The authors planned and surveyed a passive design house installing an air conditioner under the floor. From the results of the measurement, thermal environment in winter was good, but in the case of floor cooling in the first summer, vertical temperature distribution was large. In the second summer, wall mounted air conditioners for cooling were added and the indoor thermal environment was improved. Measured total energy consumption of the house was about half amount of the value estimated by Japanese energy standard.
