“…Maintenance planning through façade control systems is widely used to monitor load pressure signals and environmental impacts and reduce energy usage/carbon emissions. It also increases kinetic mobility for connection, façade monitoring and improved displacement behavior in response to PC building design and ambient environment (Hosseini et al , 2019; Pomaranzi et al , 2020). The extent to which façade maintenance planning in PC construction activities can be optimized by deploying more sophisticated or innovative tools and techniques is already known.…”

Purpose This paper aims to identify the different system approach using Building Information Modelling (BIM) technology that is equipped with decision making processes. Maintenance planning and management are integral components of the construction sector, serving the broader purpose of post-construction activities and processes. However, as Precast Concrete (PC) construction projects increase in scale and complexity, the interconnections among these activities and processes become apparent, leading to planning and performance management challenges. These challenges specifically affect the monitoring of façade components for corrective and preventive maintenance actions. Design/methodology/approach The concept of maintenance planning for façades, along with the main features of information and communication technology tools and techniques using building information modeling technology, is grounded in the analysis of numerous literature reviews in PC building scenarios. Findings This research focuses on an integrated system designed to analyze information and support decision-making in maintenance planning for PC buildings. It is based on robust data collection regarding concrete façades' failures and causes. The system aims to provide appropriate planning decisions and minimize the risk of façade failures throughout the building's lifetime. Originality/value The study concludes that implementing a research framework to develop such a system can significantly enhance the effectiveness of maintenance planning for façade design, construction and maintenance operations.

“…Also, windbreak panels are usually used in industry and power plants to control wind and dust pollution. In these cases an estimation of the cladding wind load is useful information for architects and engineers (Pomaranzi et al 2020). Furthermore, the modelling of the interaction of flow with arrays of fibres and the prediction of the corresponding drag can be helpful to understand the mechanism of filter feeding for numerous marine organisms for which arrays of bristles move in water to capture food particles (see Cheer & Koehl 1987;Hood, Jammalamadaka & Hosoi 2019).…”

We investigate the three-dimensional (3-D) flow around and through a porous screen for various porosities at high Reynolds number $Re = {O}(10^4)$ . Historically, the study of this problem has been focused on two-dimensional cases and for screens spanning completely or partially a channel. Since many recent problems have involved a porous object in a 3-D free flow, we present a 3-D model initially based on Koo & James (J. Fluid Mech., vol. 60, 1973, pp. 513–538) and Steiros & Hultmark (J. Fluid Mech., vol. 853, 2018 pp. 1–11) for screens of arbitrary shapes. In addition, we include an empirical viscous correction factor accounting for viscous effects in the vicinity of the screen. We characterize experimentally the aerodynamic drag coefficient for a porous square screen composed of fibres, immersed in a laminar air flow with various solidities and different angles of attack. We test various fibre diameters to explore the effect of the space between the pores on the drag force. Using PIV and hot wire probe measurements, we visualize the flow around and through the screen, and in particular measure the proportion of fluid that is deviated around the screen. The predictions from the model for drag coefficient, flow velocities and streamlines are in good agreement with our experimental results. In particular, we show that local viscous effects are important: at the same solidity and with the same air flow, the drag coefficient and the flow deviations strongly depend on the Reynolds number based on the fibre diameter. The model, taking into account 3-D effects and the shape of the porous screen, and including an empirical viscous correction factor that is valid for fibrous screens may have many applications including the prediction of water collection efficiency for fog harvesters.

“…High-rise buildings have long stood as symbols of urban development, advancement, and architectural prowess. With increasing urbanization and the demand for spaces in city centers, the design and construction of such structures have become a focal point in the architectural domain (Pomaranzi et al, 2022). Among these considerations, the design of the building's façade plays a pivotal role, not only in aesthetics but also in determining the energy performance of the building.…”

In hot arid climates such as Kuwait, the challenge of heat transfer through building façades has prompted significant debate. Determining the heating and cooling loads of buildings in such environments is crucial to assess their energy efficiency. Objectives: This research was undertaken to gauge the energy efficiency of high-rise buildings outfitted with double facades in Kuwait City, emphasizing their heating and cooling loads. Methods: A parametric computer simulation was employed, utilizing the eQUEST program, to model a prototype of a high-rise building with double facades in Kuwait City. This model was used to quantify the double façade's efficacy in mitigating heating and cooling loads, drawing comparisons with typical glazing buildings in the city. Results: Findings indicate that the total energy consumption for space conditioning in buildings with DSFs was 235 MWh/year for heating and 2,890 MWh/year for cooling, aligning well with the energy conservation program (MEW/R-6/2014) benchmarks in Kuwait. Additionally, when optimally configured with materials like polycarbonate and an optimal cavity width of 50cm, DSFs contributed to a significant reduction in building loads. Specifically, the DSFs constituted 2,900 MWh/year of the total cooling load and 235 MWh/year of the heating load. Conclusion: Our results underscore the potential of double-skin façades in decreasing energy consumption for both heating and cooling purposes, demonstrating their superiority over conventional high-rise building facades in Kuwait City.
