Nanofiltration reduces industrial chemical separation emissions

Spotted: An invisible polluter, industrial chemical separation is a necessity in many industries, including pharmaceuticals, oil refinement, and semiconductor and vegetable oil production. Accounting for up to 15 per cent of the world’s energy use, the process of separating chemicals for commercial and industrial use creates significant volumes of carbon emissions – possibly up to 10 per cent of the world’s greenhouse gases.

Seeking a way to reduce the environmental harm of those processes, Singapore-based Seppure built a membrane capable of separating even the harshest chemicals at the molecular level without using heat. Built with nanotechnology, the membrane is so strong yet porous at a nano level that it can be reused multiple times, in a wide range of temperatures, and remain resistant to degradation from the chemicals with which it comes into contact.

Importantly, the membranes can be used throughout the processes of separation, from distillation to evaporation, without heat at any stage. By removing the need for high temperatures, the new membranes conserve water while also reducing carbon dioxide emissions.

Resource conservation and energy conservation are key aims in every industry. Springwise is spotting an exciting mix of initiatives that tackle these goals, from magnetic levitation for frictionless motors, to a new method for extracting lithium that recycles water and brine.

What Can North Americans Learn About Design From European Cities?

Judging is now underway for the 10th Annual A+Awards Program! Want to earn global recognition for your projects? Sign up to be notified when the 11th Annual A+Awards program launches. 

As a Canadian ex-pat currently living in France, I was excited for and whole-heartedly welcomed a change of pace from North American life. Canadians and Americans often idolize Europe and its accompanying lifestyle, and after nine months in France, I can confirm the charm of European living has yet to wear off.

Europe covers a relatively small landmass, especially when comparing it to the rich array of countries that make up the continent. Each country offers its own distinctive culture and way of life, and because of this, it is difficult to categorically define ‘European living.’ Nonetheless, there are certain cultural similarities that can be strongly felt amongst countries (especially those in Western Europe). I will use my time residing in France as a case study to help make sense of North America’s infatuation with the European lifestyle. An infatuation that I continue to feel here in France.

I’ve been residing in Orléans, a small French city located one hour southwest of Paris. The city dates back to antiquity and has a charming mix of half-timbered medieval homes, Haussman-style buildings and Gothic architecture. Those living in the city center typically reside in the town’s older infrastructure, while those in the surrounding suburbs occupy newer, more contemporary buildings.

One of the most apparent reasons why North Americans are so charmed by Europe is its history. European cities are filled with an incredible history that is recognizable through architecture. As a North American, it’s hard not to be taken by such ornate and historic surroundings. When living in Orléans, I can confirm that walking past the striking gothic cathedral and rows of half-timbered homes never got old to my North American eyes.

Despite such apparent beauty, history and charm, there were certain aspects of French living that took some time to get used to. While in France, I said goodbye to the many North-American luxuries I had grown accustomed to: high-end heating, accessible infrastructure, dryers and large living spaces. At first, I missed such luxuries but I quickly discovered just how easy it is to live without them. All it took was a bit of adjusting to eventually realize that many North-American amenities are superfluous. In the winter months, I learned to layer my clothes and in the summer months, I made sure to keep my shutters closed during the day. Quickly enough, giving up modern amenities was easy to do when, in return, you get to live in a historic city.

Even as we enter the hot summer months, I do not long for North American amenities. One of the most pronounced differences between Europe and North America in the summer is the absence of air conditioning. Most old European apartments do not come equipped with air conditioning. European homes are often built with brick and stone, unlike North American homes, which are built with wood. Building with stone and brick provides much better insulation and thus a more temperature-regulated living space. Therefore in Europe, it is possible to keep a dwelling cool in the summer. Moreover, the use of exterior window shutters is common in Europe and helps keep out the heat during the days and ventilate the home at night. Perhaps it is less convenient not having air conditioning, but the traditional building infrastructure makes it possible to endure hot summers.

