HomeMy WebLinkAboutAgenda Report - June 7, 2000 E-16AGENDA TITLE: Public Benefits Program Grant — United Congregational Church Demand-side Management
Project ($75,769.75)
MEETING DATE: June 7, 2000
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council approve a Public Benefits Program grant in the amount
of $75,769.75 for a demand-side management project at United
Congregational Church.
BACKGROUND INFORMATION: United Congregational Church (located on the corner of Hutchins Street and
Tokay Street) has embarked upon a multi -faceted energy efficiency and
equipment improvement project. Specifically, United Congregational Church
will be installing and/or retrofitting the following items within their facility:
➢ removing a number of inefficient HVAC (heating & cooling) units on the classroom area of the church property,
and installing new, highly efficient HVAC heat pump units;
➢ retrofitting all existing classroom, office space and sanctuary lighting with state-of-the-art fluorescent lighting and
associated controls;
➢ installing a new, 15 -ton energy efficient air cooled chiller (air conditioning system) for the sanctuary;
➢ replacing the existing boiler, with a new, highly efficient piece of equipment that will compliment the
aforementioned 15 -ton chiller;
➢ installing a new automated control logic system (often referred to as an energy management system), designed to
allow church personnel the ability to remotely schedule (turn on/off) and operate the facilities HVAC system.
Attached for Council review is a copy of the comprehensive engineered energy analysis compiled by the City of Lodi
Electric Utility and the city's energy services partner, Energy Masters International. The report, which has been
presented to representatives of United Congregational Church, further outlines the energy efficiency and equipment
improvement projects currently proposed, as well as other pertinent information regarding this effort.
The Public Benefits Program grant in the amount of $75,769.75 reflects a 25% energy efficiency incentive rebate for
the total cost of the project to United Congregational Church. The 25% rebate is consistent with all other rebates
offered to commercial and industrial electric utility customers throughout Lodi that participate in the City of Lodi Energy
Services Partnership Program (which is an element of the City of Lodi Public Benefits Program).

EXECUTIVE SUMMARY
a
Fnr• !fi N,:f f, L,o 40SPbUtcd without prier written Energy Masters approval.
Energy Masters International is pleased to submit this final report outlining a
Comprehensive Energy Management and Facilities Upgrade Plan for the United
Congregational Christian Church (UCCC). In this document we describe what we can
accomplish and present a detailed cost -to -savings ratio analysis. This report is the
result of extensive on-site study and technical analyses, and is reflective of our desire to
deliver the most cost effective, state-of-the-art and reliable energy and operational
savings solutions possible.
With over twenty years in the energy efficiency services and performance contracting
industry, Energy Masters possesses a long history of successful energy partnerships.
Our vendor independent approach assures that the UCCC will receive the most
objective and cost-effective program possible. We are a subsidiary of Northern States
Power Company (NSP), an investor owned utility providing electricity and natural gas,
with annual revenues in excess of $2.5 billion and assets exceeding $6.2 billion. This
alliance, along with our vast experience in energy services and objective approach to
energy retrofit practices, will provide the church with a package of services
unsurpassed.
This CEA was conducted in the following seven steps:
An on-site visit to each building to conduct a detailed survey of the:
• facility operating procedures and schedules;
• construction details including type and condition of doors and windows;
• heating, ventilating and air conditioning (HVAC) equipment to determine
capacity, operation and condition, including operational measurements where
pertinent and practical;
• entire lighting system, space by space, recording type and condition of
fixtures, operation and typical light levels;
• all other specified energy consuming equipment or procedures; and
• review of each building's architectural, mechanical and electrical drawings.
2. Building heating, cooling and ventilation requirements were calculated to verify
whether the existing equipment is properly sized.
3. Analysis of one year of utility data to identify historical changes and to establish an
energy baseline which will be used as the beginning reference point.
4. Identification, development and analysis of all potential energy saving
improvements. These analyses were accomplished through hand calculated
engineering procedures.
5. Determination of firm costs for the design, installation and project management of
each energy saving measure.
6. Preparation and presentation of the detailed CEA report to the UCCC.

