Influence of heat measurement method on consumed amount of heat in dwelling houses

Abstract

As the oil price and related fuel in last decades strictly and constantly rises, the different measures are applied to decrease energy consumption in a buildings. The development of building constructions of a new type and application of better insulation, proper orientation of a building, replacement of natural ventilation system by forced recuperated ventilation system and other means can be described as the main tool to decrease energy consumption. But if we will overheat well insulated building and heat surplus will be thrown away through the open windows, all measures under application will be lost in vain. A lot of studies of the efficient energy consumption recommend organisational measures also. Most popular example for efficient electricity usage is very simple - to turn off the light leaving the premises and only later change bulbs into more efficient. Taking such measures as very important, this article analyses four types of heat measurement methods in a building: then building has only one coomn heat meter for all entire building, then building has installed heat cost allocator units on every heating device, then every flat in a building has its own heat meter and then every flat in a building is heated by individual gas boiler. All these heat measurement methods influences behaviour of a heat consumer in a different way. Study shows that the total energy consumption in a buildings of the same construction type but with the different heat measurement method differ in a large scale, so due to reconstruction of a heating system and changing the heat measurement method can be achieved an obvious energy consumption and carbon dioxide reduction result.
