Improving the adhesion of satin XPS to sandstone with customized polyurethane adhesives for sustainable facade cladding and thermal insulation

Six PU adhesives were synthesised with two different polyols (PPG and PEG based) of three molecular weights, namely 400, 1000 and 2000 g mol−1, and MDI, to prepare sandstone-XPS isolating façade panels. The chemical structure, thermal properties, and adhesion properties in the preparation of the panels were evaluated. Both sandstone and XPS are commonly used materials in construction due to their excellent insulating properties, durability, flexibility, water resistance, and aesthetic appeal, making them environmentally attractive. The industry trend is towards using sanded XPS in these panels, as better adhesion is achieved with typical adhesives compared to satin or unsanded XPS. However, this entails waste generation from sanding, a higher panel price and a difference in adhesive consumption from 309 g m−2 to 684 g m−2 for unsanded (or satin) and sanded XPS, respectively. In this study, all prepared panels exhibit good adhesion properties, even those made with satin XPS. Panels prepared from PPG-based adhesives show better adhesion performance than those made from PEG, reaching 0.52 ± 0.07 N mm−2 with the 1000 g mol−1 PPG polyol-based adhesive. These highest adhesion properties are due to the optimal balance of flexible and rigid segments in the polymer material structure. The adhesive maintains its high performance even after harsh temperature and humidity conditions. After accelerated ageing with heat, cold and water, the probes retain between 65 and 71 % of the original tensile strength (0.34 ± 0.03, 0.35 ± 0.07 and 0.37 ± 0.01 N mm−2, respectively). This finding suggests an interesting starting point for cost savings associated with sanding and reduction in XPS waste generation, making them economically and environmentally appealing.

Alternative material recommendation for facade cladding: High silica-containing stonepaste ceramics

This study investigated the potential of using stonepaste ceramics, which were widely preferred as a coating and decoration material on the facades of architectural buildings in ancient times and continues to be produced on a workshop scale today as a cladding material on building facades. Stonepaste ceramics, made from a mixture prepared with a high amount of crystalline quartz as well as frit, plastic clay, and bentonite raw materials, were hand-shaped and sintered at 930 °C after glazing. The physico-mechanical properties of stonepaste ceramics, their behaviour under various environmental conditions (resistance to chemicals, frost, and thermal shock), and their microstructures have been characterized. The characterization results were compared with the properties of commonly used facade cladding materials. It was determined that stonepaste ceramics had a very low firing shrinkage value (2.84 %) compared to that of other ceramic cladding materials, a higher water absorption value (11.79 %) than that of porcelain tiles and floor tiles, and close to wall tiles, and a flexural strength value (33.64MPa) higher than wall tiles and close to porcelain tiles despite the high-water absorption value. Ten cycles of thermal shock resistance showed that the body and glaze layer of the stonepaste ceramic material are well bonded to each other, and there is no significant thermal expansion mismatch between them. One hundred cycles of freeze-thaw conditions indicated that the stonepaste ceramic had good adhesion and thermal expansion compatibility between the glaze and the body but only chipping damage under the action of tensile forces caused by the freezing of water entering the pores of the body. In terms of behaviour against various chemicals, stonepaste ceramics were found to be highly resistant to high and low concentrations of household chemicals, swimming pool salts, and alkalis but less resistant to low concentrations of HCl and citric acid and high concentrations of HCl and lactic acid compared to other chemicals. The results show that stonepaste ceramics, despite their high-water absorption potential, have properties close to those of traditional ceramic tiles and, like these materials, can serve for significant periods in various environmental conditions when used as facade cladding. Consequently, it has been revealed that stonepaste ceramics can be used as a facade cladding material in sustainable, long-lasting, contemporary architectural facades thanks to their technical and protective properties.