FACILITY PROFILE
',�,,A'. xaiwpeitvo! Ene,i;y Masters inr(,,nvionaf Not to be reproduced o+ distributed without prior writter, Energy Masters approvat.
Facility Profile
The facility consists of (2) buildings; the sanctuary and classroomffellowship hall
structure. The buildings were originally constructed in the 195Us.
The sanctuary consists of a main assembly (pews), a foyer, office, side rooms,
and sacristy. A high vaulted ceiling covers the sacristy and the main assembly.
The offices and foyer have a low ceiling/flat roof. The sanctuary is approximately
7,800 ft2 in total area; the assembly/sacristy account for 4,800 ft2 .
The classroom building is divided into (10) classrooms, a fellowship hall (roughly
the size of four classrooms), a storage area, an office, and a central basement
mechanical/electrical room. The building has a saw tooth roof design and is
connected to the sanctuary by covered walkways. The total building area is
approximately 5,940 W.
"iif1, i'rr
The sanctuary provides a house of worship for an average of 150 parishioners
every Sunday from 10-11 am. Special events are rare; occasional concerts and
conferences occur only 4 to 5 times a year. Choir practice is held in the
sanctuary on Wednesday evenings. The main office is usually occupied during
the day.
The classrooms house 30-40 students and teachers (Headstart Program) all year
round. The congregation utilizes the fellowship hall for dinners and gatherings of
up to 100 people. The nursery and Plymouth rooms are used on Sundays and
for special events. The fellowship hall is sometimes used as a polling station and
is home once a month to the quitters guild.

The existing lighting system is dated T-12 fluorescent and incandescent
technology and has not been retrofitted to incorporate current energy efficient
lighting measures such as new state-of-the-art electronic ballasts, T-8 and
compact fluorescent lamps. A lighting retrofitteonversion throughout the buildings
would improve energy efficiency, enhance lighting levels, and reduce
maintenance costs. With the additional installation of motion sensors in selected
areas such as the offices and classrooms, there would be added energy
efficiency savings simply by saving the time associated with lights being left on in
rooms that are not being occupied and control of the lighting system during non-
business hours. Occupancy sensors will also eliminate manual operation and
increase lamp life.
The conversion of these fixtures represents an excellent means to reduce energy
costs, while concurrently increasing the quality of the light produced by the
fixtures. Not only are these systems more energy efficient, but they produce light
that creates a more natural, color -corrected learning, worshiping and working
environment.
The central plant's natural gas-fired boiler heats the sanctuary. A closed loop hot
water (hydronic) system supplies the (2) vertical air handler's hot water coils.
Note: The existing hot water supply line has failed and needs replacement.
The air handlers are housed in mechanical closets on each side of the sanctuary.
They provide warm air via an underground duct system to floor mounted grilles
located along the length of the building. A 3 -way control valve modulates to
maintain space temperature and provide constant water flow through the system.
The air handler fans are controlled by a twist timer and are manually operated on
an as -needed basis.
The central plant heats the classrooms and fellowship hall as well. Each space
has a ceiling suspended unit ventilator which provides warm air to the space.
Separate packaged rooftop HVAC units provide the cooling. The (6) units provide
cool air to the space via individual rooftop ductwork systems. Room thermostats
manually control both heating and cooling.
The central mechanical plant consists of (1) a natural gas fired boiler and (2) re-
circulating pumps for the hydronic system. The original design for the plant
allowed for the future addition of cooling equipment. This type of system, known
as a Dual Temperature Water 2 -pipe system, is capable of providing either hot or
cold water to the air handling systems in the classrooms and sanctuary. This
system can be very effective, but is limited by its inability to provide simultaneous
heating and cooling and its lengthy, non -producing transition from one mode
(heating) to the other (cooling). Since the cooling equipment was never added to
the central plant, the sanctuary has no cooling.

