Can urban greening come to the rescue of life in cities?
The summer of 2022 has sadly left its mark on the history of France. Some people see it as the clear consequences, others hear alarm bells ringing... With an unprecedented drought, repeated dramatic fires and record temperatures, France, like other countries around the world, is overheating! This fact highlights the vital and indeed health-giving role played by urban greening.
“De-gendering” cities: a new criterion of attractiveness?
Cities are made by men and for men: they have historically been planned and designed to reflect the traditional role of the male gender. This is a considerable problem since all genders should have equity in sharing the public space.
Building schools in modular wood
Interview with Marina Da Silva Carvalhais, R&D projects and Wood Construction Innovations (WeWood).
Flax: A fibre of the future for construction?
Resistant, light, efficient, ecological… Flax is used in construction on land and even on the sea! In 2022, the Netherlands inaugurated the world’s first linen bridge. A navigator used it to build the hull of his boat… Can this plant material really meet the needs of urban construction?
Is digitalisation the key to building differently
Attracting talent, mitigating climate change, and improving productivity: These are the construction sector's three main challenges. BIM and various digital tools offer useful solutions, but these are not enough.
What if your sites were supplied via rivers instead of roads?
Faced with the current energy situation, we must urgently find alternative solutions that will enable us to change the ways we produce and transport our materials. Among the solutions considered, one of the priorities – particularly for the industrial sector – is to find means of transport that are more energy-efficient and less harmful to local residents. Focus on river transport.
New challenges in public space
Today, public spaces are facing new challenges – societal, environmental, political, technological and economic – and must deal with the uncertainty of a changing world. How can public spaces be designed to meet the various expectations of society while also being able to adapt to future developments?
Free public transport: issues and positions of the key players in the debate
The issue of free public transport was widely debated in France’s 2020 municipal elections. Its presence on the headlines of many campaign documents demonstrates the political, environmental and societal nature of the issue. Several issues arise from the implementation of such a public policy. We examine the positions of the key stakeholders in the debate.
How do you design green roofs?
Green roofs are on the up and up. And for good reason! They have many environmental, economic and social benefits. In addition to their aesthetic appeal, they can promote biodiversity, improve the insulation of buildings and retain rainwater. Recent research conducted by ecologists is improving our understanding of the conditions under which rooftop vegetation thrives and develops, and assessing the quality of ecosystem services provided by different types of roofs. We consider the factors behind the design choices for such ecosystems.
What kind of governance is appropriate for a convivial city?
At the request of Bouygues Construction and La République des Hyper Voisins, six students from the École Urbaine at Sciences Po Paris worked for nine months on creating conviviality in urban areas. The proposed exploration strategy is to create the conditions for conviviality by introducing a professionally-structured form of citizen action on a micro-local scale. Explore their recommendations for the forms of governance that are most conducive to the emergence of convivial spaces, based on eleven areas of investigation in France and Switzerland.
How do players in US construction innovate?
Interview with Viviane André, an analyst at Winnovation, a Bouygues Group subsidiary.
Should we build higher and higher to fight against land artificialisation?
The fight against urban sprawl and land artificialisation is a national priority that is pushing those in the building sector to look for solutions to make cities denser. One of these solutions is to build ever taller buildings. A controversial issue.
The French Towns Adopting Sustainable Construction Charters
Many towns and cities are looking for a way to remodel their urban planning to give them resilience in the face of climate issues. One such solution is to rally the stakeholders in an area - residents, companies and local authorities - to move towards housing solutions that are innovative, sustainable and accessible to all: that is the cited goal of the ‘sustainable construction charters’ emerging around France.
How much will the ecological transition cost the construction industry?
In the last segment of its sixth activity report, the GIEC specifies very clearly that on the economic level, the ecological transition will prove less expensive for the global economy than if we do nothing. Several sectors are highly exposed to this issue, in particular transport, energy and construction. But acting, how much will it cost? The subject is a complex one but initial estimates are starting to be seen.
Guide to Regreening Cities
Focus on planting initiatives to regreen cities including urban canopies to provide plant life without digging, planters with automatic watering or rainwater harvesting systems, “oasis” schoolyards, and urban mini-forests.
Tackling traffic congestion in cities
Tackling traffic congestion has always been a major challenge for local authorities. Many different approaches have been attempted, including adding lanes, removing lanes and multimodal transport.
Towards a more “ecosystemic” energy performance of buildings
Controlling energy consumption has become an environmental, social and economic necessity, due to the numerous impacts on the biosphere and society as a whole: climate change, depletion of natural resources, deterioration of health, etc.

Cities to be: “From aspirational metropolis to inspirational city”
Providing levers for attaining the goals of sustainable development, such is the ambition of Cities to Be. In concrete terms, this means pooling experiences, solutions and best practices, generating momentum among the territories, and persuading players of the building sector to commit to such goals. All in the aim of creating a denser, more resilient city that offers, quite simply, a pleasant way of life.

Openness and sharing: sources of value for the world to come…
How to be attractive, create value and be scalable is the challenge for office buildings in order to meet all the complexity of an increasingly pressurised market. The uses and structure of such buildings require urgent rethinking in order to meet the new expectations of their occupants, as well as health and environmental issues. Solutions exist, but such changes must be anticipated in order to be implemented effectively.

Preserving biodiversity in urban regeneration and construction projects
Around 28% of the world’s animal and plant species are now under threat of extinction . This includes one in four mammal species, one in seven birds and more than one in three amphibians, as well as a third of conifer species. Scientists are warning of an ongoing collapse of biodiversity, with some even talking about a “sixth mass extinction”. The principal causes are the destruction and fragmentation of the habitats of these species, the overexploitation of ecosystems, the development of invasive species, climate change and pollution and eutrophication (the introduction of nitrogen, phosphorus and other excess nutrients into the environment). Many of these factors are caused by human activities, which have such a strong and rapid influence that the biosphere is unable to adapt to them. What action can we take to halt the trend and prevent ourselves from crossing critical thresholds? Pierre Lopez, Sustainable Construction Project Manager at Bouygues Bâtiment Nord-Est, gives us his point of view on the construction sector.
