European market structure for integrated home renovation support service: Scope and comparison of the different kind of one stop shops

Abstract

<abstract> <p>While the retrofitting of the building stock seems to be an effective solution to reach the targets for 2049 greenhouse gas emission, the current rate and quality of work is still too low. This article first proposes a state-of-the-art methodology and a brief description of the barriers to renovation. The literature review identifies 26 major issues. Then, the one stop shops (OSS), which are introduced as a solution to these barriers, are described under different aspects according to their business model, the type of project owner targeted and the kind of services they offer with their support. Drawing on previous literature, this article proposes a classification framework. Then a comprehensive benchmark of 63 OSSs in Europe was conducted, allowing for a comparative analysis of the distribution of OSSs models across various countries and territories; it highlights the existing need in all countries, but also the disparity of support being provided. This examination revealed that selecting an appropriate OSS model cannot be solely based on factors like scope, ownership, or the existence of other OSSs. In the final section, a correlation study is made between several criteria (energy consumption and type, urbanization rate, construction date, climatic context, renovation rate etc.) that have been identified as being potentially indicative of renovation activities. The objective of this work is to provide an overview of the current context and emphasize effective strategies to accelerate the pace of renovation. By identifying and addressing the unique needs and challenges in each specific context, the goal is to promote efficient and streamlined renovation processes.</p> </abstract>
