“…Such a straightforward formula should not mislead and imply simplicity in DSFs behaviour which is hardly the case. To the contrary, DSF is a complex technology with many intertwined heat transfer mechanisms and fluid dynamic phenomena [23,44].…”

“…Although some monetary figures do exist [22], they can vary greatly and fall beyond the scope of this review. This paper builds on the knowledge capital of existing reviews already published on DSFs [3,[23][24][25][26]. Specifically, this research has used a systematic approach to review DSF energy performance, and has conducted a meta-analysis of the examined literature to normalise and present numerical findings in order to determine if significant trends could be mapped to assist DSF practitioners and academics alike.…”

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. Additionally, his PhD thesis dealt with the environmental impacts of glazed facades which is a part of the review paper here submitted.

“…A systematic critical review of the existing body of literature from the last decade on experimental and computational simulation of DSFs was performed and disseminated by Barbosa and Ip (2014). The study identified the key design and site parameters that Table 1 shows the building model fabric material properties and the description of internal heat gains applied during the office occupancy hours (from 8 a.m. to 6 p.m.) for the whole year.…”

“…These impetuses triggered a number of studies on viability and implementation of DSF in countries with warmer climates such as in China (Zhang et al, 2010), Spain (Torres et al, 2007) and Singapore (Chou et al, 2009). Most of these studies are based on building models that are fully air-conditioned without considering further exploitation of the technology to enhance the energy performance through incorporation of natural ventilation to operate under a mixed mode ventilation strategy (Barbosa and Ip, 2014).…”

“…To fill this gap of knowledge, and in particular addressing the growing building and economic developments in warm and tropical climate countries such as Brazil, a comprehensive research programme that investigated the influences of generic architectural configurations and climatic conditions on the thermal performance of naturally ventilated buildings with DSF has been developed (Barbosa and Ip, 2014;Barbosa et al, 2015a;b). The findings from these studies enabled this current and more detailed study on predicting the levels of annual thermal acceptance in naturally ventilated office buildings with DSF in different regions of Brazil.…”

This study has predicted the annual thermal acceptance levels in naturally ventilated office buildings with double skin façade (DSF) under different Brazilian regional climates. It builds upon the outcomes of a comprehensive research programme on the study of generic thermal performance of naturally ventilated office buildings with DSF, which has identified and evaluated the key design parameters affecting the thermal behaviour of DSF through computational simulation models. Taking into account Brazil's bioclimatic zones characteristics, including the solar incidence and wind conditions, design configurations are adapted, optimised and embedded within computational models for analysis. Thermal acceptance levels of each region, using operative temperatures as the thermal comfort index, are illustrated. The highest levels of thermal acceptance, as high as 90%, are experienced in the south and southeast regions. Around 65% can be achieved in regions of centre-west, north-west and coastal areas, but only 20% in the arid region of the north-east.Significance of these thermal acceptance levels is discussed and comparisons to single skin façade (SSF) models highlight the benefits and constraints of the application of the DSF.The methodology and the results developed from this study enable initial assessment of application of DSF in naturally ventilated buildings under warm and hot climates.
