Sustainability: The Latest Architecture and News

When capital cities like Paris and Berlin resolved to switch off lighting for public buildings and landmarks in July 2022 in order to save energy in the context of the Russian invasion of Ukraine, the cities created a ripple effect throughout central Europe. Images of dark iconic landmarks swept through the media and allowed politicians a momentary act of environmental demonstration. However, designers have started to question the sustainability of this ad hoc step. Seen from a broader perspective the impression arises that this alleged radical action has been part of a rather media-savvy campaign with small effect in cities at night. Further steps are necessary to reassess urban lighting that may have a major impact on energy saving and sustainability.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
