Adoption of Energy Efficiency Strategies and Challenges in The Design of High-Rise Commercial Buildings in Lagos, Nigeria

Abstract

The rapid urbanization in Lagos, Nigeria, has led to increased energy consumption in high-rise commercial buildings, necessitating the adoption of energy-efficient strategies. This study aims to assess the adoption levels of energy efficiency strategies by architects in Lagos and identify challenges hindering widespread implementation. The research objectives include identifying applicable energy efficiency strategies, assessing current adoption levels, and analyzing barriers to adoption. A quantitative approach was employed, utilizing a structured questionnaire distributed to 75 architects selected through stratified random sampling. Key findings reveal high adoption of passive design strategies and natural ventilation techniques, with solar energy dominating renewable sources. Smart technology adoption varies, while client budget constraints emerge as the primary barrier. The study concludes that while architects demonstrate awareness of energy efficiency principles, practical implementation faces challenges. Recommendations include targeted training programs, policy interventions, innovative financing mechanisms, and client education. This research contributes to the understanding of energy efficiency adoption in developing urban contexts, offering insights for policymakers, educators, and practitioners to promote sustainable building practices in Lagos and similar environments.
