Casa Sofia | © Fernando Guerra / FG+SG Located in the historic heart of Lagos, Portugal, Casa Sofia by Mário Martins Atelier is a thoughtful exercise in urban integration and contemporary reinterpretation. Occupying a site once held by a modest two-story house, the project is situated on the corner of a block facing the Church of St Sebastião. With its commanding presence, this national monument set a formidable challenge for the architects: introducing a new residence that respects the weight of history while offering a clear, contemporary expression. Casa Sofia Technical Information Architects1-4: Mário Martins Atelier Location: Lagos, Portugal Project Completion Years: 2023 Photographs: © Fernando Guerra / FG+SG It is therefore important to design a building to fit into and complete the block. A house that is quiet and solid, with rhythmic metrics, whose new design brings an identity, with the weight and scent of the times, to a city that has existed for many centuries. – Mário Martins Atelier Casa Sofia Photographs © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG Spatial Organization and Circulation The design’s ambition is anchored in reconciling modern residential needs with the dense urban fabric that defines the walled city. Rather than imposing a bold or disruptive form, the project embraces the existing rhythms and textures of the surrounding architecture. The result is a building that both defers to and elevates the neighborhood’s character. Its restrained profile and carefully modulated facade echo the massing and articulation of the original house while introducing an identity that is clearly of its time. At the core of Casa Sofia’s spatial organization is a deliberate hierarchy of spaces that transitions seamlessly between public, semi-public, and private domains. Entry from the street occurs through a modest set of steps leading to an exterior atrium. This threshold mediates the relationship between the public realm and the interior, grounding the house in its urban context. Once inside, an open hall reveals the vertical flow of the building, dominated by a staircase that appears to float, linking the house’s various levels while maintaining visual continuity throughout. The ground floor houses three bedrooms, each with an ensuite bathroom, radiating from the central hall. This level also contains a small basement for technical support, reinforcing the discreet layering of functional and domestic spaces. Midway up the staircase, the house opens onto a garage, a laundry room, and an intimate courtyard. These areas, essential for daily life, are seamlessly integrated into the overall composition, contributing to a spatial richness that is both pragmatic and sensorial. On the first floor, an open-plan arrangement accommodates the main living spaces. Around a central void, the living and dining areas, kitchen, and master suite are arranged to encourage visual interplay and shared light. This configuration enhances the spatial porosity, ensuring that despite the density of the historic center, the house retains a sense of openness and fluidity. Above, a recessed roof level recedes from the street, culminating in a panoramic terrace with a swimming pool. Here, the building dissolves into the sky, offering expansive views and light-filled leisure spaces that contrast with the more enclosed lower floors. Materiality and Craftsmanship Materiality plays a decisive role in mediating the building’s relationship with its context. White-painted plaster, a familiar element in the region, is punctuated by deep limestone moldings. These details create a play of light and shadow that emphasizes the facade’s verticality and rhythm. The generous thickness of the walls, carried over from the site’s earlier construction, lends a sense of solidity and permanence to the house, recalling the tactile traditions of the Algarve’s architecture. The interior and exterior detailing is characterized by an economy of means, where each material is selected for its ability to reinforce the house’s quiet presence. Local materials and craftsmanship ground the project in its immediate context while responding to environmental imperatives. High thermal comfort is achieved through careful orientation and passive design strategies, complemented by the integration of solar control and water conservation measures. These considerations underscore the project’s commitment to sustainability without resorting to superficial gestures. Broader Urban and Cultural Implications Beyond its immediate function as a family home, Casa Sofia engages in a broader dialogue with its urban and cultural surroundings. The project exemplifies a measured response to the question of how to build within a historical setting without resorting to nostalgia or pastiche. It demonstrates that contemporary architecture can find resonance within heritage contexts by prioritizing the values of continuity, scale, and material authenticity. In its measured dialogue with the Church of St Sebastião and the centuries-old urban landscape of Lagos, Casa Sofia illustrates the potential for architecture to enrich the experience of place through quiet, rigorous interventions. It is a project that reaffirms architecture’s capacity to negotiate between past and present, crafting spaces that are at once deeply contextual and unambiguously of their moment.

