Affordable Comfort Heads West
Bringing the gospel of residential energy efficiency
and quality construction to the West Coast, Affordable Comfort Inc. held
it's first regional conference in October. House technicians, researchers
and program developers descended on Pacific Gas and Electric Company's
Learning Center in San Ramon, California for three days of presentations,
workshops, and field tutorials.
One track of workshops, called "Survival
in the 90s," covered issues ranging from the effects of regulatory
and policy changes on energy efficiency to market transformation. Other
session categories included health and safety, energy-efficient construction,
ducts/HVAC systems, and multifamily buildings. Building construction, HVAC
and insulation contractors explored issues like marketing efficiency and
quality to customers, using diagnostic equipment, and guaranteeing cost
and comfort in new construction.
A recurring theme was that one can't treat part
of a house without understanding the whole. The complex relationships between
heating and cooling systems, ducts, holes in the building envelope, and
house pressures came up in session after session. One Saturday field tutorial
was a whole house audit (led by Rob de Kieffer of Sun Power Consumer Association,
Lydia Gill-Polley of Constructive Consulting, Inc., David Keefe of Building
Tune-Ups, Inc., and Eric Vander Leest of Chitwood Energy Management) designed
to stress the importance of having a complete picture of energy use in
a home. Other field tutorials covered testing for combustion safety, using
blower doors and other diagnostic equipment, mobile home insulation opportunities,
measuring duct leakage, and finding and sealing duct leaks.
A particularly enlightening presentation by John
Proctor of Proctor Engineering Group and Mark Modera of Lawrence Berkeley
Laboratory explained the links between air conditioner sizing, performance,
and efficiency. Modera and Proctor helped explain mysteries like why installing
a high-SEER air conditioner sometimes increases the peak energy
use in a house.
In addition to the opportunity to learn from
the "experts," the conference brought utility program planners,
energy auditors, researchers, consultants, builders, and contractors together.
Issues of air conditioner sizing and installation demonstrate the importance
of communication between contractors and utility program managers. Since
buyers usually do not know how to judge quality, air-conditioning contractors
often end up competing on price alone, which makes taking the time to do
quality work difficult if the company is to make a profit. Yet many utilities'
high-SEER air conditioner rebate programs are not designed to reward proper
sizing and installation, and do not require duct sealing before the unit
is installed. Of course, whether the utility is involved or not, contractors
have a role in educating customers about what a quality air conditioning
job entails, and many HVAC professionals shared stories of their successes
marketing quality instead of price.
The national Affordable Comfort conference will
be held in Pittsburg March 26-31. For details call Affordable Comfort,
