UPCOMING AFFORDABLE
COMFORT CONFERENCE
2004
If you havent done
so already, but
plan on attending,
you need to
register for the
Affordable Comfort Conference
(ACC) 2004 which will be
happening from April 26
th
- May 1
st
,
2004. This years conference is
being held in Minneapolis,
Minnesota.
Again this year, there are many
sessions that are targeted to the
weatherization professional.
Individual Tracks (of 3, 5, or 8
sessions) covering Fundamen-
tals, Heating and Hot Water,
Health and Safety, Consumer
Education, and Tools and
Techniques will provide updated
knowledge for you to bring back
and implement into your local
program.

ELECTRIC BASELOAD FOR
HWAP
Overwhelmingly across the state
of Ohio, electric baseload
measures are being ignored by
grantees receiving HWAP funds.
These opportunities are valuable
electrical efficiency improve-
ments that, when utilized in
conjunction with client education,
can be a great way to further
energy cost savings for the
HWAP customer.
With newer technology in
compact fluorescent light bulbs,
replacing high wattage
incandescent bulbs with lower
wattage compact fluorescent
bulbs has provided adequate
lighting without compromising
luminance levels at the working
surface.
Refrigerators can also be
replaced in an effort to reduce the
electric consumption in HWAP
homes. The costs involved with
replacing light bulbs and/or
refrigerators are allowable
provided they are cost justified
using metering devices and
transferring the results to the
charts in the Weatherization
Program Standards (WPS) or a
NEAT audit. The bulbs and
appliances to be replaced can be
metered to determine their
annual usage. If the cost to
replace the devices meet the
criteria in the WPS, then
grantees can purchase and
install them for their customers.
The Building Weatherization
Report (BWR) has a category for
Baseload and those costs are
entered there.

Local electric service providers
pricing per kilowatt-hour is an
important factor in determining if
the base load measure will be
cost effective.
The Ohio Office of Energy
Efficiency (OEE) will be looking
for base load opportunities during
HWAP monitoring visits to
ensure that the customers of
Ohio benefit from all meaningful
energy saving measures. The
inclusion of base load measures
into the customer s home
provides greater savings
potential when used in
conjunction with weatherization
retrofits.
ELECTRIC PARTNERSHIP
PROGRAM (EPP)
EVALUATION
The OEE has received the final
report for the first year of the
Ohio EPP Process Evaluation,
conducted by APPRISE,
Incorporated. The EPP aims to
reduce electric energy
consumption of Percentage of
Income Payment Plan (PIPP)
households, and reduce the
growth of PIPP customers
arrearages and the USF rider. To
accomplish this objective, the
EPP provides energy services
that vary with the customers
usage level. The program
installs cost-effective energy
conservation measures and
provides education to help
customers understand the
program, to improve measure
performance, and to take
energy-saving actions.
The following is a brief
description of the findings and
recommendations from the first
year of the Process Evaluation
of the EPP.
Significant improvements have
been made in the design and
implementation of the EPP
during the second year of
operation.
Some of the key accomplish-
ments have been:
Providers have adapted to
the software, technology, and
other new requirements of
EPP.
Data through the first quarter
of 2003 shows that
approximately 5,000 high use
households and 500
moderate use households
have been served.
Enhancements and fixes to
the software have greatly
improved the operation of
data collection and reporting
system.
A survey of program
recipients revealed high
levels of client satisfaction
and increased adherence to
education and audit
procedures by the providers.
Additional components have
been added to the program
design, and have been
implemented by some of the
providers.
New policies were
established as part of the
second Request for
Proposals (RFP) from
providers, and the RFP for
providers was successfully
implemented.
Recommendations for
continued improvements to
the program include:
additional training, enhanced
quality control, improved
documentation of program
procedures, continued
upgrading of the software,
and continued technical and
programmatic support for
the providers from OEE.
Evaluation continues on both
the impact and process of
the EPP.
AIR LEAKAGE WHERES
THE PROBLEM AND
WHATS THE PROBLEM ???
Almost everybody in Ohio
knows what the OVERALLS
scale is (O</b>hio V</b>ariable E</b>nd
R</b>esults A</b>ir L</b>eakage L</b>evel
S</b>cale) and what it means.
Currently, it is the yardstick by
which successful air leakage
reduction on weatherized homes
in Ohio is measured. Does
meeting the OVERALLS target
reduction guarantee that the
finished house is not drafty?
Read on
To calculate an OVERALLS
number for a particular home, a
PRE blower door reading is
taken. This number is located on
the OVERALLS scale, in order
to determine the target POST
blower door reading (based on
the reduction percentage noted
on the chart).
Look at the following examples:
PRE blower OVERALLS OVERALLS
door #
% reduction
target #
4,000 CFM50 30% 2,800 CFM50
5,000 CFM50 40% 3,000 CFM50
6,000 CFM50 45% 3,300 CFM50
7,500 CFM50 50% 3,750 CFM50
What do these examples show?
They confirm that even though
the OVERALLS target reduction
number is achieved, in most
cases, a leaky home still exists.

