Let us return to the first architecture class on structures and the classification of structural efforts. In most structures, whether natural or man-made, compression forces are the primary actors. These are efforts undertaken with equal and opposing loads, applied in the interior of the structure, which tend towards the shortening of the piece in one direction - or compressing it, as the name indicates. It is not difficult to find examples of this: for example, a stone wall or a wooden log can resist the weight of a covering through internal compression efforts that are inherent to each material. Tension efforts, on the other hand, tend to lengthen components in the direction of the applied force of action. Steel, for example, is a material with good tensile strength. It is used in reinforced concrete precisely in the parts where the piece is in traction. But it is also possible for a structure to only have tensile parts, as is the case of membrane, tensioned, or tension structures, which consist of surfaces pulled by the action of cables or ropes in which the masts absorb compression efforts.

Metal Façades: How to Unite Aesthetics, Performance and Safety?
Metal façades give buildings an air of sophistication and modernity. They also bring a cleanness to the façade, due to their precise fabrication and well-resolved connections between other materials and building elements. There are currently multiple product options available for coatings, offering extensive colour options, including metallics, with different levels of durability (natural aging and corrosion). One of the main issues when approaching metal façades is the risk of corrosion, which can create points of weakness in the material and interfere with the aesthetics of the building. So, with this in mind, what do architects need to focus on to ensure that building envelopes age gracefully, while maintaining aesthetics and performance over time?
Versatile Lighting Toolkit: Endless Possibilities for Interiors
Artificial lighting plays an essential role in spatial quality. Badly thought-out lights can disrupt an architecture project and even bring harmful effects to occupants' health; while a well-balanced luminotechnic project can highlight positive aspects of the surroundings and make it much more enjoyable. Generally, however, projects tend to be too rigid and not in-tune with the flexibility of contemporary spaces. In addition, a badly made lighting decision can be complex and expensive to rectify. For example, electrical points in slabs, linings or walls are not easily modified if the distribution of a space is changed. At most, when this is resolved with hanging or free-standing lamps, we end up having to deal with bothersome electrical wires throughout the space.
What Materials Can Be Used for Façade Cladding?
Cladding systems have important functions in buildings. They can confer thermal insulation, protect internal spaces from the weather and–just as important–give the building a "face", improving its appearance and clearly identifying the element of design. "Cladding" refers to the components that are linked to the structure of a building to form non-structural external surfaces. While in the past wooden cladding was the only option, there are currently multiple possibilities of materials, colors, weights, textures, anchoring systems, and many other variables available. Below, we outline some of the main materials used for façade cladding, and the projects that use them in a remarkable way:
A Billing and Payment Solution Made Specifically for Architects
Pricing architectural project work is a complex issue that is not usually addressed during one's formative school years, and it usually takes time for professionals to develop a good system that works for them and their clients. Issues such as scope of work, hours worked, project area and project complexity will influence the final cost of a job. In addition, another thing that can keep project professionals awake at night is how to charge clients in a way that is sustainable for the business and comfortable for future users of the designed space.
Interior Design in Education: The Role of Natural Light in Kindergartens
Our environment influences how we feel; we have all experienced this. For students, it is easier to study in a bright place, artists look for inspiring atmospheres, and our mood can improve with the right color scheme. These aspects are also important for kindergartens, daycare centers and schools, because a child-friendly design can stimulate the curiosity and imagination of children, so that they learn in a playful way. The design of a room supports the learning and creativity of children. Daylight systems, for example, flood rooms with light, making them appear larger and friendlier.
Daylight Helps Transform a Once Victorian Prison into a Luxurious Hotel
Commercial building refurbishment projects present architects with design challenges. Transforming 18th century Bodmin Jail into a modern hotel meant an acknowledgement of restrictions in relation to the building’s infrastructure. Listed buildings often have construction regulations to preserve historic and architectural interests, impacting thermal comfort and how daylight is introduced to transform building spaces.
These design challenges can make architectural planning appear more complex, particularly when a building is being repurposed. Common challenges include sourcing materials to replicate or meet existing infrastructures. The adaption of floor plans, consideration of user comfort and introduction of technology in planning phases, also influence contemporary design. The Bodmin Jail Hotel required skylight installations that could work within an existing and iconic sloping roof.
Integrating Shade and Protection Devices into Open Spaces
Comfortable outdoor spaces are more desirable than ever. Over the past couple of years, people have been spending more time at home, connecting with nature from the relative comfort of covered balconies, patios, and pergolas. But even with pleasant views, cooling breezes, and the warmth of the sun, covered outdoor spaces can be uncomfortable. Temperature variations, glare, rain, and wind quickly create an unpleasant experience. In warmer climates, insects can be an additional a nightmare.
