“…Many studies agree that DSF is more cost-effective in the long run because it is longer lasting and more durable than single-skin façade (SSF) [7,15,16]. It creates a more comfortable and environmentally friendly environment, as well as lowers maintenance costs by conserving the building's energy resources [16].…”

“…Through years of research and ongoing improvement, the DSF system has evolved into its current form and has come to be associated with applications of transparent and glass architecture. It is also evolving into a successful environmental design approach for reducing energy consumption and life cycle costs [7]. DSFs are becoming more and more signi cant in contemporary building practice.…”

Carefully designing a building façade is the most crucial way to save energy. A double skin façade is one of the effective strategies for achieving energy efficiency. This depends on the configuration chosen for the double skin façade that synchronizes with climate conditions. The study aims to investigate the best-case scenario with appropriate double-skin façade configuration for optimizing building energy performance. A methodology for optimizing the building's initial condition was introduced using EnergyPlus and ClimateStudio according to the one-year period of Erbil city. Analyzation of double skin parameters performed through utilizing a multi-objective analysis approach. Four geometric configurations were assessed; building-high, story-high, shaft-box, and box-window. The results offered annual and seasonal consumption curves for each orientation. Shaft-box double skin façade significantly reduces the amount of cooling energy due to massive airflow between two skins. a significant drop in the annual cooling demand of 9–14%. The use of an appropriate double skin façade greatly benefits Erbil city climate as it can result in annual energy savings of up to 116,574 kWh.

“…Existing studies have mainly focused on environmental sustainability in residential buildings. In other words, various research has been actively conducted on energy-saving technologies such as zero-energy [26][27][28] and environmental performance evaluation methods such as LCA [29][30][31].…”

“…Meex et al [29] investigated possible solutions to apply LCA, including operational energy demand simulation, in early design from two different perspectives: design-oriented user requirements, derived from literature, a survey, interviews, and a focus group with architects; and LCA simplification strategies based on a literature review. Hay et al [30] proposed an innovative double-skin façade (DSF) system. In this study, mechanical testing of façade elements and a partial life cycle assessment (LCA) focusing on embodied energy and operational energy of a typical functional unit were performed to evaluate mechanical properties and the sustainability performance of the system, respectively.…”

In general, the long-term maintenance planning of residential buildings is performed based on uniform repair times. However, in fact, various factors, such as the quality and user patterns, affect the performance of residential building components in the Operation and Maintenance (O&M) phase. Hence, various residential building components are repaired at uncertain times, acting as a risk for the residential building maintenance plan. Therefore, an efficient maintenance plan should be established considering maintenance uncertainty. In this regard, this study aims to analyze the uncertainty of repair times for various finishing works in residential buildings based on a probabilistic methodology and outline the implications for the establishment of efficient maintenance strategies in these buildings. Hence, 47,344 repair data for 63 buildings in 12 public residential building complexes completed between 1991 and 2001 in the Republic of Korea were used for analysis. Before the analysis, a repair time matrix was constructed by classifying the finishing works in 25 types and setting service life times to 6–26 years. The repair time distribution for each finishing work was then derived. Results confirmed that basic repair time setting can be performed and various information for reasonable maintenance decision making regarding each finishing work can be provided through a probabilistic approach. The probabilistic approach can be used as a critical decision-making method because there is uncertainty associated with the repair time of each finishing work owing to the performance degradations of various finishing works due to complex causes. Although this study focused on repair time owing to data collection limitations, maintenance strategies with strategic flexibility can be established by developing probabilistic methods that simultaneously consider frequency and cost by securing additional high-quality cost data.

“…In comparison to typical solid clay bricks and hollow clay bricks, ALC panels have a low gravity and resistance of fire and seepage, which provide superior construction physical capacity. Although doubleskin façade (DSF) and AAC block panels can have these advantages better, they are not as easy to construct as ALC panels [9][10][11]. Currently, research on ALC panels is mostly focused on the improvement of the stiffness, seismic resistance, and energy consumption of the whole building structure [12].…”

This paper proposes a new flexible connector for the autoclaved lightweight concrete (ALC) panel with the steel beam. It is a universal upper and lower crossing connector, with load-bearing and limitation holes; then, the seismic capacity of this connector is investigated in the simulations and full-scale tests. Firstly, the finite element simulations of the new connector and traditional connector (L-hooked bolt) were made by ABAQUS, which proved the reliability of the new connector by comparing them in low-cyclic loading. Secondly, in order to analyze the phenomenon and data of the two connectors which are in the same test conditions of simulation, the full-scale tests of the steel frame were conducted. The damage of the ALC panel at different connectors and at different test load displacements is described in detail. The contribution of the connectors to the steel frame and the ALC panel is investigated in depth during the elastic, elastoplastic, and plastic stages of the steel frames. The test result is similar to the simulation result roughly, in which the new connector has better seismic capability. In minor earthquakes, the ALC panel frame with the new connector has better synergistic capacity of panels, while in large earthquakes, it can provide certain stiffness to the structure. Compared with the L-hooked bolt, the maximum bearing capacity of the structure with the new connector increases by 5.2%, and the yield displacement delays by 27.5%, which results in the increase of ductility by 9.8%. In terms of energy consumption capacity, the equivalent damping factor of the new connector increases by 10.2% and 35.3% at the yield and ultimate state, respectively. The FEM simulation results can represent the actual test results well. To summarize, the new ALC panel connector in this paper has excellent seismic capacity and good synergistic, which can provide a reference for the development and application of new types of the ALC connector.