June 13, 20256 min readAir-Conditioning Can Surprisingly Help the Power Grid during Extreme HeatSwitching on air-conditioning during extreme heat doesn’t have to make us feel guilty—it can actually boost power grid reliability and help bring more renewable energy onlineBy Johanna Mathieu & The Conversation US Imagedepotpro/Getty ImagesThe following essay is reprinted with permission from The Conversation, an online publication covering the latest research.As summer arrives, people are turning on air conditioners in most of the U.S. But if you’re like me, you always feel a little guilty about that. Past generations managed without air conditioning – do I really need it? And how bad is it to use all this electricity for cooling in a warming world?If I leave my air conditioner off, I get too hot. But if everyone turns on their air conditioner at the same time, electricity demand spikes, which can force power grid operators to activate some of the most expensive, and dirtiest, power plants. Sometimes those spikes can ask too much of the grid and lead to brownouts or blackouts.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Research I recently published with a team of scholars makes me feel a little better, though. We have found that it is possible to coordinate the operation of large numbers of home air-conditioning units, balancing supply and demand on the power grid – and without making people endure high temperatures inside their homes.Studies along these lines, using remote control of air conditioners to support the grid, have for many years explored theoretical possibilities like this. However, few approaches have been demonstrated in practice and never for such a high-value application and at this scale. The system we developed not only demonstrated the ability to balance the grid on timescales of seconds, but also proved it was possible to do so without affecting residents’ comfort.The benefits include increasing the reliability of the power grid, which makes it easier for the grid to accept more renewable energy. Our goal is to turn air conditioners from a challenge for the power grid into an asset, supporting a shift away from fossil fuels toward cleaner energy.Adjustable equipmentMy research focuses on batteries, solar panels and electric equipment – such as electric vehicles, water heaters, air conditioners and heat pumps – that can adjust itself to consume different amounts of energy at different times.Originally, the U.S. electric grid was built to transport electricity from large power plants to customers’ homes and businesses. And originally, power plants were large, centralized operations that burned coal or natural gas, or harvested energy from nuclear reactions. These plants were typically always available and could adjust how much power they generated in response to customer demand, so the grid would be balanced between power coming in from producers and being used by consumers.But the grid has changed. There are more renewable energy sources, from which power isn’t always available – like solar panels at night or wind turbines on calm days. And there are the devices and equipment I study. These newer options, called “distributed energy resources,” generate or store energy near where consumers need it – or adjust how much energy they’re using in real time.One aspect of the grid hasn’t changed, though: There’s not much storage built into the system. So every time you turn on a light, for a moment there’s not enough electricity to supply everything that wants it right then: The grid needs a power producer to generate a little more power. And when you turn off a light, there’s a little too much: A power producer needs to ramp down.The way power plants know what real-time power adjustments are needed is by closely monitoring the grid frequency. The goal is to provide electricity at a constant frequency – 60 hertz – at all times. If more power is needed than is being produced, the frequency drops and a power plant boosts output. If there’s too much power being produced, the frequency rises and a power plant slows production a little. These actions, a process called “frequency regulation,” happen in a matter of seconds to keep the grid balanced.This output flexibility, primarily from power plants, is key to keeping the lights on for everyone.Finding new optionsI’m interested in how distributed energy resources can improve flexibility in the grid. They can release more energy, or consume less, to respond to the changing supply or demand, and help balance the grid, ensuring the frequency remains near 60 hertz.Some people fear that doing so might be invasive, giving someone outside your home the ability to control your battery or air conditioner. Therefore, we wanted to see if we could help balance