The 15-minute city has become an internationally recognized concept advocating for a people-centric urban model where residents should be able to meet most of their daily needs within a 15-minute walk or bike ride from their homes. The concept was introduced by Professor Carlos Moreno in 2015 following the COP21 conference in Paris, which concluded with the signing of the Paris Agreement. The idea proposes a practical and adaptable framework for introducing low-carbon mobility and creating a vibrant local economy to support more social interaction and more sustainable urban environments. Since then, the concept has been recognized with the 2021 Obel Award and has gained a notable recommendation in UN-Habitat's World Cities Report. Now, Professor Moreno is publishing the book titled “The 15-Minute City: A Solution to Saving Our Time and Our Planet” to showcase concrete examples and strategies for achieving better cities. ArchDaily had a chance to sit down with Professor Carlos Moreno to discuss these ideas, offering insight into Moreno’s urban thinking and the impact of this model.
Low Carbon: The Latest Architecture and News
Is Mass Timber the Key Element in a Low Carbon Future?
This article was originally published on Common Edge.
Chinese temples have stood for centuries, battered by wind and earthquakes, without a crack or timber out of place. They employ an ancient technique called “bracket set construction” that requires no nails or metal parts to connect wooden structural elements. Scandinavian stave churches are nearly as durable. Unsurprisingly, there are plenty of trees in Sweden and all over China.
So what is with the hype about innovation in “mass timber” construction over the past few years? As Boyce Thompson argues in his thoughtful new book, Innovations in Mass Timber: Sequestering Carbon with Style in Commercial Buildings (Schiffer Publishing), this will be the next big thing in “green” tech for architects feeling guilty about their costly titanium skins and outsized carbon footprints. The color photos show some impressive buildings in places where the wood industry has always been healthy, such as the Pacific Northwest and Scandinavia. The Japanese build log cabins with imported material that might as well be gold.
Harvesting Architecture: A Glimpse Into 3 Plant-Based Materials
For decades, our society has predominantly embraced an extractivist approach when formulating models for material manufacturing across diverse industries. While we now know that this model is unsustainable, a major question remains: So, how do we do it? We may be a while away from offering a definitive answer to this challenge. Still, it is exciting to note that, in a context marked by a challenging global and ecological horizon, the architectural community maintains a positive approach by pushing for a re-evaluation of what we make and how we make it.
This momentum may be gaining relevance due to the emergence of new, more environmentally conscious generations, such as Gen Z and Alpha. What is certain is that we are witnessing the development of new production philosophies, such as plant-based materials, which adopt practices aimed at favoring the use of resources derived from plants, reducing dependence on extractive processes, and promoting conscious and sustainable alternatives in various aspects of the manufacture and production of materials in architecture.
From New Buildings to Retrofit Projects: Solar Facade Systems for a Circular and Low-Carbon Architecture
The sun’s influence on human life encompasses multiple dimensions, from biological and developmental aspects to religious-mythological connotations in civilizations such as the Egyptians and Romans. Moreover, this influence extends to its use as a natural resource within the realm of science. In scientific pursuits, the continuous search to harness the sun as an energy source has been a constant throughout the years. Within this context, the discovery of the photovoltaic effect and its application have paved the way in the history of solar panels, starting from the first observations of Becquerel to the initial prototypes of Charles Fritts in the 19th century.
Nowadays, the energy obtained from the sun through devices such as solar panels has become one of the most widely used sources in regions like North America and Europe, contributing to the efforts for a complete transition to clean energy. The momentum in this transition has motivated the development of new technologies, such as SolarLab facade systems, that challenge the preconceived idea of what a solar panel looks like and where it can be installed. These systems converge with architecture to integrate them as aesthetic elements, serving as cladding for both retrofit projects and new buildings.

Has the Pandemic Halted the Road to Net-Zero Carbon?
With the magnitude and urgency of the immediate Covid-19 crisis worldwide, efforts have been concentrated on saving lives, rather than focusing on concerns related to the road to Net-zero carbon. Net Zero carbon in regards to construction is defined as when the amount of carbon emissions associated with the construction of a building and its completion is zero. A zero-energy building will have an overall zero net energy consumption; the total amount of energy used by the building annually is equal to the amount of renewable energy generated on-site.
As the climate emergency presents itself as a severe and existential threat, it is crucial that the road to net-zero carbon is resumed large-scale in both an architectural and commercial sense. Around the globe, efforts have been renewed in an attempt to tackle the almost inconceivable. According to the 2019 global status report for buildings and construction, the buildings and construction sector accounted for 36% of final energy use and process-related carbon emissions in 2018. Although carbon emissions were temporarily reduced during the peak of the pandemic, they are set to swiftly return to previous figures.
