Heat as a Design Partner: Trees, Soil, and Wind Corridors as Cooling Infrastructure

Jonathan Yeung — Fri, 12 Jun 2026 07:30:00 +0000

"By 2050, almost every child in the world — nearly 2.2 billion children — will be exposed to frequent heat waves." UNICEF's warning is often read as a public health forecast, but it is also a challenge to architecture and the way cities are built. As extreme heat intensifies across Asia, Europe, and beyond, thermal comfort should not be reduced to merely an indoor service delivered by machines. Air-conditioning has become a life-support system for many cities, especially in dense, humid, and rapidly urbanizing regions. Yet to rely on it as the default answer is to treat heat as something that can simply be moved elsewhere (and in the process generating extra heat) — expelled from interiors into streets, service alleys, energy grids, and the atmosphere. Its expansion increases energy demand, produces waste heat, and reinforces unequal access to comfort.

Dogtrot House: Vernacular Knowledge and Climate-Responsive Design

Olivia Poston — Wed, 13 May 2026 04:00:00 +0000

The dogtrot house emerged across the South of the United States during the late nineteenth century as a direct response to humid climates, material availability, and patterns of rural habitation. Found throughout the Appalachian Mountains, coastal Carolinas, and lowlands of Louisiana, the dogtrot house appeared in numerous regional variations, yet its fundamental spatial logic remained remarkably consistent. Two enclosed living masses are separated by an open central passage and unified beneath a continuous roof, creating a dwelling that is simultaneously economical and responsive to long, hot summers. Although architectural historians continue to debate the precise geographic origins of the dogtrot, the typology represents a broader vernacular intelligence that emerged through the convergence of environmental necessity, local construction practices, and rural living.

Tropical Modernism Beyond Aesthetics: The Politics of Shade and Air

Ananya Nayak — Mon, 04 May 2026 04:00:00 +0000

The image is familiar, a façade layered with brise-soleil, light softened into a patterned shadow, interiors kept cool without machines. It appears as intelligence made visible, architecture that understands the sun. This image is rarely examined closely. The same devices that temper heat also organize access, distribute comfort, and depend on particular forms of labor. What looks like a climatic response is also a decision about who gets relief from heat, and how. Tropical modernism, often reduced to a visual language of shade and porosity, emerges instead as a set of situated practices where climate, labor, and power are negotiated differently across contexts.

Designing with Air: Rethinking Architecture Beyond the Wall

Diogo Borges Ferreira — Sat, 02 May 2026 07:30:00 +0000

Architecture is traditionally chronicled through the persistence of the solid. We define the discipline by the weight of the lintel, the mass of the pier, and the resistance of the wall. Even when lightness is invoked, it is usually understood as a subtractive act, the thinning of a section or the precarious reduction of a load. Yet there is a parallel history, less visible and harder to isolate, in which the primary material of construction is not what occupies space, but what moves through it.

The Courtyard as Architecture’s Lightest Cooling System

Ananya Nayak — Mon, 27 Apr 2026 07:30:00 +0000

The courtyard is often remembered as a figure from the past, an inward-looking space of nostalgia, culture, and domestic ritual. But this framing misses its primary role. Before it was symbolic, the courtyard was operational. It organized air, moderated light, and absorbed heat. It did not decorate architecture; it made it habitable. In contemporary housing, these functions are normally delegated to mechanical systems, applied after form is fixed. In courtyard houses, they are resolved spatially, before a wall is even built.

Podium–Tower Urbanism in Southeast Asia: Density, Management, and the Disappearing Street

Jonathan Yeung — Thu, 23 Apr 2026 04:00:00 +0000

If elevated networks reveal a city that increasingly walks above the street, the podium–tower is the typology that often makes that condition feel inevitable. Across Southeast Asia, podium–tower projects have become one of the dominant languages of metropolitan growth: a system that concentrates housing, jobs, retail, and transit connections into highly legible and managed parcels. From an urban planning perspective, the model can be remarkably effective—absorbing congestion, formalizing circulation, and delivering density quickly. Yet as it spreads, the typology also raises a quieter question: what does it optimize for, and what does it erode—especially at the level of the street, where urban life is meant to be negotiated rather than curated?

Jaali, Mashrabiya, Cobogó: The Lightest Skins in Architecture

Ananya Nayak — Mon, 20 Apr 2026 07:30:00 +0000

A perforated screen is often treated as an afterthought, something applied to soften light, to decorate a façade, or to add texture where a wall might otherwise feel flat. It is photographed as a surface, drawn as a pattern, and discussed as a craft. But in many buildings across the Indian subcontinent and the Islamic world, the screen was never an addition. It was the wall itself. Remove it, and the building does not simply change in appearance; it loses its ability to regulate heat, move air, and mediate between inside and outside.

