The Zero Carbon Renovation Revolution  

The Zero Carbon Renovation Revolution  

by  JP Barton

Over 75 million existing homes in the U.S. are dependent on fossil fuels for heating, hot water, and cooking. It is estimated that 70% of these will still be in use by 2050. Most of these homes were built over thirty years ago and are poorly air-sealed, inadequately insulated, and would benefit substantially from deep green energy renovations on the path to zero. In 2021 alone, according to the EPA, existing homes were responsible for emitting approximately 850 million metric tons of carbon into the atmosphere. 

If we achieve carbon neutrality, renovating these homes on the path to zero is a significant and urgent challenge. The U.S. market alone is projected to be as much as $3 trillion over the next decade—with a potential 50 million homes at an estimated cost of $60,000 per home – and has been largely overlooked until now. Hardly a dent has been put into this massive and untapped market, creating an opportunity for an important reduction in GHG emissions on a large scale as well as creating numerous opportunities for new businesses and millions of new jobs.

Free Enterprise is Taking on the Challenge

Now several ambitious startups are ready to take on the challenge of fixing these homes. One of the most promising is a Colorado-based climate-tech company called GeoSolar Technologies (GST). The company was formed in early 2020 by a team of leading climate scientists and engineers to find better and more efficient technology for heating, cooling, cooking, and powering homes with less carbon emissions, better health, and improved air quality (IAQ) for the occupants of the home. 

GeoSolar Technology’s Vision

The company’s mission from the start has been to make a meaningful contribution to climate change by lowering global temperatures through reducing greenhouse gas (GHG) emissions from existing and newly built homes while improving the health of residents and creating financial returns to the company’s shareholders. The company believes most of the 75 million US homes that use fossil fuels to heat and cook are prime candidates for economic conversion to zero carbon. Their turnkey, all-inclusive package of expert-vetted technologies and energy efficiency systems has the potential to disrupt the home energy market. It has already been successfully implemented in 28 new energy-efficient, all-electric homes in a fossil-free community called the GEOS Neighborhood in Colorado. These homes have no gas bills, minimal electricity bills, improved health, and low carbon emissions. There were zero Covid-19 cases in the neighborhood throughout the pandemic, a solid testament to the air purification system provided by these homes. GEOS has proven the viability of all-electric housing and provides residents significant health benefits from smart ventilation and zero emissions from gas burning.

The SmartGreen Home ™ 

Based on GEOS’s learned, GST has spent almost two years developing a whole home energy system called the SmartGreen Home™  that can be installed into new or existing homes and transform them into a zero-carbon, 100% clean electric home. It produces all the energy the homeowner needs and does so economically. The system also monitors the CO2/oxygen ratio and removes Covid and other microbes and viruses. The company has filed for U.S patent protection on the whole home innovative clean energy system. 

The GST SmartGreen Home ™ system is based on three essential elements: decarbonization, electrification, and home purification. It reduces energy needs by insulating and air sealing the home, upgrading windows and doors, using air to air or geothermal heat pumps for HVAC along with solar in concert with robust air management and monitoring, heat pump hot water, battery storage, electric appliances, electric vehicle charging, and a central AI software-controlled center operated by smartphone. You can learn more here about how the SmartGreen Home works.

The GST Business Plan

GST provides everything needed to make the complete upgrade from dependence on fossil fuels to 100% clean electric. The system can also integrate a new electric vehicle (EV) with bidirectional charging to power the home with the EV during power outages and make money for the homeowner by selling electricity back to the grid at peak demand rates. 

To bring this program to as many homeowners as possible, GST is partnering with successful solar installation companies across the country to become dealer/licensees and training them in the SmartGreen Home™ technologies and systems. These solar contractors are in touch with their local market and have an active sales force in place. They will offer a greatly expanded product line and provide the system sales, customer contact, and installation. At the same time, GST is developing a major national advertising/public relations campaign that will educate the public about the virtue of all-electric living and will provide licensees with additional leads, removing the expense of lead generation. GST is compensated with a 7.5% licensing fee on each sale/installation.

The SmartGreen Home technology starts with an energy audit and blower door test.

The gas furnace, water heater, gas stove, and other gas appliances are removed, eliminating gas lines and the harmful use of methane. To streamline this process, GST utilizes proprietary online software and technology for analyzing homes, providing estimates, and starting projects very quickly. 

Geothermal Heat Pumps

The SmartGreen Home™ system includes an option for the GST geothermal heat pump system. It can heat and cool the whole home while handling much of the load of a companion heat pump water heater. It is extremely valuable for the right homeowner and is especially suited to larger homes and for those who can afford the reliability and comfort of these highly efficient systems.

