Solar air heating is among the most cost-effective applications of solar thermal energy. These systems are used for space heating and preheating fresh air for ventilation, typically using glazed or unglazed perforated solar collectors. The collectors draw in outside air, heat it using solar energy, and then distribute it through ductwork to meet building heating and fresh air needs. In 2024, Canada led again the world for the at least seventh year in a row in solar air heating adoption. The four key suppliers – Trigo Energies, Conserval Engineering, Matrix Energy, and Aéronergie – reported a combined 26,203 m2 (282,046 ft2) of collector area sold last year. Several of these providers are optimistic about the growing demand. These findings come from the newly released Canadian Solar Thermal Market Survey 2024, commissioned by Natural Resources Canada. Canada is the global leader in solar air heating. The market is driven by a strong network of experienced system suppliers, optimized technologies, and a few small favorable funding programs – especially in the province of Quebec. Architects and developers are increasingly turning to these cost-effective, façade-integrated systems as a practical solution for reducing onsite natural gas consumption. Despite its cold climate, Canada benefits from strong solar potential with solar irradiance in many areas rivaling or even exceeding that of parts of Europe. This makes solar air heating not only viable, but especially valuable in buildings with high fresh air requirements including schools, hospitals, and offices. The projects highlighted in this article showcase the versatility and relevance of solar air heating across a range of building types, from new constructions to retrofits. Figure 1: Preheating air for industrial buildings: 2,750 m2 (29,600 ft2) of Calento SL solar air collectors cover all south-west and south-east facing facades of the FAB3R factory in Trois-Rivières, Quebec. The hourly unitary flow rate is set at 41 m3/m2 or 2.23 cfm/ft2 of collector area, at the lower range because only a limited number of intake fans was close enough to the solar façade to avoid long ventilation ductwork. Photo: Trigo Energies Quebec’s solar air heating boom: the Trigo Energies story Trigo Energies makes almost 90 per cent of its sales in Quebec. “We profit from great subsidies, as solar air systems are supported by several organizations in our province – the electricity utility Hydro Quebec, the gas utility Energir and the Ministry of Natural Resources,” explained Christian Vachon, Vice President Technologies and R&D at Trigo Energies. Trigo Energies currently has nine employees directly involved in planning, engineering and installing solar air heating systems and teams up with several partner contractors to install mostly retrofit projects. “A high degree of engineering is required to fit a solar heating system into an existing factory,” emphasized Vachon. “Knowledge about HVAC engineering is as important as experience with solar thermal and architecture.” One recent Trigo installation is at the FAB3R factory in Trois-Rivières. FAB3R specializes in manufacturing, repairing, and refurbishing large industrial equipment. Its air heating and ventilation system needed urgent renovation because of leakages and discomfort for the workers. “Due to many positive references he had from industries in the area, the owner of FAB3R contacted us,” explained Vachon. “The existence of subsidies helped the client to go for a retrofitting project including solar façade at once instead of fixing the problems one bit at a time.” Approximately 50 per cent of the investment costs for both the solar air heating and the renovation of the indoor ventilation system were covered by grants and subsidies. FAB3R profited from an Energir grant targeted at solar preheating, plus an investment subsidy from the Government of Quebec’s EcoPerformance Programme.   Blue or black, but always efficient: the advanced absorber coating In October 2024, the majority of the new 2,750 m² (29,600 ft2) solar façade at FAB3R began operation (see figure 1). According to Vachon, the system is expected to cover approximately 13 per cent of the factory’s annual heating demand, which is otherwise met by natural gas. Trigo Energies equipped the façade with its high-performance Calento SL collectors, featuring a notable innovation: a selective, low-emissivity coating that withstands outdoor conditions. Introduced by Trigo in 2019 and manufactured by Almeco Group from Italy, this advanced coating is engineered to maximize solar absorption while minimizing heat loss via infrared emission, enhancing the overall efficiency of the system. The high efficiency coating is now standard in Trigo’s air heating systems. According to the manufacturer, the improved collector design shows a 25 to 35 per cent increase in yield over the former generation of solar air collectors with black paint. Testing conducted at Queen’s University confirms this performance advantage. Researchers measured the performance of transpired solar air collectors both with and without a selective coating, mounted side-by-side on a south-facing vertical wall. The results showed that the collectors with the selective coating produced 1.3 to 1.5 times more energy than those without it. In 2024, the monitoring results were jointly published by Queen’s University and Canmat Energy in a paper titled Performance Comparison of a Transpired Air Solar Collector with Low-E Surface Coating. Selective coating, also used on other solar thermal technologies including glazed flat plate or vacuum tube collectors, has a distinctive blue color. Trigo customers can, however, choose between blue and black finishes. “By going from the normal blue selective coating to black selective coating, which Almeco is specially producing for Trigo, we lose about 1 per cent in solar efficiency,” explained Vachon.