Assessment of Damages in Precast Industrial Buildings in the Aftermath of Pazarcık and Elbistan Earthquakes

ABSTRACT Two major earthquakes with moment magnitudes of 7.7 and 7.6 struck the districts of Pazarcık and Elbistan, causing thousands of deaths and severe damage. A lot of buildings located in 11 different cities were damaged or collapsed. In addition to urban areas, industrial regions were also affected and damaged by these earthquakes. In this study, the results of assessment studies performed in the industrial zones located in Malatya, Adıyaman, Kahramanmaras, Osmaniye, and Hatay cities are presented. The maximum seismic demands instrumented by the strong ground motion stations were first investigated. Then, the acceleration records obtained from the stations near the visited industrial zones were studied, and the spectral demands were compared to the code spectra. Obtained results have revealed that spectral acceleration and displacement demands are higher than that of design earthquake in many stations. Even in some stations, it was determined that the spectral demands, especially in the constant velocity region where the periods of precast industrial buildings are located, also exceeded the demand of the maximum earthquake of the code. After demand assessment studies, the structural properties of existing precast buildings are presented, and the reasons behind the damages are discussed. Site inspections have shown that connection failures are the most common type of damage observed. The overturning of roof girders and shear damage at corbels and beam ends are the typical forms of joint failures. Column flexural failures and other factors that cause the structural damage are discussed and explained. Non-structural damage was also determined in many buildings. Damage to suspended ceilings, facade cladding, products and equipment, and partition walls are the typical examples of non-structural damage observed. Reconnaissance studies have shown that the damaged building ratio in Kahramanmaras Turkoglu and Adıyaman Petrol industrial zones is significantly higher than in other regions visited. Damage distributions in Kahramanmaras Turkoglu and Adıyaman Petrol industrial zones, where comprehensive information was gathered, are presented and evaluated.

The possibility of application of bonded joints on different facade systems

Bonded joints in the construction industry have a rich history dating back to ancient civilisations, where they were mainly used to join materials such as wood or stone. In particular, natural materials such as bitumen or natural resins were used for this purpose. In the present modern era, with the development of adhesive technologies and synthetic adhesives, they have become an essential part of construction industry practice. Within facade cladding, bonded joints are becoming key to achieving high thermal insulation performance and overall building energy efficiency. The correct design of the building envelope is increasingly relevant in the context of the geopolitical situation starting with the global pandemic COVID-19 and the two conflicts between Russia and Ukraine and between Israel and Palestine that resulted in energy crises [1]. The paper summarizes the potential applications of adhesive bonded joints on facades, the types of adhesives used at different joints and their ability to provide strong and durable joints when exposed to different climatic conditions during summer and winter months.

Experimental and numerical study of fatigue life for Aluminum Composite Panel (ACP) under the ranges of wind speed effect

ABSTRACT The aluminium composite panel ACP is used as an outer decoration for building facade cladding. In general, these frontal faces of buildings are exposed to weather conditions, like (temperature, rain, wind speed, etc.). The aim of present research is investigating the wind speed influence upon the fatigue life for the ACP under a range of wind speeds varying between (4 m/s) and to (17 m/s). The mechanical properties of ACP were measured by tensile and fatigue tests. Three specimens of the tensile test were fabricated according to standard dimensions. The bending stress was applied as amplitude load, and the number of cycles to failure was recorded and plotted in the (S-N) curve. The fatigue limit was detected according to the number of cycles (106). Three models of the ACP material were simulated, using the software ANSYS version 15 at different areas (0.8, 1, and 1.2 m2), and a safety factor was detected that was generated by the fatigue load. The results manifested that the fatigue limit of the ACP material is around 2.3 MPa. The outcomes elucidated that the decrease in applied load leads to an increase in the number of cycles to failure owing to the fatigue load. On the other hand, the safe wind speed is (14.8 m/s) for the (0.8 m2) area, while (13 m/s) and (11 m/s) can be safe in the design for the areas (1 m2) and (1.2 m2), respectively. The commercial (ACP) can be used as an external decoration in Baghdad city in any tested area if the wind speed does not exceed 11 m/s due to its ability to carry out the atmospheric conditions

Solving Separation Distances from Flammable Surfaces of Exterior Walls by Central-European Standards

The paper deals with the topic of determining the density of heat flow from combustible surface treatments of exterior walls, such as combustible insulation systems, combustible cladding of facades and from all-wood constructions of exterior walls. Heat flow density is an important indicator in determining the fire resistance rating of exterior walls and in determining safe separation distances. The article describes the ways in which exterior walls can be classified in terms of fire resistance. One of these methods is a numerical calculation (of the surface amount of released heat and heat flow density), which will be applied to various types of combustible surfaces of the perimeter walls of wooden buildings. The results showed that the numerical calculation is a suitable method for determining the classification of fire resistance rating of exterior walls with combustible coating. The Czech legislation defines the criteria for this classification better.

Influence of Fire Exposition of Fibre-Cement Boards on Their Microstructure.

