Smart buildings have grabbed the attention of researchers since the 1980s. Until now, there has been no specific definition for smart buildings, which came from modern technologies and applications that rely on smart systems, significantly affecting the construction industry. Based on the importance of the administrative building sector in Egypt, this study proposed a general framework enumerating smart systems that positively impact this sector at the environmental, social, and economic levels (the three key pillars of sustainability). Various methods were used, including induction, descriptive, analysis, survey, and deduction. It enumerated and analyzed the Egyptian context through three case studies to reveal the gap between their current situation and the one hoped for in its three categories, Smart Security and Safety Systems, Smart Auxiliary Systems, and Smart Entertainment Systems. The findings of this study for the first category showed an average of 47% for security systems and 67% for safety systems. The category of smart auxiliary systems was divided into five sub-categories, showing 39% in climatic control systems, 60% in energy management systems, 100% in HVAC control systems, 50% in lighting control systems, and 56% in water management systems. Finally, the smart entertainment systems category was divided into three sub-categories, showing 42% in Wi-Fi and Internet systems, 44% in video surveillance systems, and 67% in sound and video intercom systems. Therefore, these quantitative findings represent promising results that motivate the Egyptian context to move forward in this direction by using smart systems to improve the sustainability of Egyptian administrative buildings.

Most people use stairs during emergencies and evacuations. Therefore, this study addressed the impact of staircase rotation to minimize physical effort and evacuation time, hypothesizing that staircase rotation affects the evacuation speed and the safety of the occupants. This study consisted of two stages. In the first stage, a questionnaire was delivered to architects, with two key questions about the preferred direction in daily use and the other regarding evacuation cases. The second stage involved field experiments on two different staircases in the rotational direction, which were applied to 53 participants to measure the efficiency of the staircases in four cases (slow descent, slow ascent, fast descent and fast ascent). The counter-clockwise staircase during the field experiments showed better results and was more efficient. The heart pulse rate (pulse/min) in the clockwise case showed a clear increase compared to the counter-clockwise case by 12.89% for slow descending, 6.91% for fast descending, 21.51% for slow ascending, and 18.27% for fast ascending. Therefore, the theoretical and practical results of the study validated the hypothesis on the impact of the staircase rotation on user comfort and evacuation speed. Moreover, it was concluded that counter-clockwise staircases provided faster evacuation with less physical effort.

“…Despite the significance of date palms, research exploring the conversion of date kernel residues into activated carbon remains scarce (Al-Fahdawi, 2019). Similarly, koura clay, commonly utilized in brick-making, presents variability in mineral composition based on geographical origin, influencing the properties of resulting bricks (Dill 2016;Konbr, Freewan, and Alshuk 2016).…”

“…At initial concentrations of 150 mg/L, shaking was required for approximately three hours to achieve most of the maximum pollutant removal. The pollutant adsorption increased with increasing contact time and remained constant for 30 minutes after reaching equilibrium for different starting concentrations(Konbr, Freewan, and Alshuk 2016) (Suresh, Sugumar, and Maiyalagan 2011). The empty holes on the surface cause the initial high rate of absorption.…”

We used activated carbon derived from Iraqi date cores to study the efficacious removal of acetamiprid pesticide effluent. This activated carbon was made using chemicals and physical processes involving a 5M hosphoric acid solution. Various factors such as the concentration of acetamiprid pesticide, mixing duration, contact time, the quantity of activated carbon, temperature, and pH of the media were examined to understand how they influence the efficiency of acetamiprid pesticide removal. The results show that maximum adsorption of 0.05 g/L dosage, 150 mg/L dye concentration, and 3-hour contact time adsorption duration were optimal for 97.00- 99.00% removal efficiency. The adsorption equilibrium was performed using Freundlich, Temkin, Harkins-jura, Dupin, Elovitch, and Langmuir. Density function theory (DFT) was used to simulate the pesticide acetamiprid to determine the reaction origin. The results show that the Freundlich model with R2 values equal to 0.738 demonstrated better agreement with the adsorption experimental data. According to thermodynamic analysis, the pesticide is endothermic and spontaneous, indicating increased unpredictability at the adsorbent-adsorbent interface. It also indicates the pHZpc of the negatively charged carbon surface at pH = 2.0. Two models of pseudo-first and pseudo-second order were included in the kinetic analysis. The outcomes indicate that a pseudo-second-order model with R2 > 0.9998 fits the experimental data better.
