The RenoWave guide offers a structured approach to promoting energy efficiency in multi-apartment buildings through the One-Stop-Shop (OSS) model. It emphasises the importance of targeted training as a tool for knowledge management, enabling stakeholders to understand and implement sustainable renovation practices effectively.

Municipalities are identified as key drivers of energy efficiency. The guide recommends tailored training sessions to equip local authorities with the skills to navigate regulatory frameworks, engage stakeholders, and apply the OSS model to streamline retrofitting projects. Practical formats such as webinars and workshops are encouraged to maximise participation and impact.

Building managers and service providers are also central to the OSS approach. The guide outlines training themes, including technical compliance, funding opportunities, and collaboration strategies. By enhancing their expertise, these professionals can better support residents and ensure high-quality renovation outcomes.

Finally, the guide highlights the role of residents and apartment owners in embracing energy-efficient living. Through accessible and engaging training, they are empowered to make informed decisions, benefit from OSS support, and contribute to the wider sustainability goals of their communities.
