AN EVALUATION OF CLIMATE RESPONSIVE FAÇADE DESIGN FEATURES OF KINGS TOWER, LAGOS, BASED ON MAHONEY TABLES

With the increased urbanization of tropical areas like Lagos, Nigeria, the need for climate-responsive design in high-rise buildings has grown. These design strategies seek to improve thermal comfort, energy efficiency, and environmental sustainability. This study examines how King's Tower, a well-known commercial high-rise in Lagos, incorporates bioclimatic features into its façade design. The Mahoney Tables, a bioclimatic tool typically created for low-rise buildings, were used as a baseline to produce design recommendations for orientation, ventilation, shading, and material selection with 2024 climate data, particular to Lagos. In order to determine how well King's Tower adheres to these suggestions, a comparative evaluation matrix was subsequently created, supported by descriptive examination of architectural drawings and photographic material. The results show partial compliance in orientation and material reflectivity and full compliance in the use of low thermal mass, lightweight materials. The building's dependence on mechanical cooling systems is highlighted by its non-compliance with important passive measures, including natural ventilation and façade shading. These findings highlight the drawbacks of using standard bioclimatic techniques on high-rise buildings, which frequently have functional and spatial complexity that is not taken into consideration by conventional models. The study fills a significant vacuum in the literature on sustainable urban development by putting forth an updated framework specifically designed for vertical architecture in hot-humid regions. By providing low-energy, climate-responsive solutions for high-density spaces, it supports the Sustainable Development Goals and emphasizes the significance of adjusting passive design principles to local climatic circumstances.
