The influence to the room radiant interchange analysis caused by furniture or equipment has not been solved. It is important to evaluate this influence especially in rooms such as computer rooms or telephone exchange rooms. This paper aims at making clear this influence. It presents a computation method of form factors between obstructed surfaces and a room radiant interchange calculation method using this form factors. Furthermore a simple estimation method of room radiant interchange with obstructed surfaces is stated with the verification with field measurements results in a telephone exchange room.
