Evaluating the Performance and Prospects of Green Buildings in Bangladesh: A Case Study Approach

Green building encompasses sustainable construction methods that reduce waste and energy consumption while integrating environmentally friendly practices, considering their impact on nature and human health. These buildings are designed and constructed to offer safe, healthy, and sustainable living spaces. They improve indoor air quality, conserve energy and water, preserve their value over time, and prioritize materials that promote health and resilience. In today's world, the demand for sustainable building practices has surged significantly. Developed countries aim to become leaders in green building, while in developing nations like Bangladesh, although adoption remains low, interest is steadily rising. Few studies have yet been conducted on green building practices in Bangladesh. This paper offers a critical review of existing research on green buildings in Bangladesh, identifying common themes and methodologies. Major topics include defining green buildings, comparing their benefits with conventional buildings, and exploring ways to achieve them. Using available data, this study also presents a case study of Karupannya Rangpur Ltd., regarded as one of Bangladesh's top green factories. Its LEED (Leadership in Energy and Environmental Design) rating is in the platinum category with a score of 71. The average internal and external temperature difference at this site was 4.33°C, compared to 1.67°C for a conventional building under similar conditions. Opinions from representatives about the prospects and overview of green buildings in Bangladesh were collected, along with data on temperature control and energy use. The findings of this research will be valuable for people interested in green building practices and may guide future researchers, builders, and environmental specialists working in similar geographic areas.
