【 摘 要 】

The annual energy consumption of the building is greatly influenced by the internal heat intake to the premises. Under heating the incoming heat plays a positive role. During the working day, it compensates the heat losses partly or in full. As far as the cooling is concerned, the thermal emissions in the building play a negative role and the specific need for cold increases with the increase in the specific heat emissions. The aim of the study was to identify the dependence of the annual thermal consumption for heating, as well as the needs in cold for natural and artificial cooling of the building, from various factors, such as the shape of the building and its thermal protection. In annual terms, the load on natural and artificial cooling systems is less in the buildings with the lowest thermal protection and with smaller heat access into the room. It is also interesting, that the cooling load is less when the facade is more glazed, since the heat protection of the building is reducing, which only confirms the previous thesis (the heat access from the solar radiation is usually minimal, since the windows in the buildings with cooling are shaded). The smaller the building in volume is, the higher the heat the lowest energy consumption during the year is achieved with the greatest heat insulation. The ratio between the consumption of heat and cold during the year is also an important information, as the cooling of the building requires 3 to 4 times more primary fuel than heating.