Marketing – The Key to the Zero Carbon Renovation Revolution

Once a homeowner understands the clear superiority of the all-electric home and that there is no compromise in comfort, they will be excellent candidates for purchasing a system. To that end, GST’s national advertising campaign to introduce the SmartGreen home will begin this spring with the key themes of Eco Luxurious and Healthy Homes – Healthy Planet.  Homeowners are particularly motivated to go all-electric when they understand the health benefits to their family and understand the basic concept that “Gas is choking the environment and choking your family.”  In addition, most homeowners are motivated by lowering their energy bills close to zero. While not all homes will get all the way to zero, the HERS ratings, which will vary from home to home, should be in the single digits,  with the goal of having no gas bill and minimal electricity bills.  With battery or EV energy storage, a homeowner could also be compensated by selling electricity back to the grid during peak demand.

Utilizing existing solar installers as licensed dealers for the sale and installation of the SmartGreen system, combined with its national advertising, marketing and lead generation plan, GST intends to provide a much broader public understanding of and interest in energy efficiency renovations. This aggressive marketing, along with GST having hundreds of licensees across the country installing thousands of SmartGreen Home Systems, will help accelerate the zero renovation revolution and establish the SmartGreen brand as the “Gold Standard” for the green all-electric home.

How GST Addresses the Resistance Factors

GST offers three tiers of SmartGreen Home renovation packages to homeowners catering to their specific needs and income levels: Silver, Gold, and Platinum priced at $40,000, $60,000, and $80,000 (after generous tax incentives). The most significant factor holding them back from renovating on the path to zero energy and zero carbon is the upfront costs for most homeowners. To address this, GST offers 100% financing at low rates, with monthly utility savings often covering the monthly payments. 

GST presents the SmartGreen Home system as a wise investment for the homeowner. A typical home will appraise $20 more per annual dollar saved by a more efficient energy system. SmartGreen Homes systems often save a homeowner between $2,000 and $6,000 in utility bills annually, so, at $20 per annual dollar saved, there is an increase of $40,000 to $120,000 respectively in the home appraisal. The actual appreciation is likely more than that. 

Another resistance factor to energy efficiency renovations is the disruption and inconvenience to the homeowner and their family while renovating. GST addresses this by aiming to complete the work within two to three weeks of issuing the permit and by allowing the homeowner to remain at home while the renovation is completed.

Driving the Zero Carbon Renovation Revolution

GST, along with other national startups, such as Sealed and Saaf, will help create the consumer demand needed to transform the existing housing stock into energy-efficient healthy homes through the power of marketing. The transition to all-electric homes is imminent, and GST has the opportunity to make an immense contribution to the battle against climate change – all the while fulfilling their fiduciary duty to shareholders with a highly profitable business model.  It aims to be a win for homeowners, a win for investors, and a win for the climate and the planet’s future well-being.

JP Barton is a long-time Colorado-based environmental activist investor and former investment banker. He advises companies, including GST and other ESG companies, on capital formation and growth strategies. He is a leading proponent of solar energy and an aggressive transition away from fossil fuel to a future of all zero-carbon 100% electric homes and electric vehicles.

Harnessing microbes to grow cement

Spotted: Cement has a huge carbon footprint – contributing up to 8 per cent of total global emissions. Much of this comes from the process of heating limestone to very high temperatures. This not only uses a tremendous amount of energy but also releases carbon dioxide directly. Now, startup Biomason has developed a way to ‘grow’ a cement substitute using micro-organisms.

The startup uses a process similar to how coral reefs and shells are formed, where organisms lay down layers of calcium carbonate. The company starts with recycled aggregate. This consists of the tiny bits of material that are held together by cement in concrete. Biomason then adds a strain of bacteria, along with the calcium, carbon and nutrients the bacteria needs to grow. As the micro-organisms grow, they produce calcium carbonate, which acts like a glue to secure the aggregate together.

The process operates at room temperate, reducing the need for heating. It also cures more rapidly than cement, and the end product is stronger than traditional concrete. The company is currently making small quantities of a tile called Biolith for industrial clients. Because the process can use existing concrete production facilities, it should be relatively cheap to scale up. Currently, several concrete producers are examining ways to incorporate Biolith production into their plants.

Biomason founder Ginger Krieg Dosier explains that the product does not need to be disruptive in order to make a big difference. “It didn’t make sense to disrupt everything in the entire concrete value chain. From day one, even before Biomason was named, it was very important for us to develop a technology that was easy to use, especially with existing concrete producers.”

Tackling the high environmental cost of concrete production is very high on the list of green researchers and entrepreneurs. Some of the other ideas we have seen at Springwise include solar-powered cement production and a bio-concrete made from weeds and shells.

A portable device rapidly detects toxins in crops

Spotted: Mycotoxins are poisonous substances produced by fungi. They can be found in food, with around 25 per cent of agricultural commodities affected each year. Cereals, nuts, spices, dried fruits, apples, and coffee beans are particularly susceptible. Not only does this pose a threat to human health – it also leads to food waste. And climate change is contributing to the challenge, with increasingly humid conditions leading to higher rates of mycotoxin contamination in food products and animal feed.

