In January 2016 a new pricing model for district heating will be introduced by Vattenfall in Uppsala. The public housing corporation Uppsalahem is one of Vattenfall’s biggest customers and by using one of their residential areas, August Södermans road, a case study was made in order to examine how the new pricing model might affect Uppsalahem. According to Vattenfall one reason for the switch is to give incentive for their customers to use more energy efficient solutions. This was studied by modelling two energy efficient solutions for the houses at August Södermans road. By changing the ventilation systems to FTX and invest in improved windows, Uppsalahem would have been able to save 940 MWh for the year 2013 at August Södermans road. A comparison between the current and the new pricing model showed that Uppsalahem would save 9 000 SEK with the new pricing model applied on August Södermans road at its current condition. If the two energy efficient solutions were taken into consideration the new pricing model would result in a decrease with 21 000 SEK for the year 2013.
