Consumption: Acid Esterification vs.
Glycerolysis: Which Really Consumes More Energy?"
was written by Kirk Cobb, Senior Process Design Engineer, Superior Process
Technologies Inc.; it was published in the July/August 2012 installment of
Biodiesel Magazine. It takes
issue with "A Critical
Component," which was
authored by Erin Voegele, Associate Editor, Biodiesel Magazine and which
appeared in the January/February 2012 issue of the same journal. The Voegele article author, relying
on identified practitioners in the field of biodiesel production, uses a table
from JatroDiesel that includes the information questioned by Cobb. The Cobb article asserts that while
acid esterification uses little energy initially, this advantage is cancelled
out by the resulting creation of acidic methanol that requires a great deal of
energy to neutralize.
The following six, case studies were included in the July+August issue of
Plant," by Mary
Pepchinski, is a case study of a plant in Southern Germany that meets
high-performance goals in two aesthetically-interesting buildings designed by a
well-known Milanese architectural firm.
To ensure profitability, the German government has a policy of
encouraging renewables development by guaranteeing energy producers of
renewables a specified compensation for a specified period of years.
Central Platte Campus," by Asad Syrkett, shows some of the
major features of this LEED-Gold municipal campus. One feature for the vehicle
maintenance shop includes the use of radiant floor heating and the heat recovery
of exhaust air, both of which help mitigate ventilation problems and reduce
Seaport Farmers' Market," by Alanna Malone, is a two-Web-page
case study showing the features that add up to a very sustainable structure for
a market that has been conducting business since 1740 without a break, making it
the oldest of its kind in North America.
The features include energy generated from building-integrated wind, PV
panels, and geothermal.
Additionally, the market has a green roof, and its operable windows are double
glazed and argon filled. Energy recovery
ventilation is employed to heat the incoming air in the winter.
by Russell Fortmeyer, describes the Melbourne, Australia, office building that
has a playful exterior and has, to date, received the highest number of LEED
points toward platinum certification than any other, and the highest possible
Green Star ratings. Interestingly,
while the LEED system measures energy by its cost, Australia's Green Star system
measures energy by its carbon content.
It is pointed out in the article that, as a result, natural gas would
achieve more points toward Green Star certification than electricity if the
electricity were coal-based.
Francisco International Airport Terminal 2,"
by William Hanley, describes a rebuilt terminal that was designed with a sense
of place, ease of use, and a number of energy-savings features that include
daylighting, electricity controls, displacement ventilation, and roof PV.
Office Building," by Nadav Malin, is a two-Web-page
case study of an office building in the challenging climate of
Hyderabad in Southern India, where the weather is like "Houston half the year
and Phoenix the other half." An
attempt to use in-slab radiant cooling met with a great deal of resistance
because, in India, it was only used in outdoor palaces. It was thought to be inadequate to
handle the high humidity of Hyderabad summers in an enclosed building. A decision was made to split the
building into two parts for the purpose of comparing radiant cooling to the more
traditional VAV (variable air volume) approach.
The best of both types of systems were installed so the comparison would
be fair and of value. In all areas,
radiant cooling won hands down as verified by an independent third party. The initial cost of the two systems
was about the same – the project's consulting engineer, who is from San
Francisco, believes the high initial cost of radiant cooling in the United
States is unreasonable.
Big: Building the Largest Ever Energy Efficiency Project"
was written by Joel Scruggs, Public Affairs Specialist, Bonneville Power
Administration (BPA); it was posted August 16, 2012, on the U.S. Department of
Energy website, Energy.Gov. A pulp and paper mill (NORPAC) in
Longview, Washington is to become so energy efficient that it will save 12
megawatts of electricity a year.
Funded by BPA and the local Cowlitz County Public Utility District, the project
includes two phases. Phase one,
which employs new equipment for treating wood chips prior to refining, has been
completed. Phase two, which is to
use new screening equipment in the refining process, is underway.
The following two articles appeared in the July 2012 issue of
Wires and Cables Are Not Created Equal," by Sherri Mabry, cautions against the
practice of some wind developers who buy cheaper products that fail early and
often, leading to a much lower ROI (return on investment) than would be the case
for their higher-quality counterparts.
Pitch Control and Its Impact," by Sherif El-Henaoui, Ph.D.,
addresses the technical difficulties to be overcome when designing for larger
turbines with longer blades and higher towers.
Pitch control systems are essential to their success.
Wind Energy Education and Training Programs is a Web page of Wind Powering America,
a program at DOE's Office of Energy Efficiency and Renewable Energy. It shows the sites of training
programs around the country. In
Washington State, there are four that are operational and one in the planning
stage; in Oregon, all five of its programs are operational; Idaho and Montana
each have three programs in operation; California has eleven operating programs.
