Reduced energy use for multi-dwelling buildings and non-residential premises, 2011
There was a decrease in the use of energy for space heating and hot water in multi-dwelling buildings and non-residential premises during 2011. A multi-dwelling building used, on average, 140 kWh per square metre for heating and hot water, which corresponds to a decrease of 18 kWh compared with the year before.
A total of 24 TWh were used for heating and hot water in multi-dwelling buildings in 2011, which is a reduction of 5 TWh compared with 2010. In the case of non-residential premises, the energy use decreased from 19 TWh to 18 TWh during the same period. This is apparent from new statistics issued by the Swedish Energy Agency.
"2011 was a much warmer year than 2010, so part of the reason for the lower figures is quite simply connected with the temperature. Warmer weather means a decrease in heating demand and thus a decrease in energy use," says Lars Nilsson, Analyst at the Swedish Energy Agency.
An average of 10,200 kWh of energy is used for heating and hot water purposes in an apartment in the year 2011. Energy usage was 140 kWh per square metre in multi-dwelling buildings and 130 kWh per square metre in non-residential premises. This can be compared with the year 2010, when a total of 11,500 kWh were used per apartment, 158 kWh per square metre in multi-dwelling buildings and 146 kWh per square metre in non-residential premises.
District heating predominant method of heating
District heating is by far the most common method of space heating in both non-residential buildings and multi-dwelling buildings. So in multi-dwelling buildings, 86 per cent of the heated area was heated solely by district heating. The corresponding figure for non-residential premises was 72 per cent. The use of oil continues to decrease for both multi-dwelling buildings and non-residential premises. During 2011, oil accounted for 3 per cent of the energy used for heating and hot water in non-residential premises and 1 per cent in multi-dwelling buildings.
About the statistics
The purpose of the statistics is to provide information on the method of heating used, on the energy used and on how the areas are used in the present stock of multi-dwelling buildings and non-residential premises. The statistics serve as a basis for, among other aspects, energy balances, national accounts and reporting to Eurostat. Both surveys have been conducted since 1977.
The statistics have been drawn up by Statisticon on behalf of the Swedish Energy Agency. More details on the statistics can be found in the publications Energy Statistics for Multi-dwelling Buildings and Energy Statistics for Non-residential Premises.
The extent of the selection of multi-dwelling buildings studied in the survey is approximately 7,000. The response frequency for the year's survey was 65 per cent. The population is restricted to apartment block units, houses and non-residential premises. The buildings shall have been completed by 2010 and shall contain at least 3 residential units. Non-residential properties and agricultural properties are not included in the population.
The extent of the selection of non-residential premises studied in the survey is approximately 10,000. The response frequency for the year's survey was 67 per cent. The population studied includes hotels and restaurants, building blocks containing primarily non-residential premises, care buildings, swimming, sports and athletics facilities, and schools. In addition, the buildings shall have been completed by 2010. Industrial and agricultural properties are not included in the population.
