This case study explores strategies for reducing energy and water consumption in apartment buildings, focusing on sustainable and eco-friendly practices. The research examines a specific apartment complex, analyzing current usage patterns and identifying areas where efficiencies can be made. Key aspects of the study include assessing energy consumption through heating, cooling, lighting, and electrical appliances, alongside water usage for daily activities such as washing, bathing, and landscaping. Various energy-saving and water-conserving technologies, such as energy-efficient appliances, water-saving fixtures, and renewable energy sources, were introduced and evaluated for their impact on overall consumption. The study also considers the role of resident behavior and education in promoting eco-friendly practices. Results show a significant reduction in both energy and water consumption, leading to lower utility costs and a smaller environmental footprint. The findings provide actionable insights for apartment managers, developers, and residents seeking to adopt sustainable living practices, ultimately contributing to more resource-efficient urban living environments.