TECHNICAL ANALYSIS & SCOPE OF WORK
.-,f Enrw, V rvlasles 1!rornationa! Not to be reproduced or distributed without prior written Energy Masters approval.
This section provides a description of the systems upgrades and energy savings
measures we recommend for each building. Please refer to "Section IV — Financial
Summary" for a summary of the costs and associated savings for each of the
program components.
Expressed Facility Needs
The church has expressed a desire to more fully utilize their sanctuary facilities. They
plan to add a second Sunday service in 2000. They would also like to attract more
use from community groups. However, the lack of air conditioning for the sanctuary
imposes a barrier to extended facility use. Outside groups will be reluctant to use the
facility during the summer months due to the lack of air conditioning. Congregational
use is inhibited as well. For example, the choir does not typically perform during the
summer because it is too hot where they are seated.
The controls for the environmental systems are also a concern. They are reported to
be too complicated for the staff to use effectively. Since controls are manual, the
potential exists for wasted energy by running equipment during unoccupied periods.
In addition, the central boilers as well as the rooftop HVAC units have reached their
useful life expectancy. Not only do they operate inefficiently, they will soon
experience abject failure, resulting in "emergency" need to replace conditions.
Emergency replacement of equipment is more costly and disruptive than planned
replacement. Waiting until equipment fails before replacing it also creates a "lost
opportunity"; system operational and efficiency improvements are not made because
no time is available to thoughtfully design an energy efficient replacement plan and
implement it.
As further analysis of the central plant boiler EMI and Air Systems performed a
pressure check of the existing hot water supply line to the Sanctuary and
found that the lines did not hold pressure, indicating that the lines had failed.

In addition, as part of this analysis, we performed an air balance on the existing
sanctuary air handling systems. We discovered that these systems are only moving
about 60% of their design airflow. We determined that the air supply restriction is due
to dirty coils.
Lighting & Lighting Control Retrofit
The lighting retrofit proposed below will offer many benefits to the church and
classroom facilities:
Reduced Energy Consumption
New T8 lamps and electronic ballasts
consume half the energy of the existing
T12 systems. Occupancy sensors turn
off unneeded lights when unoccupied
and control unneeded after-hours run
time.
Longer Life
New T8 lamps have a rated life span of
20,000 hours — double that of existing
T12 lamps.
Better Light Quantity and Quality
T-8 lamps produce the highest lumens
per watt and more natural color.
Lower Cooling Load Requirements
Air conditioning equipment run time
and energy consumption will be
reduced.
Trouble Free Warrantee Service
Energy Masters warrants fluorescent
fixtures and T-8 lamps for one year,
and electronic ballasts for five -years.
T12 Lamp and Ballast Disposal
The cost of lamp and ballast disposal is
included.
The Energy Conservation Measure (ECM) recommendations listed below will result
in improved light levels and energy savings in each space throughout the facilities.
ECM Title: Lighting Control Devices
Present Condition: The following locations can be retrofitted with lighting controls to
reduce electric energy consumption: Back Stage, Rear Office, Rest Rooms, Offices
and Classrooms 1-9.
Modification: Install motion, sound or infrared occupancy sensors in series with or in
place of the light control switch as follows:
16 - Wall mounted occupancy sensors
3 - Ceiling mounted occupancy motion sensors

ECM Title: Electronic Ballasts and T-8 Fluorescent Lamp Retrofit/Conversion
Existing lighting components include four foot and eight -foot fluorescent fixtures with
T-12 (4') 34 watt and (8') 123 watt fluorescent lamps. These lamps are driven by
standard magnetic ballasts, which, combined with the T-12 fluorescent lamps,
contribute to a highly inefficient lighting system.
ECM:
Installation of electronic ballasts and new energy saving 32 watt T-8 lamps will
reduce energy consumption and improve the current light level intensities. Electronic
ballasts are designed to operate lamps at lower wattage due to the higher frequency
provided to the lamps from the ballast. The electronic ballast also operates at a lower
temperature than conventional ballasts, which extends ballast life significantly and
lowers cooling load requirements.
Spaces to be retrofitted include the following:
• All Offices
• Sanctuary Soffet
• Classrooms
• Meeting Rooms
• Back Stage
• Rest Rooms
• Boiler Room
ECM Title: Compact Fluorescent Conversion
The existing Lobby, Mechanical Rooms, Display Case, Classroom, Rest Rooms,
Breeze Way and selected exterior fixtures currently use inefficient high wattage
incandescent lamps.
ECM:
The existing fixtures will be converted to high efficiency low wattage compact
fluorescent lamps with electronic ballasts.
ECM Title: Exit Lamp Retrofit
The existing exit signs use (2) 20 watt incandescent lamps. Exit lamps are normally
illuminated 24 hours per day or 8,760 hours per year and must be visible from a
specified distance in accordance with local fire codes.
The exit signs can be retrofitted with a 3 Watt LED (light emitting diode) lamp kit. The
kits contain all materials necessary to retrofit each existing exit fixture.