The diagnostics of materials, elements and structures after fire exposure are very complicated. Researchers carrying out such diagnostics encounter difficulties at the very beginning, e.g., how to map fire conditions. In this publication, the authors focused on the analysis of the fibre-cement composite used as facade cladding. The fibre-cement boards are construction products used in civil engineering. The fibre-cement boards are characterised by two phases: the matrix phase and the dispersed phase. The analysis of fibre-cement composite was performed using non-destructive methods. The use of non-destructive methods in the future will allow for the analysis of facades after fires without the need to obtain large elements, which will significantly reduce costs while increasing safety. The aim of the work was to determine internal changes in the microstructure of fibre-cement boards after exposure to fire. The degraded samples were compared with reference samples in the evaluation of the microstructure. An analysis was performed using a scanning electron microscope, images of backscattered electrons (BSE) and maps obtained using Energy Dispersive X-ray Spectroscopy (EDX), which allowed conclusions to be drawn. The observed changes were presented in the form of photos showing changes in the composition of the plates, and they were commented on. It should be noted that fire temperatures act destructively, and a number of changes can be observed in the microstructure. The results of the work indicate that, in the future, the use of non-destructive methods will make it possible to assess the degree of degradation of the façade after a fire.

Influence and effectiveness of horizontal diaphragms and cladding wall panels on the seismic behaviour of precast RC industrial buildings

The seismic behaviour of precast reinforced concrete industrial structures has been extensively investigated in recent decades, especially after the damage caused by recent earthquakes. The interaction of the roof's horizontal diaphragm with the structural and non-structural elements can influence the seismic behaviour of these buildings. Thus, the present study aims to investigate this interaction, through nonlinear static and dynamic analyses using a simplified macro element to simulate the behaviour of cladding panels and an equivalent truss approach to simulate the roof in-plane stiffness. The analyses were performed on several structural models considering the current European single-storey precast reinforce concrete industrial building stock, with or without cladding wall panels, and with rigid or flexible diaphragm roof. Despite the uncertainties associated with the ability of common roof systems to ensure a rigid diaphragm, the analyses allowed the establishment of a correlation between the buildings generic properties and the roof horizontal stiffness required to approach a rigid diaphragm effect. In general, the results show that the consideration of a rigid diaphragm in numerical models may tend to produce a more realistic seismic behaviour of the overall structure. Furthermore, the contribution of facade cladding wall panels significantly influences the seismic behaviour of the building, especially for high-rise buildings.

Experimental investigation of engineering properties of silica sand filled mortars containing high doses of SWCNT

Recently, great efforts have been made by researchers on the mixture of electrically conductive concretes that have been developed for different purposes. In this study, an experimental research was carried out on electrically conductive mortar mixtures especially for shell elements produced for building facade cladding. Six different mixtures were produced, including the non-conductive reference mixture. Single-walled carbon nanotube (SWCNT) was used as nano-sized conductive additive material. SWCNT was added at 0.2% and 0.3% of cement weight. SF was added to the same mixtures as another group at the rate of 4% by total weight. 2, 14, 28, 90 and 180 days electrical resistivities of the obtained conductive mortar samples were measured. As a non-destructive method, dynamic resonance testing was performed and the 28-day damping rates of the samples were determined. Ultrasonic pulse velocity (UPV) and Leeb hardness tests were performed, respectively, by using other non-destructive testing methods to obtain information about the internal structure voids and surface hardness of the samples. SWCNT, which causes low machinability and therefore internal structure voids, caused a decrease in compressive strength and flexural strength, as well as a significant increase in electrical conductivity.

Development of Photocatalytically Active Anodized Layers by a Modified Phosphoric Acid Anodizing Process for Air Purification

One of the key urban air quality issues is pollution by nitrogen oxides (NOx). To reduce NOx, facade cladding could be provided with photocatalytic properties by incorporating titanium dioxide nanoparticles. For this purpose, a modified phosphoric acid anodizing process (MPAA) was developed for the facade alloy EN AW-5005, in which highly ordered anodized structures with a low degree of arborization and tortuosity were produced. Pore widths between 70 nm and 150 nm and layer thicknesses of about 2–3 μm were obtained. The subsequent impregnation was carried out by dip coating from water-based systems. Depending on the dip-coating parameters and the suspension used, the pores can be filled up to 60% with the TiO2 nanoparticles. Photocatalytic tests according to ISO 22197-1 certify a high photocatalytic activity was obtained with rPCE values > 8 and with rPCE > 2, achieving “photocatalytically active for air purification”. Tests on the corrosion resistance of the anodized coatings with a commercially available aluminum and facade cleaner confirm a protective effect of the anodized coatings when compared with nonanodized aluminum material, as well as with compacted anodized layers.