Moreover, I realized that Orléans’ architecture contributed to my ability to find community in a foreign country. For example, the tight living spaces and communal courtyards helped foster strong connections with my roommates and neighbors. Equally, the abundance of mixed-use buildings furthered this strong sense of community living. In North America, we are often used to separate residential and commercial districts. Whereas in Europe, everything is much more densely organized. We often perceive density as a negative urban characteristic, but in this case, it helped me find my place and personal rhythm in Orléans. Whether it was visiting my local boulangerie or pharmacie, the intertwined nature between commercial stores and residential dwellings fueled a strong connection between all Orléanais people. In addition, the numerous public squares sprawled throughout the city would hold weekly farmer’s markets and social events. These public squares further contributed to my ability to comfortably integrate into the local way of life.

Before I knew it, the very things I at first disliked about France became the very aspects I now appreciate. Today I see claustrophobic close quarters as intimate spaces, narrow sidewalks as endearing and the bike-unfriendly cobblestone roads as a welcomed challenge to my daily commute to work. All in all, what I’ve taken away from my time in France is that European living is often more laidback. It’s at times less convenient and less polished but equally, if not more, enjoyable to North American life. The homes may not be equipped with the standard appliances found in North America, however, one will quickly find great satisfaction and purpose in navigating the quirks of European life.

A CSR platform enables companies to choose and track verified impact projects

A CSR platform enables companies to choose and track verified impact projects

Spotted:  Investors and corporates alike are increasingly interested in using software as a service (SaaS) models to integrate sustainability-focused infrastructure into corporate platforms. In line with this trend, Singaporean startup Handprint is providing businesses with an easy way to improve their planetary impact. 

The Handprint platform offers companies a choice of pre-verified impact projects grouped into themes such as social justice, clean water, and deforestation. Each company can then choose to support the ones that best align with its brand and values.  

Once a company has chosen the projects it wishes to support, software plugins integrate contributions to those projects into core business functions such as e-commerce. For example, food delivery company Saladstop integrated with Handprint’s technology to allow its customers to order ‘climate positive’ meals. Similarly, media platform Teads worked with Handprint to let its users dedicate part of their advertising spend to the regeneration project of their choice.  

The idea behind Handprint is that the company makes the contribution rather than the end consumer. But by using Handprint’s platform, companies gain benefits such as increased brand loyalty and greater cart conversion, while also linking their impact contributions to their core business. 

Handprint also makes it easy to track the company’s overall contribution – both in terms of monetary investment and impact outcomes. The progress of the company’s chosen projects can be traced with quasi-real-time data and on-the-ground photos – which the company can post on social media. 

A really important benefit of Handprint’s approach is that it significantly reduces intermediary costs on the back-end. By using blockchain technology and satellite imagery Handprint is able to avoid some of the costs normally associated with donation-based systems. As a result, more money flows to projects on the ground and less to third-party administration. In fact, the company claims to have one of the best dollar-to-impact rates in the world, being on average 68% cheaper than its competitors. 

In a crowded marketplace for corporate impact, Handprint’s credibility is boosted by its links with academia, and the financial backing it has recently received through a $2.2 million (around €2.08 million) funding round. 

Other recent software innovations aimed at corporate sustainability include a platform for measuring an organisation’s IT footprint, a SaaS platform that helps real estate investors lower their environmental impact, and a platform that simplifies ESG data.

10 Architectural Photographers Who Dominate the Field

Send us a photo. Tell us a story. Win $2,500! Architizer’s 3rd Annual One Photo Challenge is underway with an Early Entry Deadline on May 27, 2022! Start your entry for architecture’s biggest photography competition here.

Architectural photography has forever changed the way we understand design. As images have become ubiquitous, their influence on culture and society can be felt throughout the world. Over the last thirty years, we’ve transitioned from discovering architecture primarily through individual experience and print to seeing buildings through renderings and photography. This has created an opportunity for architectural photographers to help designers see their work in a new light and utilize a photographer’s eye for structure, light and form.

