Integration of Sustainability Issues into the Regeneration of Urban Wasteland: From Theoretical Framework to Operational Monitoring Tool
Abstract: Regeneration of urban wastelands can contribute to revitalize and densify some portions of post-industrial European cities. A growing number of urban wasteland regenerations is now promoted by diverse territorial measures. However, it must be recognized that they mostly focus on “green constructions”, leaving aside holistic aspects of the concept of sustainability. Indeed, due to the inherent complexity of these projects, achieving the objectives of sustainable development is not spontaneous. It depends upon a proactive search for global quality, integrated into the project dynamics, and a continuous assessment of sustainability tailored to these sites. In reaction, this paper presents how a strategic integration of sustainability issues into urban wasteland regeneration projects can answer these targets. Preliminary research led to the creation of a theoretical framework, validated by a test application. Consequently, steps to transform this framework into an operational monitoring tool are presented. The resulting tool aims to concretely facilitate the regeneration of urban wastelands into truly sustainable neighborhoods. Urban strategy, wasteland regeneration, sustainable neighborhood, sustainability assessment, indicator system, monitoring tool.

An Operational Indicator System for the Integration of Sustainability into the Design Process of Urban Wasteland Regeneration Projects
In the context of sustainable development of European post-industrial cities, urban wastelands offer an important potential of surfaces to recapture. The regeneration of these sites is indeed an opportunity to simultaneously create density within the existing built fabric and revitalize some portions of cities and metropolitan areas. Although the launching of several initiatives of this type can be observed, their implication toward sustainable development is in most cases implicit and superficial. In point of fact, integration of sustainability into urban wasteland regeneration projects cannot be summarized by a mere density issue. It requires a proactive search for global quality, implemented in a participative way into the project dynamics, and a continuous monitoring of environmental, social and economic dimensions adapted to such projects. Specifically addressing these considerations, this paper introduces the development of an operational indicator system for the integration of sustainability into the design process of urban wasteland regeneration projects. It aims to provide a tool for structured and continuous evaluation, hinged on their specific characteristics, and to give useful basis to stakeholders involved in their management. Subsequently, the paper presents a first test application performed on a project underway in Switzerland, which validates its usability. Further work suggests the integration of the system into a digital monitoring tool in order to make it applicable to a variety of projects of this type.

Strategic Integration of Operational Assessment into the Transformation of Urban Wastelands to Sustainable Neighborhoods
It is now common knowledge, the regeneration of previously developed sites in urban areas can have positive impacts on the environment, the economy and the society as they constitute opportunities for the densification of the existing built fabric. In the context of the post-industrial European city, the urban wastelands offer thus an important potential of buildable surfaces and a chance to revitalize some portions of cities and metropolitan areas. Initiatives of this type are now strongly fostered by land use policies. However, it must be noted that in most cases references made to the concept of sustainable development are still often partial and superficial. Its integration requires a proactive and holistic approach, integrated in a participative way into the project dynamic, and a continuous assessment of the many dimensions of sustainability in regard with the specificity of these sites. The strategic integration of operational assessment into urban wastelands transformation projects is addressing specifically with these targets. Preliminary research projects have allowed to identify a first set of criteria and indicators based on specific characteristics of wasteland regeneration projects and to achieve a first test application on a concrete project. On the basis of that works, this paper shows the transposition of this set into a digital monitoring tool, entitled SIPRIUS, in order to create an operational assessment methodology that concretely facilitates the transformation of urban wastelands into sustainable neighborhoods.

Towards sustainable regeneration of disused urban areas : a monitoring tool to integrate assessment into the projects dynamics
Regeneration of disused urban areas, such as industrial brownfields or abandoned infrastructural zones, has received considerable attention in the context of post‐industrial European cities. Due to the inherent complexity of these projects, a holistic integration of sustainability objectives is far from being an automatic process. It depends upon a proactive search for global quality, integrated in a participative way in the project dynamics and a structured and continuous assessment of environmental, economic and social dimensions of sustainability, tailored to the specificities of such projects. Specifically focusing on these challenges, the ongoing research presented in this paper aims at developing a monitoring tool entitled SIPRIUS+. This new generation tool is a hybrid between a sustainability indicator system adapted to the issues raised by the regeneration of disused urban areas and a user‐friendly, web‐based monitoring software. SIPRIUS+ is designed to provide a strong basis to key stakeholders involved in the management of these projects and facilitates communication and participation with various public or private actors. This paper gives an overview of these objectives and a description of the steps of the tool’s design. Preliminary findings leading to future adaptations are presented through a case study: the Gare‐Lac neighborhood, a large disused urban area located in the city of Yverdon‐les‐Bains (Switzerland).

