“…This work contributes in identifying the key aspect that may increase the efficiency of the HVAC systems in ventilated façades. Also, this research completes the authors' previous work [33][34][35][36][37] about the theoretical design and construction of an active ventilated façade with Peltier modules. The authors are aware that a techno-economic analysis of a THU prototype has not yet been reported.…”

“…The result was the construction of a simplified inhabited housing unit (prefabricated module) with a thermoelectric heating system. A detailed report on this first THU version (v1.1) and its manufacture has been presented by the authors in previous works [33][34][35][36]. This section provides a brief description of this first version and presents the improvement of this prototype (THU v1.2).…”

This chapter aims to describe the conceptual design and operating mode of an innovative thermoelectric heating unit (THU) prototype in a heating mode. Firstly, the conceptual design of THU system and improvements are described to investigate the effects of design in the thermal performance. Secondly, the THU prototype was compared with a conventional airconditioning system using the typical economic indicators (investment costs, maintenance costs and operational costs). The results indicate that the overall cost of this project was approximately 84,860 Euros, of which 69.27% of the total investment cost are for the engineering costs. By focused on the investment costs of the THU system, the results reveal that the conventional airconditioning system is economically viable than a THU system. The analysis shows that the design has a direct effect on the costs. The maintenance costs show that THU v1.2 prototype is more economically viable in maintenance than the conventional airconditioning system. Likewise, the operational costs show that THU v1.2 had a more stable thermal behaviour than the conventional airconditioning system. Based on the results, the authors concluded that the THU system could be a viable option for a heating room.

“…It is clearly visible in the studies that most of them do not provide experimental testing and develop prototypes for a pilot building. It is sometimes the case that a specific mix of technologies is investigated in a theoretical design but not accompanied with detailed energy modeling or experimental investigations [80]. This seems to be a key specific issue that needs to be attended to in future research by focusing on more combination of simulation and experimental work that involves field-testing.…”

“…For example, mechanical ventilation with heat recovery in air-based ADBEs has been studied in [78,79] to reduce energy losses of the envelope. Furthermore, either with or without mechanical ventilation, it is proposed to close the air cavity during certain occasions in order to avoid negative effects on occupants' thermal comfort caused by undesired ambient conditions [80]. Additionally, given the fact that the pre-heating of the air flowing in the cavity increases the efficiency of the air-based ADBE, geothermal energy systems are proposed to be integrated into the overall system [81,82].…”

State of the Art of Technologies in Adaptive Dynamic Building Envelopes (ADBEs)

et al. 2022

The design of adaptive façades as complex systems that dynamically respond to weather conditions and occupants’ demands is rapidly increasing in modern constructions since they are highly energy efficient. Adaptive Dynamic Building Envelopes (ADBEs) exploit the benefits of technologies that manage the energy and mass transfer between building and outdoor environments actively and selectively. There is a wide range of technologies used in the design of ADBEs that differ from one another in terms of user controllability and the level of how active or passive their technologies are. This paper provides a systematic search in literature on the technologies devised in the ADBEs, specifying the most prevalent practices, and highlights the most cutting-edge research approximations. The analysis shows more than half of the studies use photovoltaics (PVs) in their design. Using mechanical ventilation and heat pumps were the next popular choices. Moreover, approximately half of the studies were carried out using simulation methods alone, whereas only 13% of studies couple simulations with experimental work. This highlights a clear gap in coupling digital modeling and simulation software with practical field testing and successful mass production.

“…La idea de esta iniciativa nace del trabajo de un equipo de investigación centrado en el acondicionamiento higrotérmico con termoelectricidad, utilizando células Peltier como medio para la transferencia de calor (Ibáñez-Puy et al, 2014;Ibañez-puy et al, 2017;María Ibañez-Puy et al, 2018;Ibañez-Puy et, 2015;Martín-Gómez et al, 2010). El estudio de esta tecnología, así como su evidente interés docente, han dado como resultado el desarrollo de una sesión práctica que acercan la investigación y la termoelectricidad a los futuros profesionales, al mismo tiempo que les permite interiorizar conceptos básicos para su formación.…”
