"Let us take a hard look at the facts." With this direct and hardly reassuring sentence, the director of the Office of Civil and Defense Mobilization opened The Family Fallout Shelter, a 32-page manual published by the U.S. government in 1959 amid Cold War tensions. The document taught families how to build shelters capable of protecting them from radioactive fallout after a possible nuclear attack and, through technical drawings and sketches, outlined solutions using concrete blocks, walls filled with earth or sand, underground structures, and ventilation systems. It was a survival manual that, in many ways, also functioned as a construction manual.
Against a backdrop of climate change, inflation, and armed conflict, the global energy system is undergoing change and facing scrutiny. As stated by the United Nations, buildings must be heated, lit, and electrified through clean, accessible, affordable, sustainable, and reliable power sources. Architecture and urban planning can contribute both to expanding energy access and to exploring different forms of storage. The Toronto-based startup Civic Grid designs and builds energy storage systems with the aim of changing the relationship communities have with the electrical power behind everyday life. Their first architectural battery was designed as public architecture by architects Jack Self and Josh Harskamp with industrial designer Max Fine. The prototype is the evolution of a deployable energy system developed with Lisbon Civil Defence for the Lisbon Architecture Triennale 2025, still in operation, and is paired with a scale model.
"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.
Heat, however, does not stop at the human body. It reorganizes the wider urban ecosystem: trees struggle with compacted soil and radiant paving; birds and insects lose habitat when planting is reduced to decorative greenery; aquatic systems warm, microbial life shifts, and materials absorb and release heat long after the sun has set. Heat is not simply a climatic problem to be escaped indoors. It is an urban actor that reshapes public space, labor, mobility, planting, material choices, and the fragile relationships between human and nonhuman life.
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.
Did air conditioning negatively affect architectural space, particularly in Hong Kong and the nearby region? The more precise claim is that widespread reliance on AC has profoundly rearranged the incentive structure of building design.
Beyond being a source of life, the power of the sun in architecture has long been tied to humanity's need to harness and control it as a vital resource. Since ancient times, solar energy has been used to measure time, support planting and harvesting, and provide protection from heat and cold. Today, solar radiation plays a significant role in global energy consumption. Architectural solutions based on materials, technologies, and environmental analysis are developed with an understanding of solar energy's capacity to transform the interior environment of buildings. But how can buildings be transformed into sources of clean energy?
For centuries, large-scale infrastructure operated in the background. Ports, power plants, and energy facilities were positioned at the edges of cities, designed primarily for efficiency, and rarely considered part of civic life. Their function was indispensable, yet their architectural presence remained secondary. These structures supported urban growth and global exchange while maintaining a spatial distance from everyday urban experience.
Today, this condition is gradually shifting. As global trade intensifies and energy systems expand in complexity, the buildings that coordinate and house these networks are becoming more visible within the urban landscape. Rather than remaining neutral containers for technical operations, they begin to assert spatial identity. Infrastructure is no longer only operational; it is increasingly institutional, symbolic, and urban. The architecture that supports these systems now participates in how cities project themselves.

We are excited to invite submissions for DARK MATTER: Revisiting the Architecture of Coal in Post-War Europe, an in-person conference hosted by the ACME (Architecture of Coal in Modern Europe) project (ERC Advanced Grant, 2024–2030), taking place at the Irish Architectural Archive, Dublin on 5+6 November 2026.
January 26 marks the International Day for Clean Energy, an initiative aimed at raising awareness and mobilizing action for an inclusive transition from fossil fuels, such as coal, oil, and natural gas, to power generation systems with lower greenhouse gas emissions and fewer pollutants. The term "clean" signals a fundamental shift away from extractive, finite, and exhaustible energy sources toward systems based on renewable resources or on capturing energy embedded in natural processes. In a world grappling with climate change, clean energy plays an important role in reducing emissions and expanding access to reliable power. However, being labeled "clean" does not exempt these systems from the impacts associated with their production, deployment, and commercialization. In this context, architectural knowledge related to space, materiality, and habitation becomes relevant for supporting a transition toward energy systems that are sustainable over time. As stated by the United Nations, the science is clear: to limit climate change, reliance on fossil fuels must end, and buildings must be heated, lit, and electrified through clean, accessible, affordable, sustainable, and reliable power sources.
The project brings together architects, artists, researchers, scientists, and social workers, the project explores how embodied, material, and technological practices can help us rethink our relationship with the planet’s energy infrastructures.
Thirty trillion tons. This is the estimated mass of all human-made matter on Earth, and the starting point for the 7th edition of the Lisbon Architecture Triennale. Curated by Ann-Sofi Rönnskog and John Palmesino, founders of Territorial Agency, the event asks a deceptively simple question: How heavy is a city? To answer it requires more than data. It demands a shift in perception: from the scale of the city to the planetary technosphere.
The technosphere, a term borrowed from Earth sciences, defines the vast system of infrastructures, technologies, and materials that sustain human life while reshaping the planet. Cities, in this view, are not only territories but dense nodes within this planetary metabolism. From October to December 2025, Lisbon becomes a lens to examine that magnitude, hosting three main exhibitions (Fluxes, Spectres, Lighter), a book of essays, a talks program, and more than twenty independent projects across the city.
The Deutsches Architekturmuseum (DAM) in Frankfurt has launched its new exhibitionArchitecture and Energy: Building in the Age of Climate Change on June 14, which will be open to visitors until October 5, 2025. Developed in collaboration with engineer and sustainability advocate Werner Sobek, the exhibition explores the intersections of architecture, energy, and climate, focusing on the environmental impact of the built environment and the role of architecture in mitigating climate change. By framing architecture as both a challenge and an opportunity in the context of the climate crisis, the exhibition seeks to contribute to a broader shift in thinking, one that positions design as a vital component of a sustainable future.
