Architectural design is crucial in the construction industry for several reasons:
Functionality: Architectural design ensures that the building or structure is designed to serve its intended purpose effectively. It takes into account the needs and requirements of the users, incorporating various functional aspects such as spatial planning, circulation, and accessibility. A well-designed building enhances productivity, efficiency, and overall user experience.
Aesthetics: Architectural design adds visual appeal and beauty to a structure. It considers elements such as proportion, scale, balance, materials, colors, and textures to create a harmonious and visually pleasing environment. Aesthetically pleasing buildings not only enhance the quality of life for occupants but also contribute to the overall urban or rural landscape.
Safety and Structural Integrity: Architectural design plays a crucial role in ensuring the safety and structural integrity of a building. It takes into account factors such as load-bearing capacity, structural systems, resistance to natural forces (e.g., earthquakes, wind), fire safety, and adherence to building codes and regulations. Proper architectural design minimizes the risks associated with structural failures, accidents, and disasters.
Sustainability: With growing concerns about environmental impact and resource conservation, architectural design plays a vital role in promoting sustainability in the construction industry. Designers consider strategies for energy efficiency, water conservation, use of eco-friendly materials, waste reduction, and integration of renewable energy systems. Sustainable architectural design minimizes the ecological footprint of a building and contributes to a greener future.
Economic Considerations: Architectural design influences the economic aspects of a construction project. Effective design can optimize the use of space, reduce construction costs, and improve operational efficiency. It takes into account factors such as lifecycle costs, maintenance requirements, and adaptability to future needs. Well-designed buildings have the potential to increase property value and attract occupants, contributing to long-term economic viability.
Cultural and Social Context: Architectural design is influenced by the cultural and social context in which it is situated. It takes into account local traditions, cultural values, and community needs. Architecture can reflect and reinforce cultural identity, provide spaces for social interaction, and contribute to the overall well-being of communities.
In summary, architectural design is essential in the construction industry because it ensures functionality, aesthetics, safety, sustainability, economic viability, and cultural relevance in the built environment. It integrates various considerations to create well-designed and meaningful spaces that positively impact individuals, communities, and the environment.
Contractors must keep up with technological advances to drive the industry forward, says Autodesk senior vice chairman Jim Lynch.
Globally, the built environment footprint is expected to double in size by 2060. For that to happen in line with net zero targets, technology is going to be critical to improving the way construction is carried out.
Jim Lynch, Vice President & General Manager, Autodesk Construction Solutions.
Autodesk senior vice chairman Jim Lynch puts it simply: “The industry has to find a better way to build and digital is going to play – and is already playing – a huge role in that.”
For technology to advance our construction techniques, digital literacy is going to be required in all practices and, ideally, through all phases of construction.
“The bare minimum is that contractors use digital technology on the job site for collaboration,” says Lynch.
“Ideally, they should use digital technology during the pre-construction process. Moving on from there they should use it to drive operations and maintenance, then take that project information from design out to a digital twin, where they can use that technology to provide management capabilities for the owner.”
To make this a reality, technology must be easy to deploy and adopt, according to Lynch. “If using and deploying technology is going to need weeks of training where you’re taking workers off the job, that’s not going to work,” he explains.
However, Lynch believes the onus is on contractors to invest more in improving their digital literacy if they are falling behind.
“You have to build up that digital muscle,” he says. “And I think, by and large, contractors really do understand that they have to take those first steps around collaboration, then extend those steps into using more digital during the planning process and then continue on from there.”
He believes that today’s contractors are embracing technology faster than ever, not only because of the competition, but also because of the expectations of clients and the government. He points to the UK’s Building Safety Act, which became law in April 2022, as a driver.
“That is really all about data; it is ensuring that owners, contractors and designers all play a role in making sure that digital information is created, captured and stored throughout the entire process.”
Lynch believes a big challenge is going to be attracting the workforce to build all the future projects – but that digital could play a part in drawing people in. “I think the use of digital technologies to drive better outcomes in construction will be intriguing to the younger generation,” he says.
“How to apply technology to the construction process, especially when you think about augmented reality and virtual reality applications, will drive a greater interest in the workforce.”
He adds that the industry has made great progress in its use of technology in recent decades. “But I think we’ve only scratched the surface,” he says. “I think the best is really yet to come.”