Photo: Matrix Energy Matrix Energy: collaborating with architects and engineers in new builds The key target customer group of Matrix Energy are public buildings – mainly new construction. “Since the pandemic, schools are more conscious about fresh air, and solar preheating of the incoming fresh air has a positive impact over the entire school year,” noted Brian Wilkinson, President of Matrix Energy. Matrix Energy supplies systems across Canada, working with local partners to source and process the metal sheets used in their MatrixAir collectors. These metal sheets are perforated and then formed into architectural cladding profiles. The company exclusively offers unglazed, single-stage collectors, citing fire safety concerns associated with polymeric covers. “We have strong relationships with many architects and engineers who appreciate the simplicity and cost-effectiveness of transpired solar air heating systems,” said President Brian Wilkinson, describing the company’s sales approach. “Matrix handles system design and supplies the necessary materials, while installation is carried out by specialized cladding and HVAC contractors overseen by on-site architects and engineers,” Wilkinson added. Finding the right flow: the importance of unitary airflow rates One of the key design factors in solar air heating systems is the amount of air that passes through each square meter of the perforated metal absorber,  known as the unitary airflow rate. The principle is straightforward: higher airflow rates deliver more total heat to the building, while lower flow rates result in higher outlet air temperatures. Striking the right balance between air volume and temperature gain is essential for efficient system performance. For unglazed collectors mounted on building façades, typical hourly flow rates should range between 120 and 170 (m3/h/m2), or 6.6 to 9.4 cfm/ft2. However, Wilkinson suggests that an hourly airflow rate of around 130 m³/h/m² (7.2 cfm/ft2) offers the best cost-benefit balance for building owners. If the airflow is lower, the system will deliver higher air temperatures, but it would then need a much larger collector area to achieve the same air volume and optimum performance, he explained. It’s also crucial for the flow rate to overcome external wind pressure. As wind passes over the absorber, air flow through the collector’s perforations is reduced, resulting in heat losses to the environment. This effect becomes even more pronounced in taller buildings, where wind exposure is greater. To ensure the system performs well even in these conditions, higher hourly airflow rates typically between 150 and 170 m³/m² (8.3 to 9.4 cfm/ft2)  are necessary.

Photo: Conserval Engineering Solar air heating systems support LEED-certified building designs Solar air collectors are also well-suited for use in multi-unit residential buildings. A prime example is the Canary District in Toronto (see Figure 3), where single-stage SolarWall collectors from Conserval Engineering have been installed on several MURBs to clad the mechanical penthouses. “These penthouses are an ideal location for our air heating collectors, as they contain the make-up air units that supply corridor ventilation throughout the building,” explained Victoria Hollick, Vice President of Conserval Engineering. “The walls are typically finished with metal façades, which can be seamlessly replaced with a SolarWall system – maintaining the architectural language without disruption.” To date, nine solar air heating systems have been commissioned in the Canary District, covering a total collector area of over 1,000 m² (10,764 ft2). “Our customers have many motivations to integrate SolarWall technology into their new construction or retrofit projects, either carbon reduction, ESG, or green building certification targets,” explained Hollick. The use of solar air collectors in the Canary District was proposed by architects from the Danish firm Cobe. The black-colored SolarWall system preheats incoming air before it is distributed to the building’s corridors and common areas, reducing reliance on natural gas heating and supporting the pursuit of LEED Gold certification. Hollick estimates the amount of gas saved between 10 to 20 per cent of the total heating load for the corridor ventilation of the multi-unit residential buildings. Additional energy-saving strategies include a 50/50 window-to-wall ratio with high-performance glazing, green roofs, high-efficiency mechanical systems, LED lighting, and Energy Star-certified appliances. The ideal orientation for a SolarWall system is due south. However, the systems can be built at any orientation up to 90° east and west, explained Hollick. A SolarWall at 90° would have approximately 60 per cent of the energy production of the same area facing south.Canada’s expertise in solar air heating continues to set a global benchmark, driven by supporting R&D, by innovative technologies, strategic partnerships, and a growing portfolio of high-impact projects. With strong policy support and proven performance, solar air heating is poised to play a key role in the country’s energy-efficient building future.

