How Physico-Realistic Rendering Helps Architects Choose the Right Glass for Facades

10:30 - 21 October, 2016

The physical properties of glass are invaluable and unequaled when it comes to the architect’s material palette. From the time of the cathedrals and the the brilliantly colored stained glass that served a functional and didactic purpose, to the modernist liberation of the floor plan and the exquisitely-framed horizontal views provided by ample windows, architects have turned to glass to achieve not only aesthetic but performative conditions in their projects.

Today, Architects face an increasing array of choices in specifying and designing with glass for building facades, as glass manufacturers propose a greater variety of colors, textures and patterns than ever before. A wider range of coatings and treatments has also been developed, allowing for a finer selection of glass panes with a combination of light transmittance, reflectance and absorption to meet the needs of outstanding architectural projects. These options affect the aesthetics and energy performance of the glass, and therefore of the overall building.

Thanks to advanced calculation tools, energy performance can now be anticipated accurately, but the graphic representation of glass is still a challenge, and yet a crucial need for architects.

Even as modernism promoted the transparency of glass architecture, many within the movement were conscious of the monotony of large glass facades, with even Mies van der Rohe using elements such as his trademark mullions to break up his facades. But in the years since, countless uniform structural glazing skyscrapers have emerged and bored urban citizens. In response to this, unconventional reinterpretations of facades have gained interest.

Accompanied by the belief that light and brilliance could help in creating iconic architecture and a better human world, glass and metal have been innovatively transformed to create crystalline images. As a result, the locus of meaning in architecture has shifted from the internal space-form towards the external surface.

Los Angeles' Glass-Bottomed "Skyslide" Opens to the Public

16:00 - 28 June, 2016

Found in places as diverse as the Zhangjiajie Grand Canyon, Willis Tower, and Tokyo Skytree, glass bottom observation decks have become the favorite engineering marvel of thrill seekers looking for a new perspective on the world. Now, the U.S. Bank Tower in downtown Los Angeles has upped the ante for adrenaline-spiking structures – affixing a glass side to the building’s facade. Spanning from a window on the 70th story to a terrace on the 69th, the 45-foot-long chute opened to the public on Saturday, providing those brave enough to ride it with unprecedented views of the city.

Discovered by archaeologists in civilizations as old as ancient Egypt and Mesopotamia, fritted glass is hardly a new technology. Yet thanks to its energy-saving abilities and the smooth, gradient aesthetic it produces, fritted glass has seen a rebirth in contemporary architecture.

Frit itself is a ceramic component that can be laid out into an assortment of patterns, most typically consisting of dots or lines. These patterns can then be silk-screened onto annealed glass using frit paint. Then, the glass is fired in a tempering furnace, which strengthens and improves the safety of the glass under thermal stress. The resulting product is glass of determined transparency that, when used in building facades, can reduce solar heat gain and even make buildings more visible and less deadly for birds.

Jyväskylä, a city whose status as the center of Finnish culture and academia during the nineteenth century earned it the nickname “the Athens of Finland,” awarded Alvar Aalto the contract to design a university campus worthy of the city’s cultural heritage in 1951. Built around the pre-existing facilities of Finland’s Athenaeum, the new university would be designed with great care to respect both its natural and institutional surroundings.

The city of Jyväskylä was by no means unfamiliar to Aalto; he had moved there as a young boy with his family in 1903 and returned to form his practice in the city after qualifying as an architect in Helsinki in 1923. He was well acquainted with Jyväskylä’s Teacher Seminary, which had been a bastion of the study of the Finnish language since 1863. Such an institution was eminently important in a country that had spent most of its history as part of either Sweden or Russia. As such, the teaching of Finnish was considered an integral part of the awakening of the fledgling country’s national identity.[1]

MIT Research Team Develops Affordable Smart Glass Alternative

17:00 - 27 January, 2016

When it comes to scrutinizing architectural materials for their energy efficiency, one offender stands out above the rest: glass. Windows and curtain walls act as one of a building’s main outlets for heating and cooling losses, and as society advances into its more environmentally-conscious future, new, passive solutions will need to be developed to mitigate buildings’ energy footprints. In recent years, various smart glass technologies have been designed to automatically regulate light and heat based on environmental conditions. Yet their high price tags have prevented them from achieving widespread application. Now, a team of MIT researchers may have discovered an alternative to smart glass that could come at an affordable price.

