Wal-e-Cites-ENR-LG2

Le projet Wal-e-Cites-ENR-LG2 aborde le défi énergétique d’une transformation vers un environnement bâti intelligent. Il consiste à développer un outil informatique évolutif d'aide à la décision stratégique dédié à la cartographie énergétique multi-échelle et dynamique ainsi qu'à l'analyse de données énergétiques pour une gestion intégrée de l'énergie sur le territoire en transition de la Wallonie. Au niveau temporel, l'échelle de représentation variera d'un quart d'heure à une année. Cet outil sera développé à l'aide d'un système d'information géographique et de l'intégration de sources de données multiples provenant, d'une part, de données mesurées dynamiques collectées par des compteurs intelligents, des systèmes GTC de bâtiments, des résultats détaillés de monitoring de bâtiments et de systèmes énergétiques et, d'autre part, de données statiques (données cadastrales, données empiriques, modélisations, géolocalisation, compteurs classiques, ...). La structure de l'outil créé sera évolutive pour s'adapter en permanence à l'ajout de nouvelles données, ce qui lui permettra de s'adapter au développement probable des technologies intelligentes dans les villes wallonnes au cours des prochaines années et décennies. L'outil développé sera validé sur des sites pilotes en Wallonie.
The Wal-e-Cites-ENR-LG2 project addresses the energy challenge of transforming into a smart built environment. It consists of developing a strategic decision support evolving digital tool dedicated to multi-scale and dynamic energy mapping as well as the analysis of energy data for integrated energy management in the transitioning territory of Wallonia. At the time level, the scale of representation will vary from a quarter of an hour to a year. This tool will be developed using a geographic information system and the integration of multiple data sources, on the one hand, from dynamic measured data collected by smart meters, GTC systems of buildings, detailed results of monitoring buildings and energy systems and, on the other hand, static data (cadastral data, empirical data, modeling, geolocation, conventional meters, etc.). The created tool structure will be evolving to continuously adapt to the addition of new data, which will enable it to adapt to the likely development of smart technologies in Walloon cities in the coming years and decades. The developed tool will be validated on pilot sites in Wallonia.

VALUE ADDED

Even if it is now welcomed by most of the EU cities, public involvement in decision-making and planning is still a challenge. The major problems facing Europe can indeed not be addressed using entirely local bottom-up approaches. This also requires strategic, coordinated responses. VALUE+ will demonstrate how cities can best integrate bottom-up and top-down approaches, but also how to build on community participation to generate local growth, innovation and resilience strategies. The City of Liege is the operational partner associated to ULg for this action-research project.

SOLEN (2012-2014) SOlutions for Low Energy Neighbourhoods

The aim of SOLEN is to develop solutions to improve energy efficiency of existing Walloon neighborhoods. Three main axes are studied and combined: the sustainable building, the sustainable mobility and the integration of renewable energies to tend to low / zero energy neighborhoods. An assessment tool dedicated to building performance and transportation in neighborhoods will be developed.

SIMBA (2009-2013) Simulation Multi-physique du Bâtiment

This research aims to integrate simulation tools developed by aeronautic sector into building physics. These tools have become indispensable because of energy performance requirements for buildings construction or renovation. Their use will also permit to get a better understanding of complexes phenomena occurring in buildings such as natural convection, forced convection, radiation or also conduction.

SUN (2009-2012) Sustainable Urban Neighbourhoods

«Sustainable neighbourhoods» are trendy and developing in all European regions, but most often on greenfields. Is it really sustainable? What about urban sprawl and what about existing urban neighbourhoods? How to raise their attractiveness face to new «sustainable» peri-urban developments? How to reverse dereliction and deprivation processes operating in some urban neighbourhoods? Sustainability is too often understood as referring to the sole environment and energy saving concerns, while it is a much more integrated and holistic concept including cultural and social issues, as well as economic development.
