N2 - The study analyses the energy economic properties of a sample of 3800
buildings located in urban areas around Finland.On the basis of data collected
of the buildings and their energy consumption, the significance of the
various factors bearing on their energy-economic properties was examined.The
energy conservation potential in various kinds of buildings was also examined.
Oil accounts for 3/4 of the fuel used in heating the buildings under study,
including oil used in district heating systems.Over 30 % of the overall
building volume actually being heated is served by district or regional
heating.The specific consumption of heating energy in the buildings studied
fluctuates widely between types of buildings, with annual values of between 30
and 140 kWh/m³ (4-20 litres of oil/m³).Aside from the variations in function,
size, etc., between buildings, the consumption of heating energy is greatly
influenced by the maintenance and use patterns prevailing in any given
building.Interior temperature levels and the use of ventilation clearly
account for much of the dispersion in consumption values.A twofold increase in
the volume of the building brings about a lowering of specific consumption by
5-10 %.Older buildings consume less energy per unit volume than do those
erected in the 1960's and early 1970's, in which the heat consumption is
greatest.Buildings constructed since 1975 consume over 10 % less energy than
the average.It is possible within cost effective limits to reduce energy
consumption in the Finnish urban building stock by one third during the
1980's.Of the savings to be obtained, a quarter (4 TWh) can be achieved by
changes in user habits, and the remainder (13 TWh) by various repair and
renovation measures.
