  Nextek Power Systems: Technology You Can Bank On

DETROIT -- January 7, 2013

When PNC Financial decided to push farther than the LEED (Leadership in Energy
and Environmental Design) Platinum certification for their model net-zero
energy branch in Fort Lauderdale, the goal was high: 50% energy savings and
the same or better comfort for staff and customers as compared to PNC’s 2500+
branches.

Thanks to solar panels on the roof and walkways, the building actually
generates more electricity than it uses, sending the surplus to the grid.
Sending excess power back to the grid is possible thanks to careful design and
planning the company carried out with its architect, Gensler and green
building consultants CJL Engineering and Paladino & Company.

PNC Financial specified a direct current (dc) power system from Nextek Power
Systems to significantly increase the efficiency of their lighting system and
its use of renewable energy generated at the building site. Nextek’s
innovative Direct Coupling^® platform eliminates wasteful power conversions
inherent in conventional systems. "This is another example of PNC's commitment
to innovation and energy efficiency," said Gary Saulson , PNC's director of
Corporate Real Estate. "We expect the net-zero energy branch to spur business
growth and development in the area. Ultimately, we hope it will inspire other
businesses to adopt similar green building practices."

Most of the lighting in this PNC Bank branch is connected to the Nextek
patented dc microgrid that uses the solar power before it gets converted into
grid-compatible ac power. This allows the power generated at the site to be
used avoiding two conversions: one from dc (solar) to ac (the grid), as well
as from ac (the grid) back to dc (the electronic light fixture) amounting to a
large integrated efficiency improvement. When the sun’s not shining, the dc
microgrid powers itself by converting the grid power into dc at higher
efficiency than any single device can accomplish affordably on its own. For
more, see the video AC or DC Power?

Nextek CEO Paul Savage says PNC Financial’s use of dc microgrid technology
represents a growing trend in net-zero energy building design. “In today’s
competitive marketplace it is not enough to install solar panels on the roof
and put a plaque on the door announcing you’re sustainable. Thoughtful design
that reduces the building’s power requirement first is what’s needed, and
that’s what PNC is doing.” By connecting the clean dc power generated by the
sun to dc consuming lighting inside the building, and adding daylight
harvesting and other control strategies, the branch’s lighting will consume
70% less power from the grid.