Five Decades of SCI-Arc Celebrated with a Year of Public Programs
SCI-Arc (Southern California Institute of Architecture) was created in 1972 and based on the concept of a "college without walls". Its original name was New School, which symbolized a paradigm shift in teaching architecture, focusing on a horizontal relationship between teachers and students and on experimentation, making it one of the few independent architecture schools in the world. In 2022, the institution turns 50 and has planned a calendar full of events and projects to take place throughout the year.
Francis Kéré: "I Draw on Paper, but I Prefer to Draw on the Ground"
"I Draw on Paper, but I Prefer to Draw on the Ground". This phrase caught my eye during Diébédo Francis Kéré's speech at the AAICO (Architecture and Art International Congress), which took place in Porto, Portugal from September 3 to 8, 2018. After being introduced by none other than Eduardo Souto de Moura, Kéré began his speech with the simplicity and humility that guides his work. His best-known works were built in remote places, where materials are scarce and the workforce is of the residents themselves, using local resources and techniques.
Durability and Sustainability Can Be Synonymous: The Example of Bricks
It is crucial to consider the future environmental impact of everything we create. Climate change remains high on the global agenda, and every industry must take part in the goal of reaching Net Zero. One of the more challenging industries concerns construction, which plays a vital role in the process of decarbonization and is constantly encountered with challenges to become greener. Therefore, it demands innovative techniques and development of data to find new and sustainable processes. One solution is to introduce and design both cleaner and more efficient materials. Bricks are a good example, as they can be used in building constructions to ensure a circular process and minimize carbon emissions, being an extremely durable material that can be produced with more sustainable techniques.
Varnishes, Stains, Oils, Waxes: What are the Most Suitable Finishes for Wood?
In recent years, much attention has been given to timber constructions. Being a sustainable and renewable material, which captures a huge amount of carbon during its growth, the innovations related to this material have allowed for increasingly higher constructions. However, when we talk about wood we approach an immense variety of species, with different strengths, nuances, potentials, limitations and recommended uses. While there are extremely hard and heavy woods, with strengths comparable to concrete, there are other soft and soft woods that are suitable for other purposes.
Designing Virtuous Buildings: 6 Projects that Combine Sustainability and Performance
The clothes used by nomadic peoples in the desert (Bedouins, Berbers, Tuareg, among others) are usually dark, long and made of heavy fabric. Contrary to common sense, which would recommend light, pale and short clothes for a hot climate; heavy and loose clothing favors air convection, creating a constant flow of air along the body, providing thermal comfort in arid climates. For buildings, the analogy works. When approaching energy efficiency and project performance, we will inevitably talk about its envelope, among other aspects of the project. A successful solution in one location, will not always be efficient in another.
During the last 2 years we have created a series of articles on wellness and sustainability focused on the construction industry. But how do projects, according to their demands and context, apply the solutions to make them, in fact, efficient and perform well?
Architecture and Technology Can Promote Greater Autonomy for People with Disabilities
A corridor that is too narrow, a poorly located switch or a simple unevenness can go completely unnoticed to many, but they can also be insurmountable barriers for someone with a disability. We all have a family member or acquaintance with mobility difficulties and, possibly, we might also experience them at some point in our lives. Architecture has the power to create truly inclusive spaces so that people with disabilities can have the autonomy to perform all necessary daily tasks, without needing the help of others. Integrated into architecture, technology can play an important role in this context, making the spaces in which we live even more accessible to everyone.
What Building Materials Can Be Harmful to Our Health?
In each of our nostrils, two types of nerves play an essential role in our health. The olfactory and trigeminal nerves capture odors and send information to the brain, more specifically to the olfactory bulb, for interpretation. In turn, this communicates with the cortex, responsible for the conscious perception of odors, but also with the limbic system, which controls mood and unconscious emotions. This is the body's defense against bad smells or irritating or strong odors, creating aversion to those that could harm us in some way.
But not all pollutants can be detected through this sophisticated system, and they have an intrinsic ability to positively or negatively influence our health. In fact, research has shown that air quality can be quite poor and even worrying in many indoor environments, where we spend about 90% of our lives. This is usually caused by inadequate ventilation of the space, external pollution, and biological contaminants; but mainly chemical contaminants from internal sources. That is, the building materials used in space. Therefore, there are some products that should be avoided whenever possible.
Using BIM to Deliver Low-Carbon Wood Buildings
In the original design for the Sydney Opera House, Jørn Utzon envisioned the shells supported by precast concrete ribs under a reinforced concrete structure, which turned out to be prohibitively expensive. As one of the first projects to use computational calculations, the final solution - reached jointly between the architect and the structural engineer - consisted of a precast ribbed system of concrete shells created from sections of a sphere. At the Guggenheim Museum in Bilbao, the project team used CATIA software (typically used by the aerospace industry) to model and materialize the complex curvilinear shapes of the titanium-coated volume designed by Frank Gehry. Challenging projects tend to spark the creativity of those involved to make them possible, but there are constructive systems that interact well with existing technologies. This is the case, for example, with engineered wood and the BIM system. When used simultaneously, they usually achieve highly efficient and sustainable projects.
