The influence of the climatic features of the construction area on the level of energy-efficient thermal protection of of the office buildings

Abstract

The choice of the level of the building thermal protection should be based on economic indicators of these buildings, taking into account the cost of maintaining a given room thermal microclimate. However, an economic calculation can only be performed after evaluating the impact of the thermal protection level on the building energy performance. The specific energy consumption of a building is affected by the size of the building, since in the buildings of different lengths and number of storeys, the ratio of ordinary rooms on the intermediate and the upper floors is different, as is the number of ordinary and corner rooms. The purpose of the article is to identify the energy consumption for heating, free and machine cooling of the buildings of various sizes and number of storeys in the areas which differ by the heating period duration and the solar radiation intensity, i.e. in Moscow and in Astrakhan. Three options of the building thermal protection have been considered herewith, differing from each other in the resistance to heat transfer of the outer wall and the coating. The area of the windows made 55% of the facade area. The calculation has been performed for several values of the outdoor air temperature during the year in each city.
