Bricks are part of the collective imagination when thinking about construction. These are elementary, ubiquitous, modular, light, and reliable materials for erecting buildings. However, traditional ceramic block manufacturing relies on burning clay in kilns at high temperatures, often powered by non-renewable fossil fuels such as coal or natural gas. Furthermore, the transportation process significantly increases its environmental footprint, as the materials are heavy and bulky. In light of this, there is a growing interest in alternative construction materials that offer a lower environmental impact and greater sustainability. Soil cement bricks –or Compressed Stabilized Earth Blocks– are a good example of an existing alternative, as they have a smaller environmental footprint due to their use of local raw materials and the elimination of the burning process, while maintaining many of the intrinsic qualities of traditional bricks.
On the 3rd of February, this year's Lagos Biennial opened at the Tafawa Balewa Square, Lagos, an emblematic venue that was once the site of Nigerian independence celebrations in 1960. As the 4th edition of the art fair, it continues with its objective of using art to activate historic landmarks that have lost significance either through functional use or symbolic meaning to the residents of the former capital city.
The previous editions of the Biennial have explored various aspects of the city's architecture, its symbolic significance, political implications, sovereignty, ownership, notions of belonging, and its relationship with the public. This year, the theme of "Refuge" at the Tafawa Balewa Square takes this exploration even further. Curators Kathryn Weir and Folakunle Oshun highlight that this theme prompts the square to address the concept of a nation-state. It also brings together artists and architects from different disciplines to explore alternative approaches to constructing renewable communities and promoting climate justice.
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.

For a long time, sustainability in the architectural field was synonymous with technology. Efficiency was directly linked to innovative technological devices that adorned buildings with gadgets. Nowadays, however, sustainability increasingly encompasses different strategies that also involve acknowledging vernacular techniques and local materials as crucial for creating sustainable and carbon-neutral buildings.
Nevertheless, regardless of the technique or materials employed, the common denominator is the pursuit of reducing the carbon footprint of our architecture, which demands changes in how buildings are conceived, constructed, and operated. In other words, whether returning to vernacular methods or utilizing cutting-edge applications, these strategies aim to reach the same destination and, therefore, are equally valid despite being vastly different.
A few days before the end of November, Gramado, a city known as one of the most sought-after tourist destinations in southern Brazil, grabbed the attention of national and international media. Unfortunately, it wasn't due to its film festival or the traditional lavish Christmas festivities. The city, already suffering from weeks of persistent rain, witnessed the emergence of massive geological rifts tearing through its streets, creating a post-apocalyptic movie-like scenario.
The imminent danger of ground movement alerted the population and the authorities, who promptly evacuated the buildings on the hills of the condemned neighborhood. This course of action proved entirely effective and responsible, as one of the buildings within the designated area did indeed collapse three days after the evacuation. However, it is worth noting a detail: the affected neighborhood consisted of upscale residences and luxury hotels and inns, which raises a question: would the efforts have been the same if the situation occurred in lower-income peripheral neighborhoods?
The global housing crisis generates a wide range of challenges, from those who are in situations of homelessness, to the realities of millions who face unaffordable housing conditions, overcrowding, and excessively high rents. Tackling this involves political will, the union of the state and private companies, and innovative solutions that prioritize accessibility, sustainability, and government mechanisms that enable a functioning system. Amongst all of these factors though, one thing is certain: we need to build massively in the future to improve the housing situation. The implementation of efficient construction methods, such as prefabrication and modular construction, can speed up the creation of affordable housing units, reducing construction costs and timeframes. Adopting green building practices, such as using recycled materials and designing energy-efficient structures, not only contributes to sustainability but minimizes long-term operating expenses for residents.
The American Institute of Architects has announced David Lake and Ted Flato, the founders of Texas-based firm Lake|Flato Architects, as the winners of the 2024 AIA Gold Medal. The pair was selected by the jury for their ability to make "sustainability exciting in a way few other architects have accomplished." Founded in San Antonia in 1984, their office set out to make environmentally conscientious design both accessible and exciting, by finding ways to strengthen he bond between humans and nature.

In the rapidly evolving landscape of the 21st century, cities have emerged as models of innovation in terms of sustainable development goals. Cities creatively address pressing urban challenges, including density, transportation, housing, and resilience. They hold the potential to pioneer a comprehensive climate agenda, serving as laboratories for sustainable initiatives, cross-sectoral innovations and community-oriented strategies. Cities act as catalysts for revolutions, implementing impactful solutions that can be applied worldwide.
Moving towards modernity implies questioning established concepts. Today, we are witnessing several projects and approaches in architecture that explore alternatives to energy-intensive building systems, materials, and technologies commonly used in today's construction. These projects, far from adopting approaches that reject technology, seek to promote conscious architectural practices. They aim to go back to basics through passive strategies, using natural materials and a contextual understanding to develop sustainable architecture.
To boost sustainable architecture, it is crucial to have building models and materials that become recognizable icons in their immediate context, thus setting a precedent for the development of future proposals. One such example can be found in Spain, with the "Impulso Verde" project carried out in the city of Lugo which stands out for its construction model based on passive strategies and regional materials. In this project, using natural slate as cladding for the ventilated facade system and employing local resources in the structure was essential for the building's ecological footprint. Additionally, these elements strengthen the building's identity by connecting it to the surrounding landscape.

MVRDV and Orange Architects collaborate on the NUVO project, a new mixed-use complex to be built in Ukraine’s capital, the team of architects has revealed their design for three of the buildings that will become part of NOVO. Commissioned by Kovalska, the project is now restarting after work was put on hold due to the active conflict in Ukraine. The two firms are collaborating to refine the master plan initiated by APA Wojcehowski Architects.
Including sustainable strategies in architectural projects is not just a trend, it is a necessity. Each day we become more aware of the importance of responsibly managing natural resources and understanding the environmental factors involved in designing a project.
Solar energy is one of the most commonly employed strategies in residential architecture, both active and passive. Many countries around the world offer incentives to encourage the use of solar systems, and the benefits of installing these systems can be seen in a short period of time, with a reduction of up to 95% in the monthly energy expenses, which makes this strategy one of the most attractive of all sustainable solutions. Furthermore, the average lifespan of a solar panel is 25 years, operating entirely on its own and requiring only basic cleaning once a year.
In a bid to explore new materials and methods for more sustainable construction, Henning Larsen opens the “Changing our Footprint” exhibition at the Danish Architecture Center in Copenhagen. The initiative, open from November 17, 2023, until March 3, 2024, aims to showcase ideas for more climate-friendly architecture and to start conversations on architecture and construction’s role in mitigating the effects of climate change.
