As a result, the success of a plaza depends on a variety of elements, including its design, security, appealing façade, and amenities. This study examined the structural systems, services, and architectural designs of a few of Lahore's prosperous plazas. Food courts and hyper malls provide essential functions that boost foot traffic and have the potential to revolutionise the way that entertainment amenities raise a mall's worth. Mixeduse multi-story spaces such as those that combine offices, apartments, and retail stores can also increase the efficiency of a mall in terms of sales and attractiveness. The assessment parameters in case studies include the gross area, circulation, parking area, toilet area, services area, and vertical transportation, with average values of 33,83 %, 22,00 %, 24,30 %,1,10 %, 3,05 %, and 4,60 %, respectively. These will assist future studies to determine the minimum threshold for success, making mall planning easier and more accurate. High-quality malls have higher occupancy because they offer better quality development, facilities, sustainable techniques, and amenities to support the overall development, along with shop sizes that suit international brands. This research defines the emerging trends and provides guidelines for the future architectural planning, structural systems, and services of shopping malls in Lahore to meet sustainable development goals and attract more shoppers.

Addressing water scarcity and protecting accessible water sources necessitates the effective treatment of wastewater. This makes the use of sustainable solutions such as constructed wetlands (CWs) essential. CWs leverage natural processes involving wetland vegetation, soils, and microbial communities. This study evaluates the efficiency of a horizontal sub-surface flow CW, established with local plants at Hudiara drain, in removing pollutants such as Biochemical Oxygen Demand (BOD), Turbidity, Nitrates, Phosphates, and pH, across different months. The study reveals that while temperature and precipitation rates influence the CW's efficacy, the linear regression model indicates a strong correlation between phosphorus and BOD levels with precipitation. However, nitrates are sensitive to temperature, and turbidity is influenced by both temperature and precipitation within certain limits. Additional factors impacting CW performance include wastewater characteristics, design flow, and wetland location. When compared with Pakistan Environmental Quality Standards (PEQS), it is concluded that CWs are effective in wastewater treatment. By constructing CWs along the banks of wastewater drains, treated water from the outlet chamber can be collected and redirected, offering a viable solution to water scarcity challenges.

Thus, removing F-from drinking water is pivotal for preventing serious health consequences. The WHO recommends a limit of 1,5 mg/L for fluoride in drinking. Excessive amounts of fluoride in drinking water are prevalent in Pakistan, leading to related health risks. Low-cost techniques for the defluoridation of drinking water can be used. In this study, the removal of fluoride from drinking water by an adsorption method using lowcost materials/adsorbents, such as marble chips, wheat husks, rice husks, egg shells, concrete, fuller earth, fly ash, freshly fired bricks, and charcoal, at different contact times and different bed thicknesses was investigated. A batch sampling technique was used for sample collection. On average, marble chips, wheat husks, rice husks, egg shells, concrete, fuller earth, fly ash, freshly fired bricks, and activated charcoal (rice husk) resulted in 71,99 %; 90,99 %; 66,73 %; 90,99 %; 63,30 %; 71,99 %; 22,60 %; 49,67 %; and 90,13 % fluoride removal, respectively. Therefore, defluoridation using these materials is desirable. The performance of adsorbents depends on parameters such as contact time, depth of the adsorbent media, and pH. The bed thickness of the adsorbent has a minor effect on fluoride removal. The major contributors to fluoride removal from water are contact time and adsorbent composition.
