“…Such a phenomenon also highlights summer indoor comfort issues related to DSFs. Empirical field studies on a large number of real buildings seem to indicate that DSFs can be slightly better than single skins in terms of thermal comfort [86] but such an aspect falls outside the scope of this review. Figure 4 shows normalised data from the papers reviewed for this study in the form of cooling loads percentage reduction -findings are ranked from highest to lowest.…”

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.

“…Also in the same year Kragh introduced the idea of mechanical ventilation of double skin facades and investigated their efficiency ( Kragh,2002). In the year 2010 Huckemann et al in an experimental research studied the effect of double skin facades on thermal comfort of the residents and the interior air quality and compared the results with one skin facades (Huckemann, 2010). In Iran Hashemi et al investigated the behavior of double skin ventilated facades for Tehran climate both experimentally and numerically (Hashemi, 2010).…”

Energy crisis and daily increase in environmental pollution due to production of greenhouse gases, especially in construction industry is among important topics of the recent century architecture. Utilizing proper materials as one important factor in this industry, has been the concern of many researchers. Hence the following research has the aim of investigating heating performance of new kinds of materials in architecture industry and also replacing double skin facades to maintain thermal comfort of the residents, with minimum energy consumption. Sustainable architecture is one of the most important elements of sustainable development topic, because more than half of greenhouse gases in the world are produced by residential homes. Considering that the amount of greenhouse gases produced in developing countries is more than that of developed countries, hence it becomes clear the necessity of considering environmental approach in the field of architecture works. In this research while doing desk studies and investigating achieved research, the descriptive -analytical method and also field method have been applied and through thermal performance analysis of building materials and using energy simulation software (IES -VE)and their comparison, the appropriate pattern is proposed.

“…A double window system (DWS) is an energy-efficient envelope system in which a cavity is placed between the inner and outer layers to provide natural ventilation, solar radiation control, and enhanced insulation [1][2][3][4][5][6][7]. The DWS is a box-type double-skin facade that is also effective in reducing heating and cooling energy consumption [8][9][10][11]. In addition, buildings with double-skin facades offer better thermal comfort in the winter and lower thermal amplitude during the summer [10].…”

Thermal and Daylighting Performance of Energy-Efficient Windows in Highly Glazed Residential Buildings: Case Study in Korea

Cooling load in highly glazed residential building can be excessively large due to uncontrolled solar energy entering the indoor space. This study focuses on the cooling load reduction and changes in the daylighting properties via the application of a double window system (DWS) with shading with various surface reflectivities in highly glazed residential buildings. Evaluation of thermal and daylighting performances is carried out using simulation tools. The reductions in cooling load and energy cost through the use of DWS are evaluated through a comparative simulation considering conventional windows: a single window and a double window. Three variables of window types, natural ventilation, and shading reflectivity are reflected in the study. According to our results, implementation of DWS reduced cooling load by 43%-61%. Electricity cost during the cooling period was reduced by a maximum of 24%. However, a shading device setting that prioritizes effective cooling load reduction can greatly decrease the daylighting factor and luminance level of indoor space. A DWS implementing shading device with highly reflective at all surfaces is appropriate option for the more comfortable thermal and visual environment, while a shading device with low reflectivity at rear of the surface can contribute an additional 4% cooling load reduction.
