In the vision of a model European city that is to be Competitive, Creative, Friendly and Consensual, the built framework (infrastructures and buildings) is an element which can be immediately perceived by all. It is therefore a direct stake.
In addition, the construction sector has the highest energy consumption of all the economic sectors in France (approximately 50 % of total national electricity consumption) and generates 23 % of national CO2 emissions. The BPW sector is undergoing great changes due to the increasing scarcity of energy and raw materials, which imposes the production of constructions with reduced energy requirements. This requires the emergence of new materials, equipment and trades which comply with (national and European) regulatory obligations and make use of tax incentives (sustainable development tax credit, zero-rate eco-loan, etc.) for new constructions, renovations or sustainable rehabilitations.
The main challenges of the EcoConstruction Strategic Committee are:
â€¢ The opening of new markets and creation of new services relating to the growth of activities concerned with renewable energies, the improvement of construction work or the upgrading of existing facilities to bring them into line with environmental standards thus increasing their efficiency. This includes the marketing of grouped project offers managing the construction-equipment-practice interface, of services for the active management of performance, of diagnosis and monitoring operations for existing constructions, and of new materials. It also includes the integration of renewable energies in the construction of new or already existing buildings and the use of ICTs and digital models right from the design stage in new constructions.
â€¢ New network management of urban services (water, waste, energy) over a broader area. Beyond the building scope, numerous eco-neighbourhood experiments support the development of ecoconstruction and promise the implantation of new equipment and infrastructures on a larger scale. At the same time, renewed reflections on the city as an ecosystem involve viewing buildings differently, and no longer as a subsystem that is integrated within a more global system.
The search for building and infrastructure efficiency for a better city life is at the heart of reflections which offer the building sector new growth opportunities. This growth is reinforced by a clear political positioning and ambitious objectives set by the Grenelle Environment Forum, which targets a 20 % decrease in energy consumption by 2020. The efficiency requirement of the building sector generates a need for new or adapted infrastructures along with their building methods and procedures, or for an increase in infrastructure life service thanks to improved diagnosis methods and maintenance.
