PV-Trombe wall is a new passive building design that can utilize solar thermal energy for room conditioning through passive heating and cooling of the room. The PV-Trombe wall is a renewal of the Trombe wall which aims to overcome the excess heat gain of the Trombe wall room during the day, especially in summer climates. The study on the application of PV-Trombe walls was carried out in the tropical climate of the city of Bandung. Analytical calculations of heat gain and numerical calculations of room temperature at steady and transient conditions have been carried out to evaluate the thermal performance of the PV-Trombe walls. The results of analytical calculations show that the heat gain of the PV-Trombe wall is significantly lower than that of the Trombe wall with a difference of 9.45 kWh during the dry season. Similar results were obtained from numerical calculations of room temperature transiently where the average room temperature of the PV-Trombe wall was 5.6°C lower than the Trombe wall during the dry season. When compared to conventional walls, PV-Trombe walls still produce greater heat gain and higher temperatures. Therefore a modification is needed on the PV-Trombe wall. From several design modifications that have been made, the lowest room temperature of PV-Trombe wall is obtained when thermal insulation is added with room temperatures during the day, evening and daily of 26.3°C, 26.3°C and 25.3°C in July on average for the year 2019-2021..
