Abstract: Energy efficiency labelling in residential buildings is an important policy tool developed by government and industry initiative to establish a minimum level of energy performance to encourage stakeholders to invest in energy efficient homes. Building energy codes and labels are the two pillars for policy implementation of energy efficiency in buildings. Building energy codes establish the standards to be adhered. Energy labels ensure the minimum energy performance standards to be met and also provide a comparison with other similar buildings by setting benchmarks for improved performance. To ensure penetration of better building energy codes and policies, which includes labelling, certification and incentive programs are needed all over the world in every country and the ways to achieve them is through the sharing of best practices, capacity building and training.
This study starts by evaluating the best practices followed by 11 countries to establish the design considerations and important aspects to develop a proper framework for the labelling program to be implemented in India for residential buildings. Various parameters have been selected with respect to label design, assessment methods, disclosure criteria and framework of the labelling programs. It establishes a base for further stakeholder engagement, developing a framework and scope for improvement for the upcoming labelling program to be developed in India. A market recognition survey on the basis of the literature review of best practices has been done by a panel of internal experts. On the basis of the findings, a comparative study has been conducted to study the impact of building envelope on the annual electricity consumption. Annual building energy simulation of two types of housing categories EWS (Economically weaker section) and MIG (Medium Income Group) has been performed and on the basis of these the impact of energy efficient building materials has been found out. It also mentions potential barriers to the implementation of the program and provides probable solutions and policy recommendations for the same.
