Green Top Ten — Office Buildings
When Perkins + Will recently sought to move its Atlanta offices,
the firm wanted the new facility to serve as a case study for
sustainable design, expressing the culture of the firm.
So, the multidisciplinary design practice purchased a 1986
office building down the street — right across from Richard
Meier's iconic High Museum of Art, and its Renzo Piano expansion —
reconfigured it while retaining most of the structure, and
improved the energy-using systems.
The renovated six-story, 79,000-square-foot (7,300-square-meter)
building at 1315 Peachtree Street in Midtown Atlanta meets the
2030 Challenge and recently earned LEED Platinum certification.
This project is one of four office buildings on the AIA/COTE Top
Ten Green Projects list for 2012, created by the American
Institute of Architects (AIA) Committee on the Environment
(COTE). ArchitectureWeek will also publish the six other
projects on this year's top ten list, which are all buildings
1315 Peachtree Street • Atlanta, Georgia
The facade redesign at 1315 Peachtree Street offered the
opportunity for several favorable changes, including altering
the massing and section of the building, providing connections
between pairs of floors, and adding a fifth-floor outdoor
terrace. The west facade now features low-e glazing and fixed
horizontal and vertical sunscreens.
The building's HVAC system combines radiant heating and cooling
with displacement ventilation. Radiant systems are rarely used
in hot, humid climates, because the warm, moist outside air
would produce condensation on the cool-water tubing.
The design team carefully adjusted the amount of exposed
concrete, the size and spacing of radiant mats, and the number
and locations of operable openings, and the firm reports that
the system has worked as designed.
No less important than the project's green design goals was a
commitment to support the firm's own design work. The Perkins +
Will office space, located on the building's top four floors,
accommodates work at individual workstations, while also
providing several kinds of spaces to facilitate group work,
including team rooms where projects "live."

Basics - The Skyscraper Today
by Kate Ascher
When it comes to buildings, size matters — more so today than ever before. Look up in the heart of any of the world's major cities and your eyes will likely alight upon a towering, glass-walled structure — if not literally scraping the sky, then certainly pointing in that direction.
The proliferation of skyscrapers is accelerating rapidly. Prior to the year 2000, fewer than 250 buildings around the world reached higher than 600 feet (180 meters); between 2000 and 2009, that number more than doubled.
And it continues to grow faster than ever before: at the beginning of 2010, almost 400 new skyscrapers were under construction around the world. The downturn in the global economy that began in 2008 did little to dent the world's appetite for tall buildings.
Not only are there more tall buildings, but they are in more places. Once a purely American phenomenon, the construction of skyscrapers is now very much a global one. Of the 38 skyscrapers over 600 feet (180 meters) completed in 2009, 22 of them were in Asia and seven were in the Middle East. The "tallest" metropolis in the world is in Asia: the combined height of Hong Kong's skyscrapers is roughly three times that of New York City's.
So prolific are these towers today in the world's metropolises, and so enthusiastic are their planners, that there are now adjectives that differentiate between them: "tall" is often used to describe skyscrapers between 500 and 1,000 feet (150 to 300 meters); anything above that is considered "supertall." Even measuring the building is now a science: do you measure it from street level or from the basement? To the highest occupied floor or to the top of its crown?
Some readers may wonder why we should care how tall these towers are or how many of them exist. Are they not just the product of speculation and greed on the part of a handful of wealthy developers? Or the modern incarnation of some age-old form of civic pride? The answer is no — they are much more than that.
VMZINC: The Versatile Choice for Roofs and Walls
The VMZINC Standing Seam Panel System is a versatile, economical technique applied to roofs and walls. It can be machine- or hand-produced, depending on the design. Available in five colors, it accommodates lines and shadows and is particularly suitable for very large surfaces and for structures located in harsh climates.
It's fast, easy, private, and secure.

Product News - Mini Spider Cranes
The GGR Group offers Unic mini cranes. This line of
compact spider cranes offers heavy lifting power in
situations with limited space or access, providing a
cost-effective, flexible alternative to traditional
tower cranes. A Unic URW-706 crane has recently been
working atop The Shard skyscraper in London, designed by
Renzo Piano. Positioned at the 87th floor (pictured), it
lifted glass facade panels from below. Measuring only
1.67 meters (5.48 feet) wide and weighing 7.9 metric
tons (8.7 tons), the crane can lift up to 6 metric tons
(6.6 tons). Controlled from the operator's driving seat
or with a radio remote control for precise load

The metric unit of force, the _____________, is defined
as the force that produces an acceleration of one meter
per second per second when exerted on a mass of one
kilogram. Named after an English philosopher and
mathematician, what is this unit called?
The biobrick was patented by Englishman Thomas Shaw in
1889. How does its manufacture differ from that of a
regular clay brick?
Classic Home 047 — Six-room brick house, by Olsen & Urbain
"Here is a popular plan for a six-room house of brick construction. From the entrance at the side of the house one may go into the living room, dining room, or kitchen. There is also an entrance from the porch into the living room, which extends across the entire front of the house and has an open fireplace flanked by built-in bookcases with small windows above. The rear porch is large enough for a dining porch and above this is a sleeping porch.