This lamp replacement will provide comparable light output while reducing energy
consumption and lamp maintenance. The average rated life of an incandescent lamp
is 2,000 hours compared to a rated life of 100,000 hours for the LED lamp kit. With
these lower wattage lamps, the fixture will also operate at a cooler temperature.
Spaces to be retrofitted include the following:
• All exit signs in all buildings
In summary, the proposed lighting system retrofits will offer these benefits:
✓ Reduced energy consumption and electrical costs
✓ Reduced maintenance and replacement costs
✓ Extended equipment life
✓ Enhanced lighting system performance
✓ More comfortable learning, worshiping and work environment.
✓ Warranteed, trouble free operation

costs in the project.
PCB Ballast Disposal
All existing PCB ballasts will be removed and properly disposed of in compliance with
appropriate laws and regulations. Disposal is included in project cost.
Mechanical System Improvements
In order to provide cost effective air conditioning for the sanctuary it is best to utilize
the existing hydronic (closed loop water) system. Since the original design allowed
for changing the system into dual water temperature operation, engineering analysis
was performed to best determine system modifications. It was determined that the
largest cooling unit that could be added to the existing system was a 15 ton air-
cooled chiller. This unit must be located outside. The area west of the boiler plant (in
the parking lot just in front of the metal sheds) appears to be the most practical
location. Hydronic system modifications to allow for the piping interconnections and
the addition of changeover control valves will also be required.
In order to improve the ability of the new system to adequately switch from seasonal
heating to cooling mode, the classroom heating system would be eliminated from the
hydronic loop. This will allow for more efficient operation of the chiller and boiler.
Since the modified system will have a smaller heating load, a smaller, more efficient
boiler will be installed to replace the existing boiler and the failed hot water supply
lines will be replaced.
Proper operation of this system will be required in order for the maximum cooling
needs to be sufficiently met. A worst case scenario might be an August afternoon
wedding with 200 plus people in attendance. Due to the inefficiencies inherent in
supplying cool air from floor grilles and the large latent heat load from people, a pre -
cooling mode of operation will be required. In fact, pre -cooling for all summer events
is highly recommended. Pre -cooling is done by starting the cooling systems 2-4
hours ahead of the anticipated event. In addition, the space temperature is set
slightly lower than usual, or than is required. Although the space may seem slightly
cool to the occupants when first entering, the space will quickly warm up from large
number of people present. Space temperature will glide slightly during the 1-2 hour
event, but will remain comfortable. Without pre -cooling, the existing hydronic system
would not be large enough to satisfy extreme short periods of maximum cooling
demand.

Additional upgrades and maintenance improvements to the hydronic system will also
include resizing and replacing the re -circulating pump, checking existing valves for
proper operation, checking for leaks, flushing and treating the entire closed loop
water and cleaning the existing coils system.
Controls
A new automated temperature control system will be required for the dual
temperature water system to operate efficiently. To simplify environmental control for
the sanctuary, a central interface point for the control system should be provided to
simplify scheduling and temperature adjustments. It is recommended that an
override button be accessible to church staff so that the sanctuary heating/cooling
system can be operated any time for limited periods. Church staff will also be able to
adjust space temperature for the sanctuary during these override periods. Since pre -
cooling is more complicated, it is recommended that three to four event categories be
created for pre -cooling strategies. In order for the church to initiate a typical event, a
schedule or telephone call can be made to a 24-hour service center with modem
access to the control system. The service center will then automatically program the
system to operate according to the scheduled event. This type of system control will
require a maintenance contract with a control/service company as well as installation
of a dedicated telephone line for the control system.
The classrooms and fellowship hall will need a new heating system. Since the
ductwork has to be replaced for the impending re -roofing and the existing cooling -
only units need to be replaced as well, the most efficient remodel will be to install new
rooftop Heat Pump units capable of both heating and cooling the space. These units
will be provided with electronic programmable controls to provide ease of use and yet
restrain equipment runtime during unoccupied periods.
Roof Replacement
The church is considering replacement of the roof over the classrooms and flat areas
of the walkways and sanctuary. The new roof is being considered because of the
deteriorating conditions of the current roof and the resulting costly repair bills.
Integrating the roof replacement with the mechanical and electrical project will
provide for proper coordination between the trades and help minimize multiple points
of contact for construction.
Two roofing contractors have visited the facility and have tendered proposals for the
work. The table on the following page (Table 1) shows how the roofing proposals
compare to each other.
Our initial recommendation is for option 2 from Alpine Construction. Please note that
the proposals explicitly warn that dry rot damage may be present and that the
required repair of such damage is not covered in the proposal. Additional costs for
dry rot repair must be allowed for when budgeting money for this project.