Designed to Adapt: Living materials are the future of sustainable building

By David Pacchioli
Working together across disciplines, researchers from Penn State and the University of Freiburg are applying materials that adapt, respond to the environment, self-power, and regenerate to meet the challenges of adaptive architecture.
The coming decades present a host of challenges for our built environments: a rising global population combined with increasing urbanization; crumbling infrastructure and dwindling resources to rebuild it; and the growing pressures of a changing climate, to name a few.
To become more livable for more people, cities themselves will need to become smarter, with buildings, bridges and infrastructure that are no longer static but dynamic, able to adapt and respond to what’s going on around them. If not exactly alive, these structures will need to be life-like, in important ways. And for that, they’ll need to incorporate living materials.

“Engineers and scientists have worked for hundreds of years with so-called smart materials,” says Zoubeida Ounaies. “Piezoelectricity was discovered in the 1880s.” Smart materials can sense and respond to their environment, she explains, “but they always need an external control system or source of power. Living materials that adapt, respond to the environment, self-power, and regenerate—in the way that materials in nature do—are the next logical step.”
A new paradigm: Engineered materials inspired by nature
Living materials, Ounaies explains, are engineered materials that are inspired by nature. Sometimes they even incorporate biological elements. Their dynamic properties, at any rate, enable them to adapt to changes in their environment, responding to external stimuli. They may change shape, heal themselves, even make simple decisions.
Ounaies’s counterpart at Freiburg is Jurgen Ruhe, director of the Cluster of Excellence in Living, Adaptive and Energy-autonomous Materials Systems (livMatS). At a webinar last summer Ruhe put it this way: “If we look at the materials of today, one of the very key features is that materials have properties which do not vary in time. But if we turn our view to nature, nothing is really constant. For living systems, adaptivity is the key to survival. The goal of our livMatS cluster is to generate materials systems which can adapt to changes in the environment based on sensory input and then improve over their lifetime.”
Importantly, Ounaies says, living materials are multifunctional. They don’t just provide strength or elasticity or hardness, they reduce environmental impacts and promote health; they monitor their own status, and when used up they can be recycled or reabsorbed. They harvest energy from their surroundings, store it, and use it for what they need. They do these things, ideally, while self-powering and without external sensors or motors.
Above all, perhaps, engineered living materials aim to be sustainable. “The concept requires us to look at the whole life cycle,” Ounaies says. “To think about the starting material, the extraction and manufacturing processes, the waste generated, the energy required.” The design must account for all. Thus, unlike many smart materials, living materials don’t put a harmful load on the environment.

“If you think about it,” she says, “adaptive behaviors happen in nature all the time. Maybe not in a material form, but certainly in systems. There are plant systems that do this. There are animals that do this. ” Nature does the original design work. “For example, if one investigates the hierarchical pattern of a mollusk shell or the intricate structure of bird wings, one is inspired to apply them to human made structures in ways that integrate multiple functionalities.”
Thomas Speck has been fascinated by biomimetics for 30 years. Trained as a biophysicist, Speck is now professor of botany at the University of Freiburg. He studies the functional morphology of plants—the relationship between structure and function—and how these “biological role models” might be applied to the world of technology. As director of the University’s Botanic Garden, he has over 6,000 species from which to find his inspiration.
Plants, says Speck, have important lessons to offer. “First, they are mobile, although their movement is often hidden from us,” he explains. “A lot of plant movements are very aesthetic—think of a flower opening. We want to transport this aesthetics into our architectural solutions.”

