A study conducted in Australia has proven that green roofs help increase the efficiency of solar panels. Essentially, the panels perform better when they do not get too hot.
The study analyzed two identical office buildings located side-by-side in Sydney. One was equipped with a conventional photovoltaic solar system, while the other featured solar panels surrounded by vegetation. Both systems were monitored over an eight-month period spanning both summer and winter.
Jane's Walk is part of the Jane's Walk initiative, an annual festival that aims to honor activist and urbanist Jane Jacobs by organizing city walks around the world to reclaim streets as public spaces for coexistence and community gathering. This text on Jane Jacobs Walks, written by Susana Jiménez, is part of a series of guides made available by the project "La Aventura de Aprender" (The Adventure of Learning), conceived and coordinated by Antonio Lafuente and Patricia Horrillo.
Jiménez, a musician, philosopher, and PhD in art history, has been promoting and coordinating this experience in Madrid since 2010. Every first weekend of May, groups of neighbors and people interested in urban planning and neighborhood networks organize open assemblies to host this activity. It consists of walking through the streets of different proposed neighborhoods and discussing what is happening in them, whether regarding urban planning, housing, local events, or reclaiming collective memory.
In Accra, the capital of Ghana, Owusu, his wife, and their four children share a house with five other tenants and their families in the Tantra Hills neighborhood. The house has one bathroom and electricity, but the costs of both are excessively high. Because it is not connected to the municipal water grid, Owusu must buy water from vendors who charge high prices. The electricity bill, around $50 per month, is higher than his rent of $33. With a monthly income of $175, Owusu lives in constant fear of eviction if rent, water, or electricity prices rise.
In addition, Owusu's neighborhood lacks easy access to public transit. The nearest bus stop is about a kilometer away, and he typically waits up to 30 minutes for a bus. His commute to work at a gas station takes around two hours, even without traffic. From Monday to Saturday, he leaves home at 4:30 AM to beat the rush hour.
Imagine housing strangers in your backyard. Some time ago, the idea might have sounded absurd, but the boom in the tourism market (before the pandemic) made alternative lodging options, such as CouchSurfing and Airbnb, highly sought-after. In Seattle, Washington's largest city, a project is seeking volunteers willing to open up their backyards to install tiny shelters. Unlike programs aimed at young travelers, this initiative has a social purpose: the goal is for people to actually live in these spaces.
The *Block Project* was conceived by architect Rex Hohlbein after he opened up his own property to house a homeless artist. For Hohlbein, the community must get involved if it wants to solve the housing crisis affecting major cities. Seattle ranks among the 100 most expensive cities in the world to live and work, according to Mercer's 2021 global survey.
The Tomie Ohtake Institute and AkzoNobel present the 13 projects selected for the eighth edition of the Tomie Ohtake Institute AkzoNobel Architecture Prize. The selection was made by a jury comprising architects Ariadne Moraes, Carlos Alberto Maciel, Cintia Lins, Diego Mauro, and Tainá de Paula.
An estimated one billion urban residents live in informal settlements. These settlements have grown in response to rapid population growth and a lack of affordable, higher-quality alternatives. They are "informal" because they do not comply with government regulations. Historically, the official response was typically intimidation or, if they were not highly visible, neglect.
In this episode of the Caos Planejado podcast, architect, professor, and researcher Ester Carro shares her experience leading the Fazendinhando movement, a social urbanism project focused on territorial, cultural, and social transformation in the Jardim Colombo neighborhood, in São Paulo's West Zone.
Cora Coletivo, a transdisciplinary Brazilian group, developed a project in the city of Dongguan, China, for the Urban Greenhouse Challenge II (UGC2) competition. The proposal for an iconic timber-structured vertical farm houses culture, leisure, and the entire food production and distribution chain. In addition, the site features landscape design in its open spaces and an Agroforestry System (SAF) for food production.
Architecture students from Mackenzie Presbyterian University in São Paulo have won the 14th ALACERO Steel Design Competition for Architecture Students 2021, surpassing competitors from countries such as Argentina, Chile, Mexico, Ecuador, and the Dominican Republic. The competition aimed to promote architectural concepts that utilize steel as their primary material.
No País dos Arquitectos is a podcast created by Sara Nunes, who is also behind the architectural film production company Building Pictures, which aims to profile the professionals, projects, and stories behind leading contemporary Portuguese architecture. With just over 10 million inhabitants, Portugal is a fascinating country when it comes to this professional field, and its architectural output punches far above its demographic or territorial scale.
In this episode, Sara talks with architect Paulo Martins Barata, from the firm PROMONTORIO, about the design of Casa da Volta, located in Grândola, Portugal. Listen to the interview and read the transcript of the conversation below:
A large floating solar farm has begun operations in Thailand. Solar cells installed on the water's surface harness sunlight during the day, while three turbines convert hydropower at night.
The system combines two types of renewable electricity generation at the Sirindhorn Reservoir in Ubon Ratchathani province, located about 660 kilometers from the capital, Bangkok. A total of 145,000 solar panels have been installed. The 45 MW of peak power produced by the project complements existing dam operations, which can generate an additional 36 MW and supply electricity to three provinces in eastern Thailand.
