Green Builder Chooses
Mini-Splits for Whole-House HVAC
One
of the “greenest” home builders in North Carolina, a firm widely
recognized for green innovation and commitment to environmental
sustainability, has taken their commitment to high efficiency HVAC to a
new level.
Anne & Bradshaw General
Contractors, Inc., based in Wrightsville Beach, NC, a suburb of
Wilmington
in an area known as Cape Fear, chose “green build” as their strategic
path several years ago. “We’ve never regretted the move,” said Pamela Fasse,
general contractor and partner in the firm. “I’ve considered myself an
environmental builder for many years, with a focus on energy efficiency
and sustainability, but went all-out ‘green’ about four years ago.
It appears that we were green before green was in style."
“We feel it’s important to stay current with conservation techniques to
minimize cost without sacrificing comfort,” added Fasse. “There’s a
level of global responsibility at work, but we force ourselves to think
locally. After all, as a home builder, we’re apprised of new techniques
and technology before consumers are, and it’s right here at home where
we can have the greatest impact. Going a bit more broadly, green
construction aids in the preservation of our state’s fragile coastal
ecosystems,” says Fasse and her partner/husband, Brad Karl.
One of the
key contributors to Anne & Bradshaw’s green-build approach has been the
recent addition of ductless mini split air conditioning and heat pump
systems. “My husband and I were traveling in Asia last year; we were
amazed at the simplicity and efficiency of the systems, and how they
were used everywhere” said Fasse. “Even at higher elevations in Japan,
where it gets quite cold,
mini-splits were meeting the comfort needs of
what seemed to be every home and business.”
Fasse
returned from her trip and looked into the availability of ductless
systems here. “We did a lot of research after that trip,” added Fasse.
“What we found initially was that in this area there was very little
experience with or knowledge about mini split systems except on a
one-room scale.”
When Craig
Chadwick, owner of the independent rep firm, Chadwick & Associates,
Greensboro,
NC, learned through Wilmington’s Four Seasons Heating and Air
Conditioning that Pam had interest in knowing more about the systems, he
traveled there quickly. Within a few months, North Carolina’s
first whole-house ductless mini-split application was under way.
“Chadwick
was the critical link for us,” she added. “They had expertise on
tap and the advantage of their many years in the market. They gave
us a balanced view of how best to apply the technology; they did Manual
J load calculations . . . the works. My husband and I settled on
equipment manufactured by Fujitsu, a product line through Chadwick that
exceeded our expectations. We were especially impressed with the
manufacturer’s variable-speed Halcyon line.”
They’ve now
installed several Fujitsu split systems in homes they’ve built with the
help of Walt Rager and Jamie Fowler of Four Seasons HVAC, and Don Lewis,
owner of All Pro Services, an HVAC firm also based in Wilmington.
Lewis
eagerly promotes the
Halcyon line’s
ultra-high efficiency – with ratings of up to 21 SEER and 10.0 HSPF –
quiet, reliable operation and sleek design. The Halcyon line now
includes 29 air conditioning and heat pump systems with capacity ranges
of 9,000 to 42,000 BTUs, many also offering sophisticated Indoor Air
Quality (I.A.Q.) plasma air filtration.
“The systems are
ideal for heating and cooling, and they’re a great match to Anne &
Bradshaw’s green-build emphasis,” said Lewis. “Mix-and-match
evaporators allow me to create the perfect climate control for any size
space.”
Standard features
include wireless remote control, plasma filter, sleep timer, 24-hour
timer, dry mode, auto louver, auto mode, quiet mode, auto restart/reset,
auto changeover and efficient operation with low, or high ambient
temperatures. These models feature coil dry mode to help inhibit mold
and bacteria growth by reversing the cycle of refrigerant to dry out
condensation in the indoor coil without changing room temperature.
During dry coil mode the plasma filter operates to help disinfect the
coil. This feature is helpful in businesses where a system is shut off
for the weekend or a vacation home that may be shut down for the
season.
Fasse adds
that it can cost up to 10 percent more to build a green home than it
does a conventional one. But, ultimately, it costs less to live in them
because of their greater energy efficiency and easier maintenance.
Fasse said
the average monthly cost of electricity in her Parade home has been
about $50, versus $200 in a conventional home. “Our homeowners are
delighted with the technology and so are we. We’ve
now added a key new ingredient to our green home recipe.”
