For purposes of obtaining the fundamental data to furnish the optimal ventilating equipment in multi-family housing, investigated are the way how to design the ventilating systems and the problems of constructed ventilating equipment of kitchens and baths in actual apartments, and also the ventilation performance of bath rooms are examined by field tests. The results are as follows. 1) The investigation by using questionaires to the engineers who design the ventilating systems shows that it is necessary to establish the design methods as to the next items. a) Optimal ducting systems for a bath and a toilet room b) Optimal air change ratio for a bath, a toilet room and a kitchen c) System to ventilate stably independent on the wind pressure d) Shapes and positions of air inlets for ventilating a kitchen and a bath 2) The investigation by using questionaire to the occupants in multi-family dwellings reveals the various problems on ventilating equipment. Those problems are, in the kitchen, hotness at cooking in summer because of insufficient ventilating air, noisiness, vibration and oil smudge of the kitchen fan and the reverse flow from the exhausting outlet connected with the central vertical duct, and in the bath, shortage of ventilation air in summer and winter, incapability of controlling the air volume, coldness at taking a bath in winter, and noisiness and vibration of the bath fan. Those problems should be solved by the adequate ventilating system design. 3) Field tests of ventilation performance in baths of eleven apartment units identify that the ventilaton air volume per hour are distributed from 15 to 159m^3/h and the exhausting effect of the vapor filled in a bath is so different at every apartment. It is also found that the vapor is rapidly exhausted and the damage by vapor condensation does'nt occur in the bath which is ventilated at the air volume more than 90m^3/h. The ventilating equipment for a bath room should be established so as not to lower the comfort at taking a bath in winter and summer and so as to eliminate rapidly the vapor and condensed water after taking a bath.
