Introduction - the cRRescendo Project

By the end of 2010, far over 10,000 people will live in modern, comfortable, healthy and energy-efficient homes due to the well-orchestrated sustainable developments of the metropolitan areas of Almere, Milton Keynes, Viladecans and Ajaccio, the medieval capital of the isle of Corsica. The harmonious cooperation between the cities within the EU Concerto programme will not only showcase the successful integration of polygeneration and renewable energy into a large number of ecobuildings, but will also provide the tools for a successful reprise in these towns, the associate communities and many other cities in Europe, in an ever swelling cRRescendo.

cRRescendo - objectives

"Combined Rational and Renewable Energy Strategies in Cities, for Existing and New Dwellings to ensure Optimal quality of life" is the full title of the project that is carried out by the four cities. It aims to integrate a major share of sustainability into over 3,000 new and existing homes and their energy infrastructure in order to demonstrate the possibility, feasibility and most importantly to meet the citizens’ wish to live in a comfortable energy efficient home in a healthy and clean environment. The demonstrations that are briefly described here (see top-menu) will be combined with extensive research, training and dissemination activities.

Research Activities

Technical issues concerning the efficient collection and monitoring of the main energy flows in the projects, such as the electricity, cooling and heating demands in the buildings, but also the electricity supply from each renewable electricity generator and renewable heating system, will be assessed. The non technical research activities have the objective to obtain a clear understanding of the socio economic aspects connected to the sustainability measures. Additional research action being undertaken includes research into the influence on occupant behaviour. In this respect research actions assess the impact the project has an effect on the energy consumption etc…, attitude towards EE and RES, and the perception of the quality of life. Moreover, research activities will focus on the influence on local policy, local economy, marketability, and cost reductions including the value of energy services.