Designed Comfort, Purchased Comfort: Passive Design and Air Conditioning in Hong Kong

Jonathan Yeung — Thu, 02 Apr 2026 07:30:00 +0000

Establishing thermal comfort once demanded a far more deliberate and calibrated architectural intelligence—an interplay of orientation, massing, material behavior, ventilation potential, shading, and the ways daylight and surfaces absorb and release heat. This was not simply a matter of taste, but of necessity. When many of Hong Kong's post-war modernist buildings were constructed in the late 1960s and 1970s, forming a substantial portion of the city's public housing and broader residential stock, air-conditioning was not yet a ubiquitous, default service. Cooling, where present at all, was limited and unevenly distributed; comfort had to be negotiated through passive means, through section, façade depth, operable openings, and climatic detailing. It was only later, particularly through the 1970s and 1980s, as air-conditioning became increasingly standardized across the region, that mechanical cooling began to displace this earlier matrix of architectural decision-making.

Thermal Memory: How Climate Shapes Architectural Heritage

Ananya Nayak — Fri, 27 Feb 2026 05:00:00 +0000

On a hot afternoon in May, when the air over western India turns metallic with heat, no one remembers façade composition. They remember where the shade falls. They remember which corridor breathed. They remember the house that was cooler than the street. What stays in memory is comfort beyond the form. Repeated thermal preference stabilizes into spatial configuration, and over time, those configurations become building types.

COP30 Outcomes for the Built Environment: From Sustainable Cooling to Climate Adaptation Commitments

Antonia Piñeiro — Tue, 25 Nov 2025 05:30:00 +0000

On November 21, 2025, the closing day of the 30th edition of the Conference of the Parties (COP) took place, the yearly gathering of United Nations member states to negotiate international climate agreements and assess global progress toward emissions reduction. This year, the event was held in Belém, Brazil, a port city of fewer than 1.5 million people, widely known as a gateway to Brazil's lower Amazon region. First convened in 1992, UN Climate Change Conferences (or COPs) are an international multilateral decision-making forum on climate change involving 198 "Parties" (197 countries, nearly all of them, depending on definitions of country, and the European Union). Their purpose is to assess global efforts toward the central Paris Agreement aim of limiting global warming to as close as possible to 1.5 °C above pre-industrial levels. The event brings together leaders and negotiators from member states, business figures, young people, climate scientists, Indigenous Peoples, and civil society around issues considered essential to that climate goal. This year, COP30 was marked by strong criticism of its ties to the fossil fuel industry, descriptions of agreements as fragile and insubstantial, and the struggle to move climate finance "from pledge to lifeline."

Hong Kong's Queensway Reimagined: Sara Klomps on the Genesis and Ambition of The Henderson by Zaha Hadid Architects

Jonathan Yeung — Mon, 07 Jul 2025 04:00:00 +0000

Architectural landmarks often cluster together. In Tokyo, the iconic Omotesando is a well-known stretch where global "starchitects" built flagship luxury retail spaces in the 2000s. Hong Kong has a lesser-known but equally powerful architectural agglomeration along Queensway—though historically more corporate and less publicly engaging. Beginning in the 1980s, this corridor became home to a series of landmark buildings by some of the world's most prominent architects: Norman Foster's HSBC Headquarters, I.M. Pei's Bank of China Tower, Paul Rudolph's Lippo Centre, and the nearby Murray Building by Ron Phillips—now revitalized as a hotel by Foster + Partners. The area is further enriched later on by Heatherwick Studio's renovation of Pacific Place and Tod Williams Billie Tsien Architects' Asia Society Hong Kong Center.

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

Maria-Cristina Florian — Wed, 28 May 2025 04:00:00 +0000

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.

Designing for Temperature Gradients: 6 Central American Projects that Use Transitional Spaces to Mitigate Heat

Moises Carrasco — Sat, 17 May 2025 07:30:00 +0000

Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.

Bahrain’s 2025 Venice Biennale Pavilion Addresses the Global Issue of Extreme Heat

Reyyan Dogan — Mon, 05 May 2025 06:30:00 +0000

The Kingdom of Bahrain's national pavilion at the 19th International Architecture Exhibition of La Biennale di Venezia was awarded this year's Golden Lion for Best National Participation. Titled Heatwave, the exhibition was curated by architect Andrea Faraguna and located in the historic Artiglierie of the Arsenale. Through a site-specific installation, Heatwave reimagines the design of public space by exploring passive cooling strategies rooted in Bahrain's climatic realities and cultural context. The project's aim, to offer a speculative yet grounded architectural response to the environmental urgency shaping urban life today, was recognized by the Biennale's international jury, which praised its "viable proposals for extreme heat conditions."

Rethinking Sustainability Through Site-Specific Strategies

Diogo Borges Ferreira — Thu, 13 Mar 2025 07:30:00 +0000

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.

Revisiting Skyscraper Design: The Benefits of Responsive Facades and Passive Designs

Jonathan Yeung — Mon, 28 Oct 2024 04:00:00 +0000

Our contemporary society has been witnessing a surge in skyscraper construction in urban centers worldwide for various reasons—including engineering advancements, increased urban density, space constraints, and, arguably, a competitive drive for building the tallest structures. The allure of all-glass facades and the pursuit of curtain walls with larger panes of continuous glass have often come at the cost of functionality.
