Sustainable Passive Plus houses with Bio District heating, learnings from a case study in Tarm, Denmark.
By Søren Dietz
In Denmark 2/3 of building heat is District heating. The political aim is to reduce CO2emissions by 70% in 2030 with 1990 as reference. Buildings make up for 40% of the CO2 emissions – so reducing green house gas from building play a major role.
Greenhouse gas reduction may come from both saving energy and transforming the energy sector to non fossil. Biomass resources are not local grown. 2/3 of wood Biomass for District Heating is imported from Russia and the Baltic countries.
How can Denmark achieve climate goals, in a sustainable way, with Bio District heating with less Biomass – is more building insulation the answer?
