned improvements:
• Possibility of integration with renewable energy sources at the building location
• Possibility to chose optimal heating regime using secondary side temperature control
• Separate measurements for heating and domestic hot water
• Modern control that enables remote metering and optimization of relevant heating
parameters
• Simplification and shortening of the design process
