Wiring the World

Words by Charis Brice

The green transition is one of the great human projects of this century. It’s not built by policy alone, but by the sweat and grit of those who make it happen.

Europe’s building stock is aging and inefficient. Approximately 220 million of its buildings were constructed pre-2000; a time before energy ratings became mandatory, when double-glazed windows were an unnecessary luxury and heating ran on fossil fuels without smart controls.

But in the next decades, policy aims to bring the oldest building stock in the world in line with the realities of climate change. That will be done by adding insulation, improving cooling and heating systems, and using renewables to run buildings. The Energy Performance of Buildings Directive from the European Commission aims to fully decarbonise Europe’s buildings by 2050.

But the urgent need for renewables is not just a European issue – it is a global one. The entire world must contend with the effects of a changing climate, and using renovation as a response to these changes requires a workforce that can quickly adapt to and learn new technologies and processes.

By necessity, electricians become energy specialists, builders take on retrofit coordination, and entire crews develop sustainability expertise previously unheard of in their field.

This VIEWS honours the thousands of humans who do the work to help our buildings become more sustainable and allow us to leave a gentler mark on our planet.

Azimut 360 completed a solar installation at the Mediterranean Institute for Management ISMM in Tetouan, Morocco, delivering hands-on training for women of the cooperative Sunpower. The project was supported by the City Hall of Barcelona in collaboration with the City Hall of Tetouan. Photo: Azimut 360 
Barcelona has tripled its municipal solar power potential since 2023, putting 91 new installations into operation in just two years, reaching a total of 268 active facilities with 11,449 kWp of installed capacity. Photo: Azimut 360

By repurposing an abandoned yet historically significant structure, this initiative prioritises affordability, sustainability, and community cohesion. Photo: Build Better Lives
Through a participatory co-design process, residents and stakeholders actively shaped the project, combining heritage preservation and forward-thinking housing solutions. Photo: Build Better Lives
The following photos show the before (left), during (right), and after (below) photos show another project from the Build Better Lives inspiring stories repository which was led by the Municipality of Bordeaux & Aquitanis in collaboration with Lacaton & Vassal architectes, Frédéric Druot Architecture and Christophe Hutin Architecture. They offer a glimpse of the renovation transformation which added an outdoor space to 530 social housing units in France. Photos: Philippe Ruault
