HomeMy WebLinkAboutAgenda Report - May 3, 2000 E-17AGENDA TITLE: Public Benefits Program Grant — Zion Reformed Church and Middle School Demand-side
Management Project ($16,190.25)
MEETING DATE: May 3, 2000
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council approve a Public Benefits Program Grant in the amount
of $16,190.25 for a demand-side management project at Zion Reformed
Church and Middle School, located at 105 S. Ham Lane.
BACKGROUND INFORMATION: Zion Reformed Church will be installing new, high efficiency air conditioning
units for the sanctuary, as well as classroom facilities. With the assistance of
their chosen air conditioning contractor, and the City of Lodi Electric Utility,
representatives of Zion Reformed Church and Middle School have elected to install those units deemed as energy
efficient, thus qualifying the organization for the standard 25% Public Benefits Program contribution. Specifically, Zion
Reformed Church will install:
➢ one (1) 25 -ton high efficiency Bryant Commercial Air -Cooled Condensing Unit, Model 576H;
➢ related air supply system, programmable thermostat and other related materials;
➢ for the classrooms - four (4) 5 -ton high efficiency Bryant Single -Package Electric Cooling
Units (with gas-fired heat component), and one (1) 3 -ton high efficiency Bryant Single -
Package Electric Cooling Unit (with gas-fired heating), Model 583A; all five units are rated at
a 12.0 Seasonal Energy Efficiency Rating; and
➢ in the classrooms - installing appropriate air delivery system and programmable thermostats
for each classroom for individual control.
Attached please find supporting documentation pertaining to the energy efficient equipment, as well as the letter of
request from Zion Reformed Church and Middle School.
The high efficiency air conditioning units, based upon industry rated standards, utilize approximately 10 percent less
electricity than lower rated units. By installing higher efficiency or more energy efficient equipment, assists this
customer in reducing monthly utility costs, as well as operations and maintenance costs (the latter based assumption
is based on the fact that new, highly efficient equipment is being installed, which requires less maintenance by the
owner).
Following numerous discussions with representatives of Zion Reformed Church, and their selected equipment
installer, the City of Lodi Electric Utility respectfully recommends approval of this funding request as a qualifying
component of the Public Benefits Program.

Dear Alan,
Zion Reformed Church and Middle School is requesting $16,190.25 from the City of Lodi's
Public Public Benefits Program grant fund. This will be utilized for the purchase and installation
of five high efficiency air conditioning units for our expanding middle school and one unit for our
sanctuary.
Zion Reformed Church has been a fixture in the community for the last 57 years, fifty years of
which have spent at our present location on Hain Lane. In 1996, the congregation of over 400
hundred members felt there was a need for an additional choice in Middle School Education and
opened Zion Middle School. What began as a hope and dream for twenty students has grown to
a reality of 83 students and an enormous waiting list. Our hopes are that we will continue to
grow and expand. This is consistent with the vision statement of the church which incorporates
the concept of reaching out into our community and being servants to those who reside in it.
However, with facilities that either rely on window mounted air conditioning units or have no air
conditioning system at all, we feel that we can not move forward until we bring our facilities up
to a higher standard of comfort and provide an environment that is conducive to learning.
This past Sunday, April 9, 2000, I was ordained and installed as the senior pastor here at Zion.
It is certainly my hope that we will continue to reach out to the Lodi community and be of
service to them. Our church looks forward to working with the city on this project and
appreciates your efforts and consideration of our request. If there is anything more that I can do
or questions that I may answer, please feel free to contact me.
Sincerely
Matthew W. Duerr