Due to the threat posed by mycotoxins, agricultural produce must be tested. But many traditional techniques require both skilled personnel and the use of a laboratory. This leads to a slow turnaround time of around seven days.

To tackle this, Kyiv-based startup BIOsens, has developed a portable solution for testing crops in the field. This consists of a device that can be used by untrained personnel outside of a lab setting. The device is unique in automating the preparation of crop samples and can analyse the mycotoxin content of crops within 21 minutes – allowing farming companies to make quick decisions on crop management. Information on the results is provided in an easy-to-access format via a mobile app.

The company stresses that the precision offered by lab tests is valuable, but that immediate results from field tests are more important for farmers who need to make decisions on the ground.

The startup was founded in 2018 and has spent the last three years developing and testing its technology. The company’s plans are for commercial sales to begin by the end of 2022.

Reducing food waste is crucial for curbing climate change.
Other innovations spotted by Springwise that tackle the issue include a food
preservative that modifies
the air around produce, and a digital
platform that connect food producers who have surplus or imperfect produce
with manufacturers who can use it.

5 Elements of a Winning Architectural Rendering

Send Us a Rendering. Tell Us a Story. Win $2,500! Architizer’s 3rd Annual One Rendering Challenge is open for entries, with a Regular Entry Deadline of March 11th, 2022Submit a rendering.

Creating architectural rendering involves more than modeling a building 3D and then polishing it. In the early days of digital architectural visualization, buildings were simply populated with human cutouts corresponding to different activities and scales. Now, with the advancement in image editing software, artists are exploring creative avenues to tell elaborate stories in a single frame.

May it be the tale of a neighborhood forgotten overtime or the experience of a person waiting for the last train on a cold night, our past One Rendering Challenge entries have shown is that anything we imagine can be portrayed in a variety of ways. With the deadline of this year’s challenge fast approaching, we have broken down the five essential characteristics of winning renderings. Using past finalists as a point of reference, this article breaks down the different techniques and components that made them stand apart from the rest.

“Electric Rain” by Vittorio Bonapace

1. Create a Story

Emotional impact goes a long way from creating an impactful architectural representation. Images that tell us not only about the design details but also about the experience of walking through the architecture are often ones you would take a few more minutes to gaze at. Additionally, creating a narrative arc helps establish the context around the building and also highlights its significance in daily life. This story can be told by establishing a scene with the addition of characters, dynamic elements, picking the right time of the day or adding markers that give an indication of the weather. A story can also make the architecture the hero without having it take center stage.

In Electric Rain, creator Vittorio Bonapace takes us on a walk through a rainy city street. His image captures the loneliness and the urgency of an individual walking alone on a cold night, trying to find a warm place. This is done by animating the character and using static objects that are movable in the background. On the other hand, it also gives an idea of how chaotic and energetic this street could be at another time in the day.

“The Vent” by dennis allain

2. Find the Perfect Color Balance

The tone of the colors used is very effective in communicating the time and place in an image. Oftentimes, images with predominantly warm tones can intuitively read as more historic or nostalgic, while more futuristic images tend to use cooler, icier tones. A successful render can lean in one direction but must also include contrasting hues to add more depth and dimension to the composition. This can be done by using a combination of cool and warm shades, dark and light tones, or muted and bright hues in varying degrees of opacity.

Dennis Allen does this very well in The Vent. The image uses a variety of reds to depict the older construction and juxtaposes this with the bluish water, newer construction elements and a bright white building that remains in focus despite not taking up a large part of the canvas. The image is a lot warmer in tone, like a sepia photograph, the color palette evokes nostalgic associations with the past. Yet, at the same time, masterful layers of grey tones, white highlights and subtle bursts of blue and purple bring the scene to life. The ivory structure in the middle also balances the darker elements in the composition.

“Time Traveling” by Tigran Hakobyan

3. Play With Materials and Textures

The nature of materials in a render often depends on the project but choosing the right texture map to represent it is key. Having multiple textures in an image makes it feel a lot more tactile, making the experience of the image is richer. Even flat surfaces should have textures that show varying degrees of the same color to make them appear realistic. Furthermore, the addition of transparent or reflective surfaces can also amplify the effect of the other textures used.

This technique is evident in Tigran Hakobyan’s Time Traveling. There is an amalgamation of the past and the present with the imposing glass structure perched on a historic building. The rendering of the metal frames holding the glass triangles, the concrete support, arched fenestrations and even the cobbled sidewalk each add to the overall image. And even though the chimneys and ships in the background are covered in a layer of mist, we can see that there are not just flat color blocks; their textural quality peeks through the fog and makes the image more believable.