the grid with frequency regulation using home air-conditioning units rather than power plants – without affecting how residents use their appliances or how comfortable they are in their homes.From 2019 to 2023, my group at the University of Michigan tried this approach, in collaboration with researchers at Pecan Street Inc., Los Alamos National Laboratory and the University of California, Berkeley, with funding from the U.S. Department of Energy Advanced Research Projects Agency-Energy.We recruited 100 homeowners in Austin, Texas, to do a real-world test of our system. All the homes had whole-house forced-air cooling systems, which we connected to custom control boards and sensors the owners allowed us to install in their homes. This equipment let us send instructions to the air-conditioning units based on the frequency of the grid.Before I explain how the system worked, I first need to explain how thermostats work. When people set thermostats, they pick a temperature, and the thermostat switches the air-conditioning compressor on and off to maintain the air temperature within a small range around that set point. If the temperature is set at 68 degrees, the thermostat turns the AC on when the temperature is, say, 70, and turns it off when it’s cooled down to, say, 66.Every few seconds, our system slightly changed the timing of air-conditioning compressor switching for some of the 100 air conditioners, causing the units’ aggregate power consumption to change. In this way, our small group of home air conditioners reacted to grid changes the way a power plant would – using more or less energy to balance the grid and keep the frequency near 60 hertz.Moreover, our system was designed to keep home temperatures within the same small temperature range around the set point.Testing the approachWe ran our system in four tests, each lasting one hour. We found two encouraging results.First, the air conditioners were able to provide frequency regulation at least as accurately as a traditional power plant. Therefore, we showed that air conditioners could play a significant role in increasing grid flexibility. But perhaps more importantly – at least in terms of encouraging people to participate in these types of systems – we found that we were able to do so without affecting people’s comfort in their homes.We found that home temperatures did not deviate more than 1.6 Fahrenheit from their set point. Homeowners were allowed to override the controls if they got uncomfortable, but most didn’t. For most tests, we received zero override requests. In the worst case, we received override requests from two of the 100 homes in our test.In practice, this sort of technology could be added to commercially available internet-connected thermostats. In exchange for credits on their energy bills, users could choose to join a service run by the thermostat company, their utility provider or some other third party.Then people could turn on the air conditioning in the summer heat without that pang of guilt, knowing they were helping to make the grid more reliable and more capable of accommodating renewable energy sources – without sacrificing their own comfort in the process.This article was originally published on The Conversation.

The government has axed a scheme for upgrading energy efficiency in public sector buildings. The Public Sector Decarbonisation Scheme (PSDS) delivered more than £2.5bn in its first three phases for measures such as heat pumps, solar panels, insulation and double glazing, with further funding of nearly £1bn recently announced. But the Department for Energy Security and Net Zero (DESNZ) has told Building Design that the scheme has been dropped after the spending review, leaving uncertainty about how upgrades will be funded when the current phase expires in 2028. Source: UK Government/FlickrEd Miliband’s Department for Energy Security and Net Zero is responsible for the scheme The department said it would set out plans for the period after 2028 in due course. In a post on LinkedIn, Dave Welkin, director of sustainability at Gleeds, said he had waited for the release of the spending review with a “sense of trepidation” and was unable to find mention of public sector decarbonisation when Treasury documents were released. “I hoped because it was already committed in the Budget that its omission wasn’t ominous,” he wrote. Yesterday, he was told by Salix Finance, the non-departmental public body that delivers funding for the scheme, that it was no longer being funded. It comes after the withdrawal of funding for the Low Carbon Skills Fund (LCSF) in May. According to the government’s website, PSDS and LCSF were intended to support the reduction of emissions from public sector buildings by 75% by 2037, compared to a 2017 