Sustainable façade cladding selection for buildings in hot climates based on thermal performance and energy consumption

Façade cladding system is essential contributor to the sustainable performance of buildings. Holistic investigation of building facade cladding performance with respect to the regional microclimate is paramount and can contribute to an under investigated research area. The research aims at analyzing the different building facade cladding systems and developing sustainable design guidelines for selecting efficient facade cladding system in hot climates. To achieve this goal, the multi-criteria method of order of preference by similarity to ideal solution is utilized to evaluate experts’ preference of façade cladding according to essential selection criteria, and an integrated environmental solutions-virtual environment simulation technique is applied to analyze thermal performance of the different cladding systems. The findings indicate that stone system is the most preferable cladding material with the highest relative closeness compared to the aluminum composite panel and plaster systems. The recommended façade system is the stone cladding which can reduce the cooling load by 4% and 1.5% compared to the aluminum panel and plaster systems, respectively. Simultaneously, it is found that polyurethane board material reduces the cooling load by 3.8% compared to sandstone with expanded polystyrene. Fire risk ranked at the top of the selection sub-criterion. The simulation demonstrates that fire risk related to the aluminum panel system can be alleviated by using high ignition point insulation materials such as mineral fiberglass and glass wool. Therefore, gravel gray stone cladding system with a cavity and mineral fiberglass is recommended in hot climates for its superior thermal performance and fire resistance.

Experimental characterization of comfort performance parameters and multi-criteria sustainability assessment of recycled textile-reinforced cement facade cladding

Within the building construction sector, fiber cement boards have attracted interest as facade cladding materials in the last ten years, especially those that incorporate –for reinforcing purposes– natural and/or recycled synthetic fibers (i.e, from the textile industry). So far, the design-governing parameters of facade cladding panels have been mechanical strength, durability, constructability, aesthetics, insulation capacity, and fire resistance. From the sustainability perspective, the impact of the facade on the economic and energy efficiency performance is most often the parameter that leads the decision-making process. Within this context, the quantification of the sustainability performance of the facade –accounting for economic, environmental, and social indicators– is unfrequently carried out in design and project phases, this being attributed to the lack of methodologies that allow considering and quantifying some relevant indicators representative of the facade sustainability performance. As consequence, decisions made based on solely economic and on some of the environmental indicators might lead to solutions with lower sustainability performance than that required (or expected). Recycled textile waste fabric-reinforced cement board as a facade-cladding material for building envelopes is the focus of this research. In order to characterize the fire resistance, and thermal and acoustic insulation –as relevant serviceability parameters– of this material, an experimental program was carried out. Likewise, the sustainability performance of this facade-cladding is assessed through a method based on the Integrated Value Model for Sustainability Assessment (MIVES). This multi-criteria decision making (MCDM) model relies on the value function concept and the multi-disciplinary participation of experts to identify and quantify the relevant indicators of the facade sustainability performance and the relative importance of indicators and requirements. The MIVES-based model generated for this research can be straightforwardly used for assessing the sustainability performance of facade-cladding techniques made of any material and for any type of building (and location). The application of the MIVES model led to the sustainability index of this new material for facade-cladding ranging from 0.68 to 0.71 (/1.00) for different weighting scenarios.

