The construction industry is one of the largest in the world, and cement and concrete are literally the building blocks of its success. Evolving from prehistoric caves to today’s towering skyscrapers, concrete structures have and will continue to be vital components of modern civilization, providing long-lasting, reliable support for buildings, roads, bridges, tunnels and dams. So much so that concrete is the most consumed material on Earth, second only to water, while the steel used to reinforce it is by far the most commonly used metal. But this doesn’t come without high environmental costs: concrete accounts for 8% of global CO2 emissions, much of which come from the extraction and transportation of aggregate materials such as sand, gravel and crushed stone.

What COP27 Meant for Architecture and the Construction Industry
The 2022 United Nations Conference of the Parties, more commonly referred to as COP27, was held between November 6 and November 18, 2022, in Sharm El Sheikh, Egypt. The conference included more than 90 heads of state and an estimated 35,000 representatives, or delegates, from 190 countries. Aimed at encouraging and guiding countries to take effective action against climate change, the next edition of these conferences, COP28, is already scheduled from 30 November to 12 December 2023, in the United Arab Emirates. The CEO of the Abu Dhabi National Oil Co, an oil company chief who also oversees renewable energy efforts in the Emirates, was appointed to preside over the negotiations and talks, which led to a wave of criticism from environmental activists.
Edible Cement: Innovative Material That Uses Food Waste in Civil Construction
Add cabbage leaves, orange peels, onions, bananas and a few slices of pumpkin to get... cement. That's right, researchers from the University of Tokyo in Japan have developed a technique through which it is possible to produce cement from food waste. Besides being used in construction, the innovative initiative is edible as well. You can make boiled cement into a delicious meal by adjusting flavors, adding seasonings, and breaking it into pieces.
Spanish Architects Create Moisture-Absorbing Mortar from Construction Waste
Cities are filled with waste materials and the need to reuse existing resources has become key in fighting the increase in waste production. More than a third of all the waste generated in the EU comes from construction and demolition, containing different materials such as glass, concrete, bricks and ceramics. But how to manage this staggering amount of waste production from construction? According to the Spanish Law on Waste and Contaminating Soils, concrete and ceramic waste with no considerable processing can both be reused in construction . By combining reused material waste with technology, architectural design can create innovative solutions that contribute to minimizing environmental impact.
What is Urban Resiliency?
At a historical moment when industrialization and urbanization are continuing at a fast and predatory pace, we need to design and produce spaces that can adapt to new realities. Based on this need, concepts that can guide the transformation and production of future cities emerge.
What Are Green Corridors?
Green corridors, or biodiversity corridors, are large portions of land that receive coordinated actions to protect biological diversity. According to Brazil’s National System of Nature Conservation Units, they strengthen and connect protected areas, encouraging low-impact use by implementing a more comprehensive, decentralized and participatory conservation alternative.
Architecture as Collaboration Between Human and Non-Human Species
Nowadays, much is said about the importance of collaborative design processes that involve joint creation, affirming a context in which there is less and less room for individual work and much more for the logic of collective and co-creation. Therefore, the idea that the work is created exclusively by the architect is already understood as a distortion of the complex reality of designing a project, going beyond the technical staff and also adding the community and its users.
Landscaping in Cafes: 10 Projects That Integrate Greenery Into Architecture
Whether it is for a break, relaxation, or even free wifi, coffee shops tend to host a series of situations that involve more than just enjoying a cup of coffee. A quiet and pleasant place, which in addition to everything else offers a good hot drink, is a great attraction for those looking for a coffee shop to spend a few hours.
In this sense, a landscape project that integrates greenery into these environments can significantly increase the comfort of customers, by easing temperatures and offering a barrier against atmospheric, noise and visual pollution. In addition, after the restrictions imposed by the Covid-19 pandemic, open spaces, with natural ventilation and gardens became priorities for many projects, including coffee shops.
Copenhagen Selects JAJA Architects’ Proposal for New Climate-Friendly Metro Stations
JAJA Architects won the competition organized by Metroselskabet, Denmark, to develop resource-efficient and climate-friendly metro stations. The winning team takes a comprehensive and holistic approach, looking at both material-optimized and sustainable design solutions and the character of the journey that passengers take to reach their destination. The proposal is centered around three core elements: Materials, Mobility Hub and Climate Campaign. While aiming to reduce CO2 emissions, the team also seeks to create an enjoyable and easy-to-navigate space for the many daily passengers. Snøhetta, 3XN/GXN, and Effekt also participated in the competition.
Workers Begin Dismantling Qatar’s Stadium 974, the First Temporary World Cup Stadium
Reports show that authorities have begun dismantling Stadium 974 after it hosted seven matches during FIFA World Cup, with six group games and one Round of 16 knockout matches. It was also the only stadium built for the World Cup without air conditioning, so it only hosted evening matches. According to the BBC, construction workers moved on the site on 9 December to “take the stadium out of tournament mode.” The structure was designed to be the first FIFA-compliant stadium that can be fully dismantled and re-purposed after the tournament ends. While Qatar called this a “beacon of sustainability,” experts warn that the real sustainability of the scheme depends on several factors, including when and where the stadium will be reused.
The Future of Mobility Has Two Wheels: Copenhagen’s Bike-Friendly Architecture
Ambitious technologists have claimed for decades that self-driving cars are the future. Yet, looking at recent years, the biggest revolution has come from vehicles on two wheels, not four. Fueled by the pandemic, increased oil prices, climate change and the desire for healthier lifestyles, we are now living in the midst of a bicycle renaissance. But to understand how we got here, it is crucial to look back. When the automobile became more widespread in the early 1900s, it quickly became a symbol of progress along with all it entailed: speed, privatisation and segregation. Adopting a car-centric approach, urban planners had to reorganise entire cities to separate traffic. Cars took over public spaces that used to host dynamic city life and parking lots, highways and gas stations became common landscapes. Pedestrians that once ruled the streets were herded into sidewalks and children relegated to fenced playgrounds. Ironically, cities were being designed for cars (not humans).