baseline. “Neither LCSF or PSDS were perfect by any means, but they did provide a vital source of funding for local authorities, hospitals, schools and many other public sector organisations to save energy, carbon and money,” Welkin said. “PSDS has helped replace failed heating systems in schools, keeping students warm. It’s replaced roofs on hospitals, helping patients recover from illness. It’s replaced windows in our prisons, improving security and stopping drugs getting behind bars.” However, responding to Welkin’s post, Steve Connolly, chief executive at Arriba Technologies, a low carbon heating and cooling firm, said that the scheme was being “mismanaged” with a small number of professional services firms “scooping up disproportionately large grants for their clients”. The fourth phase of the scheme was confirmed last September, with allocations confirmed only last month. This latest phase, which covers the financial years between 2025/26 and 2027/28, saw the distribution of £940m across the country. A DESNZ spokesperson said: “Our settlement is about investing in Britain’s renewal to create energy security, sprint to clean power by 2030, encourage investment, create jobs and bring down bills for good. “We will deliver £1bn in current allocations of the Public Sector Decarbonisation Scheme until 2028 and, through Great British Energy, have invested in new rooftop solar power and renewable schemes to lower energy bills for schools and hospitals across the UK. “We want to build on this progress by incentivising the public sector to decarbonise, so they can reap the benefits in lower bills and emissions, sharing best practice across government and exploring the use of repayable finance, where appropriate.” A government assessment of phase 3a and 3b projects identified a number of issues with the scheme, including delays and cost inflation, with more than a tenth being abandoned subsequent to grants being offered. Stakeholders interviewed for the report also identified “difficulties in obtaining skilled contractors and equipment”, especially air source heat pumps. The first come first served approach to awarding funding was also said to be “encouraging applicants to opt for more straightforward projects” and “potentially undermining the achievement of PSDS objective by restricting the opportunity for larger [and] more complex measures which may have delivered greater carbon reduction benefits”. But the consensus among stakeholders and industry representatives interviewed for the report was that the scheme was “currently key to sustaining the existing UK heat pump market” and that it was “seen as vital in enabling many public sector organisations to invest in heat decarbonisation”.

News Climate This paint ‘sweats’ to keep your house cool A new cement-based paint cools buildings by combining sunlight reflection and water evaporation A new cooling paint reflects sunlight and mimics sweat to reduce air-conditioning use. Marie LaFauci/Getty Images By Larissa G. Capella June 13, 2025 at 11:00 am A cool house without air conditioning may soon be possible. Scientists in Singapore have developed a new type of paint that reflects sunlight and cools surfaces by slowly evaporating water. Unlike other commercially available cooling paints, which are designed to repel water to protect the underlying material, the new one even works in hot, humid places, offering a low-energy way to stay cool, researchers report June 5 in Science. “The key is passive cooling,” which requires no energy input, says material scientist Li Hong In other words, it works without using electricity or mechanical systems. Right now, radiative cooling is the most common type of passive cooling used in materials, including certain paints. It works by reflecting sunlight and radiating heat from a surface such as walls or roofs, into the sky. But in humid places like Singapore, water vapor in the air traps heat near the surface, which prevents it from escaping into the atmosphere and keeps the surfaces warm. In response, Hong and two other material scientists from Nanyang Technological University developed a cement-based paint that combines three cooling strategies: radiative cooling, evaporative cooling, which our skin uses, and solar reflection. In the study, the scientists painted three small houses: one with regular white paint, one with commercial cooling paint that uses only radiative cooling and one with their new formula. After two years of sun and rain in Singapore, the first two paints had turned yellow. But “our paint was still white,” says coauthor Jipeng Fei. Unlike other colors, white helps materials maintain their high reflectivity and cooling performance. Sign up for our newsletter We summarize the week's scientific breakthroughs every Thursday.

