To establish the design criteria for seasonal heating load calculation in greenhouses, standard weather data are required. However, they being provided only at seven regions Korea. So, instead of using data, order to find method build calculation, degreehour and degree-day were analyzed compared by methods fundamental equation, Mihara’s equation modified normal thirty years from 1981 2010 hourly KMA KSES. Average degree-hours calculated showed a good agreement with them data. The 24 times relatively big differences degree-hour low setting temperature. Therefore, was considered more appropriate estimate load. And conclude, which not available we suggest that should be derived every year during whole period can established as environmental standards, also minimum maximum used reference energy estimation.
