Abstract: In building design, there is an ongoing trend of research focused on various techniques for decreasing energy consumption in buildings, which can reduce the effect of global warming. This work is inspired by the passive heating system “Trombe Wall” which consists generally of a masonry unit located at the façades, covered with a glass layer, and collects heat energy from the sun due to a black coating at the exterior side of the wall. However, it has some drawbacks: e.g., Trombe Wall is static, heavy, hard to integrate into contemporary architectural facades. To solve these problems, a dynamic Trombe Wall system called “Heat Pocket” has been designed. Heat Pocket consists of aluminum panels that are filled with phase change material (PCM), their exterior facing surface is painted with a selective black coating which converts solar energy to heat, and this thermal energy is stored in the PCM. In this work, the proposed system was simulated to assess if the system would satisfy ASHRAE thermal comfort levels during the day for the virtual room having an interior space of 7.3 m x 5.4 m x 3.5 m; in cold climate conditions of Van, Turkey; in the month of December. Findings show for the 100% PCM-filled panel, Heat Pocket is able to increase and retain the indoor by a minimum of 18.5 °C compared to outdoor temperatures. The system was able to satisfy ASHRAE thermal comfort levels completely throughout the analysis time, after the first 3.3 meters away from the glass façade.
