According to the UN, more than 7000 extreme weather events have been recorded since 2000. Just this year, wildfires raged across Australia and the west coast of the U.S.; Siberia charted record high temperatures, reaching 100 degrees Fahrenheit before Dallas or Houston; and globally, this September was the world’s hottest September on record. As the effects of the climate crisis manifest in these increasingly dire ways, it is the prerogative of the building industry – currently responsible for 39% of global greenhouse gas emissions – to do its part by committing to genuine and sweeping change in its approach to sustainability.
Cooling Interiors Will be the Architectural Challenge of the Future
Meet the Winners of Saint-Gobain’s “Architecture Student Contest”
The 17th edition of the "Architecture Student Contest" has come to an end, with the participation of over 220 universities from 32 countries. This year, the challenge was to transform a district located in Warsaw, Poland in order to revitalize an area located next to Warszawa Wschodnia (Warsaw East). The contest involved the design of a new student residence and housing, as well as a meeting and entertainment center in an old factory building that is classified as a historical heritage site. With the requirement of addressing the space's performance as well as its architectural, environmental and social aspects, the contestants were tasked with a project that positively impacts its users and the planet, with low carbon emissions throughout its life cycle.
The Most Sustainable Building Is the One That Is Already Built: Multi-purpose and Healthy Spaces
Charles Darwin's theory of natural selection sought to explain the origin and survival of species on the planet. In short, it points out that the fittest organism survives and can reproduce itself, perpetuating useful variations for each species in a given place. Adaptation is, therefore, a characteristic that favors the survival of individuals in a context. In the construction world, we could draw some parallels. Could adaptation be an important quality to increase the useful life and efficiency of a building over time, considering the changes and demands of society, as well as technologies and lifestyles?
Replacing Cement with Waste: Embracing the Circular Economy with Polymer Technology
When approaching the process of recycling building materials, there are a number of obstacles to achieving a comprehensive and effective result. First, careless demolition can make the process very complex, as products with different recycling products are often mixed. In addition, not all materials can be efficiently recycled or processed, as many still need expensive or overly complex processes. But the construction industry, being a huge contributor to waste production and greenhouse gas emissions, has also developed multiple new technologies to improve its practices. This is the case of the WOOL2LOOP project, which seeks to solve one of the biggest challenges in applying a circular approach to construction and demolition waste.
Towards Sustainable and Affordable Housing: Is 3D Printing the Future or the Present?
In recent years, the construction industry has faced unprecedented challenges. A lack of skilled workers is driving up costs of labor, there is a global housing shortage, and the effects of climate change around the world are clearer than ever. Therefore, questioning traditional construction methods and pushing the limits of innovation has become a top priority, forcing the industry to implement new technologies as they get on board the digital transformation era. There is one innovation, however, that looks particularly promising: 3D construction printing. Although relatively recent, the technology has already been successfully tested in numerous structures, houses and apartment buildings, reshaping residential construction as we know it. Hence, 3D printing could very well be a viable alternative for more efficient, sustainable and cost-effective mass housing solutions in the near future, positively impacting people’s lives and contributing to greener, healthier cities.
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.
As Climate Becomes Extreme, How to Deal with the Building Envelope?
When talking about energy efficiency in buildings, it is inevitable to mention thermal insulation. We rarely see it in a finished building and, even in the technical drawings, the insulating layer appears as a thin hatch. But this is an element that is of vital importance, as it acts as a barrier to the flow of heat, hindering the exchange of energy between the interior and the exterior, reducing the amount of heat that escapes in winter and the thermal energy that enters in the summer. In a building with good thermal insulation, there is less need for heating to keep the house at a pleasant temperature, also reducing its carbon footprint. Currently, there are many countries that require a minimum level of thermal insulation for buildings, with increasingly strict parameters. But how should this issue be dealt with in the near future, with the worrying climate crisis forecast?
