Judicious use of energy sources assumes prime importance in attaining energy efficient behaviours and this also helps to achieve environmental protection. This study aims to develop the most conducive energy efficient and environment-friendly behavioural assessment framework for household energy consumers in India. The multi-grade fuzzy and Importance Performance Analysis (IPA) are applied to develop this assessment framework. The case study has been conducted with residents of XYZ residents’ association in India. The results obtained from the case-study Energy Efficiency Behavioural (EEB) Index is 6.6 which belongs to ‘Energy Efficient’. The IPA analysis classified the weaker attributes of the case residents’ association. The appropriate suggestions are provided to improve the weaker attributes. This framework will enable energy auditors, residents’ association, and government to periodically evaluate the EEB.
