Evaluating the performance and prospects of green buildings in Bangladesh: a case study approach
摘要
Green building promotes sustainable construction methods that reduce waste and energy consumption while integrating environmentally friendly practices. These buildings are designed and constructed to offer safe, healthy, and sustainable living spaces. This study reviews existing research on green building development in Bangladesh and examines the performance of Karupannya Rangpur Ltd. Using temperature measurements, organizational records, and worker interviews, the study compares thermal performance, water use, and workplace conditions between green and conventional buildings. Results show that the green building achieved a LEED score of 71, maintained an average 4.33 °C lower indoor temperature compared to outdoors (vs. 1.67 °C in a conventional building), and saved up to 40% of monthly water through rainwater harvesting. Worker surveys indicated improved thermal comfort, reduced heat stress, and greater job satisfaction due to natural cooling, greenery, and clean indoor conditions. These findings may guide future research and sustainable construction practices in similar contexts.
