New regional energy statistics for single- or two-dwelling buildings
The energy use of single- or two-dwelling buildings (referred to below as houses) varies from county to county. The highest energy use per house is found among those situated in counties in the northern part of Sweden, while the lowest use is registered in houses located in Blekinge. Electric heating is the most common method of heating. This can be seen from the Swedish Energy Agency's energy statistics for houses, which contain statistics on all the counties and municipalities in Sweden.
"The amount of energy needed to heat a house depends to a large extent on its energy performance with respect, for example, to insulation and type of windows. Heating a house that was built before 1940 requires considerably more energy than for a house built in the 21st Century," says Lars Nilsson, Analyst at the Swedish Energy Agency.
The average house had an energy use of 23,200 kWh in 2010
The lowest energy use for space heating and hot water was registered in houses situated in the county of Blekinge, with 21,000 kWh per house. The highest energy use per house was found to be in those situated in counties in the north of Sweden: Västerbotten, Norrbotten, Gävleborg and Västernorrland. The level of energy use was found to be highest in the county of Västerbotten, with an average of 26 700 kWh per house.
Throughout Sweden, an average of 158 kWh was used per square metre last year. Here, the difference between the different counties is clear: in a house in Gävleborg, an average of 185 kWh was used per square metre in 2010, whereas the average use for a house in Skåne was 147 kWh per square metre.
The average energy use per house and square metre is higher in the counties of Norrland, which is only natural since the winters are generally longer and colder there. The counties of Skåne and Blekinge have the lowest energy use per square metre.
Electric heating is the most common method of heating houses
Electric heating, either direct acting or waterborne, is the most common heating method in Swedish houses. A total of 518,000 single- or two-dwelling buildings were heated exclusively by electricity in 2010, which is 27 per cent of Sweden's 1,896,000 houses in this category. The second most common heating method is a combination of biofuel and electric heating, with which 382 000 houses, or 20 per cent, were heated during 2010.
District heating has become increasingly common. Today, 230,000 single- or two-dwelling buildings, or 12 per cent of the housing stock, were heated solely by district heating.
The number of heat pumps has continued to increase. In 46 per cent of all houses, some form of heat pump was used in 2010.
Oil accounts for the heating of 1 per cent of single- and two-dwelling buildings.
About the statistics
The year's report applies to the year 2010 and is based on a questionnaire that was distributed to 73,000 single- and two-dwelling buildings, to be compared with 7,000 similar houses the year before. An extended survey of this type is made at regular intervals, the last time being in 2003. The response frequency for the survey was 64 per cent.
The purpose of energy statistics for single- and two-dwelling buildings is to provide information on, among other aspects, method of heating, energy use and area in hose with permanent residents. The results are based on a questionnaire survey conducted by Statisticon on behalf of the Swedish Energy Agency. The survey has been conducted annually since 1977.