Energy Analysis of Proposed Scope of Work
It is important to define "cost avoidance". Due to the fact that the project will be adding
additional energy consumption for cooling the sanctuary and the anticipated increase in
usage of the facilities in general, the actual energy consumption and costs compared to
previous years may not decrease. In fact, the energy consumption may increase
because of increased usage in the summer months. However, how much higher would
the energy costs have been if energy efficient design was not utilized? Cost avoidance
is the appropriate comparison of what it would cost to utilize the existing equipment,
with the addition of standard efficient air conditioning for the sanctuary, versus the
proposed energy efficient design to meet the expanded usage needs. Had the church
gone forward with emergency and minimum first -cost replacement of the central plant
boiler and expanded the usage of the facilities, they would have experienced energy
costs 28% higher than it would take to operate the proposed efficient systems.
However, because these energy and operational improvements are being considered
for installation, its reasonable to estimate that there will be savings generated from
these comprehensive efficiency upgrades when installed.
Highlights of the proposed energy efficient design:
• New heat pump rooftop units for the classroom wing with SEER ratings greater
than 12.
• Removal of all existing heating hot water fan coil units in the classroom wing.
• High efficiency hot water boiler — up to 85% efficient.
• Replacement of the failed hot water supply lines to the Sanctuary.
• Reconditioning of the HVAC unit for the Plymouth room and installation of a heat
strip.
• Cleaning of the existing air handler coils in the Sanctuary.
• Automated temperature control system with simple user interface. EMS capable,
including pre -cooling strategies for Dual Temperature Water System.
• Dual temperature water system with automatic changeover.
• Properly sized heating/cooling equipment.
• New rooftop ductwork lined with insulation.
• New energy-efficient, air-cooled chiller.
• Newly commissioned systems, operating at design performance.
• (3) year preventive maintenance and remote monitoring services for all HVAC
equipment and temperature controls.

Beni Steel Tube Construction
Introducing a new line of Hot Water
Boilers incorporating a built-in finned
steel tube bundle in addition to the
standard bailer tubes. These heavy
duty finned tubes are placed above
the standard Porker tubes, and they
significantly increase the amount of
heat absorbed from the flue gases,
thus increasing boiler efficiency.
With the additional hearing surface,
the already long Parker Hot Water
Baler life is extended even further.
The efficiency with Atmospherr
Burner firing is 82.84%, and with
our Premix Metal Fiber Lsw NOx
Burner rhe efficienry is 85%. Test
units have been in the field under
harsh conditions aperaring Success-
fully for 5 years.

IntelliPak® Air -Cooled Chillers
In addition to the many standard
features of the 10 and 15 -ton air cooled
Cold Generator® chiller, there are
several added benefits which make
selection, installation, and service
easier.
Flexibility
Footprint
Central to the design of any project is
the operating envelope of the air-
cooled packaged chiller. With this in
mind, Trane builds the chillers to make
the most efficient use of the available
installation space. The Trane CGA
model chillers are extremely compact.
They have the lightest weight, the
smallest footprint, and the lowest
silhouette of any chiller in the industry.
Weight Reduction
The weight of the 10 and 15 -ton units
has been reduced up to 27 percent in
comparison to previous models. Less
weight results in less stress on building
supports and greater handling ease.
Features and 109 15 Tons
Benefits
Installation Optional Features
Installation time and effort are reduced
when dealing with a significantly
smaller and lighter unit. In addition,
having electrical and water connections
on the same side of the unit and a
single -point main power connection
serves to make installation easier. The
unit arrives at the jobsite fully
assembled, tested, charged and ready
to provide chilled water.
Serviceability
The control panel and unit panels are
completely removable for service
accessibility and convenience.
ICS Interface
Communication with Trane Tracer® or
Tracker® is possible through the ICS
Interface on the 10 and 15 ton Cold
Generator chiller..
• Hot Gas Bypass — Allows unit
operation below the minimum step of
unloading.
• Low Ambient Head Pressure
Control — Modulates the rpm of the
fan motor in response to outdoor
ambient temperature and unit head
pressure. Provides unit cooling
operation down to outdoor
temperatures of WE
• Coil Guard — Metal grille with PVC
coating to protect the condenser coil.
• Isolation — Neoprene in shear or
spring flex isolators.
• Power Supply Monitor — Provides
protection against phase loss, phase
reversal, phase imbalance, incorrect
phase sequence and low line voltage.
• Elapsed Time Meter/Number Starts
Counter — Records number of
compressor starts and operating
hours.
9 Flow Switch — Required as a safety
interlock to prevent operation of unit
without evaporator flow (available
option for field installation only).
• Integrated ComfortTm Systems (ICS)
Interface — Provides the ability to
communicate with Trane Tracer® or
Tracker® building management
systems via a Thermostat Control
Module — (TCM).
• Gauges — Monitor suction and
discharge pressures.

