In the sweltering heat of Gorontalo City, Indonesia, a groundbreaking study is redefining how we think about thermal comfort in educational buildings. Led by Niniek Pratiwi, a specialist in building architecture at Universitas Negeri Gorontalo, this research is not just about making classrooms more comfortable—it’s about revolutionizing energy efficiency in the construction industry.
Pratiwi’s work, published in the Sustinere: Journal of Environment and Sustainability, focuses on State Elementary School 91 Sipatana. The school, like many in hot and humid climates, struggles with maintaining a comfortable learning environment. High indoor temperatures can lead to decreased student performance, making thermal comfort a critical factor in educational outcomes. “Comfortable learning environments are known to enhance students’ learning outcomes,” Pratiwi emphasizes, highlighting the real-world impact of her research.
The study employed advanced building performance simulation tools, Ladybugs and Honeybees, to model various building configurations. The goal was to find the most effective combination of materials and design features to achieve optimal thermal comfort. Pratiwi and her team measured room temperatures using an Elitech GSP-6 data logger, collecting data over a 12-hour period. The results were striking.
Among the different models tested, Model 3 stood out. This configuration featured a metal roof with cool roof technology, concrete walls, and enhanced ventilation. The cool roof technology, which reflects more sunlight and absorbs less heat, proved to be a game-changer. “It maintained a roof surface temperature just above 25°C and an indoor air temperature close to 30°C,” Pratiwi reports, demonstrating the effectiveness of cool roof technology and adequate ventilation in reducing heat accumulation.
The implications for the energy sector are profound. As buildings become more energy-efficient, the demand for cooling systems could decrease significantly. This not only reduces operational costs but also lowers the carbon footprint of educational institutions. For the construction industry, the findings suggest a shift towards sustainable materials and design practices that prioritize thermal comfort without compromising on energy efficiency.
Pratiwi’s research is a beacon for future developments in sustainable building practices. As more schools and commercial buildings adopt similar technologies, we can expect a significant reduction in energy consumption and a corresponding decrease in greenhouse gas emissions. This study is a testament to the power of innovative research in driving sustainable change.
For the energy sector, the message is clear: investing in sustainable building technologies is not just an environmental imperative but also a commercial opportunity. As Pratiwi’s work shows, the future of construction lies in creating buildings that are not only comfortable but also energy-efficient and environmentally friendly. The journey towards sustainable building practices has just begun, and the path forward is illuminated by groundbreaking research like Pratiwi’s.
