Setting up One-Stop-Shops and implementing the EPBD – to make the RenoWave happen!
Project: RenoWave

The Guideline for OSS service providers is a practical guide for municipalities, regions, energy agencies, and organisations that plan to set up or strengthen a One-Stop-Shop (OSS) for apartment building renovation. Developed in line with the goals of the EU Energy Performance of Buildings Directive (EPBD), it helps local actors support homeowners through every step of the renovation process – from the first idea to implementation. The model is built around four key elements: data management, marketing and communication, homeowners’ forums, and technical assistance. Together, they provide a clear and user-friendly framework to make building renovation more efficient, accessible, and trusted across communities.
As part of the RenoWave project, one-stop-shop agencies (OSS) will start operating in several countries of the Baltic Sea region to promote and foster the renovation of multi-apartment buildings. This service has not been available in these regions/municipalities so far. In some places, this will be even a new model for engaging with homeowners.
Considering how long and complicated the process of renovating multi-apartment buildings could be, with several periods and activities, we understand that the OSS user will not be a one-time user or visitor. The OSS visitor will use the OSS services multiple times at different building renovation stages, including consideration, decision-making, planning, financing, implementation, and experience.
Focusing on the user's needs and the problems that the OSS could solve is essential to building a solid and long-lasting relationship with our target groups. The main result of the RenoWave project will be a One-Stop-Shop Module that includes a Data Handling Methodology, a Marketing and Communication Module, a Guide for Establishing Forums, and a Technical Assistance Module. The OSS Module will consist of traditional and additional OSS services that cover all the steps necessary to initiate and implement energy-efficiency renovation projects in multi-apartment buildings.
