Project: Oakland Airport Connector - Doolittle BART Station in Oakland, Calif.
Architect: ED2 International
Glazing Contractor: Bagatelos Glass
Products: SuperLite II-XL 60 IGU in GPX Framing with Sunshade Connection
Why it’s unique: Sunshade connections are not typical with fire rated assemblies
For the Doolittle Maintenance Facility, SAFTI FIRST provided 60 minute, fire resistive wall openings in the exterior using SuperLite II-XL 60 insulated with low-e glazing in GPX Framing with a clear anodized finish. SAFTI FIRST engineered a connection that allows the structural elements of the GPX Framing System to support an integral sunshade system, instead of being hung in front of it.
The framing covers were notched around the brackets to create a seamless connection. The connection was also kept in front of the waterline to avoid a potential breach, keeping the system air and water tight. Other manufacturers would have to go through and behind the glazing pocket to get to the structure, creating a challenge during the fabrication and installation phases.
The potential for water penetration increases significantly once you punch a hole in your framing and glazing pocket. By using the SuperLite II-XL 60 IGU in GPX Framing, the architect was able to achieve the aesthetic and code requirements of the application while keeping the whole system air and water tight.
The Doolittle Bart Station is one of the first installations of the GPX System with sunshade connections, which also include SLCC New Instruction and Administrative Building in Salt Lake City, UT. While it is a fairly new offering, it is quickly gaining attention and interest in the building community. Sunshades are commonly used in building to control the amount of direct sunlight through exterior windows.
When the location of the exterior windows also need to meet fire rated requirements due to property lines, etc., it is good for designers to know that they have an option that combines both.

Architecture Billings Index: inquiries for new projects remain extremely high
The new projects inquiry index was 61.7, down slightly from a nearly three-year high mark of 62.3 in September, according to the Architecture Billings Index (ABI). However, the ABI dropped nearly two points in October; the October ABI score was 48.7, down from a reading of 50.4 the previous month. The ABI reflects the approximate nine to 12 month lag time between architecture billings and construction spending.

Brazil Olympics spurring green construction
Brazil's green building industry will expand in the coming years, spurred by construction of low-impact venues being built for the 2016 Olympics. The International Olympic Committee requires arenas built for the 2016 games in Rio de Janeiro meet international standards for low-carbon emissions and energy efficiency. This has boosted local interest in developing real estate with lower environmental impact than existing buildings. The timing couldn’t be better: the Brazilian government is just beginning its long-term infrastructure expansion program.

CityCenter’s new Harmon Hotel targeted for demolition
MGM Resorts officials want to demolish the unopened 27-story Harmon Hotel—one of the main components of its brand new $8.5 billion CityCenter development in Las Vegas. In 2008, inspectors found structural work on the Harmon didn’t match building plans submitted to the county, with construction issues focused on improperly placed steel reinforcing bar. In January 2009, MGM scrapped the building’s 200 condo units on the upper floors and stopped the tower at 27 stories, focusing on the Harmon having just 400 hotel rooms. With the Lord Norman Foster-designed building mired in litigation, construction has since been halted on the interior, and the blue-glass tower is essentially a 27-story empty shell.

Landscape architecture challenges Andrés Duany’s Congress for New Urbanism
Andrés Duany, founder of the Congress for the New Urbanism, adopted the ideas, vision, and values of the early 20th Century landscape architects/planners John Nolen and Frederick Law Olmsted, Jr., to launch a movement that led to more than 300 new towns, regional plans, and community revitalization project commissions for his firm. However, now that there’s a societal buyer’s remorse about New Urbanism, Duany is coming up against a movement that sees landscape architecture—not architecture—as the design medium more capable of organizing the city and enhancing the urban experience.

Just for fun: Words that architects use
If you regularly use such words as juxtaposition, folly, truncated, and articulation, you may be an architect. Architects tend to use words rarely uttered during normal conversations. In fact, 62% of all the words that come out of an architects mouth could be replaced by a simpler and more widely known word, according to this “report.” Review this list of designer words, and once you manage to work them into daily conversation, you’re on your way to becoming a bonafide architect.

NFRC approves technical procedures for attachment product ratings
The NFRC Board of Directors has approved technical procedures for the development of U-factor, solar heat gain coefficient (SHGC), and visible transmittance (VT) ratings for co-planar interior and exterior attachment products. The new procedures, approved by unanimous voice vote last week at NFRC’s Fall Membership Meeting in San Francisco, will add co-planar attachments such as blinds and shades to the group’s existing portfolio of windows, doors, skylights, curtain walls, and window film.
