Savon Voima Oyj_logo

Savon Voima Oyj's sustainability challenge: 
Smart and climate-friendly district heating

Challenge Description:

What should smart and environmentally-friendly district heating look like in the future?
In what creative ways could the data collected by district heating companies be utilized to achieve an intelligent and climate-smart district heating system?


-In Finland, heating buildings accounts for approximately a quarter of all energy consumption, and at the personal level, housing and related energy use contribute to about 25% of the carbon footprint of the Finnish population.

-District heating emissions have decreased by half over the past ten years and are expected to be reduced to one-third of the current levels over the next 10 years. However, there are still significant development needs in district heating. Unlike the past, where the supply water temperature of district heating was determined by outdoor temperatures, modern automation now takes into account temperature fluctuations, weather data, room temperature, building mass, and optimizes the supply water temperature based on these factors.
