Spotted: Wood has been used in construction since time immemorial. However, more recently wood fell out of favour as a building material, both because it was seen as less safe and less sustainable. But the development of technical wood has demonstrated that it can not only be safer than other materials, but more sustainable as well. In Spain, startup Woodea is working to demystify the use of wood as a building material.
Woodea is combining wood, an ancient construction material, with modern production systems to deliver sustainable construction at a faster speed and comparable cost to traditional methods and materials. Its projects use technical wood, which is wood that has undergone high pressure and high temperature treatment to render it more durable. It also has better technical performance than materials such as concrete and steel.
Woodea has completed an initial funding round worth €1.4 million, with support from investors in a number of areas, including construction, engineering, and financial services. The capital will be used to undertake Woodea’s first projects, including construction of 250 wooden homes.
Architects and designers are increasingly rediscovering the advantages of building with wood. Springwise has also spotted a 100-metre tall, all-timber building being planned for Zurich, and a process that allows manufacturers to 3D print a wood composite.
A chair that can adapt over time and one fabricated with 3D-printed liquid metal are among the designs that students at MIT came up with for The Next 150-year Chair exhibition in collaboration with furniture brand Emeco.
In total five pieces were created for the exhibition, which was a collaboration between American furniture company Emeco and the Massachusetts Institute of Technology (MIT) to conceptualise sustainable furniture pieces.

Called The Next 150-year Chair, the project was carried out via a course at MIT that guided students through a design process with access to Emeco’s manufacturing technology.
The prompt was based on Emeco’s 1006 Navy chair developed in 1944, which has a “150-year lifespan” according to the company.
“Today, a 150-year chair means making something that lasts a long time, which is a great thing to do,” said MIT associate professor Skylar Tibbits. “But the question is whether that will be the same for the next 150 years – should the goal still be to make things that last forever?”
“That’s one approach, but maybe there’s something that could be infinitely recyclable instead or something that’s modular and reconfigurable.”
The students took a variety of approaches to the prompt. Photo of Faith Jones’ Rewoven Chair
The students each took a different approach to answering the question, and the results featured a number of complete furniture pieces and components.
Masters student María Risueño Dominguez developed a furniture component based on longevity. Her research on furniture consumption and interviews with people involved in the furniture industry resulted in a concept called La Junta – a cast-aluminium joint with multiple different inserts shaped to fit a variety of components.
Plastics, textiles and metal were used for the designs. Photo of María Risueño Dominguez’s La Junta
Other designers took a materials-focused approach when addressing the prompt.
Amelia Lee, a student at Wellesley taking courses at MIT, developed a product made from a single sheet of recycled HDPE. Modelled on a rocking chair, the piece can be turned on its side to function as a table.
“This chair can last through childhood, from crawling around it to being able to turn it over and play with it,” said Lee.
Zain Karsan took a different approach by aiming to improve metal 3D printing technology for the frames of his chairs.
“This process is an alternative to the slow process rates of traditional metal additive manufacturing wherein molten material is dispensed at high speed in a bed of granular media,” said Karsan. “A series of chair typologies are presented as a proof of concept to explore form and joinery.”
The projects accounted for style as well as longevity. Photo of Zane Karsan’s Liquid Metal Design
Faith Jones wanted to create a product that did not sacrifice comfort in a search for sustainability. Her ReWoven chair is designed with an aluminium frame and a recycled cotton sling, weaving the fabric around the aluminium skeleton in a way that would allow for the removal and replacement of the cotton.
Finally, designer Jo Pierre came up with a product aimed at the changes that will likely come as cities grow and become denser. Called Enhanced Privacy, the product is a plastic partition designed for domestic spaces. The hanging sheet of plastic can be filled with water in order to block sound and diffuse light.
The students’ projects were exhibited at Emeco House, the company’s event space in Los Angeles in a converted 1940s sewing shop.
Other exhibitions that push the boundaries of sustainability and novel materials include one in Mexico in collaboration with Space10 with five uses for biomaterials.
MIT has released a number of conceptual designs addressing sustainability including a project that tests the capability of tree forks as load-bearing elements in architectural projects.

