CFD analyses for passive house with Trombe wall and impact to energy demand

Experimental investigations on the performance of a collector–storage wall system using phase change materials

“…Part of the heat energy is then transferred from the wall to the room by conduction, and is also exchanged to the air in the channel/gap by convection and then is ejected into the room through the upper vent driven by buoyancy [3,4]. Many experimental and numerical studies have been performed on massive Trombe wall systems and it was found that the thermal performances of the Trombe wall depend on various parameters such as the size of air gap and vents [5,6], wall area and orientation [7][8][9], wall thickness [10,11], glazing [12][13][14][15], insulation [7,13,15] and operation strategy [7,16]. Recently, PCM (phase change material) application in buildings has been recently attracting wide attentions due to the high thermal storage intensity and narrow temperature change during phase transitions [17][18][19].…”

Modeling of heat transfer processes in ventilated enclosing structures in stationary conditions

“…One of the most famous structural elements of the passive solar heating system is the Trombe wall ( Fig. 1) [7]. The massive wall 1 of the dark surface 2 is separated from the atmospheric air by a glass overlap.…”

Advanced Strategies for Net-Zero Energy Building: Focused on the Early Phase and Usage Phase of a Building’s Life Cycle

“…(2) Heat storage system: Various studies associated with the heat storage system have been conducted because the heat capacity of a building is a very important factor from the point of view of nZEB. This study examined the previous studies that analyzed the energy reduction according to the building thermal performance, focusing on the thermal mass and trombe wall (refer to Table 5) [56][57][58][59][60][61][62][63][64][65][66]. First, there are many previous studies that focused on reducing the heating and cooling demand of a building through the heat storage function of the thermal mass [56][57][58][59][60][61].…”

“…Chernounsov and Chan (2016) analyzed the thermal performance of the building-envelope-integrated PCM with a high specific heat capacity using the EnergyPlus software program for an office building in Hong Kong. Through this study, the relationship between the indoor thermal environment and the PCM's thickness, placement, and orientation was analyzed [61] Second, the past studies related to the trombe wall, which functions as a heat storage system by applying a solar heating collector made of double glazing on the wall, are as follows [62][63][64][65][66] The results showed that the trombe wall increased the cooling demand in summer, but it is very suitable for the Belgrade climate because of its efficient heating energy-saving in winter [66]. (3) Lighting design: From the perspective of nZEB implementation, this study analyzed the previous studies focused on the lighting emitting diode (LED), light shelves, and lighting control system as methods for reducing the lighting load (refer to Table 6) [67][68][69][70][71][72][73][74].…”
