Cool Roofs Stack Up," by staff, is an article in
the June 2012 issue of Buildings. Three buildings in New York City were
selected for the installation of one of three different types of white roof
surfaces in a three-year field study that is part of NYC CoolRoofs, a program to
lower the city's emissions. The
white roofs were compared to one another and to a black roof for summer
temperatures and winter emissivity.
HVAC/R (HEATING, VENTILATION, AIR CONDITIONING, AND REFRIGERATION)
The following three articles appeared in the June 2012 issue of
Predicting Boiler-Controller Energy Savings,"
by John D. Sullivan, PE, Alzeta Corp., explains why a common method of testing
add-on boiler controllers can suggest more energy savings than are actually
going to be realized. His solution
to this problem is an alternative, and more accurate, testing method which he
Deaerator," by Gary Wamsley, PE, CEM, JoGar Energy Services,
offers an opportunity to solve a puzzle: why was a boiler tripping offline at
certain times? For those wanting to
figure out the answer, a caution: the answer begins in the third paragraph from
the top (with the heading Problem Analysis) and continues with a detailed
Efficiency with Hydronic Boilers," by Alan Wedal Cleaver-Brooks,
makes the case for highly-efficient hydronic boilers.
Navy's Great Green Fleet Demonstration Is Underway,"
by the U.S. Navy, was posted July 17, 2012, on the
Biodiesel Magazine website.
It describes the demonstration just begun in the Navy's Pacific Rim area
whereby a number of different Navy vehicles are powered by a variety of fuels
that are not petroleum based. The
fuels are either nuclear or bio-based.
For the Navy, security is the driver for eliminating its dependence of
A Defining Framework for
Intelligent Efficiency is a brief description of
ACEEE's (American Council for an Energy-Efficient Economy) Research Report E125
of the same name, published June 2012; it was jointly-authored by Neal Elliott,
Maggie Molina, and Dan Trombley. The systems include those in all building
types, industrial processes, and transportation systems. The brief description includes a
link to the 63-page report; free registration is required to view the full text.
New Report Highlights Importance of Clean Energy Policy, As Well As Need for
Reform is a blog entry by Cai Steger, posted April 18, 2012. It describes
and links to Beyond Boom & Bust: Putting
Clean Tech on a Path to Subsidy Independence, a new 65-page report whose
several authors are from the Breakthrough Institute, the Brookings Institution,
and the World Resources Institute.
The in-depth report provides information on the many federal inducements for
clean energy from 2009 through 2014.
It, further, suggests policy options to consider as government subsidies end.
RESIDENTIAL EFFICIENCY STRATEGIES
Stay Cool, Save Money is a website, revised (and re-named) seasonally, from the
Energy Efficiency and Renewable Energy Office of the U.S. Department of Energy. The site is now offering many tips for
energy savings for the warmer months.
The following three articles were published in the June 2012 issue of
We Really Building the Best Wind Turbines?"
was co-authored by Marko Yanishevsky, MASc PEng, Institute for Aerospace
Research National Research Council Canada, Ottawa, ON, Canada; and by Glen Lux,
BSc. Eng., and CEO of Lux Wind Power Ltd., Saskatoon, SK, Canada. The authors feature the Vertical Axis
Wind Turbine (VAWT) which has no tower and uses cables to reinforce the blades.
Practice Machining of Wind Power Components"
was written by Brent Godfrey, Industry and Applications Specialist with Sandvik
Coromant. Better machining is said
to result in superior machined parts which lead to less downtime, efficient
operation, and increased productivity.
– Lengthening the Design Envelope" was authored by Kevin Cadd,
Technical Programe Manager, Gurit UK.
The author presents a resin technology for blades that speeds curing and
gives exothermic control for the spars as well as the blades. Other benefits are described.