Winners of Saint-Gobain’s International Gypsum Trophy 2021
Today, drywall and gypsum-based systems are currently present in almost all architectural works. These allow you to coat buildings with products that combine, among other attributes, construction ease, fire safety and the possibility of recycling, both in historic structures or completely new constructions. Since 1998, Saint-Gobain - one of the largest distributors of these types of systems - has awarded the projects that best apply them in their solutions, dividing them into 6 categories (Ceilings, Plaster, Plasterboard, Innovation & Sustainability, Residential, and Non-Residential). The submitted projects are meant to demonstrate how the architects managed to ingeniously unite the company's products with innovative solutions to overcome each of the difficulties that the works or contexts impose.
Off-Site Construction is Radically Changing the Rules of Architectural Design
The popularity of pre-designed and pre-fabricated homes is growing, moving much of the construction process from the building site into factories. While countries like Singapore, Australia and the United Kingdom are increasingly adopting modular buildings to meet labor and housing shortages, Nordic countries like Sweden already build 90% of residential single-family houses in prefab wood. Despite the recent surge in interest, off-site building is by no means a new concept. In fact, the construction method has been present throughout history in many attempts to consolidate its use in construction: as far back as A.D 43, the Roman army brought with them prefabricated forts to Britain, while Japan has been building in wood off-site and moving parts in pre-assemblies for at least a thousand years.
Design Guide: 7 Essential Features of a Net Zero Building
Kiribati has a population of around 110,000 people and its economy is centered on fishing and agriculture. Comprised of 33 islands in the Central Pacific, its highest point is only 81 meters above sea level, which makes it potentially the first country that could disappear completely due to global warming and the consequent rise in sea levels. The climate crisis has been a hotly debated topic in recent years and terms such as carbon footprint, greenhouse effect, atmospheric aerosols, and many others, are already staples in our vocabulary. Another widely spoken term is “net zero”, or net zero emission, used as a goal for buildings in different industries and countries. Basically, it means that the energy balance is zero.
How Fire Protection Glass Can Save Lives without Compromising Design
While glass is generally singled out as the weakest part of a building, it is not always true. With technological advances and the continuous innovations of the industry, there is glass that, even while allowing natural light to enter an environment, can protect the building from fire. Beyond fire, there are also other threats such as hot gases, smoke, and heat transmission, which put the safe evacuation of people and the protection of property at risk.
How to Design the Perfect Acoustic Enclosure: Comfort in Flooring, Ceilings, and Walls
As our cities densify and building types become more and more mixed-use, we tend to spend a lot of time in noisy environments. When we think about acoustic comfort, we rarely think of places like restaurants, venues, and big offices; places with a lot of people, machinery, and background noise. The quality of sound can entirely change the experience of people in an interior space, and improving the space's acoustic quality relies on treating all surfaces, from walls to ceilings, and flooring. In this article, we will present a variety of solutions for ceilings, flooring, and walls, their different combinations, and a simple guide of how to apply them correctly in public spaces without compromising the aesthetic of the interior.
Will Refurbishment be the Architectural Specialization of the Future?
The choice of Lacaton & Vassal to receive the 2021 Pritzker Prize was, above all, emblematic. Under the mantra “never demolish, never remove or replace, always add, transform and reuse”, the French duo built a career focused on renovating buildings, providing them with spatial quality, efficiency and new programs. Their approach contrasts with most of the architecture we are used to honoring: iconic, imposing and grandiose works. It also contrasts with the notion of the tabula rasa, of building and rebuilding from scratch, so well represented in Le Corbusier's Ville Radieuse, and which has fascinated architects and urban planners ever since.
Multi Comfort: Meet the Winners of the 16th Edition of the Saint-Gobain International Student Contest
Saint-Gobain has announced the results for the 16th edition of its international Multi Comfort Student Contest. This year, the challenge was to convert the post-industrial area of the Coignet company in Saint-Denis (France) into a space for living, learning, and leisure in the heart of a large green space, respecting both the historical heritage and the needs of sustainable development of modern neighborhoods, in collaboration with the city of Saint-Denis.