4. Get the Lighting Right

Lighting is key not only in architecture but also in its representation. In architectural visualization, lighting can be added in the form of environmental light, out-of-frame spotlights, incandescent fixtures, fires, reflections or a combination of all. These are especially helpful in creating a specific mood or even adding pops of color in visualizations. That said, it is important to be careful of how these different light sources react with each other as well as the materials and geometry of the elements in an image.

Orchard Jenga – Start of the night shift by Duy Phan is a excellent example of effective lighting in a render. The creator has established the time of dusk by using soft pink clouds and a slowly deepening blue. The partially lit building also does a good job of conveying the hour. We can see this not only through the reflection on the main building but also subtly in the shorter building on the left. The artist has used the lights within the main building not only to illuminate the elements inside the structure but also those in the lower half of the composition. The dark objects below are also highlighted using different vehicles with distinct headlights and taillights. Each of these light sources has a unique tone and path to keep them from overwhelming the image.

“Zoom to the future” by Carlotta Cominetti

5. Focus On Details

Most of us have heard the phrase “God is in the details.” This is also true for renderings. Even if not visible immediately, paying keen attention to the finer details can make a huge impact on how the overall render is perceived. This includes fenestration details, material reflections, smaller fixtures, vegetation, imperfections in surfaces or even the actions and attire of humans used in these images. Every item used in a render must be intentional, have a purpose and contribute to a better understanding of the image.

There is no shortage of intricate details in Carlotta Cominetti’s Zoom to the Future. Starting with the backdrop, we can see that the artist rendered the main structure to perfection and added nuances that make it more realistic and dynamic. This includes peeling wall paint, abandoned flower pots, trash cans and detailed doors and windows. Each of these additions tells us about the lives of the people inhabiting this structure. Going a step further, they have also added details like photo frames, chandeliers, books and humans within these homes in the background. When we look at the main glass tube, they have taken great care in understanding how the backdrop will warp when seen through a curved glass and have rendered these parts accordingly. They have also aligned the central statue in the building with a key segment of the tube to highlight it further.

Supporting plant growth with captured CO2

Spotted: Carbon dioxide is a greenhouse gas harmful to our planet. But it is also a commodity. Plants use CO2 in photosynthesis, and increasing its concentration in a contained environment like a greenhouse increases crop yields, boosting profits. Commercial growers therefore purchase CO2 for use in climate-controlled systems. Currently, commercial CO2 is produced as a byproduct of burning natural gas for heating. The other main option is a system based on CO2 in liquified form.

Now, Kyiv-based Carbominer has developed a new carbon capturing module that produces agricultural CO2 in a new way – by capturing it from ambient air. This system is installed on-site at a grower’s facility so there is no need to transport or liquify the CO2. This saves both emissions and money. In fact, the company claims that the CO2 it sells is at least 35 per cent cheaper than prices in most developed markets.

Carbominer undertakes the installation of the capturing module itself, taking on the associated costs. The customer then purchases the CO2 of the company at a target price of €135 per ton of CO2 – the lowest currently on the market.

In addition to providing growers with a good deal, by removing CO2 from the air and feeding it to plants in the contained setting of a greenhouse, the company is helping to tackle the greenhouse effect in the world at large.

While Carbominer’s initial target market is agriculture, there are many further commercial uses for CO2, which the company may explore in the future – such as carbonated drinks, fire extinguishers, and enhanced oil and gas recovery. While some of these other uses involve the gas returning to the atmosphere, by reducing indirect emissions from transport and liquification, the Carbominer system will still lead to environmental benefits compared to other production methods.

Springwise has spotted several other carbon capture
innovations. One converts captured CO2 into
aviation fuel, while another stores
it in rocks.

Windmill House By Michał Kucharski + o4 architekci

Browse the Architizer Jobs Board and apply for architecture and design positions at some of the world’s best firms. Click here to sign up for our Jobs Newsletter.

Windmills, historically used to grind grain using wind power, are an archetypal image of Poland. Widely used up to the time of the industrial revolution, today windmill structures can be found abandoned because they no longer keep up with the industrialization of agricultural practices. As they decay, these remains await a new lease on life. In Lublin, Poland, an old and disused windmill has been reimagined as a modern dwelling for rural escapes.

Architects Michał Kucharski and Mateusz Piwowarski of o4architekci have really worked their magic, transforming a figuratively fascinating building — an old windmill structure with a rigid, spatially limiting vertical layout — into an intimate, welcoming home in which historical features coexist with a contemporary, attractive design language.

The project involved conservation of the existing volumes, reinvigorated with an innovative interior layout organized along a vertical development. The building, with a floor plan measuring 21 x 21 feet (6.5 x 6.5 m), has four above-ground levels — three floors and a mezzanine — and a newly created basement level that extends the living space.

