Abstract

Green roofing systems offer a sustainable approach to eco-friendly solution to reducing the indoor temperature and improving overall indoor thermal comfort, especially in tropical and subtropical climates like Bangladesh. Khulna, the south-western region of Bangladesh, faces high temperatures and humidity during its summer months in every year. This research examines the impact of green roofing systems on reducing indoor temperatures in Buildings in Khulna region. By employing a combination of shrubs and herbs in a 3-inch soil layer and radiant barriers with aluminum foil, this study explores green roofing as an innovative solution for sustainable building design. In this study, a relation is made between miniature model room and traditional room. Traditional rooftops are compared with the miniature models’ rooftops constructed with shrub and herb plants. A mean indoor temperature reduction about 1.83℃ and 1.68℃ was found for green roofs with shrubs and herbs respectively while reduction about 3.4℃ and 3.24℃ from outdoor temperature found after analyzing the temperature data collected over July-September 2024. These findings were nearly consistent with the analyzed data found from practical survey on 78 buildings in Khulna, affirming the reliability and applicability of the miniature model experiments in real-world scenarios. The results highlight how green roofs can be used as an effective passive cooling strategy with a cost effective and locally adaptable solutions to address urban heat and energy challenges with the alignment of United Nations Sustainable Development Goals (SDGs).
