Abstract:Sustainable architecture and green building are recognized techniques to address the energy and environmental crises. In this regard, the Trombe Wall has also attracted attention for its potential ability to address the energy and environmental crises. Trombe Wall is regarded as a sustainable architectural technology for insulation. This article reviews the classification and configuration of Trombe Wall and the most relevant content of Trombe Wall research carried out in various countries over the past few de… Show more
“…Since this system makes use of conduction, convection and radiation unlike conduction alone in the case of classic Trombe wall, fluidized Trombe walls are highly efficient. There have been a lot of recent innovations in Trombe walls depending on the project objectives [ 57 , 58 ]. Fig.…”

Passive buildings are proving to be a solution to menaces of energy crisis and greenhouse gas emissions across the world. Such buildings tend to exhibit low energy demand owing to their cleverly designed envelopes, which comprise of walls, roofs, doors, windows and other openings. This requires use of new materials and technology, leading to an increased initial construction cost. However, with reduced energy consumption, the lifecycle cost of a passive building may be lower than that of a conventional building. These passive buildings also need to cater to occupants’ comfort which is subject to local climatic conditions and climate change. This article discusses economic feasibility and climatic adaptability of a passive building, in addition to advances in passive building strategies. Owing to lack of general awareness and standards related to passive building construction, these buildings have not achieved enough popularity. While many countries are striving hard to bring passive buildings to common masses, a large number of countries are yet to initiate the move. This article outlines several active organizations, standards and rating systems for passive buildings. This article also presents some of the recent research trends and a comprehensive bibliography for the benefit of researchers and practitioners.

“…Due to their simplicity and low-threshold approach, passive strategies have been commonly practiced in vernacular architecture, designed to accommodate the immediate environment. Prominent examples of passive solutions include the use of wind towers for passive air conditioning in hot and dry climates and the use of trombe walls as a passive solar heating strategy in temperate climates (Maleki, 2011;Wang et al, 2021). Nevertheless, due to the changes in lifestyle, technological advancement, and higher requirements for high-performance buildings, passive features are also adapting to conform to architectural trends and modern lifestyles (Konis & Selkowitz, 2017).…”
In view of the required energy savings in the building sector, there is an urgent need for innovative and sustainable solutions to increase the performance of building envelopes. Adaptive façades can make an important contribution, whereby passive low-tech strategies and active high-tech solutions are apparently incompatible. In current digitalization, new technologies and methods for the implementation of adaptive façades emerge in the framework of Cyber-Physical Systems. The investigation follows the research question: How can active and passive approaches of adaptive façades be mediated and what potential do Cyber-Physical Systems have for the implementation of hybrid solution approaches in the future? The article presents a comparative case study of the two research projects ADAPTEX and PRÄKLIMA as examples of passive and active adaptation strategies in the façade industry. In this context, the potential for further research of Cyber-Physical Systems in the application domain of adaptive façades as a catalyst for high-performance and multifunctional solutions, and as a mediator between both strategies, is highlighted. The main findings are the potential application of cyber-physical system technologies to the design and monitoring of passive adaptive façade solutions, as well as the possible integration of passively conceptualized components into active overall systems.
“…But it has drawbacks also: it has a low thermal resistance, an inverse thermosiphon effect, and an unsightly appearance [10]. In the scientific literature, several variations of the basic configuration of the TM wall can be found, such as the composite TM wall (TM-Michel wall), water TM wall, zigzag TM wall, solar transwall, fluidized TM, photovoltaic TM, and TM wall with PCM [11].…”
Passive solar systems are one of most important strategies to reduce the heating loads of buildings. The Trombe–Michel (TM) wall and its variants are some of the better-known structures in the field of solar systems. An alternative to the TM wall is the Barra–Costantini (BC) system. In the present paper, CFD numerical simulations, both in steady and transient states, of modified BC and TM walls were carried out in the winter season. Different interspace thicknesses were simulated in order to evaluate their effects on the temperature field and air velocity, and the numerical results were compared among them. It was found that the BC system offers greater hot air flow compared with the TM wall; the mass flow rate increased up to 43% in the BC system and up 28% in the TM system when the interlayer thickness was increased by 500%. The transient simulations (100 h simulated) demonstrated that the dynamic response of the BC wall was shorter than that of the TM wall, even when the TM wall was simulated with initial thermal conditions that were more advantageous than those for the BC wall. The BC system reached a periodic stabilized regime within 24 h, whereas the TM system failed to stabilize in 100 h. The results show that for both TM and BC structures, the interlayer thickness scarcely influenced the temperature of the environment reached (the temperature peak increased up to 3–4% as the interlayer thickness was increased by 500%), while larger air speed changes were observed in the BC system in the transient state compared with the TM system. Thus, in the TM system, the outlet air velocity was practically constant as the interlayer thickness was increased; in contrast, the outlet velocity peak increased up to 50% in the BC system. Moreover, the BC wall presented a quicker response to satisfy the ambient thermal loads.
