TRENDS
Conference Christens
Home Performance Industry
The Affordable Comfort West conference came to California
for the second time on October 11-13, 1995. Participants represented heating,
ventilation, and air conditioning (HVAC) and other contractors; consulting
firms; utilities; and nonprofit organizations. Presenters spoke about the
responsibility to understand the interactions among energy, safety, and
comfort in a home, and described many successful contractors who are expanding
their services and taking a comprehensive view of how the house functions
as a system. This approach has come to be known as home performance, and
we are sure to hear more about it.
The day before regular sessions began, seasoned
trainers and field practitioners offered hands-on short courses, both in
the field and in the classroom. They gave participants practical experience
with energy- and safety-related topics: inspecting gas heating systems;
measuring heat pump performance and duct leakage; sizing, selecting, and
air-balancing HVAC systems; understanding indoor air quality and mechanical
ventilation; determining house boundaries with pressure diagnostics; and
educating customers.
Especially popular at this year's Affordable Comfort
West conference, hands-on "short courses" both in the field and in classrooms
offered participants a variety of learning opportunities. |
A construction site tour (led by Gary Klein of the
California Energy Commission, Gary Nelson of the Energy Conservatory, and
Lance Pustin, a weatherization field trainer from Minneapolis) gave participants
a look at where problems occur in tract homes and showed them how to diagnose
these problems with equipment such as the blower door, infrared scanner,
pressure pan, Duct Blaster, flow hood, and digital pressure gauge. The
group performed diagnostic tests on a completed new home and then visited
a house being constructed to the same plan to see what it looked like behind
the gypsum board. In a particularly enlightening demonstration, the trainers
sealed off the registers and blew smoke into the duct system, which was
entirely visible at the second site. The participants (and the duct installation
crew, who were working nearby) saw the smoke pour out of leaky connections,
plenums, and even the air handler.
At the opening plenary, Affordable Comfort Incorporated's
president, Gregory Thomas, dropped the big news: the birth of the Affordable
Comfort Housing Performance Association. The goal of this new organization
is to create a long-term, consumer-driven market for high-quality home
performance services. Thomas defines these as services that increase the
comfort, health and safety, efficiency, and durability of housing by treating
the house as a whole system. The main focus of the organization will be
to educate the general public and policymakers on housing performance issues
and to provide housing performance contractors with marketing information
and support.
Dominic Guarino, editor-in-chief of Contracting
Business magazine, also announced the formation of a new nonprofit
organization, the National Comfort Foundation, which will focus on teaching
homeowners; builders; and HVAC contractors, distributors, and manufacturers
what to look for in an HVAC system. Guarino hopes to create a willingness
among customers to pay for quality because they understand what's involved,
and to provide contractors with the resources they need to compete on quality
instead of price.
The conference continued at a furious pace for
the next two days, with 54 workshops in nine tracks. Presenters covered
topics ranging from the technical aspects of energy conservation (like
sizing cooling systems, advances in duct-sealing techniques, and designing
lighting systems) to issues of liability, customer education, sales, and
program financing.
An evening panel provided a lively discussion
of carbon monoxide issues. While panelists differed sharply on the extent
to which CO poses a health problem, by the end all parties agreed on a
few points. The main unresolved issues include what level of carbon monoxide
is dangerous; over what length of time a flue gas reversal (backdraft)
is unacceptable; what method should be used to measure CO from kitchen
ranges; and under what operating condition houses should be tested for
backdrafting potential (for instance, the worst-case condition or a condition
that is likely to occur under normal operation of the house). The panel
reached a consensus that standard testing protocols need to be developed
and that, in the meantime, testing should be done in a consistent manner
for each house in a given program.
One of the goals of Affordable Comfort is to
"expand the traditional boundaries of the various building trades, in order
to create a housing industry capable of providing quality improvements
to whole house systems." Although each participant got something different
out of the conference, it certainly served to expand boundaries and expose
attendees to new ways of looking at house performance.
We can expect an even larger contingent of participants
and trainers at the continental Affordable Comfort conference, to be held
March 17-22 in Chicago. For more information about the upcoming conference,
