Energy Efficiency Strategies in Shopping Mall Design: A Case Study of Minna, Niger State, Nigeria
Abstract
Shopping complexes rank among the most energy-demanding commercial facility types, especially within hot-arid climatic zones where achieving indoor thermal comfort necessitates substantial mechanical cooling and extensive electric lighting. In Minna, Niger State, Nigeria, the conception and operation of retail centres contribute substantially to regional energy requirements, yet the incorporation of energy-conserving design approaches remains underdeveloped. This research examines the level of awareness, degree of implementation, and prospective application of energy-conserving design methods in shopping complexes within Minna, aiming to identify approaches that diminish energy usage while improving environmental efficiency and occupant well-being. A mixed methodological framework was adopted, incorporating questionnaire surveys involving 80 built environment professionals, detailed examination of four prominent retail centres, and systematic site observations. Data interpretation employed descriptive statistical methods and thematic analysis. Findings demonstrate that while professional consciousness regarding energy-conserving design approaches is remarkably elevated (93.3%), practical execution within shopping complexes remains irregular, hampered by financial limitations, regulatory shortcomings, and client preferences. Participants strongly advocated for early-stage incorporation of passive temperature regulation systems, natural airflow mechanisms, sustainable power technologies, and interdisciplinary cooperation. The investigation further established that thoughtful architectural configuration can substantially decrease HVAC requirements in hot-arid environments. The research concludes that technical capability, climatic suitability, and professional preparedness for energy conservation already exist within Minna; nevertheless, strengthened regulatory implementation, skill enhancement initiatives, and financial motivations remain necessary to transform these elements into widespread practice. The study proposes compulsory performance-oriented construction regulations, encouragement of sustainable power adoption, and improved utilization of quality indigenous materials to accomplish environmentally responsible, climate-adapted shopping complex designs.
