“…In addition, passive retrofit actions are usually less invasive, allowing for renovations without changing the structure of historical buildings [26]. One of the most useful passive strategies to decrease energy usage in buildings is installing a second-skin (SS) facade system [17,20,23,[27][28][29][30][31][32][33][34]. The SS facade systems consist of a standard facade, an air cavity, and an additional external skin.…”

“…The SS facade systems consist of a standard facade, an air cavity, and an additional external skin. According to [17,20,23,[27][28][29][30][31][32][33][34], the proper design of the SS facade systems can lead to several environmental and economic advantages; these benefits can be summarized as:…”

“…Several types of research have been performed in the last year to evaluate the effectiveness of SS facade systems in the Iranian climate [27][28][29][30]35,36]. In particular, in Hashemi et al [27], a building with a SS facade system was monitored for two weeks during summer and two weeks during winter in the hot arid climate of Iran to observe the behaviors of the facade both in hot and cold conditions.…”

“…The simulation results highlighted a reduction of the cooling and heating energy demand of about 45% compared to a building with a conventional facade system [28]. Radmard et al [29] analyzed the cooling effect of natural convection influenced by a box-window retrofit SS facade on an office room in Karaj (Iran). The research showed the great potential in terms of both energy and environmental benefits during the hot season.…”

“…The literature review [17,20,23,[27][28][29][30][31][32][33][34][35][36] highlighted a number of benefits achievable using the SS facade system. In addition, the part of the literature review related to the Iranian climate [27][28][29][30]35,36] highlighted that: (i) all the analyzed researches are focused on temperate climates, (ii) glass is usually used as SS material, and (iii) only one research evaluated the reduction of carbon dioxide emissions.…”

A large amount of the Iranian energy demand is related to the building sector, mainly due to its obsolescence. In this paper, a second-skin system has been implemented as a retrofit action for an office building, evaluating the effect of a tensile material as second-skin in terms of primary energy saving, carbon dioxide equivalent emissions, and simple payback period. The analysis was carried out through numerical simulations across a whole year and for four Iranian cities (Tabriz, Teheran, Yazd, and Bandar Abbas) in four different climates (cold, temperate, hot-dry, and hot-wet), and with the building aligned at either north-south or east-west. Moreover, an economic analysis was carried out suggesting different incentive policies to promote building energy refurbishment. The simulation results highlighted a favorable orientation for buildings in Iran, suggesting a guideline for new constructions. Indeed, the best results were achieved for an east-west orientation of the building (up to a primary energy saving of 13.6% and reduction of carbon dioxide equivalent emissions of 45.5 MgCO2,eq, in Yazd), with a decrease of the annual specific total (cooling and thermal) energy demand of 37.9 kWh/m2/year. The simple payback period values were also lower in the east-west orientation than the north-south one.
