| Abstract |
Degree-days are practically used as a tool to estimate energy consumption for heating and cooling. Degree-days are calculated by summing differences of balance point temperature and outside temperature for the analyzed period. Determining balance point temperature is a key point in calculating accurate degree-days. However, ASHRAE standards are used for balance point temperature in Korea because balance point temperature considering climate conditions and building thermal performance is not proposed in Korea. This study proposes the process to generate balance point temperature for heating degree-days considering Korean climate and building conditions. Also, a new balance point temperature for three regions in Korea will be suggested in this study. Balance point temperature of Seoul is approximately 15.0℃, lower than the current standard of 18.3℃. Balance point temperature of Seoul considering climate conditions and building performance can be different from the ASHRAE suggested value (18.3℃). Results revealed the current standard for balance point temperature should be changed considering climate and building conditions in Korea. |