Chapitre de Livre
Système d'indicateurs pour les projets de régénération des friches urbaines
Le site Gare-Lac à Yverdon-les-Bains, sur lequel portent les travaux d'Urban Recovery, est particulièrement emblématique de la problématique de la régénération de friches urbaines. Saisissant cette opportunité, ce chapitre vise à présenter le système d’indicateurs pour les projets de régénération de friches urbaines intitulé SIPRIUS. La première partie de la contribution expose la démarche générale adoptée pour la conception de cet outil opérationnel d’évaluation de la durabilité, tandis que la seconde partie consiste en une application-test sur le projet conçu dans le cadre du Plan Directeur Localisé (PDL) Gare-Lac. Afin de démontrer la pertinence et l’applicabilité de SIPRIUS sur une étude de cas concrète, le projet de régénération du PDL est évalué à l'aide d'une sélection d’indicateurs représentatifs issus de chacun des trois piliers du développement durable.

Monitoring opérationnel pour l'intégration des enjeux de durabilité aux projets de régénération de friches urbaines
In a context where the territorial development stakeholders seek to limit urban sprawl, urban brownfields represent an important potential: their regeneration allows an increased density within the existing built fabric and a revitalization at the neighborhood scale. Many initiatives of this kind can be observed in Swiss and European agglomerations. However, because of their complex nature, a large number of them refer only in an implicit, partial, or superficial manner to the notion of sustainability. As such, it appears necessary to have means of assessment embedded in the current practice of urbanism, allowing a proactive, structured, and continuous integration of the sustainability issues in the dynamics of urban brownfield regeneration projects. In other terms, it implies to have the necessary means to implement an operational monitoring specifically adapted to this type of projects. Among the few sustainability evaluation approaches specific to urban brownfield regeneration projects, none allows a fully operational monitoring, sustaining the holistic integration of environmental, sociocultural and economic issues at the neighborhood scale. In parallel, we know that sustainability monitoring solutions have proved successful in other fields such as business management. Even if the indicators may differ, the underlying principles of monitoring stay the same. Consequently, this research suggests drawing on the hybridization of existing knowledge and skills to create a novel operational monitoring tool. The goal is to bring together elements from different disciplines in a new and innovative way, in order to obtain a new tool that efficiently combines the most relevant elements. The results of this research are structured in four steps. The first step is the critical analysis of existing know-how which allows identifying two distinct approaches that have the potential to meet the specific requirements for the operational monitoring tool. The second step corresponds to their adaptation and combination in order to create a new interactive and interdisciplinary tool, named SIPRIUS+. The third step allows verifying and optimizing the toolâs performances thanks to test applications on case studies located in Switzerland, Belgium, and France. Finally, the fourth step involves meeting the stakeholders of the three case studies in order to verify the level of added value of the tool as a support for the practical integration of sustainability in their project. What emerges from these interactions is that, whereas the use of such a tool implies a change in the management of these projects, the evolutions to adopt in order to include this practice appear not only feasible, but realistic and desired. The present thesis brings new, in-depth and up-to-date knowledge about the multiple issues associated with urban brownfield regeneration projects. This thesis also strives to bring a concrete contribution to the current practices by offering, to stakeholders involved in these interventions, new means to integrate and follow up sustainability criteria. The multiple investigations carried out highlight that the suggested approach provides insightful information and knowledge for better decision making, from the initial brownfield to the regenerated site.

SIPRIUS+ : A sustainability monitoring tool specifically designed for urban brownfields regeneration projects
One of the relevant strategies to limit the sprawl of post-industrial European cities is the regeneration of urban brownfields. This type of projects concentrates new development within already urbanized areas and contributes to their revitalization. Despite this, projects developed on urban brownfields are not automatically sustainable. It is explained by their inherent complex nature, due to the specificities of the site, the project process and the sustainability concept itself. Focusing on these challenges, SIPRIUS+ is an operational monitoring tool using an interdisciplinary approach. It supports a search for global quality, tailored to urban brownfields regeneration projects and integrated into the project dynamics. This new generation tool is a hybrid between a sustainability indicator system adapted to issues raised by brownfield regeneration and an user-friendly, web-based monitoring software. SIPRIUS+ assists practitioners in their decision-making: it facilitates the integration, assessment, and follow-up of sustainability indicators during the transformation of urban brownfields into new environmentally friendly and socially inclusive neighborhoods, respectful of future generations. This paper gives a description of the different steps of the tool’s design and an overview of its functionalities. Then, the main features of SIPRIUS+ are presented through a test application on a case study located in Yverdon-les-Bains (Switzerland).
