“…La Ref. [28], indica que este comportamiento de aumento de temperatura se debe a que la absorción de la radiación solar mediante la capa de vidrio logra el calentamiento del aire que circula en el canal colocado entre el vidrio del sistema y la capa de aislador térmico, esto genera calor que se almacena en la masa interna del muro y permite poner en funcionamiento el PCM que contribuye a que el aire caliente circule en el ambiente interno y aumente la temperatura.…”

Climate change has an impact on all the areas that operate in a construction environment and, essentially, on the life cycle of a home; in which the materials affect the construction process according to their energy content. The adobe is used for its thermal conductivity to improve the internal temperature of a home; However, in cold climates their behavior is not very efficient. In this sense, the phase change material (PCM) can be used as an alternative because it is capable of storing latent heat and increasing the thermal mass of a building. In the present work, 06 insulation systems for walls, ceilings and floors of an adobe house are analyzed thermal insulation system is proposed, and a prototype is made with some components in 3D printing; the results indicate that the systems Trombe-PCM wall, translucent concrete block wall-PCM, false ceiling-PCM, concrete ceiling-PCM, alveolar floor-CM and plasterboard floor-PCM are adequate; with the proposed insulation system, an improvement of 42.71% of the internal thermal comfort is achieved when compared to adobe house without PCM; and an increase of 320.38% with respect to the Imata temperature, while the Trombe-PCM wall system prototype allows to make corrections in the design for its implementation on a real scale.

“…Trombe walls have been investigated by several experts over the last few decades as an essential passive solar heating device. Wang et al [7] analyzed Trombe walls' classification, testing, modeling, and evaluation. Trombe walls' heat storage and thermal resistance performance have been much enhanced thanks to advances in material technology, particularly the use of heat storage materials and aerogel materials.…”

The application of attached sunspace passive solar heating systems (ASPSHS) for farmhouses can improve building performance, reduce heating energy consumption and carbon dioxide emissions. In order to take better use of the attached sunspace to prevent heat transfer or promote natural ventilation, this paper presented a zero-state response control strategy for the opening and closing time of active interior window in the ASPSHS. In order to verify the application of this strategy, an attached sunspace was built in an actual farmhouse. A natural ventilation heat exchange model was built based on the farmhouse with attached sunspace. The proposed zero-state response control strategy was implemented in TRNSYS software. Field measurement in living lab was carried out to inspect the distribution of the thermal environment in the farmhouse with attached sunspace under a zero-state response control strategy in the cold region of northern China. The experimental results show that, even under −5.0–2.5 °C ambient temperature, the application of zero-state response control strategy effectively increases the internal temperature to an average of 25.45 °C higher than the outside, with 23% indoor discernible temperature differential in the sample daytime. The whole-season heating performance was evaluated by simulating the model for the heating season in 2020–2021. The simulation demonstrates that the ASPSHS under zero-state response control strategy can maintain a basic indoor temperature of 14 °C for 1094 h during the heating season, with a daytime heating guarantee rate of 73.33%, thus ensuring higher indoor heating comfort during the day. When compared to a farmhouse with an attached sunspace under the zero-state response control strategy, the energy savings rate can be enhanced by 20.88%, and carbon emissions can be reduced by 51.73%. Overall, the attached sunspace with the zero-state response control strategy can effectively increase the indoor temperature when the solar radiation is intensive and create a suitable thermal environment for the farmhouse in the cold region of northern China.

“…Collector-storage walls, also known as Trombe walls, are commonly seen [4,5,[7][8][9][10]; they are an alternative solution to walls made using monolithic concrete technology [11,12] Energies 2021, 14, 580 2 of 23 or wooden walls [13][14][15], and are constantly being modified to increase their energy efficiency [16][17][18][19][20]. The Trombe wall consists of the following layers: an external glazing that is in contact with the external air, an air gap and a layer that accumulates thermal energy.…”

The article presents the possibility of using a mass collector-storage wall (CSW), integrated into the structure of a building with a light skeleton structure. The considered system is a proposal for an energy-saving solution that can be used in buildings with various utility purposes. The article presents the results of experimental tests of a collector-storage wall mounted in the space of the skeleton structure of the southern facade of a building for the period of one year, as well as the results of numerical simulation. In the summer, the influence of the use of heat-insulating roller shutters on limiting overheating of the chamber interior was investigated. The effect of using the roller shutters is a reduction in the average value of the heat flux by about 77%. In the winter, the energy efficiency of the wall was tested. The obtained effect is energy consumption during the heating season at a level comparable to a wall with a traditional structure with a coefficient of U = 0.30 W/(m2K). The results of the numerical tests showed high agreement with the direct results, which provides a basis for the use of such simulations in further research on the search for the optimal structure of a collector-storage wall.
