“…The opaque part of the building envelopes consists of layers of building materials, and the improvement in the physical and optical properties (reducing thermal conductivity values and increasing the solar reflection coefficient) of building materials is necessary to achieve energy efficiency in buildings in hot climate regions. A simulation was made using the Designbuilder program [15] to compare the performances of the base case (traditional finishes for exposed walls and ceilings) and the newly developed material when applied to an administrative building with dimensions of 4 x 6 m. in the city of Cairo. As shown in Fig.…”

Waste materials are deemed an environmental burden; although, they can be recycled in the production of sustainable building materials. The aim of this study is to develop an aesthetic architectural rendering green mortar with utilizing recycled waste colored glass as supplementary fine aggregate. Limestone Calcined Clay Cement (LC3) has been prepared as a green and sustainable binder by replacing 60 wt% of white Portland cement () with a blend of limestone (LS) powder and metakaolin (MK) with a LS: MK of 1:2 (wt%). LC3-based mortars were prepared in which the binder was combined with expanded polystyrene beads (EPS) as fine aggregate with aggregate volume content of 75%. EPS was partially replaced with recycled waste glass (RWG) at various percentages of 10, 20, and 30 vol.%. Bulk density, thermal conductivity, solar reflectivity and flexural strength of the hardened mortars were determined after 7days of curing. The contribution of the newly developed mortars into reducing internal thermal loads and energy use has been evaluated for administrative/ office building in EGYPT. The mortars incorporating 10 and 20vol.% of RWG possessed thermal conductivity values in the range of thermal insulation rendering mortars. The incorporation of RWG led to enhanced solar reflectivity, an increase by about 77% has been achieved relative to the traditional one coat - rendering mortar; in addition, the newly developed rendering mortar provided a reduction in electric cooling energy annual consumption by about 30%

“…For instance, the cement block appears uneven because of the large amount of agricultural waste on its surface. Buildings constructed from cement blocks containing coconut husk, vermiculite, and sugarcane bagasse would have an ugly appearance and applying joint mortar and surface plaster would be challenging (Seddik Hassan et al, 2022).…”

Agricultural waste can be used in cement block production for a number of reasons, including its environmental, economic, and labor benefits. This study examines the mechanical, durability, and cost-effectiveness characteristics of cement blocks. A cement block made from agriculture waste promotes sustainable construction practices, since waste agriculture is often dumped in landfills and regarded as a waste material. Carbon dioxide (CO2) emissions produced by the construction sector, either from the firing of clay bricks or from the production of cement, contribute significantly to global warming. In many developing countries, air pollution from agricultural activities is primarily accounted for the emissions from agricultural machinery and openly burning agro-waste. Farming is one of the leading causes of water and soil pollution. Hence, adopting agricultural waste into cement production would significantly reduce the environmental impact of concrete structures. The goal of this research is to determine whether agricultural waste products, such as vermiculite, pistachio shells, sugarcane bagasse, and coconut husks, can be used to substitute sand in concrete blocks. The water absorption capacity of waste materials, density, flexural strength, fire resistance, and compressive strength of waste materials as admixtures in concrete were evaluated using experimental tests. In most cases, the concrete blocks made from agricultural waste were strong enough to satisfy ASTM standards. The specimens containing coconut husks and pistachio shells, among others, were found to be fairly strong and durable, even when isolating them from water.

“…High importance was accorded to fire performance sub-criteria, and this result can be explained because of evacuation-related risks during fire situations [149]. A building fire can result in human casualties and facilitate the spread of fire through damaged walls or to neighboring compartments or buildings [150].…”

Material selection in buildings profoundly affects project success, encompassing durability, maintenance, customer satisfaction, production systems, lifecycle, usage, environment, and costs. Yet, there is a need for further research on indicators for choosing materials in prefabricated buildings. Therefore, this study’s main objective was to identify the indicators (criteria and sub-criteria) for selecting materials for prefabricated wooden construction and, subsequently, categorize these criteria and sub-criteria based on the perspective of industry professionals. To achieve this goal, three phases were carried out. First, a literature review was conducted to identify potential criteria for choosing structural and envelope materials in wooden prefabricated buildings. Second, a pilot survey was conducted in Canada and the United States to classify the priority order of the criteria obtained from the literature based on professionals’ opinions. Finally, Monte Carlo simulations were conducted with different iterations (1000, 10,000, and 100,000) using the data obtained from the previous phase to improve decision-making and classification processes. For the indicators to select materials, the literature review identified seven main criteria: performance properties, green materials, energy efficiency, circular economy, site conditions and material logistics, standards, and social impact. These criteria contained a total of 25 sub-criteria. The pilot survey data analysis demonstrated that the performance properties, site conditions and material logistics, and social impact criteria were consistently prioritized. The critical sub-criteria identified were fire resistance, watertightness, local availability, occupant health, and safety and protection. For the Monte Calo simulations, the predictions aligned with the pilot study, enhancing the robustness of the results.
