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.
