Sweden’s goal is to reduce the use of energy per heated unit area in dwellings by 20 percent by 2020; and by 50 percent by 2050. To fulfil these goals; Sweden’s dependency on electricity and; in particular; the large use of electricity for heating must be taken into account. The aim of this article is to study the effects of the Swedish building regulations from 1 January 2010; with regard to improving energy efficiency. The article follows the energy policy revision through policy documents and interviews.
The political goal of reducing both the annual electrical energy and the maximum instant power for heating is; on the whole; fulfilled by more efficient heat pumps. The study also shows that; in spite of the stricter building regulations for electrically heated houses; the standard of insulation required for the building to fulfil the building regulations is dependent on the heating and ventilation systems installed in the house. These changes towards more stringent requirements are also counteracted by there not being the same requirements for the existing housing stock.