Spotted: Our reliance on unclean energy sources has catapulted our planet out of stability and into an era of change. Across the globe, fossil fuel usage accounts for 65 per cent of the carbon emissions. But, as the French startup INOCEL aims to prove with its new high-performance hydrogen fuel cell, we can transition our fossil-fuel dependence onto cleaner energy sources.
INOCEL’s very high-power PEMFC, or proton-exchange membrane fuel cell, betters the competition in a few ways. First and foremost, it is three times more powerful than others its size on the market. On top of that, the company claims the product has an energy efficiency level of 60 per cent and a durability performance that makes operating costs more attractive. Finally, its battery size and volume are smaller than other PEMFC fuel cells.
By focusing its applications on fuelling marine, ground transportation, high-performance cars, and stationary applications, INOCEL’s technology will hopefully enable the startup to have a visible impact on a scalable level.
The company will make its unrivalled hydrogen fuel cell available in a 300-kW format in 2024.
Springwise has previously spotted other innovations aimed at making hydrogen power a more accessible energy source, including a startup that’s developed a way to increase the storage capacity of hydrogen, and a system that produces hydrogen on-site to avoid transportation and storage challenges.
British airline EasyJet and engineering company Rolls-Royce have run a commercial aircraft engine on hydrogen in what they claim is a “world first”, potentially paving the way for the decarbonisation of plane travel.
The companies trialled the engine in a ground test at the UK Defence Ministry’s Boscombe Down aircraft testing site using renewably-made green hydrogen and a converted Rolls-Royce AE 2100 – a regional aircraft engine.
The engine is considered an early concept demonstrator, so the technology is still in its infancy. But both Rolls-Royce and EasyJet say they are committed to proving that hydrogen can be a safe and efficient zero-carbon fuel for civil aviation.
Rolls-Royce has converted one of its aircraft engines to run on hydrogen
“The success of this hydrogen test is an exciting milestone,” said Rolls-Royce chief technology officer Grazia Vittadini.
“We are committed to continuing to support this ground-breaking research because hydrogen offers great possibilities for a range of aircraft,” added EasyJet CEO Johan Lundgren. “That will be a huge step forward in meeting the challenge of net zero by 2050.”
The test, which the companies claim was a “world first”, used green hydrogen supplied by the European Marine Energy Centre and created with the help of wind and tidal power in Scotland’s Orkney Islands.
This renewable electricity was used to power an electrolyser, which separates hydrogen from water in a process called electrolysis.
It was produced in partnership with EasyJet
To maximise the amount of hydrogen that fits into a tank, the gas is compressed to a pressure of 200 bar – equivalent to around 200 times the atmospheric pressure on Earth.
Rolls-Royce’s AE 2100-A engine was converted to combust this hydrogen instead of conventional fossil fuel-derived kerosene.
Rolls-Royce and EasyJet now plan to analyse the test data to improve their understanding of how to handle and operate hydrogen as an aviation fuel.
The partners are also planning future tests, starting with further ground tests before they move on to carrying out test flights.
They also plan to bring in a jet engine, the Rolls-Royce Pearl 15. This is more powerful than the AE 2100-A, which is generally used for smaller turboprop planes.
As signatories of the United Nations’ Race to Zero campaign, both Rolls-Royce and EasyJet are committed to achieving net-zero emissions by 2050 in an effort to keep global warming below the crucial threshold of 1.5 degrees Celsius.
The engine was tested at a military facility in the UK
Coming up with an alternative aviation fuel is a huge challenge for airlines, which currently contribute about 2.5 per cent of global CO2 emissions.
Green hydrogen is seen as a possible solution because it is made using renewable resources – green energy and water – and theoretically could see planes emit only water when used as a fuel.
There are several potential ways to use hydrogen in an engine, including as a liquid rather than a gas and as a fuel cell rather than through combustion.
However, critics have doubts whether jet planes will ever have the capacity to carry as much hydrogen as is needed to make their long journeys, and it is likely that aircraft would need to be quite heavily redesigned.
Several small hydrogen-powered aircraft have already flown, including those from aircraft developer ZeroAvia. Among the large airlines, Airbus is also pursuing the use of hydrogen, and in 2020 revealed three concepts for future aircraft powered by liquid hydrogen.
