Glass dome to highlight museum

Bentonville, AK is known as the home of Walmart, but the city will soon be sporting a new attraction. The Crystal Bridges Museum of American Art will welcome a new structure – a geodesic dome with 61 glass “eyes.” The “Fly’s Eye Dome” will sit on the museum’s north lawn, near a house built by American architect Frank Lloyd Wright.

The geodesic dome was designed by Buckminster Fuller, who was inspired by a drawing of a fly’s eye. The dome is one of three designed by Fuller, and was previously displayed in Los Angeles as part of the city’s Bicentennial celebration in 1981. It was most recently displayed in Toulouse, France in 2013. The museum acquired the dome as a permanent exhibition.

The structure is made from glass and fiberglass. The materials appealed to Fuller because they were both lightweight and strong. The dome was the largest of three prototypes built by Fuller. Two smaller domes, measuring 12 feet and 24 feet were also constructed. Fuller initially designed the dome as a cost-effective, lightweight and strong housing solution. According to Fuller, a geodesic dome would cost less to build and transport, and could be erected quickly.

The museum also acquired Fuller’s notes on the project, and has shared those documents with the University of Arkansas. Although the prototype domes were built, they weren’t fully functional homes, since they lacked a viable design for ventilation. Fuller also hadn’t developed a plan for the dome’s interior layout, so the prototype spaces are wide open.

Like the Frank Lloyd Wright home, the Museum says that it acquired the Fly’s Eye Dome as an example of “uniquely American architecture.”

Recycling commercial glass

Even though glass is a very popular construction material, most commercial glass is already installed in existing structures. Because buildings are intended to last for a long time, the original glass often stays in place until someone undertakes the cost of remodeling or rehabilitation, or the building gets demolished.

Renovations, remodeling and rehabilitation all present an excellent opportunity to update commercial glass. The primary motivator for such an update is usually energy efficiency. In rehab situations, it may be necessary to replace windows that have been broken, especially if a building has been empty for quite some time.

Aside from these special situations, updating the windows in a building usually isn’t a high priority, largely because of the expense involved. When windows are removed or replaced, they’re usually carted off to the landfill, as part of the larger collection of construction debris.

When buildings are demolished, there is little incentive to remove the windows prior to demolition. There’s also very little financial incentive to do so. The market for recyclable glass is very small, so it costs less and takes less effort to ship old glass to the landfill.

Modern commercial windows rarely contain ordinary glass. Laminated glass, tinted glass and safety glass dominate the commercial construction landscape. Other specialized glasses – such as low-e glass – also have coatings and other additives that make recycling difficult, if not impossible.

While these types of glasses can’t be recycled, they may find additional use in fiberglass products or as components of concrete, asphalt or as landfill cover.

Gorilla glass goes for a car ride

Glass is naturally heavy, but Corning says that the automotive version of its signature tough product is lightweight and will support manufacturers’ desire to incorporate displays into the driver’s visual space. The company says it will offer Gorilla Glass for both structural and interior automotive applications.

Automakers are under significant pressure to improve gas mileage, and one way to do that is by reducing the weight of the vehicle. According to Corning, automotive Gorilla Glass is one-third lighter than conventional auto glass. Depending upon the vehicle size and its design, windows can add 100-150 pounds to the finished weight of a vehicle. By reducing the weight of the vehicle, automakers can not only improve gas mileage, but also reduce the vehicle’s emissions.

Reducing the weight of the glass also has other design and performance benefits. Reduced weight can improve acceleration and vehicle handing. Corning also says that windshields made of Gorilla Glass can eliminate 50% of the vehicle glass breakage that occurs today. That could reduce the total cost of ownership of a vehicle, and could also reduce comprehensive insurance costs for drivers.

Corning also says that automotive Gorilla Glass is clearer than conventional auto glass. The clarity of the glass also enables automakers to incorporate larger, brighter head-up displays. In addition, Gorilla Glass can be more easily formed into curves and 3-D shapes, allowing the designers enormous flexibility in displays, controls and the outward appearance of the vehicle. The company also says that its glass will provide better, more responsive touch controls.

New paint-on coating improves glass efficiency

Researchers at Berkeley National Labs are working to develop a paint-on coating that reflects heat. If successful, the coating could be added to existing windows for about one-tenth the cost of conventional heat-reflective glazes. The researchers even speculate that the coating could be applied by homeowners as a do-it-yourself project.

The coating will be designed to selectively reflect infrared light waves without significantly reducing visible light. Like many energy-efficient coatings, the Berkeley coating will also be designed primarily for use in southern and western climates. These buildings tend to use a significant amount of electricity for air conditioning.

The goal of the development is to create an inexpensive, easy-to-use coating. If they succeed, the coating could reduce energy consumption by as much as 35 billion KWh and 24 billion pounds of CO2 emissions annually. The team’s goal is to create a coating that could be applied for about $1.50 per square foot.

To create the coating, the team will work with a type of polymer known as a “bottlebrush” polymer. The unique shape of the polymer – a rigid spine with bristles that extend from the sides – could help reflect infrared light, while allowing visible light to pass unimpeded.

The work is being funded by the US Department of Energy, and will allow the team to develop, refine and test the coating. Another element of the project is to determine how best to scale production, maximize the coating’s efficiency and distribute the finished product.

NYU’s Billion-Dollar Glass Building

The all-glass façade is both practical and symbolic. When the university sought to expand its footprint beyond its current campus, its plans were met with stiff opposition from its nearby neighbors. The issue was litigated and the University prevailed. The all-glass façade is meant to help heal the rift that was opened between the University and the surrounding community, some members of which wanted the land to be used as a park. As a nod to the community, the building will also feature about 8,000 square feet of space designated for community or public use.

The University acquired the space on which the new building will sit in the 1960’s. To create enough space for the new “super building”, the University needed to demolish an existing recreation building, which was completed in August 2016.

Even though the new building’s size seems immense, it’s actually only about 80% of what the city would allow on a parcel of that size. The building’s glass façade will provide a significant amount of natural light. It will also have a “green roof” and low-flow plumbing, as well as a rainwater runoff retention system.

According to NYU, the building is much needed and long overdue. While the facility does replace an athletic and recreation building, it also expands the available instructional space and relieve currently overcrowded classrooms. According to NYU, the building will be ready for use in 2021.