• Direct Spark Ignition
• Low Sound Levels
• Up to 81 % AFUE
• 12 SEER
FEATURE/BENEFITS
One-piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
EASY INSTALLATION — Factory -assembled package is a
compact, fully self-contained, combination gas heatingtelectric
cooling unit that is pre -wired, pre -piped, and pre -charged for
minimum installation expense.
These units are available in a variety of standard and optional
heating/cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are light-
weight and install easily on a rooftop or at ground level. The
high tech composite basepan eliminates rust problems associ-
ated with ground level applications.
CONVERTIBLE DUCT CONFIGURATION — Unit is designed
for easy use in either downflow or horizontal applications. Each
unit is easily converted from horizontal to downflow with addition
of two accessory duct covers.
EFFICIENT OPERATION
High -Efficiency Design with SEER (Seasonal Energy Effi-
ciency Ratios) of 12.0 and AFUE (Annual Fuel Utilization Effi-
ciency) rating as high as 81%.
Energy -Saving, Direct Spark Ignition saves gas by operating
only when the room thermostat calls for heating. Standard units
are furnished with natural gas controls. A low cost field -installed
kit for propane conversion is available for all units.
All Units meet the California maximum oxides of nitrogen
(NOx) emission requirements when accessory kit is used.
DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for high efficiency. Each compres-
sor is hermetically sealed against contamination to help pro-
mote longer life and dependable operation. Each compressor
also has vibration isolation to provide quieter operation. All
compressors have internal high pressure and overcurrent
protection.
Monoport Inshot Burners produce precise air -togas mixture,
which provides for dean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if
ever, requires cleaning. All gas furnace components are acces-
sible in one compartment.
Turbo-tubularTm Heat Exchangers are constructed of alumi-
nized steel for corrosion resistance and optimum heat transfer
for improved efficiency. The tubular design permits hot gases to
make multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force
the hot gases to stay in close contact with the walls, improving
heat transfer.
Direct -Drive Mufti -Speed, PSC (Permanent Split Capacitor)
Blower Motor is standard on all 583A models.
Direct -Drive, PSC Condenser -Fan Motors are designed to
help reduce energy consumption and provide for cooling opera-
tion down to 40 F outdoor temperature. Motormaster® I I low am-
bient kit is available as a field -installed accessory.
Corporate Thermostats include the Time Guard® II anti -short
cycle protection circuitry. If an Original Equipment Manufacture
(OEM) thermostat is used the Time Guard II field -installed anti -
short cycle kit must be used.
Refrigerant System is designed to provide dependability. Liq-
uid refrigerant strainers are used to promote clean, unrestricted
operation. Each unit leaves the factory with a full refrigerant
charge. Refrigerant service connections make checking operat-
ing pressures easier.
Evaporator and Condenser Coils are computer -designed for
optimum heat transfer and cooling efficiency. The evaporator
coil is fabricated from copper tube and aluminum fins and is lo-
cated inside the unit for protection against damage. The con-
denser coil is internally mounted on the top tier of the unit. A
FIOP (Factory -Installed Option) metal louvered grille is available
on all models. Copper fin coils and pre -coated fin coils are avail-
able from the factory by special order. These coils are recom-
mended in applications where aluminum fins are likely to be
damaged due to corrosion. They are ideal for seacoast
applications.
Low Sound Ratings ensure a quiet indoor and outdoor envi-
ronment with sound ratings as low as 7.2 bels. (See page 3.)
Easy to Service Cabinets provide easy single -panel accessi-
bility to serviceable components during maintenance and instal-
lation. The basepan with integrated drain pan provides easy
ground level installation with or without a mounting pad. Conve-
nient handholds are provided to manipulate the unit on the
Form No. PDS 583A.24.1
jobsite. A nesting feature ensures a positive basepan to roof
curb seal when the unit is roof mounted. A convenient 3/4 -in.
wide perimeter flange makes frame mounting on a rooftop easy.
Downflow Operation is easily provided In the field to allow ver-
tical ductwork connections. The basepan utilizes knockout style
seals on the bottom openings to ensure a positive seal in the
horizontal airflow mode.
Integrated Gas Control (IGC) Board provides safe and effi-
cient control of heating and simplifies troubleshooting through
its built-in diagnostic function.
Cabinets are constructed of heavy-duty, phosphated, zinc-, -
coated prepainted steel capable of withstanding SW hours in
salt spray. Interior surfaces of the evaporator/beat exchanger
compartment are insulated with cleanable semi-rigid insulation
board, which keeps the conditioned air from being affected by
the outdoor ambient temperature and provides improved indoor
air quality. (Conforms to American Society of Heating, Refrig-
eration and Air Conditioning Engineers No. 62P.) The sloped
drain pan minimizes standing water in the pan.

CONTROLS
OPERATING SEQUENCE
Heating — When the thermostat calls for heating, terminal "W"
is energized, starting the induced -draft motor. When the hall -
effect sensor on the induced -draft motor senses that it has
reached the required speed, the bumer ignition sequence be-
gins. The indoor (evaporator) fan motor (IFM) is energized
45 seconds after flame is established. When the thermostat is
satisfied and "W" is deenergized, the IFM stops after a
45 -second time -off delay.
Cooling — When the system thermostat calls for cooling, 24 V
is supplied to the "Y" and "G" terminals of the thermostat. This
completes the circuit to the contactor coil (C) and indoor (evapo-
rator) fan relay (IFR). The normally open contacts of C dose
and complete the circuit through compressor motor (COMP) to
24
—
outdoor (condenser) fan motor (OFM). Both motors start in-
stantly. The set of normally open contacts of IFR close and com-
plete the circuit through IFM. The IFM starts instantly.
On the loss of the thermostat call for cooling, 24 v is removed
.from both the "Y" and "G" terminals (provided the fan switch is
in the "AUTO" position) deenergizing the compressor contactor
and opening the contacts supplying power to compressor/OFM.
After a 30 -second delay, the I FM shuts off. If the thermostat
fan selector switch in is the "ON" position, the IFM will run
conti'n'uously.
NOTE: On units with a Time Guard® II device: once the com-
pressor has started and then stopped, it cannot be restarted
again until 5 minutes have elapsed.
