A Conceptual biomimicry-inspired model for enhancing energy efficiency in high-rise buildings in Sri Lanka

Abstract

Rapid urbanization in Sri Lanka has led to increased energy consumption in high-rise buildings, particularly due to cooling demands in tropical climates. Conventional buildings with extensive glazed facades contribute to excessive solar heat gain and high reliance on mechanical systems. This study evaluates the potential of biomimicry-inspired strategies to improve energy efficiency in high-rise buildings. Two models, a conventional building and a biomimicry-inspired model, were developed and simulated using energy analysis tools in Revit under Colombo climatic conditions. The biomimicry-inspired model incorporates envelope strategies such as external shading, textured facade surfaces, and reflective roof coatings. The results indicate a reduction of approximately 25% in cooling energy consumption in the biomimicry-inspired model, along with decreases in lighting and equipment energy use. The study concludes that biomimicry-inspired envelope strategies can effectively enhance energy efficiency in tropical high-rise buildings.
