New Research Proves that Iron Was an Important Medieval Building Material

The Gothic cathedrals of the middle ages have long been respected as sites of significant architectural and structural experimentation. Hoping to reach ever closer to God, the master masons of the period took increasingly daring structural risks, resulting in some remarkably durably buildings that are not only timeless spaces for worship but miraculous feats of engineering. However, according to new research by a team of French archaeologists and scientists, we still haven't been giving these historic builders enough credit.

How Simple Earth Blocks Could Revolutionize Construction for the African Island of Pemba

Pemba, a small Tanzanian island off of Africa's Eastern coast, is undergoing something of a construction boom. With half of the population aged under 30 and a culture in which a man must build a house before he can get married, a wave of new informal housing is sweeping the island. Historically, construction methods used by the islanders have been problematic: traditional wattle & daub construction typically survives for just 5-7 years; its replacement, bricks made of coral, not only require large amounts of energy to extract but have a devastating effect on the environment; and modern cement bricks most be imported at high costs.

Recycling In Practice: Perkins + Will Finds New Life for Cardboard Tubes

In architectural offices, the cardboard tubes used in large-format rolls of paper seem to multiply at an alarming rate, populating every nook and cranny until they fill the rafters. The team at Perkins + Will Boston have invented a cheeky solution to stem cardboard tube proliferation in the form of a privacy screen that behaves simultaneously as a sound and visual barrier, and as a storage space. Composed of dozens of reclaimed cardboard tubes fitted into a CAD-mapped and cut plywood frame, the 'wall' provides ample opportunities for drawing storage, sunlight mitigation, and playful interaction without disrupting workflow.

How Cutting Edge Technology Helped Recreate the Stella Tower's Concrete Crown

In some projects, preservation isn't just about retaining what's there, but also about putting back an element that has been forgotten to history (not always, though). This was the case at the Stella Tower in Manhattan, where as part of the building's recently completed condo conversion, JDS Development Group and Property Markets Group, along with architects CetraRuddy have reinstated the dramatic Art Deco crown of Ralph Walker's 1927 design.

Cristina Parreño Investigates the Tectonics of Transparency With Glass Wall Prototype

Architect and MIT Lecturer Cristina Parreño has created this new prototype for a self-supporting glass facade, entitled "The Wall." The design is the first in Parreño's "Tectonics of Transparency," a series of planned prototypes that will "explore the relationship between formal design, spatial perception, structural efficiency and systems of fabrication."

Emerging Objects Invents Earthquake-Proof 3D Printed Column

A team of California-based designers have invented an earthquake-proof column built of 3D printed sand, assembled without bricks and mortar to withstand the harshest seismic activity. The 'Quake Column' is comprised of a pre-determined formation of stackable hollow bricks which combine to create a twisting structure, optimized for intense vibrations in zones of earthquake activity. Created by design firm Emerging Objects, the column's sand-based composition is one of many in a series of experimental structures devised by the team using new materials for 3D Printing, including salt, nylon, and chocolate. The column can be easily assembled and disassembled for use in temporary and permanent structures, and was designed purposefully with a simple assembly procedure for novice builders.

Oak Ridge National Laboratory Develops 3D Printing Process at the Mircoscale

3D printing technology continues to advance, developing new applications which are particularly promising for the world of architecture. Now, researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have demonstrated a new manufacturing process that can create 3D printed metal components with an unprecedented degree of precision. For architecture, this could mean greater control over the customization of the smallest components in buildings, as well as more carefully engineered properties of the larger ones.

Bartlett Students Invent Skeleton-Inspired Structural Material for Lightweight Construction

A team of graduates from the Bartlett School of Architecture at University College London have developed a new hybrid building material designed for use in uniquely challenging construction environments. "Augmented Skin" combines a regimented structural core with a flexible opaque skin, which is coated in PVA to serve as casting formwork for concrete. Inspired by biological skeletal frameworks, the material can be assembled quickly at a minimal cost with maximum flexibility. The project was designed by architecture graduate students Kazushi Miyamoto, Youngseok Doo, and Theodora Maria Moudatsou, and was exhibited at The Bartlett's 2014 graduation exhibition B-Pro.

Ohio State Researcher Team Invents Combined Solar Cell and Battery

A new technology developed by researchers at Ohio State University has the potential to increase the efficiency and decrease the cost of generating and storing the sun's energy. Led by professor of chemistry and biochemistry Yiying Wu, the team has created a combined solar cell and lithium storage battery with an efficiency of electron transfer between the two components of almost 100%, in a design which they believe will reduce costs by up to 25%.

Pratt Institute Students Create Sinuous Screen Wall From Concrete Blocks

Students from the Pratt Institute have created a wall of concrete blockwork... but not like any you've seen before. Challenged by their tutors Lawrence Blough and Ezra Ardolino to produce something highly customized from something highly standardized - the 8-by-8-by-24-inch AAC brick - the students used Rhino software and a CNC miller to create a 96-block screen wall composed of 20 different block profiles. “The earlier stuff I’d done was trying to use as much off-the-shelf material as I could,” said Blough. “Here we decided to really push it, and to take on more of the ideas of mass customization." Find out more about the project at the Architect's Newspaper Fabrikator Blog.

AD Interviews: Benton Johnson / SOM

Inside the Wood Pavilion at this year's AIA Convention, we had the chance to chat with Benton Johnson of Skidmore, Owings & Merrill (SOM) about SOM’s research on using wood for highrise buildings. Although wood is a sustainable and efficient material, it hasn’t entered the world of skyscraper construction yet. However, through their Timber Tower Research Project, SOM has come up with a structural system for skyscrapers that uses mass timber as the main structural material and consequently minimizes the building’s carbon footprint.

Three Self-Healing Materials That Could Change the Future of Construction

Buildings, regrettably, don't last forever. Until recently, the only way to increase a building's lifespan was ongoing maintenance, which can be expensive, time-consuming and in the case of infrastructure such as bridges or roads, inconvenient. Beyond that, periodic replacement of the entire structure was an option, however this is clearly not a sustainable solution, especially considering the amount of CO2-releasing concrete used in modern construction.

"Shell Lace Structure": Tonkin Liu's Nature-Inspired Structural Technique

Continuing recent research trends in the ways nature can inspire new architectural methods and typologies, London-based architecture practice Tonkin Liu in collaboration with engineers at Arup, have developed a single-surface structural technique called Shell Lace Structure. The innovative technique takes advantage of advanced digital design, engineering analysis, and manufacturing tools. Read on to learn about their upcoming book and exhibition that reveals the process behind this nature-inspired material.

The Green Building Wars

Originally published by Metropolis Magazine, this comprehensive analysis by sustainability expert Lance Hosey examines the current disputes within the green building industry, where market leader LEED currently finds competition from the Living Building Challenge, aiming for the "leading edge" of the market, and the Green Globes at the other end of the scale. Arguing for a more holistic understanding of what makes materials sustainable, Hosey examines the role that materials, and material industries such as the timber and chemical industries, can have in directing the aims and principles of these three sustainability rating systems - for better or for worse.

IaaC Students Develop Material System with Responsive Structural Joints

Despite architecture's continued evolution over the course of history, our use of structural materials has remained largely the same since the advent of modern building materials. This reality may be changing thanks to the development of new materials seeking the same kinds of adaptability often found in nature.
