ABSTRACT

Having an environmentally friendly and energy-efficient house is a critical requirement today as this has a positive impact on residents and the surrounding environment, which supports the improvement of the three main pillars of the concept of sustainable development. However, many factors influence the energy-saving behaviour of households, especially the millennial generation. This study aims to identify and analyse the millennial generation's behaviour towards energy efficiency activities in environmentally friendly houses using the Theory of Planned Behaviour. The quantitative method was applied with a cross-sectional survey method and analysis with structural equation modelling. The respondents were 200 millennials in Malang and Surabaya with purposive random sampling. The analysis resulted that attitudes have a positive effect of 0.22, subjective norms have a positive effect of 0.44, and perceived behavioural control has a positive effect of 0.19 on the energy efficiency intention. The results also showed that perceived behavioural control and energy efficiency intention partially have a positive effect of 0.61 on energy efficiency behaviour. Based on the analysis and hypothesis testing results, it is concluded that subjective norm and attitudes positively and significantly affect the millennial generation's energy efficiency intention, besides perceived behavioural control. Thus, this study will support the sustainable development stakeholders so that it will lead to understanding the millennials' behaviour and reasons for safe energy in eco-friendly homes concerning appropriate energy usage rules.