What’s more, Speck says, plants work their magic with a very limited number of structural materials. “Cellulose, hemi-cellulose, lignin, a bit of pectin. Three polysaccharides and one complex polyaromatic polymer. With these materials, which are all relatively easy to recycle, they are able to make fantastic structures, fantastic systems which work incredibly well.”
A simple example is the pine cone, whose paddle-shaped scales open and close in response to changes in environmental humidity. At the Botanic Garden, Speck and his colleagues have analyzed fossilized pinecones 50 million years old and found that they still perform like modern specimens. “And it costs no energy, because humidity changes are brought by sunlight,” he says.
As amazingly robust as the natural mechanism is, the pinecone is merely reactive, Speck notes. “If it’s wet, it’s closed. If it’s dry, it’s open.” In adapting this principle, he says, “We want to design systems that are interactive, that can combine movements, that make decisions. Biomimetics for us means we get inspiration from nature and then reinvent nature. We don’t copy it. We want to combine the best of both worlds: living nature and technics.”
In most of the MENA and the Gulf region, we reach for the A/C control when entering any living or working space. But as we casually flip a switch, we tend not to consider all those carbon emissions caused by machines.
After years of indulgence and as witnessed by all of the end results, climate change is forcing all to go green by trying to keep buildings cool as it gets hotter. Greening the Global Construction Industry has already engaged in developing new techniques, tools, products and technologies – such as heat pumps, better windows, more vital insulation, energy-efficient appliances, renewable energy and more imaginative design – has enabled emissions to stabilize the past few years.
The Conversation Weekly podcast is now back after a short break. Every Thursday, we explore the fascinating discoveries researchers are using to make sense of the world and the big questions they’re still trying to answer.
In this episode we find out how “modern” styles of architecture using concrete and glass have often usurped local building techniques better suited to parts of the world with hotter climates. Now some architects are resurrecting traditional techniques to help keep buildings cool.
From western Europe to China, North Africa and the US, severe heatwaves brought drought, fire and death to the summer of 2022. The heatwaves also raised serious questions about the ability of existing infrastructure to cope with extreme heat, which is projected to become more common due to climate change.
Yet, for thousands of years, people living in parts of the world used to high temperatures have deployed traditional passive cooling techniques in the way they designed their buildings. In Nigeria, for example, people have long used biomimicry to copy the style of local flora and fauna as they design their homes, according to Anthony Ogbuokiri, a senior lecturer in architectural design at Nottingham Trent University in the UK.
But in the 20th century, cities even in very hot climates began following an international template for building design that meant cities around the world, regardless of where they were, often had similar looking skylines. Ogbuokiri calls this “duplitecture”, and says it “ramped up the cooling load” due to an in-built reliance on air conditioners.
Alongside this, there was a massive boom in the use of concrete, particularly after the second world war when the Soviet Union and the US started gifting their cold war allies concrete technology. “It was a competition both to discover who actually mastered concrete and who was better at gathering the materials, the people and the energy to make concrete,” explains Vyta Pivo, assistant professor of architecture at the University of Michigan in the US. But too much concrete can contribute to the phenomenon of urban heat islands, where heat is concentrated in cities. Concrete is also a considerable contributor to global carbon emissions.
Some architects and researchers are working to rehabilitate and improve traditional passive techniques that help keep buildings cool without using energy. Susan Abed Hassan, a professor of architectural engineering at Al-Nahrain University in Baghdad, Iraq, focuses a lot on windcatchers in her work, a type of chimney which funnels air through houses to keep them cooler in hot climates. She’s now looking at how to combining underground water pipes with windcatchers to enhance their cooling effects.
Listen to the full episode to find out about other techniques being used to keep buildings cool without relying on air conditioning.