Rolls-Royce Holdings is the world’s second-largest maker of aircraft engines after General Motors and revealed its net-zero strategy in 2021. The company is separate to Rolls-Royce Motor Cars, which is wholly owned by the BMW Group.
Spotted: Glaucoma is a common condition where the optic nerve, which connects the eye to the brain, becomes damaged. This is often caused by fluid building up in the front part of the eye, which increases the pressure inside. It affects more than 80 million people worldwide. While it’s not possible to reverse any loss of vision that occurs before diagnosis, treatment can prevent further degeneration. And now, startup BVS Sight Inc. hopes to speed up diagnosis with a smart contact lens.
BVS was established to take advantage of technology developed by a Purdue research team. The team was led by Chi Hwan Lee, an Associate Professor of Biomedical Engineering at the Weldon School of Biomedical Engineering, and created smart contact lenses that can continuously monitor intraocular pressure (IOP) in the eye. This is the only known modifiable risk factor for glaucoma.
Previous wearable tonometers, which are devices that measure the pressure inside the eyes, use an integrated circuit chip. This makes the lens thicker and stiffer, and more uncomfortable, than typical soft lenses. Lee’s team gets around this by building on commercial brands of soft contact lenses to allow continuous 24-hour IOP monitoring, even when the wearer is asleep.
Health technology is rapidly advancing. Springwise has also spotted ultrasound stickers that monitor organ function, and self-powering wireless “skin” that can monitor various stimuli.
The fear of being called out for “greenwashing” is paralysing designer-makers into doing nothing on the climate crisis. It’s time to let them make mistakes, writes Katie Treggiden.
“Carbon washing is the new greenwashing”; H&M called out for “greenwashing” in its Conscious fashion collection; “Greenwashing won’t wash”: all Dezeen headlines from the past few years. In fact, the last one was mine. And it’s important that we call out greenwashing – the practice of making false environmental claims in order to sell products, services or policies.
With 66 per cent of all shoppers – rising to 75 per cent among millennials – saying they consider sustainability when making a purchase, the reward is clear. But making products and services truly environmentally responsible takes time, money, and effort, and the road to get there is full of nuance, compromises and trade-offs – none of which makes for easy profits or simple advertising slogans, so companies lie, exaggerate and bend the truth to scoop those sales.
It’s important that we call out greenwashing
Advertising and sales are hardly known for being bastions of honesty, but greenwashing’s harm goes beyond simply misleading consumers into buying something they didn’t want. All the time, money, and effort invested into these practices is not being spent on actually becoming more sustainable, and companies are let off the hook. Meanwhile, the misled customers are not investing their money in the companies that are sincerely trying to do things better.
“Greenwashing perpetuates the status quo because it leads specifiers, end users, everyone in the chain to believe that they are doing better than they actually are from a sustainability point of view,” said founder of content marketing agency Hattrick, Malin Cunningham. “Equally, the businesses doing the greenwashing have no incentive to improve.”
However, all these “greenwashing” headlines are striking fear into the hearts of designers, makers, interior designers and architects who want to do the right thing, but haven’t quite got it all worked out yet. In a poll of my community of designer-makers, 100 per cent said that fear of getting it wrong had stalled progress on sustainability-driven projects.
Cancel culture and call-out culture are particularly prevalent on social media, which often lacks the nuance for proper discussions about environmentalism and yet, those are the very spaces in which small creative businesses are promoting their products and services.
All these “greenwashing” headlines are striking fear into the hearts of designers
The importance of failure in creativity is well documented. There’s the 5,126 failed prototypes James Dyson went through before finally cracking the technology behind his eponymous vacuum cleaner, the Thomas Edison quote: “I have not failed 700 times. I have succeeded in proving that those 700 ways will not work”, and the fact that Walt Disney’s first film company went bankrupt before he turned 21. But perhaps we’ve heard these kinds of stories so many times that we’ve forgotten what they mean.
In his book Atomic Habits, James Clear gives the example of a cohort of film photography students at the University of Florida. Their professor divided them into two groups. One would be graded solely on the quantity of photographs they produced – the more pictures, the higher the grade, no matter how good they were. The second group need only submit one photograph, but it would be judged on quality – to get an A, it needed to be near-perfect.
