A Metal Hydride Actuator (MHA) attracts attention as a power source using natural energy. The purpose of this research is to develop the automatic ventilator driven by MHA, which uses only thermal energy, without using electric energy. In order to investigate the basic characteristic of a vinyl house, the temperature in the house, the outside temperature, and the amount of insolation were measured. In addition, a trial product of MHA was installed in the house, and the operation was checked. The effects of ventilation on the temperature inside the vinyl house were examined using the window installed temporarily. The result shows that the ventilation window was useful to control the temperature in the vinyl house.
