Abstract
District heating is widely used in heating buildings in
Finland. Due to new European legislation, increasing
adaption of renewables, and new stakeholders in the
heating business, Finnish district heating needs to
evolve. This paper analyzes energy and emissions impacts
of different heating energy scenarios in a typical
Finnish district heated area. A period of 20 years
(2015-2035) was studied assuming the future development
of the building stock.
The conservative, extensive and extreme scenarios assumed
different amounts of solar energy and ground source heat
pumps to be implemented as decentralized systems. In
addition, two heat prosumer scenarios were analyzed,
namely an industrial waste heat scenario and a modest
solar heat prosumer scenario.
Despite the increase of the buildings' total floor area
by about a third, the combined heating and domestic hot
water consumption per floor area was estimated to
decrease by about 36%. The extreme scenario with ground
source heat pumps and a solar thermal system decreased
the annual centralized heat production by 34% and the
industrial waste heat scenario by 32%. The waste heat
scenario decreased the emissions the most.