The result? The better photographs came from the first group, the group being judged on quantity alone. The moral of the story here is that in order for creative people to succeed, they need to be given permission to fail. Or put another way, holding them to a standard of near-perfection doesn’t create the conditions for success.
“The only way that we’re going to be able to tackle the huge challenges that humanity is facing is by trial and error,” said Cunningham. “Small independent businesses are very well placed to help find these solutions and it’s essential that they are allowed to experiment without being hung out to dry in the process.”
It’s important that we encourage imperfect progress, that we recognise honest intent
The difficulty is that the main difference between greenwashing and honest but imperfect progress is intent, and that can be difficult to discern. For designers and makers, Cunningham recommends transparency in communications.
“It is about having clarity around the environmental impact you’re making as a business and what your goals are – and then being transparent about where you are on your journey towards achieving those goals,” she said. “It means taking action first and communicating second.”
And what about those of us writing those headlines? It is, of course, crucial that journalists “speak truth to power” and continue to call out companies that are knowingly making exaggerated or outright false environmental claims.
But it’s also important that we encourage imperfect progress, that we recognise honest intent and that we ask the right questions to make sure we can tell the difference. In our coverage of sustainable design, we need to celebrate the journey as well as the destination.
We need to let designer-makers get sustainability wrong, so that they can get it right. All our futures depend on it.

Spotted:Small power refers to unfixed electrical equipment, products, and appliances, commonly plugged into the electricity network. In an office environment, there may be thousands of these devices left turned on 24/7, and they can account for up to 40 per cent of energy usage. Yet, it is not practical to go around turning these devices on and off all the time.
To lower the energy usage of small power, startup measurable.energy has developed a smart socket designed specifically for commercial use that incorporates machine learning to automatically measure and eliminate small power waste. The sockets work like a normal socket but contain software that can automatically identify devices plugged into the sockets, monitor their energy use, report granular real-time data, and automatically turn devices on or off to avoid wasted energy.
The sockets can measure the exact usage of small power energy per socket, showing when and where energy is in use or wasted. Organisations can then use this data to decide the best way to cut back on energy usage.
On its website, measurable.energy emphasises that its hardware and software is designed to help individuals and businesses adjust their behaviour to use more renewable energy. The company writes that their solution, “pays back within two years and allows businesses to reduce electricity bills by at least 20 per cent.”
Nowadays, it seems like just about every appliance and device has smart capabilities. When used correctly, many of these can help people save energy and money. Some recent smart devices Springwise has spotted include a smart cooking pot that helps users save energy, and a self-powered smart pillow that monitors sleep.
Prince William has announced the five winning projects of this year’s Earthshot Prize, founded by the royal together with British wildlife presenter David Attenborough to find solutions to “repair our planet”.
The Earthshot Prize winners each received a £1 million grant to scale their projects, with each tackling a different topic from regenerating nature and fighting climate change to eliminating pollution – whether at sea, on land or in the air – based loosely on the United Nations’ sustainable development goals.
Seaweed packing Notpla is one of the winners of the 2022 Earthshot Prize
Among this year’s winning projects is Notpla – a plastic packaging alternative that is made from seaweed, making it not just biodegradable but also edible – and an affordable flat-pack greenhouse by Indian start-up Kheyti.
This so-called “greenhouse-in-a-box” can help small-scale farmers, whose harvests have been affected by climate change, to produce seven-times higher yields using 98 per cent less water, the company claims. At the same time, the modular structure is 90 per cent cheaper than a standard greenhouse, combining a simple shading cloth with a drip irrigation system and netting on all sides to ward off pests.
Also among the prize winners is Kheyti’s flat-pack greenhouse
Omani company 44.01 took home another of the competition’s top prizes for its development of a carbon storage system that takes excess carbon dioxide from the air and reportedly sequesters it “forever” by turning it into rocks.
This involves sourcing the atmospheric CO2 from direct air capture (DAC) companies such as Climeworks, dissolving it in water and injecting it into formations of a rock called peridotite, which is abundant in Oman.
