Ventilation serves two main purposes in a room: first, to remove pollutants and provide clean air; second, to meet the metabolic needs of the occupants, providing pleasant temperatures (weather permitting). It is well known that environments with inadequate ventilation can bring serious harm to the health of the occupants and, especially in hot climates, thermal discomfort. A Harvard University study demonstrated that in buildings with good ventilation and better air quality (with lower rates of carbon dioxide), occupants showed better performance of cognitive functions, faster responses to extreme situations, and better reasoning in strategic activities.

Hemp is one of the oldest crops domesticated by humans. With its wide variety of uses and applications, it’s easy to understand why it’s been a desirable product throughout history. Hemp seeds and flowers are used in health foods, medicines, and organic beauty products; the fibers and stalks of the hemp plant are used in clothing, paper, and biofuel. Today even a waste product of hemp fiber processing, so-called hemp shives, is being utilized to create sustainable building materials like hempcrete. 

Hempcrete is a bio-aggregate concrete, where the hemp shives - small pieces of wood from the stalk of the plant - are mixed with either a lime or mud cement to create a durable, eco-friendly building material. Hempcrete is lightweight and non-structural, but can instead be integrated with traditional building construction systems. Similar to traditional concrete, it can be either cast-in-place or prefabricated into building components like blocks or sheets. 

Just before the global lockdowns began in response to the spread of the widely discussed COVID-19, we met with Saint Gobain experts at their new headquarters in Paris to discuss an extensive investigation conducted in 2019, with the aim of understanding the transformations that architecture and construction have experienced in recent years. After an interesting exchange of ideas, we chose the most relevant topics to be analyzed in depth by our team of editors, resulting in a series of articles that combined the trends identified with the unexpected events that occurred during 2020, connecting them directly to architectural design.

When creating a contemporary atmosphere for living, many factors come into play. The surrounding environment, its climate, use of materials, spatial organization, and the attention to detail in both the interior and exterior design, all impact the quality of the design as a whole.

Le Corbusier's fascination with the automobile is evident in the architect's various photographic records of him posing proudly next to a car in front of his architectural work. According to the Franco-Swiss architect, in addition to enabling more efficient and economical construction, the industrialization of architecture could form the basis of improved aesthetic results in the same way the modern car chassis supports the creative and modern design of the automobile body. Yet, while vehicles have experienced impressive changes since the 1930s, it can be said that architecture has been slower to adopt the advances of other industries.

The Shing Mun River in Sha Tin, a residential town in Hong Kong, has struggled with plastic waste pollution for years. Household waste that is not properly recycled will either end up in landfills or floating in the river. In 2018 almost 17 million plastic items, or 40,000 items daily, were found to be drained into the ocean via the Shing Mun River, mostly being food packaging, cutleries, and household plastic bottles. This quantity of plastic pollution in the river and surrounding environment could eventually jeopardize the natural ecosystem irreversibly.

The height of the ceiling of a space heavily influences our perception of it. Generally, local building codes regulate the minimum dimensions for ceiling height, which are calculated to ensure adequate quality of life in the environment. But the exact height of the ceilings is often defined by the dimensions of other materials that make up the building, the height of the constitutive slabs, or even by rounding the dimensions of the stair steps. It is common, with the densification of cities aimed at increasing profitability, for entrepreneurs to design with minimum ceiling heights in houses and offices, reducing construction costs. On the other hand, in older structures, more generous ceilings can be observed, which generally enable a greater degree of design freedom. But how can architects make the most of these spaces?

Industrial buildings are among the best examples of Louis Sullivan's famous phrase "form follows function." Generally, they are functional, efficient buildings, quick to build and unornamented. That is why, when we study the industrial heritage of different cities and countries, we are able to understand local materials, technologies, and traditional construction methods of the time. England's red brick factories come to mind, as well as the roof lanterns used to provide natural light to factories and other typical construction elements. Metallic and precast concrete structures are currently the most commonly used due to a combination of construction efficiency, cost, the possibility of expansive spans, and the unawareness of the benefits of other materials, such as wood. Often, these industrial warehouses are also characterized by being cold and impersonal, in addition to having a considerable carbon footprint. But Canada's experience in recent years is noteworthy, where there have been an increasing number of wooden buildings constructed for industrial programs.

Metaphorically, building bridges equates to creating new opportunities, connections, and paths. The first bridges likely formed naturally with logs falling across rivers and natural depressions, though humans have also been building rudimentary structures to overcome obstacles since prehistory. Today, technological advances have made it possible to erect bridges that are both impressive and sculptural, playing a key role in transportation and connectivity. Usually needing to overcome large spans, with few points of support, bridges can be quite difficult to structure. But when is the bridge more than a connection between two points, instead resembling a building with a complex program? How can these 'bridge houses' be structured?

Tall timber buildings are on the rise. Design teams around the world are taking advantage of ever-evolving mass timber technologies, resulting in taller and taller structures. Building off our recent article exploring the future of high-rise buildings, we’re taking a deeper dive into new emerging timber technologies and the advantages of building taller with wood. This tutorial explores how to make tall timber structures a reality.