(continued on page 4)
How do Ohios HWAP
providers stack-up against
the OVERALLS scale?
A review of the PY02 completed
units show that 33 of the 58 Ohio
HWAP providers failed to meet
the applicable OVERALLS target
reduction on at least half of the
homes they weatherized
(minimum 2,750 CFM50 PRE
blower door number).
Statewide in PY02, a total of
1,842 homes failed to achieve
their OVERALLS target
reduction (28% of all homes
weatherized).
The trend seems to be continuing
in PY03. A review of the homes
weatherized in the first six
months of this program year
produced similar results.
Statewide, 908 homes did not
reach their OVERALLS target
reduction.
What is especially troubling
about these findings is that many
of the HWAP providers utilize
multiple funding sources in their
weatherization efforts. These
additional monies should
translate into a more thorough
job being done, i.e., OVERALLS
being surpassed. This does not
appear to be the case, however.
Why is reducing air leakage
important?
While having some air
exchanges in a home is
desirable to maintain indoor air
quality, excessive air leakage
can:
cost energy dollars (air
infiltration can account for 30%
or more of a homes heating and
cooling costs);
contribute to moisture
migration and building
degradation; and
cause client discomfort.
H
ow is unwanted air leakage
located?
Locating leakage sites begins
with properly defining the building
envelope, in other words,
establishing the pressure and
thermal boundaries. In most
cases, this will include the
basement, and possibly the
crawl space. Although they can
be a significant source of
unwanted leakage, thorough air
sealing of these two areas is
often overlooked. After the
buildings zones are defined
(slopes dense-packed, side-
walls dense-packed, obvious by-
passes sealed, etc.), zone
testing of these areas should
take place, ensuring a maximum
200 CFM50 leakage into the
conditioned parts of the home.
Allowances should be made for
leakage from atmospheric
appliance venting. Some other
suggestions to locate unwanted
air leakage include:
!
Cut-in attic / kneewall venting
before doing blower door testing
In some cases, unvented or
under-ventilated attics can lead
to misleading zone test results.
This is due to the exterior barrier
being very air-tight.
Consequently, any venting
should be cut-in at the beginning
of the job.
!
Address fairly common
leakage sites
Visual inspection should turn up
one or more of the following
common leakage sites:
kneewall floor joist cavities
open-top partition walls
around plumbing vents (stink
pipes), plumbing chases,
and chimney chases
penetrations in the bandjoist
dropped ceilings or soffits
!
Open the door a crack, to
identify leaky rooms
To get an idea as to which rooms
are the leaky ones, with the
blower door running at 50Pa,
close the interior doors one by
one, all but a crack. Feel the blast
of air coming past it; if its a lot,
youve found a leaky room; if its
not, try the next one.
