Assessing the Impact of Smart Building Technologies on Energy Efficiency in Nigeria: Case Study Insights from Real-World Applications

Abstract

As Nigeria continues to face growing urbanization and energy demand, the implementation of smart building technologies (SBTs) is emerging as a viable solution to address energy efficiency and operational costs. This study investigates the effectiveness of key smart building technologies in enhancing energy efficiency within the Nigerian context. The research focuses on automated Smart HVAC systems, smart lighting, energy management systems (EMS), and the integration of renewable energy sources. By using multiple regression analysis (MRA) and multi-attribute decision analysis (MADA), the study quantifies the relationship between these technologies and energy performance outcomes such as energy savings, cost reduction, and occupant comfort. The findings reveal significant improvements in energy efficiency, operational costs, and return on investment (ROI) from the use of these technologies. The study concludes that smart building technologies offer substantial potential for sustainable development in Nigeria’s construction sector, particularly in addressing the country’s energy efficiency challenges.
