Sustainable construction

The environment and sustainable building are at the core of Bouygues Construction’s strategy. This major issue of our time is at the centre of our concerns and the key challenge our teams face. We build, of course, but our focus is on sustainable building in cooperation with industrial companies, associations and institutions, always with the same goal: building for the long-term by providing solutions to the future users of our buildings or amenities and preserving natural resources.

How can we develop and build in the context of “Zero net artificialisation” ?

23,000 hectares: this is the average annual area of natural, agricultural or forest land reallocated to urbanisation in France over recent years, the equivalent of 2.2 times the area of Paris, 33,000 football pitches or 19 million parking spaces. A figure which makes France one of the worst European students with regard to restraining real-estate development. The impact on biodiversity and CO2 emissions are such that there is an urgent need to hold back this effect. Although the target of Zero net artificialisation (ZAN) was written into the national biodiversity plan in July 2018, the strategy, method and means of bringing this into reality remains to be specified. Likewise the search for a denser, viable and liveable urban development model in large conurbations as well as town centres and small and medium-sized towns.

Photovoltaic : where are we?

“At the end of the crisis [health linked to the Covid-19 epidemic], the questions [regarding energy policy] will need to be readdressed.” So said Pascal Roger, president of the Federation of energy environment services (Fedene) to News Tank Cities on 01 April 2020. Currently, new renewable energies represent a prospect for ecological transition for this sector with photovoltaic in the lead, between giant power plants and innovative installations. Where are we ?

Energy renovation – the driving force behind new uses

While improving energy performance is essential during a renovation project, it is not the sole objective of project managers. Of equal importance are the key features aimed at incorporating different uses within a building. Issues such as planning, digitalisation, occupation of space, quality of life at work, etc. also need to be fully addressed.

How to design a welcoming city for people with disabilities

In February 2005, France adopted a law making it mandatory for cities to create a living environment adapted to people with disabilities by making urban areas accessible to all within 10 years. However, the additional time granted and the leniency shown due to difficulties cities faced in meeting the established deadlines have greatly brought down the initial goal.

Stéphanie Barrault, head of the Circular Design Experience project: applying all of the circular-economy principles to the construction sector

In France, the construction sector generates more than 40 million tonnes of waste every year and consumes large quantities of resources to meet the needs of renovation and new construction. A situation that contributes to threatening certain resources with scarcity, or even shortage, in the medium to long term. For example, this is the case with sand, of which the sector is a large consumer.

Using industrialisation to accelerate the energy revolution

One of the most significant potential areas for saving energy and greenhouse gases is the thermal renovation of buildings. But we are not renovating enough. The method needs to change, and this will probably happen via industrialisation. Industrialisation, boosted by the European EnergieSprong project, means improved performance and quality of use.

Reinventing collective housing, and more

The need to make cities denser and to develop original tools for collaboration is giving rise to new ways of approaching the design of urban planning and housing. There are two objectives: to get citizens involved in urban projects that affect them directly; and, in parallel, to promote the design of open and custom collective housing in their own image.

Objective: zero waste…

Regulatory pressure is growing on how building and public works waste is processed. The sector produces 70% of waste in France (245 million tonnes, 46 million tonnes of which from the construction sector).

Quai 22 – the city reinvented

This area will be a great place to work, take it easy and unwind. The location, known as ‘Quai 22’, with its mix of city life, water and nature, will be situated on the banks of the river Deûle in the European Metropolis of Lille.
