Optimized heat for areas with low-energy buildings

The OptiHeat-LEB project investigates how the choice of heating technology in areas with low-energy buildings affects costs and the design of energy systems in the long term at local and national level. The project also investigates how much impact different heating techniques have on carbon dioxide emissions in an international perspective.

The project is run by IVL Swedish Environmental Institute in collaboration with energy companies, housing companies and the construction industry line association. The goal is to develop knowledge as a basis for planning new areas with low-energy buildings so that the most climate-smart and cost-effective heating solutions are used. The work includes the energy system as a whole and the analyzes include greenhouse gas emissions at both local and international level.

The four heat supply options being studied are:

  • individual heat sources for each property
  • small-scale low-temperature district heating network (local heating network)
  • connection of return line in an existing, nearby, larger district heating system
  • a combination of district heating and individual heat sources with the possibility of also supplying heat from the building to the district heating network (prosumer).

The knowledge base will, for example, be able to be used by urban planners, entrepreneurs and energy companies, but due to the long-time horizon will also be relevant for participants who design frameworks for energy policies and building regulations.
