What is urban density, and what are its advantages and disadvantages?

Subscriber Access | 

An increasing number of people live in urban areas. UN-Habitat's World Cities Report 2022 reveals that this share rose from 25% in 1950 to over 50% in 2020, with projections indicating it will reach 58% over the next five decades. The survey also indicates that by 2070, the number of municipalities in low-income countries will increase by 76%, while in high- and lower-middle-income nations, this growth will hover around 20%. Furthermore, the study notes that this scenario highlights the urgent need for cities to be designed and managed so that future growth does not overwhelm existing infrastructure, open spaces, and services—which would lead to unsustainable sprawl.

Eastman Mansion and the Underground History of Limache

In 2016, in the commune of Limache in Chile's Valparaíso region, tunnels connecting to various parts of the city—including the CCU brewery—were discovered beneath a hatch in the gardens of the landmark Eastman Mansion. Prompted by uncertainty over why they were built, an investigation was launched, with the findings behind the project's origins finally revealed in 2021.

The Future of Architecture: Imagining a World Where Buildings are Constructed from Living Materials

Can you imagine a world in which the built environment around us is 3D printed from living materials? That buildings will germinate, bloom, wither, produce new kinds of material, and eventually return back to the soil? To Grow a Building is a performative lab space that 3D prints - in real time - a live structure. The project presents a new approach to integrating flora into the design process, by developing a novel material for 3D printing, through which seeding is an inseparable part of the fabrication process. To Grow a Building is a gate into a future world in which there are people who build buildings, and there are people who grow them.

Senate approves legal framework for offshore energy production

On Wednesday, August 17, the Senate Infrastructure Services Committee approved a bill establishing a regulatory framework for offshore energy generation—including wind, solar, or tidal—in Brazil's open seas, lagoons, and other bodies of water. The Bill (PL) 576/2021 regulates authorizations for harnessing offshore energy potential. Authored by Senator Jean Paul Prates (PT-RN), the bill was approved in a final vote by the committee and will now proceed to the Chamber of Deputies for review.

Andenes and Terraces: Natural Infrastructures and Andean Landscapes

Subscriber Access | 

In sloped topographies, factors such as rainfall and excess water promote surface runoff, triggering a series of impacts that lead to the loss of soil, water, nutrients, and seeds, consequently reducing agricultural productivity (Posthumus, 2005). In Andean mountain environments, this is compounded by water scarcity and variability, alongside the challenges of water retention (Canziani, 2007). To address these challenges, territorial transformations and modifications known as terraces and andenes emerged, representing some of the oldest infrastructural practices for soil and hydrological conservation and management. Their physical presence, productive use, and cultural relevance remain vital in many parts of the world today.

The Story Behind Frankfurt's New Old Town and how the Community Revived its Medieval Identity

Subscriber Access | 

The architectural identity and urban fabric of the old city of Frankfurt has grown organically over centuries. Shops, bars, and craftsmen's workshops have always attracted a lot of visitors to the area between the Cathedral, or "Dom" in German, and the Römer, the main square in the center of Frankfurt. Historically, the area included buildings of many different styles, such as Gothic, Renaissance, Baroque and Classical architecture, which most locals only knew about from black and white photographs, the town’s famous miniature model in the historic museum, or stories passed down through generations.

However, the quarter’s picturesque buildings and alleyways, were almost entirely destroyed during the Second World War, but the collaborative work of the community and local authorities have made it seem as though time before the war stood still. The entire quarter was reconstructed exactly as its original plans, bringing Frankfurt’s medieval history back to life and creating what is now known as the Neue Alstadt, a project considered by some to be controversial.

Ennead Architects Unveils Mass Timber Chilean-Argentine Border Station Inspired by Local Topography and Culture

Ennead Architects has revealed its competition design entry for the Chilean-Argentine border complex along the Cardenal Antonio Samoré Pass, one of the most heavily-trafficked mountain passes through the southern Andes and between the two countries. Dubbed Samoré, the project is designed to serve as a welcoming station and refuge for travelers, complementing the Patagonian tradition of remote mountain shelters that are commonly found across the southern Andes.

Cities from US and Europe Seek to Ban Fossil Fuels in New Buildings

Boston is the latest city to announce a city-wide plan that, if passed, would eliminate the use of fossil fuels in new constructions and major renovation projects. This measure expands upon the commitment to enact climate action and make Boston a Green New Deal city. Other US cities like New York, Los Angeles, San Jose, Seattle, and Berkeley have all imposed similar measures in recent years. Seven European cities - Bilbao, Bratislava, Dublin, Munich, Rotterdam, Vienna, and Winterthur - have also developed a project to phase out fossil fuel from urban heating and cooling.

Forests for water: a nature-based solution to tackle water crises

Subscriber Access | 

What if policymakers, when deciding how to allocate public investments, looked beyond massive concrete structures and also turned their attention to forests?

Viewing the conservation, restoration, and management of native vegetation—in other words, nature-based solutions—as viable investment alternatives to improve urban infrastructure is an innovative approach that can yield major benefits for society. A prime example lies in the water treatment and supply sector: forests can play such a crucial role that they can be considered a form of natural infrastructure.

Can Public Space be Created in the Metaverse?

Subscriber Access | 

The metaverse promises to revolutionize our way of life. By integrating immersive technologies like virtual and augmented reality (VR and AR), it hopes to add another layer to the way we experience everyday life. It is suggested that the metaverse will create virtual spaces where people can meet and share experiences regardless of geographical constraints. The possibilities seem endless: exchanging knowledge, encouraging professional collaboration, developing and democratizing art, education, culture, and even enabling political engagement. Social interactions are at the core of the idea of a metaverse. This raises the question: how can the new, virtual spaces acquire the properties of public spaces?