Противопожарные расстояния от наземных автостоянок до жилых зданий

Проанализированы нормативные требования к противопожарным разрывам от жилых зданий до границ открытых автостоянок. Рассмотрены особенности горения легковых автомобилей. На основе полевого моделирования изучены особенности распространения опасных факторов пожара (ОФП) и их воздействие на жилые здания при одновременном горении двух автомобилей. Моделирование проводилось при различных расстояниях до автостоянок и с учетом воздействия ветровой нагрузки. Показано, что на расстоянии от жилых зданий до автостоянок менее 10 м может потребоваться устройство огнестойких наружных стен здания с противопожарной защитой оконных проемов и применением негорючей облицовки фасада. The problem of parking lots and parking spaces is relevant in many large cities, which leads to the need to optimize parking space. The analysis of the regulatory framework in the field of fire safety of open parking lots has shown that the values of quenching distances from residential buildings to the boundaries of parking lots are associated with the fire hazard of the building, its number of storeys, fire resistance limits and characteristics of load-bearing and enclosing structures. In accordance with the new regulatory requirements, quenching distances from open storage areas, car parking to buildings and structures are not normalized. At the same time, when developing fire-fighting measures, it is necessary to take into account that the intensity of the fire impact on the building can significantly increase, for example, with the simultaneous ignition of two or more cars in the event of fuel spills, as well as arson. The purpose of this research is to study the peculiarities of fire hazards spread during simultaneous ignition of two or more cars on the basis of field modeling and to assess the possibility of fire-safe placement of an open parking lot in residential areas. To achieve the purpose of the study, field (CFD) modeling of fire dynamics using the FDS computer program was used. When modeling, calculations of fire hazards spread from an open parking lot and their impact on a residential building were carried out. As a result of modeling the fire development, temperature distributions, smoke and heat flows were obtained at different points in time at the window openings of a residential building at different points in time. The simulation was carried out at different distances and taking into account the impact of wind load. The results of the study showed that with the simultaneous ignition of two cars, the value of quenching distance of 10 m to open parking lots provides a condition for non-proliferation of fire on a residential building. With a decrease in the distance of less than 10 m, the values of the heat flux density and temperature at the window openings of apartments in the lower floors of the building under the influence of wind load may exceed critical values. In the residential areas of the lower floors, there may also be an excess of the values of fire hazards. To exclude this effect it is necessary to install fire-resistant exterior walls of the building with fire protection of window openings, as well as the use of finishes, facade cladding made of non-combustible materials. The simulation also showed that for residential buildings with a stylobate with a width of at least 5 m, quenching distances may not be observed when applying appropriate fire protection to the exterior walls and openings of the stylobate.

Mathematical models to assessment the energy performance of textured cladding for facades

ABSTRACT The temperature increase of a city in relation to its peripheral areas leads to the formation of an Urban Heat Island. Working on the opto-thermal properties of the building envelope is a viable mitigation strategy to reduce the temperatures of a city. Having quantitative data on energy performance allows the development of precise evaluations and the selection of the most efficient data in relation to energy consumption. The degree of efficiency of a material is calculated with an indicator called Solar Reflectance Index (SRI). Since opto-thermal properties change over time, the standard recommends obtaining the SRI level of both new and three-year-aged material (SRI3). In the present work, 80 facade claddings were evaluated to: (a) determine which qualitative variables significantly influence the SRI3 of the claddings; (b) obtain an equation that calculates the SRI3 without the need to monitor the large number of variables used for its calculation. For this, the following statistical methods were used: multifactorial ANOVA and linear regression model. In this correlational analysis, color, composition and texture were selected as independent variables. The research showed that color is the variable that significantly influences SRI3 in all the evaluated claddings. By means of the equation obtained with the regression model, the SRI3 index was predicted reaching 95% IC. These results significantly save time and simplify the process of obtaining data since it is not necessary to monitor numerous input variables to calculate the indicator.

A Textile Waste Fiber-Reinforced Cement Composite: Comparison between Short Random Fiber and Textile Reinforcement.

Currently, millions of tons of textile waste from the garment and textile industries are generated worldwide each year. As a promising option in terms of sustainability, textile waste fibers could be used as internal reinforcement of cement-based composites by enhancing ductility and decreasing crack propagation. To this end, two extensive experimental programs were carried out, involving the use of either fractions of short random fibers at 6–10% by weight or nonwoven fabrics in 3–7 laminate layers in the textile waste-reinforcement of cement, and the mechanical and durability properties of the resulting composites were characterized. Flexural resistance in pre- and post-crack, toughness, and stiffness of the resulting composites were assessed in addition to unrestrained drying shrinkage testing. The results obtained from those programs were analyzed and compared to identify the optimal composite and potential applications. Based on the results of experimental analysis, the feasibility of using this textile waste composite as a potential construction material in nonstructural concrete structures such as facade cladding, raised floors, and pavements was confirmed. The optimal composite was proven to be the one reinforced with six layers of nonwoven fabric, with a flexural strength of 15.5 MPa and a toughness of 9.7 kJ/m2.

