PROPOSAL OF THE t-x BASIS AND THE t-Jh BASIS HEATING DESIGN WEATHER DATA

Abstract

This paper proposed two types of heating design weather data, the t-x basis data and the t-Jh basis data. They were produced from the weather values on the extreme-weather days selected out of Expanded AMeDAS weather data from 1981 through 2000 using the two weather indices. The extremity of the proposed design weather data were evaluated obtaining the cumulative frequencies of occurrence of the daily weather values and the probabilities of occurrence of the thermal load exceeding the heating design load calculated with the proposed weather data.