The basement level includes a garage, a technical room, services and a large lounge for guests, with direct access to the garden. The first level houses the reading room and the kitchen with a terrace that expands the dining area outside, while the two upper levels contain  bedrooms with bathrooms; the mezzanine level contains a multifunctional workspace with a large window that projects the view of the surrounding landscape.  

Diagrams by Michał Kucharski/o4architekci Mateusz Piwowarski

Three main materials coexist in the project: reinforced concrete, wood and glass. Each one is used differently, as either new or reused elements, making it possible to meet the requirements of the new residential use while preserving the recoverable original construction elements.

The historic load-bearing structure has been completely replaced by a new structure of reinforced concrete pillars and slabs. The outer walls are made partly of reclaimed wood planks and partly of new planks subjected to a carbonization process, which accentuates the material’s durability and creates a tone that harmonizes with the vegetation.

The roof pitches, supported by wooden trusses, are covered with wooden shingles. Some of the historic wooden beams have been recovered in the outer walls, creating the effect of half-timbered walls inside. The contemporary imprint is given by the glass openings: the vertical ones in the upper parts of the building establish a dialogue with the tight rhythm of the planks on the façade, while the horizontal ones on the ground floor, basement and mezzanine allow constant visual interaction with the garden and farmland.

Some original construction elements, such as a historic mill wheel and a trestle, dismantled and placed on the ground floor, have been recovered to keep alive the rustic and authentic aura of the place. Again in line with the intention of enhancing the value of reused elements with their own history and experience, the garden fence was built using recycled railway sleepers as fence spans, thanks to a happy idea of the client.

A place to rediscover the charm of the past without giving up comfort and domestic warmth and where the words of the late nineteenth-century French writer Alphonse Daudet seem to resound out loud among the wheat fields:

“I feel so good in my mill! It’s just the corner I was looking for, a small, fragrant, warm corner, a thousand leagues away from the newspapers, the carriages, the fog” (Alphonse Daudet, “Letters from my mill”, 1870).

And so we like to imagine a stop in this truly enchanting, secluded and authentic corner of Poland.

What Kéré Architecture’s Renderings Reveal About the Firm’s Design Process

The 10th Annual A+Awards is still accepting entries! New this season, firms can gain recognition for their entire portfolio of work thanks to the addition of the new Best Firm categories celebrating practices of all sizes, geographies and specializations. Start your entry today.

Images tell powerful stories of people and place. For Kéré Architecture, renderings provide a way to showcase design and relate to larger contexts. Founded by Francis Kéré in 2005, with a dual focus on design and social commitment, the studio’s scope encompasses building, design and knowledge sharing. Known for its use of structure and materials, the practice’s portfolio spans a wide spectrum of projects from civic infrastructure to temporary installations, from concept to execution and across diverse geographies.

Kéré’s architectural reputation is strongly tied to the work’s built realization, and rarely is the process of a project’s creation explored through working images and visualizations. The following article examines a range of Kéré Architecture’s work through rendering, and it does so across different approaches and scales. A common thread emerges that is grounded in the renowned Burkinabè architect’s pioneering approach to sustainable modes of construction and context. The result is a portfolio that centers process and vision as the heart of design.

Inspired by the particularities of each project’s locality and its social tapestry, Kéré and his team work on projects across multiple continents. At the intersection of utopia and pragmatism, the team creates contemporary architecture that feeds the imagination with an Afrofuturist vision. Informed by tradition, the practice explores new modes of construction for which the foundations have long been laid.

Innovative uses of local resources and participatory design methods allow them to work beyond the boundaries of most established design practices and shed dominant norms. Exploring the many crossroads of the architectural realm and other disciplines, from art to technology, they expand their design practice through a deeper understanding of the relationship between rendering, illustration and built work.

Interior of Thomas Sankara Memorial. Render by Kéré Architecture

Interiors: Thomas Sankara Memorial

The Memorial Thomas Sankara is a project to honor and commemorate the memory of the seminal 20th-century Burkinabè thinker, former president and change-maker Thomas Sankara. The design proposal for the memorial reflects the genesis of revolution. The aim is the integration of a structure into an existing landscape that places innovation at its fore. In this rendering, the studio visualizes the interior of the memorial tower, an 285 feet (87 meters) high urban landmark for the Burkinabè capital, a design that stands on the site of the 1987 assassination of Sankara and his comrades.

Visitors are invited to climb the structure using a helicoidal ramp. The path is purposefully long and demanding, emulating the call not to fear the challenging road to change. Tackling the winding route is rewarded with stunning views across the city from a unique vantage point, which also features a restaurant shaped as the contour of Burkina Faso. A suspended funicular cabin provides access to the summit for older people and other abled. This rendering view is used to emphasize materials, light and circulation — all central elements of the design.