In a nutshell: As nations set ever more ambitious targets for renewable energy and electrification, the humble high-voltage cable has emerged as a linchpin – and a potential chokepoint – in the race to decarbonize the global economy. A Bloomberg interview with Claes Westerlind, CEO of NKT, a leading cable manufacturer based in Denmark, explains why. A global surge in demand for high-voltage electricity cables is threatening to stall the clean energy revolution, as the world's ability to build new wind farms, solar plants, and cross-border power links increasingly hinges on a supply chain bottleneck few outside the industry have considered. At the center of this challenge is the complex, capital-intensive process of manufacturing the giant cables that transport electricity across hundreds of miles, both over land and under the sea. Despite soaring demand, cable manufacturers remain cautious about expanding capacity, raising questions about whether the pace of electrification can keep up with climate ambitions, geopolitical tensions, and the practical realities of industrial investment. High-voltage cables are the arteries of modern power grids, carrying electrons from remote wind farms or hydroelectric dams to the cities and industries that need them. Unlike the thin wires that run through a home's walls, these cables are engineering marvels – sometimes as thick as a person's torso, armored to withstand the crushing pressure of the ocean floor, and designed to last for decades under extreme electrical and environmental stress. "If you look at the very high voltage direct current cable, able to carry roughly two gigawatts through two pairs of cables – that means that the equivalent of one nuclear power reactor is flowing through one cable," Westerlind told Bloomberg. The process of making these cables is as specialized as it is demanding. At the core is a conductor, typically made of copper or aluminum, twisted together like a rope for flexibility and strength. Around this, manufacturers apply multiple layers of insulation in towering vertical factories to ensure the cable remains perfectly round and can safely contain the immense voltages involved. Any impurity in the insulation, even something as small as an eyelash, can cause catastrophic failure, potentially knocking out power to entire cities. // Related Stories As the world rushes to harness new sources of renewable energy, the demand for high-voltage direct current (HVDC) cables has skyrocketed. HVDC technology, initially pioneered by NKT in the 1950s, has become the backbone of long-distance power transmission, particularly for offshore wind farms and intercontinental links. In recent years, approximately 80 to 90 percent of new large-scale cable projects have utilized HVDC, reflecting its efficiency in transmitting electricity over vast distances with minimal losses. But this surge in demand has led to a critical bottleneck. Factories that produce these cables are booked out for years, Westerlind reports, and every project requires custom engineering to match the power needs, geography, and environmental conditions of its route. According to the International Energy Agency, meeting global clean energy goals will require building the equivalent of 80 million kilometers (around 49.7 million miles) of new grid infrastructure by 2040 – essentially doubling what has been constructed over the past century, but in just 15 years. Despite the clear need, cable makers have been slow to add capacity due to reasons that are as much economic and political as technical. Building a new cable factory can cost upwards of a billion euros, and manufacturers are wary of making such investments without long-term commitments from utilities or governments. "For a company like us to do investments in the realm of €1 or 2 billion, it's a massive commitment... but it's also a massive amount of demand that is needed for this investment to actually make financial sense over the next not five years, not 10 years, but over the next 20 to 30 years," Westerlind said. The industry still bears scars from a decade ago, when anticipated demand failed to materialize and expensive new facilities sat underused. Some governments and transmission system operators are trying to break the logjam by making "anticipatory investments" – committing to buy cable capacity even before specific projects are finalized. This approach, backed by regulators, gives manufacturers the confidence to expand, but it remains the exception rather than the rule. Meanwhile, the industry's structure itself creates barriers to rapid expansion, according to Westerlind. The expertise, technology, and infrastructure required to make high-voltage cables are concentrated in a handful of companies, creating what analysts describe as a "deep moat" that is difficult for new entrants to cross. Geopolitical tensions add another layer of complexity. China has built more HVDC lines than any other country, although Western manufacturers, such as NKT, maintain a technical edge in the most advanced cable systems. Still, there is growing concern in Europe and the US about becoming dependent on foreign suppliers for such critical infrastructure, especially in light of recent global conflicts and trade disputes. "Strategic autonomy is very important when it comes to the core parts and the fundamental parts of your society, where the grid backbone is one," Westerlind noted. The stakes are high. Without a rapid and coordinated push to expand cable manufacturing, the world's clean energy transition could be slowed not by a lack of wind or sun but by a shortage of the cables needed to connect them to the grid. As Westerlind put it, "We all know it has to be done... These are large investments. They are very expensive investments. So also the governments have to have a part in enabling these anticipatory investments, and making it possible for the TSOs to actually carry forward with them."

