Degree-day method is very simple but essential index to estimate heating and cooling energy demand in buildings. It has been neglected, however, for the simplicity so it is difficult to find any DB for south Korean cities. Even meteorological department of S. Korea doesn’t report the data officially. In this study, current methods that are being used in many countries are investigated and used to calculate degree-days of 35 south Korean cities with 30 years (1981∼2010) historical data. The calculation result indicates that the error among 4 major methods are dependent on how daily or hourly temperature are treated in the calculation and how balance point temperature is defined. The errors of the methods are no larger than 6% relative to hourly degree-day method.
Abstract
Degree-day method is very simple but essential index to estimate heating and cooling energy demand in buildings.

In this study, current methods that are being used in many countries are investigated and used to calculate degree-days of 35 south Korean cities with 30 years (1981∼2010) historical data.