Stand -Alone Unit
Interface to stand-alone units is very
simple; only a remote auto -stop or
chilled water flow interlock signal for
scheduling is required for unit
operation. Signals from the chilled
water pump contactor auxiliary or a flow
switch are wired to the chilled waterflow
interlock. Signals from a time clock or
some other remote device are wired to
the external auto -stop input. Unit
controls do not provide an output to
turn pumps on and off.

Chilled Waterflow Interlock (Standard)
Trane Integrated ComfortTM System
Interface
A single twisted pair of wires tied
directly between the CGA unit and a
Tracer® system provides control,
monitoring and diagnostic capabilities.
Control functions include auto/stop,
compressor operation lockout for kw
demand limiting. In addition, the Tracer
system can provide sequencing control
for two or three CGA units on the same
chilled water loop. Pump sequencing
control can be provided from the Tracer
system also. Sequencing of two CGA's
can be accomplished with the DDC
Chiller Sequencer.

ELECTRICAL CONTROL SYSTEM
The controls used on CGA 10 and
15 -ton units are classified either as
"safety' controls or "operational"
controls. Brief descriptions of the
specific safety and operating controls
used in the CGA control scheme are
provided in the following paragraphs.
Refer to the following control
descriptions for control settings.
UNIT SAFETY CONTROLS
Low Pressure Cutout (LPC01,
LPCO2) Mounted below the unit
control box are two low pressure
cutouts that open and stop
compressor operation if the operating
pressure drops below 38.5 ± 1 psig.
The cutout automatically resets when
the pressure reaches 44.5 ± 2 psig.
The LPCO is a SPDT device. If it
opens at low ambient start-up, it will
energize ODF relay, stopping the
outdoor fan(s) while the compressor
remains energized through the LAST
(Low Ambient Start Timer).
High Pressure Cutout (HPC01,
HPCO2) —These units have high
pressure cutouts that open and stop
compressor operation if the discharge
pressure reaches 400 ± 10 psig. The
cutout automatically resets when
pressure drops to 250 ± 15 psig.
Reset Relays (FIRS, RR2) — If the
unit is shut down by the low pressure
cutout (or high pressure cutout), the
reset relay locks out the compressor
contactor (CCS, CC2). This prevents
the system from recycling until the
condition that caused the low (or
high) pressure cutout to trip is
determined and corrected.
CAUTION: To prevent unit damage,
do not reset the control circuit
until the cause of the safety
lockout is identified and corrected.
To reset RR1 and RR2, open and
reclose the unit disconnect switch.
Low Temperature Cutout (LTC) —
The LTC is designed to disable the
unit if the leaving water temperature
falls too low. The LTC's remote
sensing bulb is mounted at the outlet
end of the evaporator, where it
monitors leaving water temperature.
During normal unit operation, if the
low temperature cutout (LTC) senses
a temperature falling to 36°F ± 3.0°F,
the LTC will open to interrupt
compressor operation. (Manual reset
is required.)
Controls
Motor Overloads —These units
have internal compressor and
condenser fan motor overloads_
These overloads protect the motors
from overcurrent and overheating
conditions and automatically reset as
soon as they cool sufficiently.
UNIT OPERATIONAL CONTROLS
Water Temperature Thermostat
(WTT) — System operation for 10
and 15 -ton CGA units is governed by
a two-stage water temperature
thermostat (WTT). The remote
sensing bulb of this device is factory -
installed in a bulb well located on the
evaporator water inlet; here, it
monitors the temperature of the water
returning to the evaporator.
Low Ambient Start Timer (LAST) —
When one of the two timers
energizes, the low pressure control is
bypassed for four minutes, this allows
time for suction pressure to build
sufficiently for the low pressure cutout
contacts to close.
Hot Gas Bypass Timer, Solenoid
(HGBT, HGBS) —The hot gas
bypass option is factory -installed only,
and is used in a chilled water system
to keep the first stage compressor on-
line during short no-load or light -load
conditions. When Water Temperature
Thermostat (WTT) first stage opens,
24 -volt power is supplied to the
Compressor Contactor (CC1) through
Hot Gas Bypass Timer (HGBT) pins
one and four. Power is also applied
from WTT-B to HGBT coil (fixed 30 -
minute time delay pick-up) and to the
Hot Gas Bypass Solenoid (HGBS)
through HGBT pins eight and five. If
first stage cooling remains satisfied
for 30 minutes, HGBT will energize
and shut down the compressor. If
there is a call for cooling during
HGBP mode, the unit will return to
cooling mode.
The adjustable hot gas bypass valve
is factory set at 70 psig.
Note: Hot gas bypass is available
only on the lead compressor circuit.
29
Anti -Short Cycle Timers (ASCT1,
ASCT2) — An anti -short cycle timer is
provided in each compressor control
circuit to protect the compressors from
starting too frequently. This can occur
as a result of just over 0%, or just over
50% of the unit capacity, or because of
sudden power outages of short
duration. Whenever the contacts of
the water temperature thermostat
(WTT) open — or when there is a
momentary power outage — the anti -
short cycle timer will lock out
compressor operation for three
minutes.
Delay Between Compressors (DBC)
—The delay between compressors
prevents both compressors from
starting at the same time by delaying
compressor number two for 30
seconds.

