Energy consumption of building for space cooling
Energy consumption of building environment systems is based on the calculation of annual expenses of thermal and electric energies on microclimate provision in premises of the building at its heating and cooling. To determine the annual energy consumption of the building it is necessary to know the thermal and geometric characteristics of its individual enclosing structures, as well as he parameters of the building's functioning, depending on the climatic conditions of the region in which it is located. The analysis of the current regulatory documents on the calculation of heat and electricity consumed by the microclimate supply systems in the premises of public buildings has been performed. This allowed to determine the potential (expected) energy consumption of the building for the cooling period. A detailed calculation is given for the example of a typical polyclinic building. The results were compared depending on the climatic conditions of the region in which the building is located. The technique proposed makes possible to estimate the need in cold energy to provide the rate (comfortable) microclimate in rooms of public buildings and to determine the energy consumption of this building.
