Double skin façades and the Internet of Things (IoT) are pivotal in enhancing a structure’s energy efficiency and natural ventilation. Their impact, however, varies based on design size and geographical location, prompting an exploration of the nuanced interplay between IoT technology and energy savings across diverse building types and climates. The paper emphasizes crucial considerations in assessing IoT’s impact on energy efficiency, such as building’s category and location, whether a towering skyscraper, a modest apartment complex in arid New Mexico, or a structure in frigid Alaska. Investigating whether one type outperforms others and discerning global prevalence becomes essential. The exploration delves into design challenges posed by different building categories, addressing questions about the nature of a particular type presenting intricate obstacles to efficient design and whether regulatory requirements limit creative possibilities. Additionally, it examines the adaptability of doubleskin façades concerning materials without compromising performance. Enhancing energy efficiency and indoor thermal comfort involves manipulating materials for façade skins, introducing characteristics like fabrics for outer skins to allow airflow, and mitigating heat radiation from inner skins made of concrete, glass, or metal. This time lag contributes significantly to maintaining ideal indoor thermal conditions. The integration of IoT technology is pivotal, generating real-time data and notifying users of temperature differentials. This data-driven approach ensures optimal façade operation compared to conventional methods. In conclusion, the paper underscores the critical relationship between IoT technology and energy conservation in diverse building categories and climates, shedding light on challenges and opportunities associated with energy efficiency design. It advocates for the intelligent use of materials and IoT technology to realize substantial energy savings and improved indoor comfort. Exploring design challenges and considerations provides valuable insights for practitioners in the field.

“…By strategically combining considerations for both daylight and ventilation, designers can harness the dual advantage of redirecting airflows for improved natural ventilation, effectively creating shadings that are multifunctional, adaptable and occupant-centric. In this way, the integration harmonises crucial environmental, economic and human factors, delivering a comprehensive and efficient solution [32][33][34].…”

The future of building envelope design lies in smart adaptation. The current literature overlooks the crucial integration of airflow, ventilation and daylighting in adaptive façade design. Moreover, it neglects the occupants’ locations, activities and interior layouts in this context. This study introduces an innovative approach to adaptive building envelope design, aiming to enhance occupants’ comfort through parametric analysis of daylight and airflow. The research combines parametric simulation, computational fluid dynamics (CFD) analysis and multiobjective optimisation. The optimisation goal is to improve visual comfort and indoor air quality while maintaining air temperature and velocity within the human comfort range. The study contributes to providing designers with a method for building envelope design that considers visual comfort and airflow, resulting in more interactive building envelopes that are adaptable to environmental conditions for enhanced utility and comfort. Results indicated that the optimised façade configuration and design methodology can achieve a 69% improvement in daylight performance, improving useful daylight illuminance (UDI) while reducing glare risk. Additionally, air changes per hour (ACH) showed a 38% annual improvement. This research signifies a significant step towards more efficient and occupant-centric building envelope design, aligning with the evolving demands of the construction industry and sustainable building practices.

“…In the context of energy and climate change, many types of "active" facades are being studied given the increasing importance of this topic. A bibliographic review [7] was carried out on "multi-skin" ventilated facades and it highlighted the significant gains that could be obtained in overall building energy balance. Investigations have been performed to study the various types of ventilated windows, such as the simple pivoting window [8], the ventilated double-glazing window [9] (Figure 1b) and the double-skin window [10] (Figure 1c).…”

Analysis of the Thermo-Aeraulic Behavior of a Heated Supply Air Window in Forced Convection: Numerical and Experimental Approaches

This paper presents work intended to characterize air flow and convective heat transfers within a ventilated window. This window is a device that allows for the entry of fresh air into a building while simultaneously preheating it in order to satisfy requirements in terms of air quality and thermal comfort in inhabited spaces. Therefore, this essential component of the building envelope functions herein as a heat exchanger with its own geometric characteristics and exchange conditions. In this research, a dual numerical and experimental approach has been implemented in order to highlight the temperatures, velocities and heat flux fields both at the glazing surfaces and in the ventilated air gaps. Several turbulence models were tested using CFD software (ANSYS-FLUENT®); their results were compared with each other as well as with the experimental results. This study shows that the air gap geometry in the window induces flow disturbances, recirculation phenomena and non-uniform heat exchanges, all of which prove to be important in terms of overall component performance. With regard to modeling and, in particular, at the level of turbulence models, the results obtained indicate that the model GEKO is best suited to the configuration under study when the phenomena of turbulent forced convection dominate the dynamics of the transfers. The k-ε models reveal a tremendous weakness in precisely estimating the problem’s characteristic quantities. From an experimental point of view, local measurements of thermal fluxes and temperatures demonstrate high efficiency with regard to experimental technique, which in turn could be extended to many different configurations for the local evaluation of convection heat transfer.
