FACTORS INFLUENCING ENERGY EFFICIENCY SYSTEM IMPLEMENTATION AND MAINTENANCE IN RESIDENTIAL GREEN BUILDINGS

Abstract

Green residential buildings offer long-term environmental, economic, and social benefits, yet the effectiveness of their energy efficiency systems heavily depends on proper implementation and maintenance. This study investigates the key factors contributing to ineffective maintenance of energy-efficient systems in certified green residential buildings in Klang Valley, Malaysia. A structured questionnaire was distributed to residents and maintenance staff across three certified Green Building Index (GBI) developments. Despite a smaller-than-ideal sample size (n = 60), respondent diversity was maintained. Descriptive analysis revealed that financial limitations, inadequate maintenance planning, and weak management were primary barriers to maintaining energy efficiency. Additionally, the study incorporated perception-based findings, showing that most respondents recognized energy-efficient systems’ health, environmental, and societal benefits. The results highlight the importance of proactive maintenance strategies and training, and the role of perception in shaping energy practices. These insights support the development of integrated, perception-informed maintenance models to improve system performance and sustainability in green housing.