In my last Fast Company column, I shared my reasons for manufacturing my electric trucks in the U.S. I’m not alone. While near-shoring to North America has been underway for several years, the current tariff shifts and shipping complexities make U.S. manufacturing a higher priority still. However, there were 292,825 factories in the U.S. as of 2021. Of those, 846 employ 1,000 people or more. Some of these are my engineering firm’s clients, giving us a front row seat to the complexity of retrofitting an existing factory to full U.S. manufacturing. While building a new factory is expensive and lengthy, these companies’ tasks are more difficult still. There are good reasons for making the shift as quickly as possible. Moving to most or fully U.S. manufacturing brings higher visibility, faster response time, and higher resilience to supply chain disruption, as well as greater protection from tariff shifts and geopolitical change. But if you’re early in the process, here’s my advice for your transition: Determine a priority ranking for the refining and raw materials you shift to in-country and North American sourcing. Give highest ranking to categories including defense, high value items (such as steel, aluminum, and rare minerals, etc.), and consumer safety items (such as pharmaceutical components, etc.). Be more strategic in the offshore suppliers you continue using for non-advanced manufacturing by prioritizing closer and more geographic-friendly locations for production and shipment such as Mexico and Argentina. Utilize government-backed capital, where possible, for extracting/mining minerals and metals such as lithium, red mud, magnesium, etc. Beyond the high-ranking product categories, move to domestic suppliers for primary materials such as steel, aluminum, cement, and plastics. Likewise, reduce offshoring of technical staff as well as raw materials, where possible. Use all means possible to become power independent through solar production, micro-grids, and nuclear power production. Consider creating a 4-year completion bonus for military vets. Hire vets wherever possible, as they make great workers and entrepreneurs. Likewise, we can press for future policy changes that best support Made in America manufacturing, as follows: Encourage ship building in the U.S., as well as creating new means of automated freight transit. Work towards transformation plans for government-funded R&D to include more attractive loans, rebates, and grants, as well as programs for tax-free status for intellectual property during commercialization, to incent and support organizations making the shift. Consider energy rebates to U.S. manufacturers and distributors to make American manufacturing more cost-effective and viable.   Create policies to include the cost of offshore staff in tariff calculations. Expand trade relationships with Caribbean nations for products such as sugar, avocados, bananas, etc. Avoid or even ban foreign ownership of the food supply chain. Create fair competition for government contracting. Make health supplements and homeopathic medicines tax deductible, to promote a healthy workforce. While it may not be readily evident, these policy changes are related to successful reshoring. In all, we need larger scale, lower costs, and more automated and simplified mechanisms for product manufacturing. These issues, in my experience, are as equally important as the raw materials we require. We need increased support for niche manufacturing. In my opinion, we also need deregulation, and increased access to land (particularly in the west; the federal government owns great quantities of the available land, which is choking available supply). I believe we need better education, self-reliance, health, and incentive structures to get the capital, entrepreneurs, and workers for Made in America manufacturing. Who’s with me?

