Energy consumption is particularly relevant to the three-sector concept, including the industrial, service, and agricultural sectors. Consequently, energy consumption in the building and construction sectors has become one of the most pressing global concerns. As the world population grows, the energy demand of buildings, particularly energy consumption in the public buildings has been increasing rapidly. Various methods have been applied to manage energy consumption in public buildings. The correct application of these methods has been shown to facilitate the rapid detection of energy consumption in public buildings and the acquisition of more detailed consumption data. As demonstrated by this study, the BIN Method, which is based on meteorological data, has been used to determine energy consumption in buildings with accuracy
comparable to accual values. In this study, the energy consumption of a building owned by the Istanbul/Beykoz Municipality was determined using the BIN method. To apply the BIN method, Dry Air Thermometer (DAT) temperature data, expressed as Typical Meteorological Year (TMY) values, were used; these values were derived from 25 years of meteorological data at the Istanbul Göztepe station. The required energy consumption for the heating and cooling of the municipal administrative building has been calculated using the BIN method. A comparison was made between the values obtained using the BIN method and the actual invoice values. The results of the present study indicate that energy consumption in public buildings can be reliably estimated using the BIN method and that annual energy demand can be determined efficiently.