Enter One Photo Challenge

Taking three-dimensional space and making it two-dimensional, architectural photographers build off their understanding of both their subject and the mediums by which their work will be shared. Focusing on composition and narrative, their images use buildings to tell a story. At the same time, photographers balance the need for the accurate representation of a structure and how it connects to a larger place. Showcasing the individuals shaping the image of architecture, the following photographers capture design from a range of perspectives. Together, they give a glimpse into how we discover architecture.


Roberts Pavilion, Claremont McKenna College by JFAK Architects, Images by Fotoworks/Benny Chan

Benny Chan lives in Los Angeles and works as both an art and commercial photographer. Through architecture and photography, Benny Chan makes sense of the world; he is fascinated by how things go together. His photographs may collectively be read as an assembly manual for Los Angeles. They show the city from top-down perspective, as plan-views of its infrastructures and everyday monuments. They get inside the machines that run the metropolis, from the port of Los Angeles, to utility stations, transportation terminals, warehouses, and laundromats. They all have powerful stories.

Chan’s efforts to make sense, to figure out, shapes his work. He hangs from helicopters to get the right angle. He builds his own cameras to surpass focal length limitations of off-the-shelf models. And, he finds his way behind the scenes and into highly restricted sites.


Elbphilharmonie Hamburg by Herzog & de Meuron & L’Arbre Blanc Residential Tower by Sou Fujimoto, Photographs © Iwan Baan

Iwan Baan is a Dutch photographer known primarily for his images that narrate the life and interactions within architecture. Born in 1975, Iwan grew up outside Amsterdam, studied at the Royal Academy of Art in The Hague and worked in publishing and documentary photography in New York and Europe. Iwan fell unexpectedly into the subject of architecture in 2005 when he proposed to document a project by OMA to Rem Koolhaas, leading to his first major project, the documentation of the construction of OMA’s China Central Television (CCTV) building.

Today, Iwan collaborates with some of the world’s most well-known architects, photographing institutional, public and private projects. His work is characterized by the portrayal of the context, society and environment around architecture.

Hufton + Crow is a UK-based photography studio that was founded by Nick Hufton and Allan Crow. The duo work as a team and have captured contemporary interior and exterior architecture for renowned practices. Nick and Allan grew up together in Macclesfield, northern England, before moving to London. Both trained in analogue using a large format camera favored by many architectural photographers, but switched to digital as soon as the opportunity arose. The technical possibilities of digital photography mean it is now possible to stitch together several images to show wider views or to combine a series of moments into one. Harnessing these strategies has led the team to earn further commissions.

Raised in Hong Kong, Thom moved to California in the mid-1960s and trained in the technical craftsmanship of photography. He is adept at harnessing natural light for both interior and exterior compositions. For more than thirty years Thom has captured the surfaces and depths, the shapes and textures, the contrasts and reflections of the objects of the built environment.

A patient reveler in the natural staging of the atmosphere, he creates compositions of materials around color and glow. Thom’s still life depictions unveil an idealized portrait of the inhabitable world, exposing the ultimate ambition of the architectural work as that which renders existence as art.

Mike Kelley is an architectural photographer from Los Angeles, California. He grew up in Ipswich, Massachusetts, and after studying studio art and environmental science at the University of Vermont, he eventually found himself taking up an offer to photograph a few homes for a client.

What started by chance turned out to be a mix of technical challenge and creative outlet. In 2018, he founded the Architectural Photography Almanac, a resource for architecture photographers and those in the architecture industry seeking to learn about the craft and theory of architectural photography.


