We investigated indoor thermal environments and air condition in 2 RC and 3 SRC appartment houses in Niigata city by questionnairing 111 apartments and by measuring temperature and humidity in 10 apartments. The results of this investigation are as follows: (1) People living in these apartment buildings are forced to dry laundry indoors in winter month, thereby increasing room humidity and causing dew condensation. (2) In some apartments it is impossible to get good ventilation in summer, because windows are made only on one wall. (3) The vertical temperature difference, measured at a height of 5 cm and at 110 cm above floor level in heated living rooms, is 0.5℃ to 2.5℃ after suppertime. And the indoor-outdoor temperature difference in the unheated rooms is more than 60 % of the difference in the heated living rooms, these differences are much smaller than the ones inside detached wooden houses in the area. (4) In the apartments heated by unvented oil heaters, the humidity in the living room increases in proportion to the increase of the indoor-outdoor temperature difference, the high humidity causes dew condensation in the apartments with windows made only on one wall.
