The fact that the population is ageing is not new. But the increase in healthy life expectancy and the massive retirement of baby boomers has significantly accelerated the phenomenon. For example, since 2015 there have been more over 65s than under 18s living in France! And in 2030, one Frenchman out of three will be […]

Towns and buildings desperately seeking biodiversity
UN experts have issued a chilling verdict: in cities and in the countryside, biodiversity is at death’s door. The good news, as with climate change, is that it is not too late. Although natural areas remain the priority, urban planners and developers in the broad sense must learn to build, to rebuild cities and buildings that will let ecosystems flourish, where ecological continuity really comes into its own.

Sustainable constructionEnergy 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.

The Floatgen project, the largest offshore wind turbine in France on which construction is soon due to be completed in the port of Saint-Nazaire, has won the Usine Nouvelle 2017 Renewable Energies Trophy for Energy Transition at the ceremony organised on Tuesday 16 May in the presence of Jean Jouzel, climatologist and former vice-president of GIEC.
Since 7 November, the 22nd Conference of the Parties (COP22) has been taking place in Marrakesh. The objective of this 2-week conference is to continue and to intensify the fight against climate change. Outside of the summit that brings together diplomats and heads of state from the entire world, the Bouygues Group, through its subsidiaries Bouygues Construction, Bouygues Immobilier, and Colas, is presenting its sustainable construction innovations.
Building and Civil Works generates 250 million tonnes of waste per year. Today, only 40% of this waste is reclaimed, yet the Energy Transition Act imposes a threshold of 70%, to be reached by 2020. Transitioning from a traditional, linear economy toward a circular economy means entirely rethinking how we manage a worksite's materials in order to produce in a more sustainable and sensible way.
Are European car manufacturers poised to switch to all-electric? On 10 September, MEPs in Brussels gave their support for draft legislation setting a 45% reduction in CO2 emissions from cars and vans under 3.5 tonnes by the year 2030, with an intermediate target of 20% by 2025. A much more ambitious roadmap than that of the European Commission, which tabled plans for a 30% reduction by 2030.
ABC came from Bouygues Construction Research and Development, in partnership with Valode & Pistre architects. It aims to promote self-sufficiency in water and energy, and seeks to optimise waste disposal. We met with Denis Valode, co-founder of Valode & Pistre architects.