Kaufmann House by Richard Neutra & Stahl House by Pierre Koenig, Photography Courtesy Julius Shulman Photography Archive

No discussion of architectural photographer can be had without mentioning Julius Shulman. His career as an architectural photographer began in 1936 when he showed Richard Neutra some photographs he had made of the architect’s Kun Residence in Los Angeles. Neutra liked the images and asked Shulman to photograph more of his houses for him.

Ultimately, Shulman photographed most of Richard Neutra’s work and was introduced to other modernist architects working in Southern California. His extraordinary client list eventually included: Charles and Ray Eames, Raphael Soriano, John Lautner, Pierre Koenig, Rudolf Schindler, Frank Lloyd Wright and hundreds of others. Shulman did not merely document significant architecture, but interpreted it, becoming one of the most important and influential architectural photographers in history.

A wood-based cooling foam could improve energy efficiency

A wood-based cooling foam could improve energy efficiency

Spotted: As global temperatures continue to rise, the demand for air conditioning is skyrocketing. In fact, according to a recent study, the use of air conditioners is expected to quadruple by 2050. This increased demand will not only strain the world’s energy resources – it will also contribute to greenhouse gas emissions. In response, engineers in China and Germany have designed a new type of foam made from wood-based cellulose nanocrystals. 

The new foam is lightweight and reflective, meaning it can deflect solar radiation and allow heat to escape. The material is also thermally insulating. In fact, during trials the material reflected 96 per cent of sunlight and emitted over 90 per cent of the infrared radiation absorbed. If widely adopted, this technology could help to reduce the cooling energy needs of buildings by more than a third. As the world looks for ways to mitigate the effects of climate change, this foam has the potential to be a game-changer. 

When placed over an aluminum foil-lined box, the researchers found that the material was able to keep the temperature inside the box 16 degrees Fahrenheit cooler than the outside. And when the air was humid, the material kept the inside of the box 13 degrees Fahrenheit cooler. The team estimates that placing the foam on the roof and exterior walls of a building could reduce its cooling costs by up to 30 per cent. So far, the material has only been tested in small spaces. But if it can be scaled up to commercial applications, it could provide a much-needed break for our overburdened air conditioners.

The researchers believe the foam can be adapted to work in a wide range of environments, making it an ideal solution for a variety of applications.  

The study also provides an important proof of concept for the use of cellulose-based materials in thermal management, and it is hoped that this technology will eventually lead to significant reductions in energy consumption. 

Other recent heating and cooling innovations spotted by Springwise include a smart building management system that heats and cools offices as needed, a smart roof coating for better energy saving, and a window coating that blocks infrared light.

The world's first cell cultivated leather

The world’s first cell cultivated leather

Spotted: As the world becomes increasingly aware of the ethical and environmental issues associated with traditional leather production, companies and retailers are on a mission to find high-quality leather alternatives. Lab-grown meat has received a lot of attention, with several companies’ products expected to hit the shelves in 2022 and 2023. Now, another startup is in position to scale up the production of lab-grown leather.

Vitrolabs is developing a process that can efficiently produce leather from only a few cells in an environmentally friendly way. This process involves taking a biopsy—a one-time collection of cells—from a live animal. These cells are then grown in a nutrient-rich environment – dividing and forming into tissue that can then be turned into leather. The composition of the material produced through this process achieves the complexity of traditional hides. This addresses a problem often levelled at other leather alternatives – that consumers crave the luxurious quality of real leather.

Last autumn, the company expanded into a new facility to pilot production, and as the company makes its way to commercialisation, it has received $46 million (around €43 million) in a new round of funding.

“There has been an explosion of companies that are developing alternative materials to leather,” explains VitroLabs CEO Ingvar Helgason. “At VitroLabs, our cultivated animal leather preserves the biological characteristics that the industry, craftsmen, and consumers know and love about leather, while eliminating the most environmentally and ethically detrimental aspects of the conventional leather manufacturing process associated with its sourcing.”

Many innovators are developing leather alternatives made using materials such as apples, hemp, and grape waste. However, VitroLabs is the first innovator spotted by Springwsie that is taking a lab-grown approach to sustainable leather.