Xylem, Render by Kéré Architecture, photograph by Iwan Baan.

Early Concepts & Materials: Xylem

Kéré Architecture designed Xylem, the gathering pavilion for the Tippet Rise Art Centre, as a quiet, protective shelter. Named to evoke the vital internal layers of a tree’s living structure, Xylem is a place where visitors of this vast outdoor art space can gather to converse or sit and contemplate in solitude. Early renderings for the project show a much more playful and artistic interpretation of the finished design. Favoring illustration over realism, the renderings evoke layering that is much more conceptual than later renderings.

The logs of Xylem’s canopy are grouped in circular bundles within a modular hexagonal structure in weathering steel, supported by seven steel columns. The upper surface of the canopy is carved sinuously to blend into the surrounding hills. Simultaneously massive yet light, the roof is inspired by the tuguna, the sacred gathering space of many small Burkinabè communities. These low-level wood and straw shelters offer protection from the sun while allowing for ventilation.

Inside the pavilion, sunlight filters through the vertical logs, creating a soft play of light and shadow on the curvilinear seating and polished concrete circular platform below. The spatial complexity of the carved wooden seating elements encourages visitors to explore different views of the surrounding landscape.

Design Development & Scale: Xylem

Later in the design process you can see how Kéré Architecture’s renderings evolve to a more realistic approach. This brings in scale, sky and photo-realism as an entirely different approach to illustration. Located in a slightly sunken landform between the main facilities of the art center and the start of the hiking tracks, the pavilion nestles in a clearing surrounded by aspen trees, facing a small creek. Entirely carved in wooden logs, the pavilion invites visitors into the heart of the trees. The sustainable pinewood used for the entire pavilion, locally sourced from a natural pruning process that saves forests from parasitic bugs, is used in its raw state.

For Kéré Architecture, the definition of local resources has many layers, all of which are tightly interwoven. The studio believes that to build in a particular location means to engage actively with all aspects of the building practices of that place. Perhaps the most significant local resource is the existing built heritage, which teaches us how to adapt to our given context. In the work of Xylem and the render process, you can see how the studio strongly believes that a comprehensive understanding of local resources grounds each of their projects in its specific site and context.

Waterfront of the Niamey Nyala Masterplan. Render by Kéré Architecture.

Masterplans: Niamey Nyala Masterplan

Not only does Kéré Architecture work at the scale of architecture and pavilions, but also masterplans. The Niamey Nyala Masterplan puts forward a new vision, based on the premise of transforming the city by harnessing the hugely untapped potential of its riverbanks. The plan intends to create a network of public spaces along the Gounti Yéna (a tributary of the Niger River flowing through the city from south to north) and the Yantala Corniche on the left of the river, promoting Niamey’s biodiversity. The studio’s rendering for the masterplan combines an aerial view of the river and city superimposed with textures, architecture and infrastructure for the new project vision.

Along the Yantala Corniche, the existing tree nurseries and market gardens are reorganized to integrate recreational areas. In turn, the illustration shows how housing is planned along the riverside to slow the city’s expansion into the desert, as well as water transport to improve the connection between various points along the banks. The promenade planned along the Gounti Yéna waterway is combined with a series of waste stabilization ponds that filter the water through plants and sand. At the heart of the masterplan, a pedestrian bridge connects the two main promenades and spans the ring road, offering Niamey’s citizens a new vantage point over their city and its river.

Large-Scale Landmarks: TUM Tower

At the start of 2019, Kéré Architecture was commissioned to design a multi-use civic centre at the heart of the Technical University of Munich’s Garching research campus. Complementing the science facilities, this new central hub aims to promote cross-pollination between the public, faculty, alumni, students and researchers of various disciplines. The rendering especially showcases how each terrace is brought to life by the green façade, which serves as the building’s natural climatization system.

The design explores the organic and flexible possibilities of geometric forms, starting from the simple square. The TUM Tower includes a 360° view of the campus, made possible by the 22.5° rotation of a squared plan around its core axis. Acting as a landmark visible from afar, the TUM Tower brings the form of the campus’s functional architecture to new light. It playfully evokes both the essence and shape of the Bavarian maypole or Maibaum tradition – an annual celebration of communal gathering around a soaring tree-like structure.

Pavilions & Light: Serpentine Pavilion

Since 2000, the Serpentine Galleries annually commission an international architecture practice to design the Serpentine Pavilion in Kensington Gardens, London. In 2017, they chose Francis Kéré. Taking inspiration from the great tree in his hometown of Gando, under which members of the community meet to reflect on the day, Kéré’s design is based on creating this sense of community while connecting people with nature. A great overhanging roof canopy made of steel and a transparent skin covers the entire footprint of Kéré’s Serpentine Pavilion, allowing sunlight to enter the space while also protecting it from the rain.

