Enhancing sustainable residential energy practices through the implementation of an energy-efficient labelling system for domestic consumers in Sri Lanka

Abstract

This paper addresses the imperative need for an energy-efficient labelling system tai-lored for domestic consumers in Sri Lanka. The country faces challenges related to energy dependencies, high energy costs for primary and secondary sources, and lower per capita electricity consumption compared to neighboring countries. The objective of this research is to contribute to sustainable energy practices and enhance residential energy efficiency in Sri Lanka by introducing a comprehensive energy-efficient labelling system for domestic consumers.

The findings of this study are anticipated to inform energy policies, enhance Energy Se-curity, assist in Energy Resource Assessment, contribute to accurate Demand Forecasting,guide Infrastructure Energy Requirements, support Energy Efficiency initiatives, facilitate Renewable Energy Integration, consider Environmental Implications, weigh Economic Fac-tors, promote International Collaboration, and establish a robust Policy and Regulatory Framework. The proposed energy-efficient labelling system for domestic consumers aims to raise awareness, induce behavioral changes, and provide incentives for energy-efficient practices, ultimately reducing carbon footprints and fostering a more sustainable residential sector.

In conclusion, this research significantly enhances our comprehension of energy consump-tion in residential buildings, particularly in Colombo, Sri Lanka. The study exposes a lack of awareness and understanding of energy usage among domestic consumers, emphasizing the potential benefits of integrating renewable energy sources and implementing time-of-use tariffs for optimizing efficiency. Findings underscore the importance of natural lighting, ven-tilation, and building envelope efficiency in reducing energy consumption and improving in-door comfort. Additionally, exploration of biogas for cooking and IoT-based solutions reveals promising opportunities for sustainable energy practices. The proposed IoT-based solution,utilizing JavaScript, emerges as a key enabler for real-time energy monitoring and intelligent energy management, demonstrating scalability for future implementations. While acknowl-edging research limitations, including sample size and case study scope, the paper suggests expanding samples and conducting comprehensive case studies for validation. Practical im-plications advocate for tailored energy-efficient labeling systems in Colombo, proposing tax relaxation for start-rated consumers to promote sustainability. This research serves as a foundational step toward a more sustainable energy future, offering valuable guidance for policymakers, stakeholders, and energy-conscious consumers, with potential for continued progress and environmental responsibility through further research in the field.