ArchDaily querying What Role Should Architectural Prototypes Play in the Global South produced the following, a commendable post from all points of view.
What Role Should Architectural Prototypes Play in the Global South?
It’s an essential component of the design process, where spatial ideations are translated into built form – the design of the prototype. Architectural projects, throughout history and in contemporary practice, have been prototyped to carry out both technical and aesthetic tests, where further insight is gained into the integrity of the design. It’s the blurred line between the experimental and the practical.
Antoni Gaudí’s 1:25 and 1:10 scale plaster models of Sagrada Família can be defined as architectural prototypes, and so can the wooden model of Filippo Brunelleschi’s Florence Cathedral dome. But these are investigations conducted on a smaller scale. It can be argued that architectural prototypes are most effective when built out 1:1, from which further architectural interventions based on the prototype have the security of a design attempt that is not a scaled-down version of the finished product.
But the making of these prototypes is a protracted endeavor – necessitating the complex maneuvering of resources, labor, and capital – for a structure that aims to merely lay the foundations for how similar designs should be approached in the future.
When scrutinized from the perspective of the Global South, this dialogue is complicated further – in countries that have been historically over-exploited and are currently under-resourced, are full-scale architectural prototypes wasteful if they don’t immediately function as a working building? Is it right for these prototypes to simply exist as say, explorations of new materials without serving as a structure that will be in constant use from its inception?
In colonial Africa, architectural experimentation was commonplace, from Fry and Drew in West Africa to Guido Ferrazza in Libya. This experimentation included that of French industrial designer and architect Jean Prouvé, who in 1949 developed Maison Tropicales – prefabricated, modular housing prototypes constructed out of aluminum designed to be easily transported, assembled, and disassembled.
The design problem that the Maison Tropicales had to solve was climatic – as France’s African colonies faced a shortage of housing and civic buildings. The prototype was designed for the equatorial climate, including a veranda with an adjustable aluminum sun-screen. Internally, walls were made of a combination of sliding and fixed metal panels – as glass portholes provided protection against UV rays.
But despite this resourceful, ingenious response to the tropical climate, the Maison Tropicale as a prototype failed. It was no less expensive than locally constructed buildings, and the French colonial bureaucrats did not warm to the industrial appearance of the house. The prototype, ultimately, was a colonial project built for French administrators. A prototype built for the colonial class that proved unpopular with them, and that instead of being widely adopted, was resigned to be a traveling object, making frequent appearances in design exhibitions. This prototype of the African Tropics became a design object that to most, was known outside of its intended context.
But contemporary practice in the Global South has offered up more substantial prototypes, where investigations into materials are coupled with substantial usage. Senegalese firm Worofila’s Ecopavillon in Diamniadio, constructed in 2019, is one such example. Commissioned by the Ministry of the Environment of Senegal, it is built with earth and typha – a type of water reed found in the Senegal River. Woven typha panels provide sound insulation, and when mixed with adobe bricks, provide thermal insulation.

As the prototype is part of the Senegalese government’s initiative to build a new city to ease congestion in Dakar, its usage is still in its early stages. The intention, though, is clear. The Ecopavillon will allow the monitoring of how the building’s materials behave, and performance can be assessed. the behavior of materials and to measure the performance of buildings. Furthermore, it can act as a training venue for craftspeople, where local knowledge of energy-efficient materials can be further developed.

The most tangible example of a living prototype in the Global South, however, is arguably found in Bangladesh, in Marina Tabassum Architects’Khudi Bari. It is a modular mobile housing unit, with an area of 128 square feet. Its light footprint and elevated form mimic the architectural vernacular of the Bengal delta, but more pressingly, it responds to climate change.
In an area with high instances of flash flooding, the raised second level acts as shelter for occupants as they await the receding of the water. In the Chars of Bangladesh – low-lying islands naturally formed by silt from rivers – the spaceframe structure is a crucial response, low cost, durable, and easily assembled and disassembled with minimum labor.
The true success of the Khudi Bari project can only be measured by what happens after the housing modules are built. A pilot project initiated by a non-profit organization affiliated with Marina Tabassum Architects in conjunction with private and governmental donors aims to establish at least 80 to 100 “Khudi Bari” modules in the flood-prone communities of Bangladesh by May 2023.
More crucially, March 2021 saw the first three homes built in collaboration with families, with some adapting their modules, with the vision for the future being that people involved in this pilot project will then become part of the training collective as the modules are initiated in other areas.
Perhaps this is how architectural prototypes built in the Global South should function – as bold, inventive assemblages, that are not only for observation and display, but instead examples of architecture that is dynamic, in use, and living.
Generations of travelers have stood before the “ksars” of Djado, wandering their crenellated walls, watchtowers, secretive passages and wells, all of them testifying to a skilled but unknown hand.
