“…Similar numerical results are also achieved in studies more focused on comparisons between DSFs and single skin options [44,[66][67][68][69][70]. Comparable savings have been observed by 18.7% during winter months in Korea [71], by 20.5% in the restoration of industrial buildings in Italy [72], and by 18% in real monitoring of three DSF buildings in Germany [73].…”

“…However, there are also less positive findings that suggest the need for mechanical means to ventilate the building for more than half a year [71,78]. The difficulty of ventilation via DSFs has been assessed also by Gratia and De Herde [90] who studied the effects of wind direction, building orientation, openings size, and cross vs. single-sided ventilation in a DSF prototypical building.…”

Double Skin Façades (DSFs) are applied in both new and existing buildings, especially in temperate climates. Research in this area is steadily growing; however, there is a lack of conclusive results in available literature about energy performances related to the DSF, thus limiting a better and more informed application of this technology in the Architecture Engineering and Construction (AEC) sector. This paper systematically reviews more than 50 articles which have dealt with the energy related performance of DSFs in temperate climates and provide a meta-analysis of the numerical findings published in the studies examined. Energy related figures are presented separately for embodied and operational energy. Specifically, the operational energy end-uses taken into account are heating, cooling, lighting, and ventilation. Numerical results in the literature are normalised and expressed in form of percentage of maximum energy reduction/increment compared to a base case (e.g. a single skin case) used as a reference in the corresponding studies. Such an approach is meant to provide a reliable comparison of published figures. Key façade parameters (DSF spatial configurations, cavity width and ventilation), building parameters (orientation and climatic areas) and the methodological approaches used in the reviewed studies were deployed as clustering criteria. Several clustering criteria present extremely spread values, indicating the necessity to further investigate, understand, and attempt to reduce such high discrepancies in operational energy performances. Additionally, and more importantly, almost no information exists on DSFs life cycle energy figures, highlighting an important gap that requires further research.Suggested Reviewers: Mohamad Kiani PhD Principal Sustainability Consultant, Baily Garner LLP mohamadrezakiani@gmail.com Dr Kiani has extensive experience in sustainability in the construction industry.

“…Kim et al [5] also proved that DSFs can be used to reduce energy consumptions in buildings during both heating and cooling seasons while maintaining indoor comfort levels. However, studies conducted by Tascon [6] revealed that DSFs tend to experience overheating problems during warm seasons.…”

“…Previous researchers have raised the overheating problems associated with DSFs and come up with several solutions to dispel the problems. Tascon [5] raised that the main causes of overheating in DSF which included ineffective removal of heat stored within the DSF system, inappropriate location and size of shading devices, and inadequate operations of the DSF for specific thermal environmental conditions. Jager et al [6] and Wigginton et al [7] reported physical considerations at design stage of DSFs such as ensuring a minimum distance between the outer and inner skins and adjusting the sizes of openings for better ventilation in the cavity.…”

“…The design and perspectives of the double skin envelope and its performance according to the solar controls, natural ventilation, shading device, solar photovoltaic, active facades such as active window strategies, glass selection, and cavity depth were evaluated [1,2]. Diverse performance tests presented the effectiveness of double skin envelope for saving heating and cooling energy based on the proper ventilation strategies [3][4][5][6]. In particular, besides the remarkable reduction of the heating energy, cooling energy was also significantly saved compared to the singles skin enveloped-buildings when the natural ventilation strategy or the passive thermal mass was applied [6,7].…”

This study aims at developing an indoor temperature control method that could provide comfortable thermal conditions by integrating heating system control and the opening conditions of building envelopes. Artificial neural network (ANN)-based temperature control logic was developed for the control of heating systems and openings at the building envelopes in a predictive and adaptive manner. Numerical comparative performance tests for the ANN-based temperature control logic and conventional non-ANN-based counterpart were conducted for single skin enveloped and double skin enveloped buildings after the simulation program was validated by comparing the simulation and the field measurement results. Analysis results revealed that the ANN-based control logic improved the indoor temperature environment with an increased comfortable temperature period and decreased overshoot and undershoot of temperatures outside of the operating range. The proposed logic did not show significant superiority in energy efficiency over the conventional logic. The ANN-based temperature control logic was able to maintain the indoor temperature more comfortably and with more stability within the operating range due to the predictive and adaptive features of ANN models.
