accreditation body, has not yet certified any building-integrated turbines. The organization verifies energy output,
rated power, sound level, durability, and safety according to
industry standards set by the American Wind Energy Association. The good news is that several VAWT models have
pending applications, showing promise that the technology
is edging forward.
If a traditional wind turbine is out of the question, vertical axis models remain your next best option to turn a stiff
breeze into renewable energy. Their installation flexibility
and small profile can adapt to urban locations where real
estate is tight but wind is plentiful. B

says Schneider. These contracts allow property managers
to avoid buying a turbine outright and simply pay for the
electricity it generates.
Also ask your utility about net metering, an option that
gives your facility credits when you have excess clean energy you can put back onto the grid. Otherwise any power you
can use will go to waste or you’ll pay an avoided rate that
eats into your ROI. Not every provider allows this type of
arrangement, notes Gilchrist, and you may need to upgrade
your connections to enable this functionality.
So is a vertical axis turbine a match for your facility? As
performance data can be hard to verify given the limited
amount of commercial applications, risk-averse FMs may
not feel comfortable with this option. It’s worth noting
that the Small Wind Certification Council, an independent
In Long Island City, Queens, three vertical-axis turbines grace the top of the Pearson Square Court apartment building. Installed in May 2014 and projected to generate 9. 6 k Wh, the turbines
produce power that offsets the common areas in the building,
including the lobby, hallways, gym, and roof lounge.
At the 388 Bridge Street apartment complex in downtown
Brooklyn, two turbines can be seen spinning atop the building
from the Long Island Expressway and surrounding streets.

Before these installations were set in motion, UGE conducted a
site analysis to evaluate which renewable energy solutions would
generate the optimal amount of electricity. The turbines’ helical
structure was determined to be well suited to extract energy from
winds in urban settings, which tend to come from many directions.
Both projects have unobstructed locations for the turbines to gain