There are many ways to introduce more greenery into our homes and cities, such as bird-attracting trees, vegetable gardens, and medicinal plants. However, certain outdoor zones must serve as pathways, recreational areas, parking spaces, or other functions. For these areas, permeable paving offers an excellent alternative.
The Colombian Society of Architects (SCA) has officially launched the 37th Colombian Congress of Architecture and Urbanism, which will focus on public space as its central theme. This focus comes in response to the pandemic lockdowns experienced both nationally and globally. The event will feature 103 speakers and 60 academic sessions across various formats, offering approximately 45 hours of highly relevant academic, productive, and regulatory content for the industry.
Through immense Greek columns, the door centered under the pediment invites one to enter either a temple or a home. The sense of smallness is undeniable. From north to south, this is a recurring scene: no upper-middle-class neighborhood escapes a neoclassical building.
At a time of profound social, spatial, and cultural change, the 12th edition of the Arquiteturas Film Festival invites reflection on how physical and symbolic borders shape the built environment, influencing daily life and collective dynamics. What role do architecture and urban thinking play in understanding this changing world?
Since the cultural center INSTITUTO took over its organization in 2021, the festival has established itself as a critical platform connecting cinema, architecture, and spatial practices to discuss urgent issues. In recent years, it has addressed migration, ecological crises, decolonization, and new ways of living. In 2025, the focus turns to the 'border' in its multiple dimensions.
Over the centuries, kitchens have undergone an interesting transformation that has dictated both their use—once frequented only by staff, today an essential social hub—and their size—shrinking from the largest room in the house to one of the smallest. Yet, regardless of size, the kitchen increasingly represents the heart of the home. An essential space, it now transcends the simple act of preparing food, becoming a place associated with leisure and togetherness. Consequently, this space must meet a series of specific demands, balancing functionality and efficiency with comfort and well-being.
A vast majority of construction in Brazil occurs without the involvement of architectural professionals. Yet, thousands of architects graduate across the country every year. At the same time, Brazil has a rich building culture, expressed through people building their own homes and the traditional knowledge of communities shaping daily life.
Doesn't it seem obvious that those who build should stand alongside those who design to shape reality together? This is the proposal behind Canteiro Móvel.
November 19 marks Women's Entrepreneurship Day, prompting a reflection on the challenges of entrepreneurship as a woman.
In 2019, the Brazilian Institute of Quality and Productivity released its most recent report on Entrepreneurship in Brazil, based on the Global Entrepreneurship Monitor (GEM), a worldwide research program that assesses entrepreneurship levels across countries. In this report, which predates the COVID-19 pandemic, 88.4% of respondents stated that one of their primary motivations for starting a new business was 'to make a living because jobs are scarce.' In Brazil, micro-enterprises have gained significant ground as alternative employment, driven both by rising unemployment rates and the deregulation of labor laws and subsequent increase in 'outsourcing.'
The Tecelagem Parahyba and Fazenda Santana do Rio Abaixo complex in São José dos Campos, São Paulo, is the newest monument to be permanently listed as Brazilian Cultural Heritage. The unanimous decision was made on the 10th of this month during the 98th Meeting of the Cultural Heritage Advisory Council, a body of the National Institute of Historic and Artistic Heritage (Iphan). The complex had already been provisionally listed by the agency and is now permanently protected.
Estúdio Gustavo Utrabo was one of the winners of the LafargeHolcim Awards for sustainability, receiving the Silver Award in Latin America for the "Community Processing Facility in the Amazon" project, a Brazil nut processing building located in the village of São Francisco, along the banks of the Iratapuru River in the Amazon Basin.
The factory's modernization project aims to offer productive, cultural, and economic opportunities for the local community. The building is the result of a collaborative process between the architects, the local community, and Natura, a cosmetics company that uses ingredients extracted from the nut in its products and was the project's primary financial backer.
The Municipality of Flores da Cunha (RS), in partnership with the Institute of Architects of Brazil – Rio Grande do Sul Department (IAB RS) and supported by the Council for Architecture and Urbanism of RS (CAU/RS) and the Brazilian Association of Landscape Architects (ABAP), has launched the National Public Competition for Architecture and Urban Design to revitalize Avenida 25 de Julho – one of the city's most important thoroughfares. The competition guidelines are available on the website and the Instagram profiles of IAB RS and the municipal government.
In September of this year, the BANGA Group launched a competition to design the next Cabana de Arte. Open to students and recent architecture graduates in Angola, the competition sought proposals for an exhibition space dedicated to the work of Angolan artist Muamby Wassaky, who explores elements of traditional construction to create sculptures and installations.
First place went to architect Aquitofel Mananga, a recent graduate of the Methodist University of Angola. The winning proposal, titled M.Seque, draws on everyday and suburban references to design the space dedicated to Wassaky's work. Read the project description, submitted by the architect, below.
While closely related, landscaping and gardening are distinct practices that engage with natural, living elements within the built environment. Read on to explore how each of these fields operates.
To reach the designs we know today, bathtubs have taken on countless forms. From Greek public baths and Zen Japanese ofuros to 18th-century cast-iron tubs and sophisticated modern whirlpool systems, these fixtures have been shaped and reinvented over the centuries, securing their place in history. Yet, regardless of culture or era, they have always been associated with spaces of physical and mental purification, allowing for moments of relaxation and introspection.
