“…It should be noted that although the latter is the only case in which numerical results prove a worse situation cooling-wise, there are agreed and well-argued concerns about overheating issues within the studies reviewed here [6,12,60,80,84,85]. Such a phenomenon also highlights summer indoor comfort issues related to DSFs.…”

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.

“…Antibacterial properties (resistance to rot) and chemical resistance allows the use of polystyrene in a corrosive environment. [14,26] In current practice as insulation material in the territory of Russia are widespread mineral wool based on basalt binder, as well as boards based on expanded polystyrene. In some parts of the building, such as caps and place of constant accumulation and retention of water used slabs of polystyrene, obtained by extrusion.…”

Abstract:This article discusses about methods of construction of the ventilated facades. The ventilated facade is not only the element of facing, it is the supporting structure. Their main objective -creation of air ventilating space between a facade and an external wall of the building. Moving of air in this gap protects a heater from destruction, interfering with a moisture congestion. In addition, the ventilated facade protect the building from aggressive influence of external environment, have a sound and thermal insulation properties. There are several problems of systems of the ventilated facades connected with an application of a heater. For more effective using it is necessary to minimize contact of a heater with environment.

“…Gratia [27] explains that double-skin facades are derived progressively from the concept of a faç ade deigned entirely by glass. On the other hand, referring to the study by Mingotti et al [28], the external and internal layers of DSFs must have versatile openings in order to ensure air ventilation within the cavity as well as the interior atmosphere of the adjacent interior spaces. In view of that, it is reflected that the temperature and air ventilation are inherently related to the size of cavity, hence, the studies by Balocco and Colombari [29], Balocco [30] confirm that once the widths of cavity gets decreased, there is a high risk of being confronted with an overheating faç ade layer particularly, in summer.…”

Abstract-One of the most important methods of saving energy in a building is by carefully designing its facade. A 'double skin facade' is optimally one of the best options in managing the interaction between the outdoors and the internal spaces. It also provides some architectural flexibility to the design. Double skin faç ade (DSF) building is one of the available energy conservation opportunities through recent intelligent buildings. The need to energy conservation and sustainable development in buildings is causing a new interest towards passive solar systems. This paper will survey the various types of double skin facades systems, exploring their features and functioning followed by a review of examples; both constructed and proposed, from different buildings. The paper will then assess and analyze recent research and examples to attempt to reach a conclusion as to whether with a double skin faç ade, minimizing energy consumption within building.Finally, double skin facade (DSF) has been proven to be highly useful and significant in current building developments. The only downside of double skin facade is that it is said to be more expensive than the traditional single glass facade. However, it is widely agreed by many experts that double skin facade (DSF) is more cost-effective in the long run. This is because it is long lasting and more durable as compared to the single glass facade Index Terms-Double skin faç ade, energy saving, ventilated faç ade.