These Glass Walls Slide Around Corners to Disappear From View

16:30 - 2 December, 2015

One of the most popular tropes of Modernist architecture was the goal of dissolving the external boundaries of the home, connecting residents to nature through the use of large glass walls in order to "bring the outside in." Nowhere was this project more thoroughly realized than in Mies van der Rohe's 1930 Villa Tugendhat, where an entire side of the glass-walled living space could, if the user wished, be dropped through the floor and the house become open to the elements. Elegant though it was (especially in 1930), Mies' solution didn't catch on, limited by the fact that it required an electric motor and a basement below in which to store the disappeared facade.

These days, while countless houses incorporate glass walls that fold, slide, or swing open, few offer the bravura of Mies' design, choosing to move the glass off to the side rather than making it disappear entirely. This year though, window and door manufacturer Vitrocsa may have turned a corner in the provision of vanishing glass walls with its "Turnable" system.

In an era when both environmental comfort and sustainability are key concerns in architecture, the tendency to cover buildings entirely in glass is among the most criticized and controversial traits of contemporary architecture, as all-glass buildings often guzzle energy thanks to their demanding cooling and heating requirements. Over the years, a number of fixes for this problem have been attempted, including smart glass solutions that allow users to modify the transparency of the window. The problem with this solution, however, is that smart glass is unable to block infrared (heat) transmission without ruining the very thing that makes glass attractive in the first place: its transparency to visible light. That conundrum may soon be a thing of the past, though. As reported by Phys.org, a team of researchers at the Cockrell School of Engineering at The University of Texas at Austin have developed a new smart window technology that allows users to selectively control the transmission of light and heat to suit their requirements.

This (terrifying) 300-meter-long bridge is the first in China to be made of all glass. Suspended 180-meters above ground between two cliffs at Hunan's Shiniuzhai National Geological Park, the Haohan Qiao - Brave Men's Bridge - was originally meant to be wood, before being constructed with 24mm thick glass that is 25 times stronger than normal.

"The bridge we build will stand firm even if tourists are jumping on it," said a worker to China News Service. "The steel frame used to support and encase the glass bridge is also very strong and densely built, so even if a glass is broken, travelers won't fall through."

This Improvement to Channel Glass Makes Curved Glass Walls Easier than Ever

A lot of architects love glass. A lot of architects love curves too. The two can be combined, but in most cases this is a highly bespoke and expensive process, with individual sheets of glass being heated in a kiln over a mold created especially to fit the desired curve. Cheaper options are available though, and one common approach is to use smaller sections of flat glass - often a U-shaped channel section - angled to approximate a curve.

But this strategy also leads to a problem: as the desired curve gets tighter, the gaps between the glass segments get more and more apparent and less efficient as enclosure. To address this problem, German designer Holger Jahns has created "c--c," an update to standard U-shaped channel glass which can be fixed together at any angle and create any curve without gaps appearing between the panels.

Mediated Matter's New Platform 3D Prints Glass with Stunning Precision

13:22 - 20 August, 2015

Glass can be molded, formed, blown, plated, sintered and now 3D printed. Neri Oxman and her Mediated Matter Group team has just unveiled their new glass printing platform: G3DP: Additive Manufacturing of Optically Transparent Glass. A collaboration with the Glass Lab at MIT, G3DP is the first of its kind and can 3D print optically transparent glass with stunning precision. 

"G3DP is an additive manufacturing platform designed to print optically transparent glass," Oxman told ArchDaily. "The tunability enabled by geometrical and optical variation driven by form, transparency and color variation can drive; limit or control light transmission, reflection and refraction, and therefore carries significant implications for all things glass: aerodynamic building facades optimized for solar gain, geometrically customized and variable thickness lighting devices and so on."

Paris has approved its first tower in over 40 years; the city council has agreed to move forward with Herzog & de Meuron's 180-meter-tall "Triangle Tower" - or "Tour Triangle" - after initially rejecting the proposal last year. The controversial plans have been the center of an intense debate since its unveiling in 2008 on whether or not Paris should preserve its 19-century skyline. 

As Gizmodo reports, the Swiss architects sold the tower to the city by claiming its glass facade will "disappear" into the skyline.

“Almost everything the architects say has one message: This building is invisible,” as Foreign Policy pointed out last year. “As if to reinforce this strange duality, the renderings omit Paris’s one true existing skyscraper: the wildly unpopular Tour Montparnasse, built in 1973.”

With the demands of sustainability today placing tight restrictions on performance metrics such as how airtight a building is, one of the sacrifices that often has to be made is user control. Windows are often no longer openable; shades and blinds often replaced with non-openable louvers. In recent years new technology such as smart glass (sometimes called "switchable glass) has promised a modicum of compromise, allowing windows to be tinted on demand. But smart glass is limited - it's either on or off, clear or tinted.

Until now, that is. At the AIA convention in MaySageGlass revealed a range of innovations that greatly increase the options available to designers when specifying smart glass.
