On Saturday night, the awards were announced in the 2014 Solar Decathlon Europe, which is currently ongoing in the grounds of the Versailles Palace in France. The competition challenges university teams to build and run a full scale solar powered house, with awards being judged on a range of requirements including sustainability factors, architecture and comfort, with a different jury of three experts judging each requirement.

The overall winner, based on a combination of all the factors, was “Rhome for Dencity”, by the team from Roma Tre University, with a proposal that seeks to ”re-densify and re-qualify the boundaries of Rome” by applying principles of density and sustainability to this area where ”, country, archaeology and illegal buildings are interwoven.”

Why 3D Printing Is Not As Sustainable As Its Defenders Say

 is a column, penned by Christopher Brenny and presented by ArchDaily Materials, which investigates the innovative applications of  in architecture.

On a purely aesthetic level, 3D printing holds great potential for buildings – all the possibilities of sculpted concrete without the bulky and expensive formwork. Taken to an extreme, it could someday make Hadid-like forms so cheap to execute that they become mundane (even for a non-architect) – maybe even causing the profession to re-evaluate what qualifies as high design. 

However, the more important advantage of 3D printing, what could spur its acceptance as a viable means of , is its supposed . Among its oft-cited advantages are a use of “green” materials and a reduction in construction waste. However, is 3D Printing really as sustainable as its defenders contend?  

Tree-Like Skyscraper Takes Urban Farming to Next Level

Urban farming is nothing new, but Aprilli Design Studio‘s proposal for a completely open-air skyscraper does put a novel spin on the sustainable ideal. Instead of tacking greenery onto roofs and balconies, they incorporate agriculture into cities by dedicating entire buildings to the cause.

Material Minds, presented by ArchDaily Materials, is our new series of short interviews with architects, designers, scientists, and others who use architectural materials in innovative ways. Enjoy!

Wood. The United States is the largest producer of the natural resource in the world. But yet we rarely see it in commercial, high-rise construction. So we asked a wood expert – Rebecca Holt at Perkins+Will, an analyst for reThink Wood‘s recent Tall Wood Survey  – to tell us about its potential benefits.

AD: Why is wood a material architects should use in taller buildings?

There are lots of reasons to consider wood – first it has a lower environmental impact than other traditional choices like concrete and steel.  Wood is the only major building material that is made the by sun and is completely renewable.

Inside Masdar City

The Middle East has historically been known for many things — sustainability not being one of them. The clash of Western values with the harshness of the local climate can often wedge sustainability between a lot of sand and a hard place. Though there is a broad critique of the unsustainable attributes of the region’s development path, for years there has been a shining exception: Masdar City in the United Arab Emirates, seventeen kilometers east-south-east from the city of Abu Dhabi.

Masdar City exists as an project run by the renewable energy company Masdar, who has committed $15 billion to making Masdar City the planet’s most sustainable new city. Unlike Abu Dhabi, a city which unthinkingly follows antiquated models and Western building principles, Masdar City has a wealth of potential to offer the world of green urban planning – something the world sorely needs.

But Masdar City is certainly not without its share of critics. On first approach, the concentrated development, located in the center of six square kilometers of empty space, does little to awe, especially in comparison to the sprawling wave that is Abu Dhabi. Thanks largely to the global financial recession, buildings currently comprise less than 10% of the area committed to the urban experiment. Even today there is a group of onlookers that suggest Masdar City may just be a mirage after all.

However, this broader view is not necessarily synonymous with the bigger picture.

The Pre-Fabricated Skyscraper & The Clean-Tech Utopia: Two Game-Changing, Sustainable Proposals in China

How can the city be reinvented to save the world? Chinese business magnate Zhang Yue and Finnish professor Eero Paloheimo are two men with very contrasting answers to this loaded question. Zhang Yue’s answer puts trust in pre-fabricated, high-density vertical development, whereas Paloheimo envisions a built-from-scratch, clean-tech sprawling utopia. Their grand ideas, met with both skepticism and excitement, are documented in a new film by Anna-Karin Grönroos. To watch the trailer and learn more about the bold proposals, continue after the break.

Have you ever wondered if you would be happier working in a LEED building? Wonder no more – a new study says no. Although the findings indicate employees are generally satisfied with working in green-certified buildings, they are no happier than they would be in a non-LEED building. The study, which contradicts previous findings, was conducted by Sergio Altomonte from the Department for Architecture and Built Environment at the University of Nottingham and Stefano Schiavon from the Center for the Built Environment at the University of California Berkeley. 

To arrive at this conclusion, data was collected through a web-based survey tool by the Center for the Built Environment (CBE) at the University of California Berkeley. In total, 65 LEED and 79 non-LEED buildings were selected to participate in the study. Building occupants were surveyed and asked to rate their satisfaction on a 7-point scale of 17 indoor environmental quality parameters, including amount of light, furniture adjustability, air quality, temperature, and sound privacy.

The Steel Age Is Over. Has The Next Age Begun?

As of now, carbon fiber has only been applied to small scale applications, such as the Textile Room by P-A-T-T-E-R-N-S. Image © Monica Nouwens

Andrew Carnegie once said, “Aim for the highest.” He followed his own advice. The powerful 19th century steel magnate had the foresight to build a bridge spanning the Mississippi river, a total of 6442 feet. In 1874, the primary structural material was iron — steel was the new kid on the block. People were wary of steel, scared of it even. It was an unproven alloy.

Nevertheless, after the completion of Eads Bridge in St. Louis, Andrew Carnegie generated a publicity stunt to prove steel was in fact a viable building material. A popular superstition of the day stated that an elephant would not cross an unstable bridge. On opening day, a confident Carnegie, the people of St. Louis and a four-ton elephant proceeded to cross the bridge. The elephant was met on the other side with pompous fanfare. What ensued was the greatest vertical building boom in American history, with Chicago and New York pioneering the cause. That’s right people; you can thank an adrenaline-junkie elephant for changing American opinion on the safety of steel .

So if steel replaced iron – as iron replaced bronze and bronze, copper –  what will replace steel? Carbon Fiber.
