In the wake of tackling energy poverty by its roots and protecting vulnerable groups, the European Commission introduced the so-called Renovation Wave, aiming to renovate 35 million inefficient buildings by 2050. However, even though the Renovation Wave was aimed to tackle energy poverty, recent studies have shown that renovation policies have failed to address energy poverty as renovation and social policies lack intersectoral integration resulting in the exclusion of vulnerable groups and an increased risk of social inequity. Moreover, various scholars have tried to identify vulnerability indicators that give rise to energy poverty; however, these have only focused on identifying socio-
economic and energy indicators. Consequently, scholars have called to include justice in renovation policies and explore how vulnerable groups can be identified. To address this knowledge gap, the following main research question was formulated:

Using a Case-Study Mixed Methods (CS-MM) approach, how can justice be included in renovation policies considering the socio-spatial vulnerability to energy poverty?

The results showed that by identifying vulnerable groups based on a locally developed index of the socio-spatial vulnerability to energy poverty and acknowledging their vulnerability, recognitional justice can be included in renovation policies. Besides, identifying tailored policy strategies in a multi-stakeholder environment that, on the one hand, focus on the distribution of renovation resources based on the needs and characteristics of the identified vulnerable groups and, on the other hand, on how the vulnerable groups can be included in the decision-making, distributional and procedural justice can be included in renovation policies. Thus, it can be concluded that by deploying the current CS-MM approach, justice can be included. 
The outcomes of the present study are twofold. Firstly, from a scientific perspective, the present study contributes to the current body of scientific knowledge on: (1) how vulnerable groups in need of renovation can be identified, (2) how justice can be included in renovation policies to address energy poverty and (3) how a CS-MM approach can be deployed to research how justice can be included in renovation policies considering the socio-spatial vulnerability to energy poverty. Secondly, from a societal perspective, this study provides insights to improve policy strategies that enable local decision-makers to identify vulnerable groups and include justice in renovation, considering the socio-spatial vulnerability to energy poverty.
