How Breathable Should Facades Be? Exploring Permeability and Impermeability in Building Envelopes

The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.

While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.

The Greener Future of Automatic Door Systems: A Shift in Design and Performance

 | Sponsored Content

Throughout history, doors—and later automatic doors—have served a far greater purpose than merely marking an entrance or exit. They define thresholds, guide the flow of movement, and subtly shape the way people interact within a space. We can trace their evolution back to the 1st century, when Heron of Alexandria devised a steam-powered door—an early example of technology merging with architecture. Since then, contactless automatic door systems have incorporated technological advancements that enhance operation and redefine their role within buildings. Today, they are integrated across a range of building types and scales, acting as transitional elements that enhance comfort, energy efficiency, and the overall quality of indoor spaces.

Rethinking Sustainability Through Site-Specific Strategies

Subscriber Access | 

Sustainability in architecture is often framed as a universal challenge, leading to standardized solutions that prioritize efficiency over context. However, architecture is inherently tied to its environment — buildings interact with climate, topography, and cultural history in ways that demand specificity. Instead of relying on standardized sustainability checklists, how can architecture embrace site-specific solutions? This conversation is deeply connected to the concept of Genius Loci, or the spirit of a place, introduced by Christian Norberg-Schulz and embraced by architects advocating for designs that resonate with their surroundings. It suggests that architecture should not be imposed upon a site but rather emerge from it, informed by its materials, climate, and cultural significance. This philosophy challenges the widespread application of generic sustainable technologies, instead proposing that sustainability must be inherently tied to the location in which it operates.

Reconsidering Brutalist Renovations: A Transformation of the Boston City Hall for the Public

Boston City Hall, one of the most debated examples of Brutalist architecture in the United States, has significantly transformed since its conception. Designed by Kallmann, McKinnell, and Knowles and completed in 1968, the fortress-like concrete exterior and geometric austerity have long divided public opinion. Critics, including a former mayor, called for its demolition for decades arguing that its imposing design was inhospitable, inefficient, and most importantly, not beautiful. However, rather than tearing it down, Boston has chosen to renovate and revitalize the structure, demonstrating that contested Brutalist architectural styles can be adapted for a more sustainable future.
