The concept underpinning STUNNING is to build a community of stakeholders around a web-based knowledge sharing platform (KSP) that provides key facts on renovation packages, business models and business cases. Stakeholder engagement activities are then articulated around this platform.
In WP2 (Stakeholder engagement and knowledge sharing platform), actions targeting stakeholders of the renovation sector have been implemented to engage them (workshops, webinars, newsletters, surveys, etc; see also WP6). In parallel, regular publications were made on the Renovation Hub to present the outcomes of WP3, WP4 and WP5 and enable the exchange of information and best practices among stakeholders.
In WP3 (Benchmark of innovative refurbishment packages and business models), a common database structure has been designed. About 371 renovation cases have then been collected and reviewed, including French, Spanish and German renovation cases. A cost-benefit method has been developed to estimate the profitability of renovation projects. An additional Monte Carlo assessment risk methodology has been implemented to identify the main variables that could have an impact on this profitability.
In WP4 (Identification of barriers that slow down replication), various activities have been performed to understand the dynamics behind the market barriers that have impeded the EU to achieve the yearly targeted renovation rates and general objectives of the EPBD. A preliminary analysis of the renovation market mechanisms and trends was conducted through the observation of macroeconomic indicators, along with energy efficiency policy instruments and more generalized data on deep renovations. Through a review of existing literature, partner market knowledge as well as external consultation, interview processes and case studies, the main barriers were then defined and contextualized. Solutions for the alleviation of these barriers where offered.
In WP5 (Promotion of new business models and validation through business cases), initial effort focussed on the creation of a dedicated Business Models’ (BMs) Database (DB) collecting innovative business models for building renovation, that proved their success in different geographical contexts and for specific building typologies. According to the main barriers encountered in the renovation process, the most promising BMs were identified. A set of 14 Business Cases presenting their application in a real environment has been investigated with the aim of evaluating and highlighting their distinctive elements as well as their common features towards potential optimization. General recommendations have been deduced to enable the identification of replicable and adaptable models. The BM were then promoted through the Renovation Hub, the final publication and other specific activities.
In WP6 (Communication, Dissemination and exploitation of project results), the STUNNING website and social media were constantly kept up to date. The partners created and disseminated further printed and digital means of communication, conducted a stronger interaction with stakeholders and potential registrants for the Renovation Hub via webinars, publications, participations to events as well as the organisation of a final conference. The STUNNING final publication ensured the further dissemination of project results in a summarised, attractive and understandable manner. The partners finalised their exploitation strategies for the most promising results (which include the Renovation Hub, the CBA methodology, the BM database and the final publication). A business plan was created for the Renovation Hub, which was identified as the key exploitable result of the project.