A teen tech entrepreneur is working to retrofit robots with simulated artificial bodily functions like a virtual heart rate, body temperature, and sweating response — a bong-rip idea to make them better emulate human emotional states like joy or anxiety.In an interview with TechCrunch, the 19-year-old founder of "emotionally intelligent robots" company Intempus, Teddy Warner, explained why he's imbuing AI with digital versions of the often-uncomfortable sensations you feel during spells of heightened emotion like fear and anxiety.Warner told the website that he got the idea for his company while working at the AI image generator outfit Midjourney.During his time at that company, the researcher and his coworkers were tasked with building out a so-called "world AI" model, which essentially means an AI that makes decisions like humans do in the real world.While world models have made waves in the AI industry in recent years, they've fallen short because, as Warner puts it, they're being trained on data from robots that heretofore have lacked the kind of physiological feedback humans have."Robots currently go from A to C, that is observation to action, whereas humans, and all living things, have this intermediary B step that we call physiological state," he explained to TechCrunch. "Robots don’t have physiological state. They don’t have fun, they don’t have stress."For robots to understand our human world, they need "be able to communicate with humans in a way that is innate to us, that is less uncanny, more predictable, we have to give them this B step," he continued.In short, Warner thinks robots need to be able to feel like we feel. After hooking himself and his buddies up to polygraph tests to capture their sweat data, the youthful founder built out an AI model that can, as he told the website, "essentially allow robots to have an emotional composition" based on lie detector data.Depending on how much Kool-Aid you've had to drink, the concept of feeling robots — and AI trained on lie detector tests — is either goofy or terrifying. The latter vibe is worsened by Warner's recent announcement that he'd won a Thiel Fellowship, which the controversial tech billionaire Peter Thiel awards to several youngsters each year to fund their entrepreneurial dreams.Since September, Warner has built out the Intempus research apparatus and managed to sign seven partners in the process. He's now hiring staffers and working on testing his retrofitted feeling robots in front of customers — though he says he's not opposed to building his own robots in the future."I have a bunch of robots, and they run a bunch of emotions," he told TechCrunch. "I want to have someone come in and just understand that this robot is a joyful robot, and if I can innately convey some emotion, some intents that the robot holds, then I’ve done my job properly."Share This Article

Touchscreens were really cool 15 years ago, when the iPad first came out. Now that the novelty's worn off, more people seem to realize that navigating submenus sucks. Manufacturers, particularly automotive ones, love touchscreens because it reduces their production costs. But the user experience suffers for it, and leaves many craving physical knobs, buttons, dials and switches.A Bulgarian company called Enhance manufactures an aftermarket knob for the Tesla. In keeping with the puerility of the target market, it's called the S3XY Knob. The retrofittable knob, which comes in a housing flanked with four programmable buttons, communicates with the car via Bluetooth and Tesla's API. It's mounted in the center console and allows drivers to access the climate control, media playback, drive modes and more without needing to fuss with the touchscreen. Visual feedback comes via a small circular screen atop the knob.Here's a demo of what it can do:The company also makes standalone S3XY Buttons for Teslas that are user-programmable. They come with stickers of various functions. The knobs run about $450, and buy-in for the buttons starts at $330 for a four-pack.The question is whether these objects will proliferate, or if manufacturers will listen to customer feedback and give people the kinds of controls they actually like.

The chief executive of the developer Antracit discusses her ambitions for the contest contest to retrofit and upgrade the former Palace Hotel in Ostrava, Czechia Zuzana Bajgarová inside the Palace Hotel Credit: Image by Vladimir Prycek Magazine Patriot Why are you holding an international contest for the renewal of the Palace Hotel in Ostrava? The former Palace Hotel building holds great historical and cultural significance for Ostrava. Since 1913, it has been an integral part of city life – fondly remembered by several generations, whether as a venue for cultural and social events or as a backdrop to everyday urban life. That’s why we are approaching its renewal with the utmost respect and openness to diverse architectural perspectives. We believe that an international competitive dialogue is the most effective way to arrive at a high-quality, sensitive solution that also aligns with the expectations of investors. We view the project as one of our company’s flagship initiatives – one that will shape the future appearance of Ostrava’s historic centre, in the Czech Republic’s third-largest city. What is your vision for the future of this important city centre building? Our vision is to transform the Palace Hotel into a vibrant, open space that seamlessly integrates into the everyday rhythm of city life. We believe it can offer the kind of amenities and services that Ostrava currently lacks. We aim to develop stylish, small-scale rental housing, complemented by services, community spaces, and potentially even a modern lifestyle hotel. A key priority is revitalizing the building’s ground floor as a dynamic public space and thoughtfully incorporating historical features into its renewed identity. This is a long-term investment focused on sustainability and on creating lasting value – not only for the people of Ostrava, but for the city as a whole. What sort of teams would you like to see step forward for this unique opportunity? We would like to invite teams that think beyond the immediate task – those with the courage to approach this project with both respect and vision. We value interdisciplinary collaboration that brings together architecture, urbanism, design, and experience in the transformation of historic buildings. Equally important to us is an understanding of urban life and the ability to design spaces that serve people naturally and intuitively. We are seeking a long-term partner – someone who will accompany us from concept through to successful implementation, and help restore the Palace Hotel to its rightful place on the map as a vibrant, confident presence in contemporary Ostrava. 2025-06-01 Merlin Fulcher Share