A Lakeside Summer Home Rebuilt on the Path to Zero
CategoriesSustainable News Zero Energy Homes

A Summer Home Rebuilt on the Path to Zero

The blue cottage in a historic Chautauqua community in Lakeside, Ohio, had hosted families for nearly a century and had been the beloved summer getaway of Frank and Brenda Baker’s family for the past 15 years. So when a tree fell on their summer home in June 2009, it crushed more than just the structure. At first, the Bakers hoped to save some of the original building, but a thorough inspection determined that even the areas that didn’t take a direct hit were too compromised to be reused. That news prompted the Bakers’ plan B: to rebuild the cottage from the ground up as a model of energy efficiency and sustainable building while maintaining the character of its 100-year-old  predecessor. To that end, they hired both a designer and a builder experienced in both sustainability and historic preservation.

Frank and Brenda have christened their project “The Lakeside Green Cottage” and have engaged like-minded professionals to bring it to life. Their designer, Dennis Feltner is an advocate for eco-friendly design and plans to adapt the sustainable building principles used in this home into his future work.  Additionally, the construction contractor, Tom Dearth, is a Certified Green Builder through the National Association of Homebuilders. Partnering with the  Lakeside Association’s sustainability initiative, the Lakeside Environmental Stewardship Society, the Bakers host tours of the cottage to help educate the public about the value of green renovations. “We want to show people that eco-friendly building technology and historic character can go hand-in-hand,” Frank Baker said. 

“We really think this will be an asset to the community, and perfectly aligned with the Lakeside spirit and mission, he adds. 

Sustainable Building  Measures

The Baker cottage incorporates timber frame construction, with visible posts and beams used on the first floor.  Timber trusses support the roof and create vaulted ceilings in the second-story bedrooms. They used structural insulating products for the shell of the house, incorporating structural insulating panels (SIPs), insulating concrete forms (ICFs), and flexible EPS insulation sheets. The result is a super-tight building envelope that keeps conditioned air in, vastly reducing energy use – and energy bills.

In keeping with the Baker’s sustainability goals, materials from the original cottage were reused wherever possible, including the staircase, banister, and spindles; beadboard paneling; red pine floor planks; interior doors; bathroom fixtures, and some kitchen cabinets.

Products Used

PFB® insulating building products were used throughout the Lakeside Green Cottage. The high insulating properties of the products are due to their primary component, expanded polystyrene  (EPS), a rigid foam material that has special properties due to its structure. The individual cells of low-density polystyrene make EPS extremely light and strong, able to support many times its own  weight. The individual cells prevent heat and air from moving through the EPS, making it a great insulator. 

 

Advantage ICFs were used for the foundation of the cottage. These insulated concrete forms are interlocking blocks of EPS insulation with a void in the center. Once the blocks are in place and are filled with concrete, they create a poured, insulated foundation in one step. The ICF  blocks remain in place, isolating the concrete and preventing temperature conduction from the outdoors. Plasti-Fab Durofoam flexible insulation was installed beneath the basement floor, working in concert with the ICFs to create an unbroken “envelope” below grade. The foundation walls have an R-value of 23 and the floor is R15.

 

Insulspan SIPs are an “insulation sandwich” made of two sheets of structural oriented strand board (OSB) laminated to a continuous core of expanded polystyrene insulation (EPS). The resulting panels were used for walls and roofs, allowing the structure to be erected and insulated in one step. The span of solid insulation left no room for air movement, vastly improving energy efficiency compared to traditionally framed construction methods. The vaulted ceiling had an R-value of 38. And the whole home had 1.5 Air Changes per Hour.

Structural Timbers 

Timber framing, a centuries-old construction method, uses visible timbers as the building’s structural  “skeleton.” Timber framing requires less wood than conventional construction and makes use of a renewable resource. In addition, harvesting mature, healthy trees for this purpose ensures that the CO2 the wood has absorbed stays put, rather than being released back into the atmosphere. 

