The questionnaire survey was done among employee in business buildings with or without a garden on its rooftop to clarify the actual conditions and the evaluation of the roofs as spaces for relaxation or for lunch break. The ratio of the respondents who took rest in the roof gardens at lunch time was significantly higher when that roof garden received a higher evaluation. In addition, 68% of respondents answered that they wanted to take rests in the green roof when they felt the sense of relief and also the 39% the sense of season. On the other hand, 65.0% of the respondents who did not intend to take rest in the green roof said that there was no place or facility to sit down on. And the 43% answered there was a little shade and also the 38% remarked that they couldnt be bothered to go up to the roof. Results showed that the green roofs are evaluated by the office workers as spaces for relaxation and lunch breaks when they were able to feel comfort, nature and the change of the season on them. And it was also shown that above-mentioned preferable conditions would be maintained by introducing some facilities such as benches, rain covers, pergolas and the vegetations consisting of various kinds of plants such as grass, flowers, and evergreen shrubs.