Not only does this rendering showcase the materials and vision for natural light, but it also points to a larger approach to pavilion design. The project is defined by wooden shading elements that line the underside of the roof, creating a dynamic shadow effect that changes with the movement of the sun and clouds. The wall system is made of prefabricated wooden blocks assembled into triangular modules with slight apertures, giving a lightness and transparency to the building enclosure. The curved walls are split into four fragments, allowing four unique access points to Kéré’s Serpentine Pavilion. Completely detached from the roof canopy, these elements allow both the air and visitors to freely circulate.

Architecture & Facades: Benin National Assembly

Having outgrown its current building, which dates back to the colonial era of its past, the parliament of the Republic of Benin has entrusted Kéré Architecture to design a new national assembly that will embody the values of democracy and the cultural identity of its citizens. The project takes inspiration from the palaver tree, the age-old West African tradition of meeting under a tree to make consensual decisions in the interest of a community. Here, an approach to rendering not only accentuates the conceptual idea and brings it to life, but also tells a story of structure and the building façade.

The assembly hall is defined by the dynamic reach of the structure. The crown is comprised of offices and auxiliary functions, set back from the deep façade, which filters the sunlight. The trunk is hollow, creating a central courtyard that allows circulation spaces to be naturally ventilated and indirect light to penetrate the plan. A spiral staircase in its center connects the assembly hall on the ground floor to the offices above. In the southeast corner of the site, a public square marks the civic façade of the building, across from the former national assembly where Benin’s independence was historically declared.

Architects Can Bring the Outside In with Vitrocsa’s Stunning ‘Invisible Frame’

Erasing boundaries between inside and out has long been a preoccupation of architects around the globe, as countless clients seek open layouts and a sleek, modern aesthetic with minimal visual interruptions. However, truly seamless transitions are not easily achieved: The use of conventional glass walls with sub-par frames often result in uncomfortable interiors, energy inefficiency, and excessive hardware that contradicts that feeling of openness.

Now, this once-elusive goal can be achieved simply and easily thanks to Vitrocsa’s new single-track, insulated invisible frame. Able to accommodate extra-large glass panes with a fully concealed frame, the single-track insulated Vitrocsa invisible frame is a significant innovation in glass wall systems. New to the market in 2021, it picked up an array of honors in Architizer’s A+Product Awards categories for Residential, Doors & Hardware, and Commercial as well as finalist honors in 5 additional categories.

Operable glass walls have been around for a while, but Vitrocsa’s single-track invisible frame is a leap forward due to the level of insulation it can provide. With the option of double or triple glazing on a single track, designers can confidently specify the system knowing it will provide a comfortable environment in even the most extreme climates. Using Vitrocsa’s insulated frame allows for design of an operable glass wall in the mountains, beach, or city, all while ensuring that interiors are never too cold, too hot, or too loud.

Superior insulation also means superior energy efficiency. While glass walls can often be associated with excessive heating or cooling to make up for temperature differentials between inside and out, the level of insulation provided by Vitrocsa’s invisible frame ensures minimal heat loss or gain. This translates into lower levels of energy use needed to heat or cool an interior than typical glass wall systems require.

The key to this framing system’s top notch performance lies in its construction. The Vitrocsa system was developed by Eric Joray, an orchid-growing enthusiast who built numerous conservatoires after working in both watchmaking and the creation of prefabricated homes. This unusual combination of pursuits, each requiring an extraordinary attention to detail, eventually led him to become a windowmaker.

Joray’s unique mix of talents are evident in the refinement of each new iteration of Vitrocsa frames, culminating in the elegance and simplicity of the new single-track frame. With no need for an internal or external architectural enclosure, and featuring jambs less than three quarters of an inch thick, Vitrocsa’s roots in fine-tuned engineering are clearly apparent in this system.

The single-track innovation in Vitrocsa’s insulated, invisible frame greatly reduces the amount of hardware needed when specifying multiple panels to run on adjacent tracks, which allows the panels to be stacked together when the wall is open. This configuration maximizes both the view to the outside when the wall is closed, and the area of the wall that can be opened, greatly enhancing the sensation of an open-air building when it’s desired.

Achieving that sense of openness without compromising thermal and mechanical performance is where the Vitrocsa single-track frame excels the most. Able to accommodate glazed surfaces of almost 200 square feet, the new Vitrocsa frame allows architects to incorporate dramatic glass walls into their designs, offering wide, unimpeded views of the surrounding landscape. Thanks to the concealed frame, when an operable system is closed, the glass wall still appears virtually invisible.

Arguably the greatest effect of the new frame can be witnessed when Vitrocsa’s operable system is fully opened. Completely folding away one or more entire walls of a building to reveal the outside, without any noticeable transition, provides an uplifting experience that many architects desire to achieve with every project.