Over the span of a year, the peridotite mineralises this carbon dioxide and turns it into solid rock in a natural process known as mineral carbonation, which normally takes thousands or even millions of years.
44.01’s carbon storage system makes use of peridotite
44.01 is among a growing cohort of companies developing technologies to accelerate this process, which is being billed as a solution for carbon storage that is stable and permanent, and thus does not require long-term monitoring.
“We have found a natural process that removes carbon and we’ve accelerated it,” explained founder Talal Hasan. “We believe this process is replicable globally and can play a key role in helping our planet to heal.”
Also among this year’s Earthshot Prize-winning projects is a stove developed by a women-run company in Kenya that runs on processed biomass instead of straight charcoal.
As a result, Mukuru Clean Stoves produce 70 per cent less air pollution than the traditional charcoal cookstoves currently used by around 700 million people across Africa.
The Queensland Indigenous Women Rangers Network received this year’s final accolade for its work in protecting Australia’s Great Barrier Reef by making use of “60,000 years of Indigenous knowledge” combined with modern, digital technologies such as drones.
Mukuru Clean Stoves run on processed biomass
The winning projects for the Earthshot Prize, which says it was “designed to find and grow the solutions that will repair our planet” were announced during a high-profile ceremony in Boston’s MGM Music Hall. This was broadcast by the BBC and presented by the Prince and Princess of Wales alongside celebrities including singer Ellie Goulding and footballer David Beckham.
“I believe that the Earthshot solutions you have seen this evening prove we can overcome our planet’s greatest challenges,” Prince William said. “And by supporting and scaling them we can change our future.”
“Alongside tonight’s winners and finalists, and those to be discovered over the years to come, it’s my hope the Earthshot legacy will continue to grow, helping our communities and our planet to thrive.”
The Queensland Indigenous Women Rangers Network was the final winning project
The ceremony received criticism from some viewers, as celebrity presenters and performers were flown into Boston to attend the event while the awards’ actual recipients accepted their awards virtually to save travel emissions.
Similarly, Beckham was called a “hypocrite” for his involvement in the event due to his ambassadorship of the Qatar World Cup, which has recently come under fire for its “disingenuous” carbon neutrality claims as the event looks to be on track to emit more CO2 than any other sporting event in recent history.
The Earthshot Prize was awarded for the first time ever last year, with winners including a restorative ecosystem scheme in Costa Rica and a tool that creates fuel from waste. The prize is set to run annually for the next eight years, during what has been dubbed the “decisive decade” for climate change action.
The Department of Energy released the residential segment of theU.S. Building Stock Characterization Study to give decisionmakers a science-based tool to identify technologies and solutions to drive the US housing stock toward zero carbon operation. The National Renewable Energy Laboratory, with input from the Advanced Building Construction Collaborative led by the Rocky Mountain Institute, developed the benchmark survey and accompanying dashboard. Typology studies like this have valued precedents in other countries, particularly in Europe, but this is the first-ever, national-level study of the US housing stock.
Updated in 2022 to include commercial buildings, the analysis segmented the US housing stock into 165 subgroups based on climate zone, wall structure, housing type, and year of construction. For each segment, thermal energy use (i.e., energy used for HVAC and water heating) was analyzed by end-use and segment. This gives policymakers and business owners insight to prioritize specific regions, housing segments, and target technologies for efficiency and electrification upgrades.
Primary high-level takeaways
Single-family detached homes
Not surprisingly, most residential thermal energy use is in single-family detached homes, which constitute the majority of residential buildings in the US. Single-family detached homes also have the highest thermal energy end-use per square foot (energy intensity); plus the largest square footage per home. This one-two punch means that any zero-carbon strategy must address this sector and its complex ownership structures, small individual building sizes, and diverse architectures.
Air leakage
Air leakage (infiltration) is the primary driver for heating loads in every climate region studied. For example, in multifamily buildings in cold climates, air leakage is nearly double all other envelope heat transfer component loads combined. This prioritizes insulation and other air-sealing strategies—especially those that limit disruptions for occupants during renovations. More research is needed on panelized walls, drill-and-fill insulation, and window retrofits to prove their effectiveness. Reducing air leakage, combined with mechanical ventilation, could also provide additional, non-monetary benefits for occupants, such as better thermal comfort, reduced moisture, and improved indoor air quality.
