“…Wadel et al [46] adopted a simplified LCA in the design of building skins with the specific focus on a modular 'unitised' double skin façade in 2013. The façade is made of hybrid profiles of recycled aluminium and laminated timber, a uniquely produced insulated glass with variable solar factor, and opaque enclosures formed of tempered glass, recycled aluminium, recycled carpet boards, sheep wool as insulation, cellular vapour barrier, and recycled cellulose fibre plaster board [46].…”

“…The façade is made of hybrid profiles of recycled aluminium and laminated timber, a uniquely produced insulated glass with variable solar factor, and opaque enclosures formed of tempered glass, recycled aluminium, recycled carpet boards, sheep wool as insulation, cellular vapour barrier, and recycled cellulose fibre plaster board [46]. The figures assessed throughout the study are embodied energy per area of façade (MJ/m²), and CO 2 emissions (kg CO 2 /m²), where the functional unit is 1 m² of façade with a useful lifespan of 50 years.…”

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.

“…Only two studies exist where DSFs have been examined in detail from a life cycle perspective (de Gracia et al, 2013, Wadel et al, 2013. This alone represents a gap in knowledge with reference to a technology widely used in the AEC industry with a strong belief that it delivers "green" buildings, and is thus able to reduce EIs.…”

“…Additionally, the long lifespan of buildings combined with the change of use during their service life imply lower predictability and higher uncertainty of variables, parameters, and future scenarios. Such difficulties eventually lead to taking a 'reductionist' approach in many recent LCAs, where the term 'simplified' often recurs (Bala et al, 2010, De Benedetti et al, 2010, Malmqvist et al, 2011, Wadel et al, 2013, Zabalza Bribián et al, 2009). …”

“…Additionally, both the DSFs considered in the studies are innovative products which do not represent the current practice in the AEC industry. Wadel et al (2013) adopt a simplified LCA for an innovative type of DSF with vertical shading devices placed at specific intervals. The use phase is not incorporated in the LCA and impacts assessed throughout the study are limited to embodied energy and CO 2 emissions, the FU being 1 m² of the façade with a lifespan of 50 years.…”
