Global warming is accelerating, and accordingly energy consumption is increasing over time. In Korea, the lowest temperature of Pusan in January 6 and 7, 2010 was 6.8℃ below zero, which is extreme temperature, and this abnormal phenomenon that temperature increases by 1.1-2.2℃ compared to normal years is continuously occurring. Presently weather data for energy evaluation is specified in the Korean Solar Energy Society (KSES), but there is no weather data according to extreme climate in Korea. The existing ISO-TRY is being used to conduct an energy load analysis of structures by making a platform based on ISO 15927-4 and using weather data provided by the weather center(KMA). There is a study reporting that, for building load according to changes of weather elements in the standard weather data, when dry-bulb temperature increased by 2.6 degrees, cooling load increased by 39.53%, and when solar radiation increased by 48%, it increased by 31.65%, and relative humidity and wind speed showed a very low level of changes, 0.06-3.53%. Thus, it is judged that changes of dry-bulb temperature and solar radiation would have the largest influence on establishing extreme climate data for analyzing building load. This study tried to analyze various measures by setting the weighted values of dry-bulb temperature and solar radiation high and those of wind speed and relative humidity low. It set three parameters for dry-bulb temperature, daily maximum, daily minimum, and daily average, and set one parameter, daily average, for solar radiation, relative humidity, and wind speed. This method does not largely deviate from the methodology of Design Summer Years, extreme climate data using only one parameter, daily average dry-bulb temperature, which was typically established and suggested by ISO 15927-4. The purpose of this study was, focusing on data calculated through the newly suggested method and dry-bulb temperature calculated by ISO-TRY, to compare limit values of 99.6, 99.0, 98, 2.0, 1.0%, and 0.4% with the average value of the last 30 years to suggest an extreme climate data methodology. |
