The Past, Present, and Future of the Vacuum Insulated Glazing Technology

In practice, for equivalent levels of thermal conductance, the VIG is much thinner in profile, considerably lower in weight, greater durability in thermal and mechanical performance over a +25 yr service life, and since it can be paired with all existing technologies to produce hybrid designs, has a potential U-value lower limit at about 0.2 W m-2 K-1. Since the original VIG invention (reported in the early 1990’s) of The University of Sydney, numerous research efforts around the world have led to a fundamental understanding of the critical design and production issues. This has resulted in innovative VIG designs, a range of innovations in the production components, and as many as 14 manufacturing plants over three continents. The purpose of this talk is to review the VIG technology background, and then provide an overview of the current status of the technology. And then finish with the current road map for future advances in unit design, component material innovation and manufacturing potential. Currently, in our developed nations, building energy consumption has grown to a level that is reaching beyond 40% of total final national energy consumption [1]. Much of this energy us...

Chinese online shoppers shatter Cyber Monday records on ‘Double 11’

BEIJING — China’s “Double 11” day makes the United States’s Black Friday and Cyber Monday look tame. In the first 68 seconds of Nov. 11, Chinese consumers had spent $1 billion snapping up bargains online. Within the first hour, they’d spent $14.3 billion — about half the total recorded last year during the Thanksgiving shopping season in the United States. Even though the Chinese economy is flagging — or perhaps because the Chinese economy is flagging — consumers are eager for bargains on the most frenzied shopping day of the year. “There were so many discounts available that it makes me feel that I have to buy something, or I would be missing out big-time,” said Zhang Hui, 31, who works at a public-relations firm in Beijing. She snapped up a pair of boots and an overcoat on Taobao for a total of $142. Nov. 11 has long been celebrated in Asia as “singles’ day” — because the 11/11 date looks like four singles — and has been commandeered in Japan and South Korea by Pocky and Peppero, respectively, the makers of chocolate sticks that look like ones. It is marketed as a kind of anti-Valentine’s Day, where singles can spend on themselves. China began marking the day in the 1990s, whe...