Обеспечение безопасности на строительной площадке. Методика статического испытания шва из минеральной ваты на продавливание между плитой перекрытия и фасадом здания на этапе «строительства»

The article presents the main provisions of ensuring safety on the construction site. Safety of the joint (at the construction stage) between the ceiling plate and the facade cladding sealed with the mineral wool (stone wool) and a firestop sealant is considered. A seam that has not yet been sealed presents a potential hazard of injury or falling objects to a lower level that requires actions within the standard procedures. When a seam is sealed, its hazard becomes less obvious. The purpose of this work is to assess the safety of the described design. For this purpose, a test setup, a method for testing a seal for static strength were developed, the tests were carried out with subsequent analysis and conclusions. The object of study is a seal (at the construction stage) between a reinforced concrete slab and a facade finishing element filled with a mineral wool and covered with a highly elastic refractory sealant. The testable criterion for the performance of the joint is its ability to withstand the load of a person. As a possible further continuation of this work, the first aspect that needs to be studied is the testing of a building element of a similar design during its operation phase, when the joint is covered with a reinforced screed with a thickness of 50 mm. The second important aspect is that the performance criterion should be extended to the fall of a rigid object from a height, and the appropriate tests should be carried out. The third important aspect is the need to develop test methods, in which the joint will be subjected to dynamic impact, since if the resistance of the joint to foot penetration or to objects falling from a height is considered, the load will not have a slow, static nature.

The Factors Causing Height-Fall Accidents Occurring During Roofing and Facing Works

In order to take the necessary safety measures and to minimize the risk of accidents that may occur during the production, dismantling, and repair of roof and facade cladding systems, during the design process, it is necessary to analyze the prominent accident types and their causes with numerical data. In this study, concerning construction sector, the principal factors affecting fall accidents occurring during roofing and facing works are investigated by a questionnaire survey. Exploratory Factor Analysis (EFA) is utilized to analyze the survey results. The results of the EFA identify three key factors; (1) business culture and inappropriate workplace, (2) dynamic and unstable external effects, and (3) job analysis. As a result of this study, the main factors affecting the accidents of falling from height during roofing and facing works are identified and contribution is made to the selection of appropriate protection methods for the practitioners.

Reduction of Load Capacity of Fiber Cement Board Facade Cladding under the Influence of Fire.

The paper analyzes the issue of the reduction of load capacity in fiber cement board during a fire. Fiber cement boards were put under the influence of fire by using a large-scale facade model. Such a model is a reliable source of knowledge about the behavior of facade cladding and the way fire spreads. One technical solution for external walls—a ventilated facade—is gaining popularity and is used more and more often. However, the problem of the destruction during a fire of a range of different materials used in external facade cladding is insufficiently recognized. For this study, the authors used fiber cement boards as the facade cladding. Fiber cement boards are fiber-reinforced composite materials, mainly used for facade cladding, but also used as roof cladding, drywall, drywall ceiling and floorboards. This paper analyzes the effect of fire temperatures on facade cladding using a large-scale facade model. Samples were taken from external facade cladding materials that were mounted on the model at specific locations above the combustion chamber. Subsequently, three-point bending flexural tests were performed and the effects of temperature and the integrals of temperature and time functions on the samples were evaluated. The three-point bending flexural test was chosen because it is a universal method for assessing fiber cement boards, cited in Standard EN 12467. It also allows easy reference to results in other literature.

MATERIAL DESTROYED ACCORDING TO LIGHT EXPOSURE TIMES IN ARCHITECTURAL EXTERIOR COVERINGS

Facades, which are the faces of buildings and cities, are the elements that affect the city and the user with their designs. However, facade coatings do not remain as new as the first day they were made. The first important parameter here is the type of quality material used. Because light interactions occur due to the internal structure of the materials used in the facade cladding. The resistance of materials to daylight differs in terms of illumination level and duration. In international standards, there is a categorization as insensitive, less sensitive, moderately sensitive, and very sensitive materials. This study analyzed discoloration and physical variation in daylight for some of these materials. Accordingly, dark wood, light wood, paint, etc. A simulation program was used to measure the damage caused by exposure to light on the facade cladding of some materials. The color fading effect of light is due to parameters such as the continuity of the light and the high level of daylight. In the selection of materials used for facade cladding, stone, metal, composite metals and UV-resistant paint types that are insensitive to light or less sensitive should be used.