Riverbend Timber Framing created the visible posts and beams that were used on the first floor, with timber trusses supporting the roof and creating vaulted ceilings in the second-story bedrooms. 

The timber was forest salvaged Douglas Fir from fire-damaged forests and thus contributed further to the sustainability of the construction.

The Home Energy Rating 

The Bakers were committed to excluding fossil fuels from their summer home. So they used electric baseboard heat, electric hot water, and an electric stove, so they no longer use natural gas in their home; and when their local grid moves to renewable energy they will be totally fossil fuel free. Because it is a summer home they initially decided that it was not cost-effective to invest in heat pump HVAC or heat pump water heating. Nonetheless, this super airtight and highly insulated 2,479 square foot home qualified for the  NAHB’s National Green Building Standard certification at the Emerald level – the program’s highest and most demanding certification, which requires a  high level of resource and energy efficiency. The original HERS rating was 68 based on projected year-round use. 

Improving the HERS Rating

Several years after the home was completed in 2010, the Bakers replaced the baseboard electric heating with heat pump mini-splits and plan to replace the standard electric water heater with a heat pump water heater. And they are planning to have their energy consultant conduct blower-door-directed air sealing to check for and remedy any air leaks that may have occurred due to settling over the last 12 years. Then they will obtain another HERS rating. They are projecting that these energy upgrades will lower their energy use significantly and they are projecting receiving a HERS rating below 50 – qualifying the home for zero energy ready status.

Zero Energy Ready

For a home to qualify as zero energy ready it must have a HERS rating of 50 or less and be capable of having all its energy needs met by renewable rooftop solar.  While the Baker’s home is designed with roof orientation, area, and slope sufficient to enable rooftop solar, adding solar panels would not be cost-effective since it is not a year-round residence. Nonetheless, the Zero Energy Ready Home status ensures that energy costs will be very low and that its operational energy use will have a minimal carbon impact. With these new ratings, the Bakers plan to continue using their home and their more recent energy-efficient upgrades to educate and inspire others to get their homes on the path to zero through the Lakeside Environmental Stewardship Society (LESS) of Lakeside Chatutauqua.

A rooftop garden helps keep rickshaw cool

Spotted: There are around 95,000 registered auto-rickshaws in New Delhi. The colourful vehicles tend to blend in to the landscape. But one vehicle stands out – the rickshaw owned by Mahendra Kumar. The rickshaw driver has installed a garden on the vehicle’s roof – planted with more than 20 types of plants.

Kumar is hoping that the mobile rooftop garden will help keep the interior of his vehicle cool. In fact, he came up with the idea two years ago, during the peak of the summer season. Due to global warming, temperatures in New Delhi have been rising, at times exceeding 45 degrees Celsius, and last year saw India’s highest average maximum temperatures in 122 years. Against this backdrop, any relief would be welcome.

To create his garden, Kumar first laid a thick sack onto the rickshaw roof as a base, then added soil and seeds. He simply waters the plants from a bottle a few times a day. Not only does the garden provide a natural cooling effect, but it also gives residents a nice break from New Delhi’s ubiquitous concrete.

Indian taxi drivers are not the only ones who have converted cabs to gardens. At the height of the coronavirus pandemic in 2020, when tourism in Thailand had collapsed, the Ratchapruk Taxi Cooperative in Bangkok began growing vegetables on the roofs of idled taxi cabs, and farmed frogs in piles of abandoned car tyres. The vegetables and frogs helped to feed out-of-work drivers and the surplus was sold for extra income.

As the world heats up, innovative ideas like these are going to be important in mitigating the danger. Some other ideas for mitigating the heat island effect that we have seen recently include a platform that assesses urban heat island effects and designs solutions and the use of living roofs on large buildings.
