ENERGY OPPORTUNITY: OAK RIDGE NATIONAL LABORATORY IS SOLICITING
FEEDBACK ON BUILDING ENERGY EFFICIENCY TECHNOLOGIES AND WILL
RECOGNIZE THE BEST ONE AT A SEPTEMBER 2015 EVENT. SHARE YOUR
INSIGHTS AT BUILDINGS.IDEASCALE.COM.
Manufacturers Recognized by EPA
The EPA has announced that
70 manufacturing plants have
achieved ENERGY STAR cer-
tification in 2014. The manufacturers’
efficiency measures have collectively cut
energy bills by $725 million, reducing
greenhouse gas emission by over 8 million
Among the winners include plants from
cement manufacturing, auto assembly,
corn refining, food processing, glass
manufacturing, pharmaceutical manufacturing, and petroleum refining industries.
While ENERGY STAR certification is
available for most types of facilities, the
EPA is also working to create industry-specific ENERGY STAR plant benchmarking tools to give facility managers an
accurate, reliable way to measure their
building’s performance against the rest
of the industry. Tools are currently in
development for over 20 manufacturing
Additionally, ENERGY STAR provides
seven tips for manufacturing facilities to
start the energy management process:
1) Commit to Continuous Improvement – Companies that end up seeing
financial returns on their energy
efficiency investments are constantly
striving to top their own achievements.
Don’t give up after that first victory.
2) Assess Performance – Be sure that
you’re periodically assessing energy use
and performance within facilities. All
the improvements in the world won’t do
much good if you can’t verify the cost
savings associated with their implemen-
3) Set Goals – Goals for energy performance should be made clear to help
guide daily decision-making. Be sure
you determine the scope of the project
and potential for improvement when
making the goals to ensure that they’re
both meaningful and achievable for your
4)Create an Action Plan – Goals are
great, but they won’t turn into cost
savings unless you have the right plan.
Define technical steps and targets for
everyone involved in the initiative.
5) Implement Goals – While this may
sound simple, using your action plan
correctly can be the difference between
a cost-saving project and a failed one.
Make sure to monitor results throughout
the process to ensure optimal outcomes.
6) Evaluate Progress – Evaluations of
energy-saving projects should be performed regularly. During your review,
take a look at the achieved results compared to your action plan to help isolate
areas where the initiatives may have
7) Recognize Achievements – What good
is all that work if no one is aware of the
results? Provide both internal and external recognition after a goal is reached
to help boost morale and motivate employees to make even more sustainable
MANUFACTURERS from a variety of industries have used the ENERGY STAR certification program to
cut greenhouse gas emissions and reduce energy costs.
a second rotor on the existing turbine, the
researchers’ lab tests and computer simulations show that extra blades can increase
wind farm energy harvests by 18% – no
small figure given the maturity of wind
While the results are promising, more
research is needed to determine the best
way to incorporate the findings into turbine
production, such as the ideal placement for
the second rotor, its optimal size, and the
most useful type of airfoil.
With wind power adoption
continuing to grow, scientists
from Iowa State University have
developed a new design feature that could
allow turbines to harvest far more energy
than conventional systems.
The researchers point out the fact that
the large turbine blades disrupt the wind,
creating a wake that reduces the amount
of wind energy that can be harvested by
downstream turbines. These wind wakes
can cause a system to lose out on 8-40% of
its potential energy yield. By incorporating
Dual Rotor Improves Wind Turbine Efficiency
WIND TURBINES using the researchers’ dual-rotor design could vastly improve energy yield
in wind farms.
