- Abstract
The proportion of radiation load through glass windows in building energy analysis is comparatively great;it is regarded as linear relation with temperature in BIN method,which is extremely a rough method.It is not only because the relation between such radiation load and temperature is far from linear relationship,but also there is lack of objective standard for the selection of corresponding representative temperature to the load.To solve this problem,calculating the maximum factor D_(J max) firstly,then get the hourly corresponding relation of load and temperature by multiplying the hourly cool load coefficient.The practical relation of load and temperature could be obtained by counting up the average load to each temperature at each direction;the load calculation method is still simple using a series of statistic data.A comparison has been made between this method and the former one.As it is the real reflection of relation between the temperature and load,the precision of load calculation is enhanced.The process using this method to calculate load for south facing window in Chengdu is given in this paper.
