    A number of prospective district heating solutions were investigated for the first time in the context of application to buildings needing 75 % less energy than standard today. Conducted analysis suggests that district heating with traditional room radiators and current billing tariff structure may not be cost effective due to high investment costs. However, other options exist. The most cost-effective district heating solution was based on ventilation integrated heating. The solution included domestic hot water system equipped with a storage tank connected to district heating network through a heat exchanger. Present values (of energy and investments) of all 9 investigated solutions projected over 30 years span remained within the apparently narrow range band of 0.23-0.33 /m2 per month. This indicates that in addition to costs also other features should be considered when selecting the building's energy system. These could be e.g. achievability of high indoor comfort level, functionality, outlook of heating terminals.