Mobile Homes
Mobile homes are extremely energy-intensive. Despite comprising a relatively small share of total housing units in most climate regions (around 4% to 9%), mobile homes typically have much larger thermal energy consumption per square foot than other building types. This inordinate energy intensity increases in older mobile homes in cold or mixed climate regions, where oil and gas heating are common; but is also problematic in hotter climates, where electric heating and cooling dominate.
Retrofitting mobile homes will likely offer an array of benefits for occupants, starting with reduced energy bills. Often, this might entail replacing the unit completely, although there could be significant barriers, such as local codes, taxes and ownership structures, as well as potential equity implications of displacing occupants.
Electrification
Fossil fuel–based space and water heating must be replaced to achieve decarbonization. These are the largest contributors to energy intensity and total loads. Again, electrification is needed across the US, in colder climates where oil and gas space and water heating are most common, and warmer regions with less reliance on fossil fuels. By benchmarking the different segments, the study informs decision-makers on where existing technologies are cost-effective, and where additional incentives or other cost reductions might be needed. (The DSIRE database is a great place to easily search and find a wide variety of state and federal financial incentives for sustainable new construction and renovations.) Some housing segments may also require envelope retrofits, to make electric heating pencil out, such as in the cold Northeast and Mid-Atlantic regions.
Solutions work across segments
The good news is that retrofit and building solutions are largely transferable among different residential segments. For example, energy efficiency packages developed for single-family detached, midcentury wood frame construction (which is the single-family segment with the highest thermal energy use in three of the five climate regions) will likely be applicable to other segments, such as other wood frame single-family detached vintages, as well as low-rise, wood frame multifamily buildings. Similarly, solutions developed for Marine-climate multifamily buildings, where water heating is the largest energy end use, could potentially apply broadly, as water heating retrofits aren’t impacted by the existing envelope.
Next steps to zero carbon
Local policymakers and building professionals should check out the free online dashboard that accompanies this report. Deep dive to explore building characteristics by specific state or county, examine nonthermal energy use, explore detailed HVAC configurations, and more. The online dashboard can serve as a baseline for the development of local efficiency and decarbonization strategies; and inform businesses on local opportunities. The commercial building recommendations and dashboard are also worth exploring.
In addition, this comprehensive, building characterization study will directly support technology and development goals nationwide, and further the work of the Advanced Building Construction Initiative as they explore avenues toward better performance and zero carbon. Beyond the major takeaways above, the ABC Analysis Working Group will identify additional home segments and strategies to prioritize for high decarbonization impact. And then model individual and packaged upgrades appropriate for particular segments.
Spotted: Increasingly, green hydrogen is touted as a crucial element in the world’s journey to carbon zero. UK startup and underground energy storage specialist, Gravitricity, is completing its design of purpose-built underground lined rock shafts which would enable efficient underground hydrogen storage.
Gravitricity believes its storage technology, which it calls FlexiStore, is a ‘Goldilocks’ solution to the obstacles facing hydrogen storage. Unlike above-ground hydrogen storage alternatives, FlexiStore provides a much bigger and more secure system. It is also more flexible than subterranean salt caverns – another commonly suggested method of underground storage.
One FlexiStore could store the green hydrogen generated by an offshore wind farm, but this would fill up daily and would need to be emptied regularly. To make the process more efficient, multiple stores could be constructed so that large amounts of wind energy that would otherwise go to waste could be soaked up. And unlike salt cavern storage, which naturally requires specific geological environments, Gravitricity’s stores can be built wherever they are needed.
Gravitricity has already identified many sites for its UK pilot project and is discussing the project and future commercial schemes with site owners. The company recently completed a £300,000 (around €341,000) feasibility study, which showed it is technically and commercially viable to store large amounts of compressed hydrogen with the Flexistore technology.
Springwise has spotted other innovations aimed at storing hydrogen. HydroSolid developed a way to store and transport large amounts of hydrogen at low pressures using a new nanomaterial, and EPRO found a way to transport green hydrogen in powder form.
