“…The proposed framework includes life cycle assessment, occupant's satisfaction, and social benefits. Preet et al (2022) reviewed the studies on DSF systems and discussed the influence of geometric design parameters on heat transfer and fluid dynamics occurring in DSF system. Figure 18 shows the schematic diagram of DSF system used by the authors.…”

On a global level the building sector consumes about 45.00% of energy consumption, contributes about 40.00% to emission, uses 30.00% of water and impacts the environment by generating 30.00% of waste. Although windows are important components of a building that provide natural lighting and ventilation and establish necessary contact with the external environment necessary for healthy indoor ambient, they permit entry of undesirable solar heat in summer and allow escaping heat from the indoor ambient in cold seasons, which aggravate the building needs for energy and increase its contribution to atmospheric emissions. The present investigation provides a review on research, development, and applications of advanced windows in the building sector. The introduction highlights the importance and contribution of advanced glazing technology to improving energy, comfort, and thermal performance of buildings. The review includes natural illumination and ventilation, thermal comfort and discusses the effects of window to wall ratio on natural illumination and ventilation of windows and façades. The review also covers recent developments in glazed windows and façades including performance enhancements by using reflective solar films, vacuum glazing, windows with filling materials, windows with water flow, window with phase change material, window with stagnant inert gas filling, ventilated windows and façades and windows with aerogel. A special section was also included on smart glazing for windows and façades showing the new tendencies and applications in the building industry. Since commercial programs and open access codes are handy tools for simulation and performance calculations a section is dedicated to these codes. The conclusion section contains the most relevant conclusion of the review as well as future trends in research and developments in the area. The topics included in this review can be helpful for experienced and young researchers, practicing engineers and general readers interested in windows and façades.

“…This strategy is widely used in buildings with glass façades to reduce energy consumption [31]. Several options for incorporating air layers in building envelopes include Trombe walls, solar chimneys, unglazed transpired collectors, double-skin façades (DSFs), three-skin façades, and quadruple-skin façades [32]. Among them, DSFs have been considered one of the most promising responsive building elements as one of the building retrofitting options [33][34][35].…”

Development and Implementation of Photovoltaic Integrated Multi-Skin Façade (PV-MSF) Design Based on Geometrical Concepts to Improve Building Energy Efficiency Performance

This study presents the influence of multi-skin façade (MSF) design with photovoltaic (PV) systems on the thermal behaviors and power generation potential when installed on the entire southern façade of an office building model. This study considers various flexible changes in MSF system design based on geometrical concepts. For the simulation model development, this study uses the medium-sized prototype office building model, developed based on the ASHRAE 90.1-2019. A total of 24 different patterns are created based on a pyramid configuration: triangular pyramid (TP) and rectangular pyramid (RP). Changing the tilt angle for PV integrated surfaces is the main method used to compare the power generation efficiency of different MSF configurations. Results from this analysis indicate that the proposed PV-integrated MSF system with generated patterns tends to reduce cooling and heating demands. The system also presents increased PV power generation performance compared to vertically installed PV systems (i.e., the base case). The designed pattern has the highest performance in the RP configuration, 49.4% and 46.6% higher than the base case when compared based on energy yield and energy yield per unit area parameter, respectively. Increasing the cavity depth and installing the PV-integrated roof surface angle to coincide with the local latitude can achieve efficient power generation for the TP configuration, provided that only one unit is required for a pattern. As for the RP configuration, reducing the cavity depth and combining the number of units (up to nine units) on the pattern surface can achieve the best-performing power generation, while the heating and cooling demands of the perimeter zone are not significantly impacted. The results show the influence of geometrical design aspects of MSF systems on energy efficiency and the potential to generate energy from PV systems. This study is a part of developing an energy-efficient design method for multi-skin façade systems for commercial buildings.

“…Most articles on DSFs have focused on their thermal behaviour (Parra et al [1] and Velasco et al [2]); aerodynamic characteristics (Hassanli et al [3]); and aspects related to their geometric design properties and physical and optical properties (Jankovic and Goia [4] and Preet et al [5]). A few papers have also evaluated the influence of DSFs on the thermal comfort provided to occupants (Yang et al [6]) and energy consumption (Radmard et al [7] and Ahriz et al [8]).…”

The DSF (double-skin facade) system is an important element in building design and is used in adjacent spaces to control the inlet solar radiation, heat the air, reduce energy consumption, decrease the acoustics levels, and produce photovoltaic energy, among other improvements. The DSF system can, for example, be used in winter conditions to heat the air, which is then transported to non-adjacent spaces to improve the thermal comfort level and the indoor air quality that the occupants are subjected to. Smooth DSF systems, which are a focus in the literature, are subjected to higher solar radiation levels at a specific hour of the day. The semi-circular DSF system used in this work, which was built from a group of smooth DSF systems with different orientations, guarantees the reception of the highest incident solar radiation throughout the entire day. This work presents a numerical study of a new DSF system, called the semi-circular DSF. The DSF system consists of a set of 25 smooth DSFs with different orientations, each one consisting of an outer glazed surface and an inner surface provided by the outer facade of the auditorium, both separated by an air channel. In this work, the influence of the radius of the semi-circular DSF system and the opening angle of the DSF system on the thermal response of the auditorium was analysed. Thus, six auditoriums were considered: two sets of three auditoriums with radii of 5 m and 15 m, with each of the auditoriums having a different DSF opening angle (45°, 90°, and 180°). It was found that the greater the radius of the semi-circular DSF and the opening angle of the DSF system, the greater the area of its glazed surface and, consequently, the greater the availability of solar heating power. Therefore, during the occupation period, only the set of auditoriums with the largest semi-circular DSF radius managed to present acceptable levels of thermal comfort, which were verified from mid-morning until late afternoon. As for the opening angle of the DSF system, the influence was not very significant, although slight improvements in thermal comfort were noted when the value of this angle was reduced (see Case F as an example) due to the corresponding decrease in the volume of indoor air to be heated. In all auditoriums (see Case A to Case F), it was verified that the indoor air quality was acceptable for the occupants, so the airflow rate was adequately promoted by the ventilation system.
