ANALYSIS OF BIN WEATHER DATA FROM DIFFERENT PERIODS FOR THE CITY OF NIŠ

Abstract

This paper presents a comparison of bin weather data for the City of Niš, over two time periods (2002-2009 and 2014-2021). The data are essential for estimating energy consumption for heating and cooling of buildings. Using weather records for the period spanning two decades (2002-2021), bin weather data ranging from the minimum to the maximum values of the outdoor dry bulb temperature recorded in this period were calculated with 2oC increments in six equal daily shifts. Hourly measurements of dry bulb temperature, relative humidity and atmospheric pressure were used in the performed calculation, and the results are presented in tabular form. These results are suitable for building energy analysis using the basic or modified bin method, especially for applications with air-to-water and air-to-air heat pump systems. In addition, one can notice that there is a tendency of shortening the heating periods and prolonging the cooling periods because of the increased recorded air temperatures.