Casa Morena | © Fernando Guerra / FG+SG In the coastal enclave of Lagos, Portugal, Mário Martins Atelier has crafted Casa Morena. This residence quietly asserts itself as an ode to the dialogue between architecture and its natural setting. Completed in 2024, this project demonstrates a considered response to its environment, where the interplay of light, material, and landscape defines a sense of place rather than architectural imposition. Casa Morena Technical Information Architects1-5: Mário Martins Atelier Location: Lagos, Portugal Project Years: 2024 Photographs: © Fernando Guerra / FG+SG A simple house, one that wishes to be discreet and to be influenced by its location, to become a house that is pleasant with thoughtful landscaping. – Mário Martins Atelier Casa Morena Photographs © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG © Fernando Guerra / FG+SG A Contextual Response to Landscape and Light The design of Casa Morena finds its genesis in the site itself, a pine-scented plot overlooking the expanse of a bay. The pine trees, longstanding witnesses to the landscape’s evolution, provide the project’s visual anchor and spatial logic. In a move that both respects and celebrates these natural elements, Mário Martins Atelier structured the house’s reticulated plan to echo the presence of the trees, creating a composition that unfolds as a series of volumes harmonizing with the vertical rhythm of the trunks. The solid base of the house, built from locally sourced schist, emerges directly from the terrain. These robust walls establish a tactile continuity with the ground, their rough textures anchoring the architecture within the landscape. In contrast, the upper volumes of the house adopt a distinctly lighter expression: horizontal planes rendered in white plaster, their smooth surfaces catching and refracting the region’s luminous sun. This duality, earthbound solidity, and aerial lightness establish an architectural narrative rooted in the elemental. Casa Morena Experiential Flow Casa Morena’s spatial arrangement articulates a clear hierarchy of public and private domains. On the ground floor, the house embraces openness and transparency. An expansive entrance hall blurs the threshold inside and out, guiding inhabitants and visitors into a luminous social heart. The lounge, kitchen, and office flow seamlessly into the garden, unified by a continuous glazed façade that invites the outside in. This deliberate porosity extends to a covered terrace, an intermediary space that dissolves the boundary between shelter and exposure. The terrace, framed by the garden’s green canopy and the swimming pool’s long line, becomes a place of repose and contemplation. The pool itself demarcates the transition from a cultivated garden to the looser, more rugged landscape beyond, its linear form echoing the horizon’s expanse. Ascending to the upper floor, the architectural language shifts towards intimacy. The bedrooms, each with direct access to terraces and patios, create secluded zones that still maintain a fluid relationship with the outdoors. A discreet rooftop terrace, accessible from these private quarters, offers a hidden sanctuary where the interplay of views and light remains uninterrupted. Material Tectonics and Environmental Strategy Casa Morena’s material palette is rooted in regional specificity and tactile sensibility. Schist, extracted from the site, is not merely a structural element but a narrative thread linking the building to its geological past. Its earthy warmth and rugged surface provide a counterpoint to the luminous white of the upper volumes, an articulation of contrast that enlivens the building’s silhouette. White, the chromatic signature of the Algarve region, is employed with restraint and nuance. Its reflective qualities intensify the play of shadow and light, a dynamic that shifts with the passing of the day. In this interplay, architecture becomes an instrument for registering the ephemeral, and the environment itself becomes a participant in the spatial drama. Environmental stewardship is also woven into the project’s DNA. Discreetly integrated systems on the roof harness solar energy and manage water resources, extending the house’s commitment to a sustainable coexistence with its setting.
