CO2 Use Growing

MILWAUKEE—Roundy’s Pick ’n Save
grocery is installing a refrigeration
system that uses carbon dioxide as
its refrigerant in a store being built
in Menomonee Falls, Wis.
The new system, in part, reflects
a worldwide shift toward naturally
occurring refrigerants that are
considered more environmentally friendly than their chemical
counterparts.

ATLANTA—Why do some people thrive
when the temperature rises, while
others can’t think straight without
air conditioning? Variables such
as where a person grew up, their
amount of body fat and even their
hydration level can influence how
they feel in hot or cold temperatures,
says Michael Sawka, Ph.D., a professor at Georgia Tech.
People who avoid going outside
when it’s hot—preferring to move
straight from an air-conditioned
office to air-conditioned transportation to a well-chilled restaurant, store
or home—can quickly lose their ability to acclimate, Sawka says. Without
regularly experiencing heat, the body
becomes less efficient at sweating and
has more difficulty increasing blood
flow to the skin—functions that help
the body cool itself.
Most people have greater difficulty adapting to cold, says Sawka.
Some can eventually learn to ignore
uncomfortably low temperatures, but
“it’s a lot more dependent on body
fat and the size of your body.” Since
few people are exposed to extremes,
most people have “a narrow range of
comfort.” Source: Wall Street Journal

WASHINGTON—Boston achieved the top spot
in a newly released ranking of 34 of
America’s largest cities because of its efforts to cut energy use and costs. The
other highest-scoring cities in The
American Council for an Energy-Efficient Economy’s (ACEEE) “2013 City Energy Efficiency Scorecard” are Portland,
Ore.; New York; San Francisco; Seattle;
and Austin, Texas. The report also includes recommendations and strategies
for all cities to lower energy use. Source:

absolute World towers wins Emporis skyscraper award.

Towers Win Award
HAMBURG, Germany—This year’s Emporis
Skyscraper Award has been presented to the Absolute World Towers
in Mississauga, ON, Canada. The
two towers were selected by a jury of
experts from over 300 skyscrapers.
Absolute World Towers was
designed by MAD and Burka
Architects. They won over the jury
primarily through their design: “The
way the two structures twist organically by up to 8 degrees per floor is
not just a superb technical achievement, but also a refreshing change
to the set forms of high-rise routine,”
said the jury. Source: Emporis
“It’s huge,” said Doug Reindl,
an engineering professor at the
University of Wisconsin-Madison.
“Refrigeration is critical to food safety
and maintaining product quality.”
The system has been used successfully for a number of years. There are
only about five or so grocery stores in
the U.S. that use CO2.

ACEEE

PALATINE, Ill.—Forty-three percent of energy leaders say their investment in energy efficiency next year is projected to
be more than it was last year, according
to a recent survey by Schneider Electric.
Twenty-two percent said their projected investment would stay the same, and
10% reported their investment would be
less than last year. Source: Schneider Electric
WASHINGTON—Honeywell announced that a
new study has found that its HFO-1234yf
refrigerant has a global warming potential (GWP) that is four times lower
than previously thought. The independent peer-review study in Reviews of
Geophysics found that HFO-1234yf had
a GWP of less than one. Earlier studies
had calculated a GWP of four. CO2 has a
GWP of one. Source: JARN
SHANGHAI—The U.S. Green Building Council says that China is now the third-largest LEED market. USGBC attributes the
growth of LEED to the rapid economic development and the willingness of
the Chinese people to accept changes in
building practices. Source: USGBC
SEOUL—The South Korean government has
granted approval to begin construction
on the world’s first “invisible” tower. Designed by U.S.-based GDS Architects, its
invisibility illusion will be achieved with
a high-tech LED facade system that uses
a series of cameras that will send realtime images onto the building’s reflective surface.

Addendum
A news article in the September edition
should have recognized Cosentini Associates
as the designer of the innovative envelope for
the Shanghai Towers.
