Sustainability: The Latest Architecture and News

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.

It is not difficult to see that ventilation plays a vital role in ensuring adequate air quality and thermal comfort in buildings. We have all felt it. But when we talk about ventilation, a light breeze from the window might come to mind, shifting through our hair and bringing a pleasant aroma and cooling temperature that brings fresh air and comfort. In mild climates, this experience can even be a reality on many days of the year. In harsh climates or polluted spaces, it could be quite different.

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.

Talking to the Louisiana Channel, German architect Anna Heringer outlines the way she works and her multi-disciplinary approach to architectural practice. Growing up in a small town at the Austrian-Bavarian border close to Salzburg - Heringer spent a year living and working in Bangladesh at the age of 19, a place that is now home to a majority of her office's projects. Heringer describes herself as a mix of things in addition to being an architect, describing herself as an activist and a development worker - using her creativity to explore ideas in a variety of forms and media.

The American architect, designer, and futurist Buckminster Fuller once defined the Dymaxion principle as “constructing ever more with ever less weight, time, and ergs per each given level of functional performance.”

There was a time when people appreciated self-contained architecture, in which the building envelope would not function as a moderator between the climate outside and the interior environment but rather as an inert and independent barrier. Countless mechanical devices and electrical ventilation, heating, and cooling equipment. A real machine.

Today, architects are increasingly concerned with the interaction between architecture and the environment in which it is inserted, thus assuming responsibility for the thermal comfort of interior spaces, using design strategies for natural climate control.

Sustainable design in the United States is for many a sort of Rorschach test. The construction industry is either making steady progress toward the ultimate goal of a carbon-free building sector, or it’s moving entirely too slowly, missing key targets as the ecological clock keeps ticking. The perplexing truth to all of this is: both are ostensibly true. In recent decades the industry has become significantly more energy efficient. We’ve added building stock but flattened the energy curve. The cost of renewables continues to drop. But way more is required, much more quickly. At the same time, huge hurdles remain. Without a renewable grid and stringent energy codes, it’s hard to see how we can fully decarbonize the building sector in even 20 years, let alone at the timeline suggested by increasingly worried climate scientists. It’s the classic good news/bad news scenario (or vice-versa, depending on your mood).

Proven and effective construction methods are not static, instead they're always improving. In Quebec, Canada, light wood frame and modular manufacturers are always pushing the limits of innovation. Their craft is now linked to building systems on a bold scale with offsite light wood frame construction.

There’s nothing green about your back-up generator. Manufacturing it released tons of CO2 into the atmosphere; so did shipping it from the factory to the dealership to your backyard. There it will sit, idle, waiting to be deployed only when the much cleaner—but underfunded—public infrastructure fails. At that point, it will fill the air with additional pollutants. There may be perfectly good reasons to buy an emergency generator but being green—that is, protecting the environment—isn’t one of them.

This August, as hundreds of wildfires darkened the sky above my home in Corte Madera, California, thousands of miles away in Florida, my family braced for wind and flooding as two hurricanes barreled towards the Gulf of Mexico. We all hunkered down, anxiously, as climate change-fueled disasters wreaked havoc. For weeks, the air quality in California was too hazardous for us to open our windows or go outside. In Pensacola, the Gulf storm surge was several feet deep around my family’s home and the powerful winds downed mature oak trees in their yard.

Since its installation in the late 1990s, a large clock in New York City’s Union Square has been counting up to 24 hours in each day with the number of hours, minutes, seconds, and milliseconds on display. However, the digital screen was recently repurposed as a Climate Clock and now projects the amount of time the world has left to take large-scale action on climate change- and the alarming truth, based on an IPCC Special Report on Global Warming counts down to only a little over seven years left until we reach the point of no return.

Curl la Tourelle Head Architecture received the green light to move forward with its latest “socially focused mixed-use scheme” that includes council homes, an adult education center, and affordable workspaces. Entitled Morland Gardens, the new project located in the London Borough of Brent, one of the district’s most deprived areas, is scheduled to start in the fall of 2020.

The Brundtland Report, 1987 - "Our Common Future" - introduced the notion that the sustainable use of natural resources must "meet the needs of the present generation without affecting the ability of future generations to meet theirs." Since then, the term sustainability has been popularized and, often, trivialized in our daily lives. In the construction industry, this is no different. As much as we know that to build, we need to destroy, how is it possible to mitigate the effects of construction during the useful life and demolition of buildings? A sustainable building, in its design, construction, and operation, must reduce or eliminate negative effects overall and may even generate net positive impacts on the climate and environment – preserving resources and improving the quality of life of the occupants simultaneously. To say that a building is sustainable is easy and even seductive. But what exactly makes sustainable construction?

Answering this question is not a simple exercise. That is why, in the last 30 years, several building sustainability certifications have been created. Through outsourced and impartial evaluations from different sources, they aim to verify the sustainable aspects of any construction. Each of them addresses particular building elements and is typically focused on certain regions of the world. While there are some certifications that verify whether the building meets certain efficiency criteria, others create different classifications, assigning a score based on these evaluations. Below, we list some of the primary sustainability certifications around the world – ranked alphabetically – and include their main architectural applications alongside a brief explanation:

Architects are mobilizing their efforts, to help schools around the world reconsider their design in order to guarantee sustainability, emotional wellness, and physical health. CetraRuddy, Cooper Robertson, and WXY are amongst those proposing an increase in outdoor programming and a rearrangement of classrooms, for post-pandemic school design.

The architectural scene has been witnessing lately a growing focus on indoor/outdoor functions. Discover 3 different interventions from 3 different practices, tackling one common issue, and focusing on outdoor space as a major programming element.

Architects and designers of the built environment are often conceptualized in popular culture as progressive change agents whose canvas of steel and glass brings light to the public realm. At least one global survey of the public’s trust in various professions places architects in a top-ranked cohort that includes medical professionals and first responders. But in the United States, the architecture profession is surprisingly older and much less progressive than one might imagine.

The Lisbon Architecture Triennale published on Vimeo the series of debates Talk, Talk, Talk held during its 5th edition, which was curated by Éric Lapierre. Divided into five major exhibitions, the Triennale addressed in one of them the issue of economy of means, discussed in the debates below.

I can’t stop thinking about refugia. In the years, months, and days before the COVID-19 pandemic, the term was confined to the literature and philosophy of climate crisis, referring to pockets of life that through geographic isolation or species resilience manage to hang on in spite of the environmental forces against them. Think of clusters of Pacific Northwest barnacles nestled high on coastal outcroppings to avoid falling prey to sea snails. Or old-growth forests insulated from rising temperatures in cool mountain valleys.

As self-quarantine set in earlier this spring, the word refugia, at least for me, expanded in definition from specific ecological condition to conceptual touchstone—a necessary leap to metaphor when faced with planetary crisis. The magnitude of this pandemic falls outside human comprehension, but for the luckiest of us, refuge is manageable: a place of relative safety, of sourdough starters and online Jazzercise classes.

Moving away from its early exclusive focus on natural disasters, resilient architecture and design tackles the much tougher challenge of helping ecosystems regenerate.

Thirty years ago, as a high school student at the Cranbrook boarding school in suburban Detroit, I wrote a research-based investigative report on the environmental crisis for the student newspaper. I had been encouraged to do so by a faculty adviser, David Watson, who lived a double life as a radical environmentalist writing under the pseudonym George Bradford for the anarchist tabloid Fifth Estate. His diatribe How Deep Is Deep Ecology? questioned a recurring bit of cant from the radical environmental movement: Leaders of groups like Earth First! frequently disparaged the value of human life in favor of protecting nature.
