In this paper, to clarify the influence of sky radiance distribution on thermal loads of buildings, we compared 1) the maximum load Q_<meas,c>/Q_<meas,h>, Q_<uni,c>/Q_<uni,h> 2) the seasonal load Q^^〜_<meas,c>/Q^^〜_<meas,h>, Q^^〜<uni,c>/Q^^〜_<uni,h> which were calculated by using measured sky radiance distribution and uniform sky respectively. The relative difference of the maximum heating load P_<uni,h> is as large as to exceed +8%, and that of the seasonal heating load P^^〜_<uni,h> is +8.7% in the case of southern perimeter. So the influence of the sky radiance distribution on thermal loads isn't negligible. Moreover, in order to verify the availability of method of identifying the sky types on the calculation of the thermal loads, 1) the maximum load Q_<cie,c>/Q_<cie,h> and 2) seasonal load Q^^〜_<cie,c>/Q^^〜_<cie,h>,calculated by using irradiance values of the identified sky types are compared with Q_<meas,c>/ Q_<meas,h>, Q_<meas,c>/Q_<meas,h> respectively. Both the relative difference of the maximum load P_<cie,c>, P_<cie,h> and that of the seasonal load P^^〜_<cie,c>, P^^〜_<cie,h> are fully small. Therefore, we concluded the availability of this method on the calculation of thermal loads is verified.
