This paper presents the thermal performance of a concrete tile ventilator equipped with PV-powered fan (CTVPVf). The CTVPVf is composed of a concrete tile ventilator, steel pipe, PV panel and DC fan. A DC fan is driven directly by a photovoltaic (PV) panel i.e. no battery is used. Two test houses of 8 m3 volume were utilized in experiments. First test house thatched the common flat concrete tile together with a CTVPVf located at the south-facing roof whereas a reference test house thatched common flat concrete tile only. The thermal performance of CTVPVf is expressed in terms of heat gain, temperature and the number of air change. Experimental results show that a CTVPVf can produce the number of air change up to 6-7 ACH, and provide indoor temperature nearly closed to ambient temperature. Moreover, the test house has a lower ceiling heat gain than a reference test house with the percentage heat gain reduction achieved higher than 40%.
