“…PPW-7.5% and PPW-5% have the ability to reduce cooling energy consumption by 8192.44 kwh and 6327.34 kwh, respectively, with corresponding improvement rates of 22.72% and 17.50%. Considering that space cooling contributes 37–42% of a building’s total energy requirement [ 46 , 47 ], this will greatly lower the building’s energy consumption.…”

Excessive urban construction is primarily driven by uncontrolled population growth, which has serious consequences for the environment, energy, cost, and human life in general when building materials are massively used. In terms of energy and economic efficiency, buildings that make use of sustainable construction materials and technologies perform better. This is because building in an eco-friendly way results in less waste. Agro-industrial by-products and insulating materials are two examples of sustainable materials that have been put to good use in the climate change mitigation effort and to preserve the environment. Precast components are emphasized as a viable option that is suitable for this purpose and may potentially fulfill the need for housing units. Thus, this study investigated the viability of employing agricultural waste consisting of pomegranate peel waste to produce fired clay bricks. Results demonstrated that the optimum amount of pomegranate peel waste was determined to be 15%, and the optimal firing temperature was determined to be 900 °C. The thermal conductivity of all test samples was lower than that of conventional brick. Furthermore, when compared to conventional wall brick, all the tested samples of manufactured brick reduced energy consumption by 17.55% to 33.13% and carbon dioxide emissions by 7.50% to 24.50%. In addition, the economic feasibility of employing each synthetic sample was evaluated by computing the simple payback time (SPP). It was determined that 1.88–10.74 years were required for the brick samples to provide a return on their initial investment. Due to its ability to decrease heat gain, preserve energy, minimize CO2 emissions, and shorten the payback time, burned clay bricks manufactured from pomegranate peel waste are regarded as a feasible building material. Hence, manufactured bricks are usually considered an exceptional contribution to environmental sustainability.

This study investigates energy use in the construction sector and the potential for reducing energy consumption by improving the thermal efficiency of various building components, including walls, windows, roofs, and floors. The evaluation included a discussion on the prospects of reducing energy use. The building envelope is one of the most important factors to consider in terms of the heating and cooling energy efficiency of buildings. Walls are the fundamental component of a building's envelope and should provide thermal and acoustic comfort without compromising the aesthetic features of the building. The walls have a heat transfer area that is substantially higher than average, and the amount of heat gained or lost depends on the temperatures of the wall's inner and outside surface areas. Therefore, walls have a vital role in reducing the energy consumption of buildings. Bricks are a necessary component of highperformance thermal insulation, and lightweight bricks are especially useful in this regard. Bricks that are specifically manufactured for use in wall construction play an essential role in the management of energy consumption. The study has, as a result, provided a synopsis of the production of lightweight bricks in accordance with the source of the raw materials (e.g. Agriculture and industrial waste, etc).

“…Whereas the use of air conditioning equipment will significantly increase energy consumption. As a result, it would be advantageous if we could minimize our usage of air conditioning, as it is well known that global energy costs have grown [2]. Consequently, there is an urgent need to design buildings with several environmental features and characteristics that assure energy consumption decreases in these buildings [3,4].…”

The objective of this paper is to investigate how various aspects of the courtyard envelope affect the amount of energy required to maintain a comfortable temperature in Egypt's hot deserts. Two different courtyard ratios (R1 and R2) were simulated using a wide range of parameters representing the courtyard envelope's features. The parameters of two courtyards, R1 (width-to-length ratio=0.5) and R2 (width-to-length ratio=1), were studied. They included the Window-to-Wall Ratio (WWR), the surface albedo of the courtyard walls, and the orientation of the courtyard. For this study, the annual energy needed to cool an office building in New Aswan was calculated using the Design-Builder software. The results demonstrate that the courtyard envelope significantly influences the annual cooling energy demand. In addition, the efficiency of a building's cooling system improves with the increase of parameters that have a direct impact on the amount of energy required for cooling, such as WWR and surface albedo for the courtyard envelope, as opposed to those that have an indirect impact, such as courtyard proportions. More specifically, the courtyard envelope's surface albedo has the potential to reduce annual cooling energy use by more than 2.8%.
