A new study reveals that traditional Italian roof designs inherently reduce heat loss without additional technology. Researchers in the U.S. demonstrated that specific roof proportions maximize heat retention, promoting energy conservation through geometry.
The study, led by engineer Adrian Bejan, analyzed roof shapes in Benevento, Italy, applying thermodynamics and fluid dynamics principles. They discovered that roof geometry directly impacts thermal insulation. Optimal heat retention occurs when the roof peak is less than 0.9 meters, ensuring laminar airflow.
These findings highlight the value of traditional knowledge in modern design. By incorporating these principles, new buildings can improve energy efficiency. This approach offers a cost-effective and universally accessible strategy for reducing global energy consumption, blending science and tradition for sustainable architecture.