For many years, architects have sought to design buildings that eliminate the distinction between indoors and outdoors, constantly running up against the restrictions of temperature differences and obtrusive frames. With the innovative design of Vitrocsa’s single-track, insulated invisible frame, architects now have the possibility of fully realizing this creative goal.

How Universal Design Can Drive Inclusivity

Celebrate a decade of inspirational design with us! The 10th Annual A+Awards is officially underway, and the Extended Entry Deadline is March 4, 2022Click here to start your entry today.

Despite all the talks around inclusivity and diversity in all aspects of life, the idea of universal design is still not one that is widespread. The term, first coined by American architect Ronald Mace, and then later popularized by architect Selwyn Goldsmith, explores a branch of design that caters to everyone regardless of their age and abilities. This implies going beyond wheelchair-accessible spaces and addressing the vast spectrum of disabilities that can exist.

The limitations of designed environments first became a topic of discussion after the second World War when we saw a large number of injured veterans. While the advancement in medicine made it possible for them to live longer lives, there wasn’t enough infrastructure that was entirely accessible to them. Veterans in the United States demanded equal rights for themselves, leading to the establishment of the Americans with Disabilities Act in 1990.

But having equal rights was not enough. When it came to spaces and environments, Mace was instrumental in creating the seven principles of Universal Design in 1997. These are equitable use, flexibility in use, simple and innovative use, perceptible information, tolerance for error, low physical effort and size and space for approach. They are meant to serve as guidelines for designers to create more inclusive and accessible environments.

Equitable use implies the provision of the same degree of access, security and safety for all users. The principles also point to flexibility by accommodating a wide range of preferences such as left and right-handed access, provision for different paces of movement and so on. They also state that the design should be intuitive in a way that individuals with different literacy and language skills should be able to navigate the space without any difficulties. The information provided should also be presented in graphic, audible and tactile forms. Each space must have warnings of hazards and errors and preferably have these high-risk elements isolated. Transparency in buildings, recurring seating spaces, anti-skid surfaces, tactile floor guides and handrails with easy grips are just a few other examples of elements that can be included.

According to Indian architect and Universal Design advocate Kavita Murugkar, Universal Design is an almost fundamental value given that it ties in with accessibility and, in turn, an individual’s right to freedom. She said, “Everyone is talking about equality and extending equal rights and opportunities for all individuals, and creating equal possibilities of participation in the society. This is possible only through equal means of access.”

While we have come a long way in our understanding of what design needs to do, there is still a slightly limited perspective of disability while designing. The needs of someone who is an amputee might be very different from someone who is visually impaired. The latter might need many more tactile and audible cues to guide them in spaces whereas an amputee could require some more room to accommodate any aids they might have.

Furthermore, someone with missing arms could require alternative ways to use buttons or even open doors. An individual with Parkinson’s might need spaces that have finishes and interventions that are favorable for those who struggle with balance. And that is just on the physical level. People with autism might require quiet rooms and those with dementia could benefit from surroundings that have fewer identical elements.

A project that has tried to address this is the Enabling Village in Singapore. Designed by WOHA, the community space offers retail, recreational and training services for differently abled individuals. All public spaces and restrooms in the building are wheelchair accessible. The event spaces have induction loops that can transmit audio to people using hearing aids with T-coils and they also provide braille maps of the space if needed. Even elements like ATM machines in the center have braille labels and earphone ports. The project includes a center for innovators to gather and test ideas for assistive technology. It is equipped with a room where these inventors can also test their products in fully soundproof and lightproof spaces. Furthermore, they are also creating job opportunities for the differently abled members of the community.

Another example of inclusive design is the Friendship Park in Montevideo, Uruguay that is designed by Marcelo Roux, Gaston Cuna, Patricia Roland and Federico Lezama. It is made in a way that children of all ages can enjoy the space regardless of their physical or cognitive abilities. Apart from the easily accessible spatial arrangement, materials like concrete, metal and rubber are used in abundance to provide tactile and aromatic cues to the users. The team has tried to incorporate more curved surfaces to avoid sharp edges; they have also used a variety of colors throughout to make it appear more fun and the spaces easy to recognize and remember.

Murugkar said the awareness about Universal Design is still not as much as it should be, especially considering its importance. She introduced it as an elective in Dr. B. N. College of Architecture in Pune, where she is an Associate Professor. But she believes that we need to get to a point where the subject is integrated into the entire curriculum and not just taught as a specialization. “Universal Design is a utopian idea. You can definitely not have a design that addresses the needs of every single individual on this earth,” she said. “It just aims to make the spectrum of usability of a particular service or product or an environment broader and broader.”

Inclusive design is more of a way of approach than a design methodology that must be implemented right from the conceptual stage and carried through to the smallest element in the final product. While this approach may give rise to innovation, the question remains: is actually possible to cater to every individual and make this philosophy a reality?
