Abstract

This study presents an independent implementation of the monthly energy demand calculation procedure defined in ISO 52016-1 and a quantitative verification of its reliability. A calculation module for heating and cooling energy demand was developed based on the energy balance framework of the ISO 52016-1 monthly method. The developed module was validated using BESTEST Case 940 through a comparison with the monthly calculation results of the EPB Center Tool, which follows the same standard framework. The verification included both a stepwise comparison of the calculation procedure and a monthly comparison of heating and cooling energy demand results. The results demonstrate very high agreement between the two implementations, with coefficients of determination (R²) exceeding 0.999 for both heating and cooling and very low statistical error indicators. These findings confirm that the developed ISO 52016-1 monthly module faithfully reproduces the calculation structure intended by the standard and provides a reliable basis for standard-based energy demand assessment tools.