SEQUENCE OF UNIT OPERATION
Refer to the unit wiring schematic
pasted to the inside of the control panel
cover when reviewing the control
sequence described below.
Refer to the legend on the previous
page for an explanation of the
acronyms used in this sequence.
10 -Ton Operation
With fused disconnect switch closed,
power is supplied to the crankcase
heaters and the 24 -volt control circuit.
Starting the chilled water pump closes
the CWPS auxiliary contacts and
completes the flow switch.
When the water temperature rises
above the WTI's setpoint, its first stage
switch closes, allowing power to pass
through CWPS auxiliary contacts, the
flow switch, the LTC, the ASCTI, the
RR1 contacts, the LPC01, and the
HPC01 to energize the CC1 coil. This
starts compressor number one and the
outdoor fan.
If compressor number one can't satisfy
the cooling demand, WTT's 2nd stage
switch closes, allowing power to pass
through the CC1 auxiliary contacts, the
DBC, the ASCT2, the RR2 contacts,
the LPCO2, and the HPCO2 to energize
the CC2 coil which starts compressor
number two.
15 -Ton Operation
With fused disconnect switch closed,
power is supplied to the crankcase
heaters, and the 24 -volt control circuit.
Starting the chilled water pump closes
the CWPS auxiliary contacts and
completes the flow switch, allowing
power to pass through the LTC to
energize the CWFIR.
When the water temperature rises
above the WTTs setpoint, its first stage
switch closes, allowing power to pass
through the CWFIR contacts, the
ASCT1, the RR1 contacts, the LPC01,
and the HPC01 to energize the CC1
coil. This starts compressor number
one and outdoor fan number one.
If compressor number one can't satisfy
the cooling demand, WTTs second
stage switch closes, allowing power to
pass through the CWFIR contacts, the
DBC, the ASCT2, the RR2 contacts,
the LPCO2, and the HPCO2 to energize
the CC2 coil. This starts compressor
number two and outdoor fan number
two.

LOW AMBIENT OPERATION
Field Installed Head Pressure
Control Accessory
Standard units will operate in outdoor
ambient temperatures down to the
values shown in the "General Data"
section of this catalog. This accessory
will enable units to operate down to
much lower temperature extremes (see
"General Data" section of this catalog).
Head pressure control for CGA units is
regulated by means of a field -installed
head pressure accessory which varies
condenser fan speed in relation to
discharge pressure.
When discharge pressure is 270 psig
or higher, the condenser fan runs at full
speed. At pressures between 270 psig
and 180 psig, the fan speed is adjusted
(increased or decreased) in direct
relation to the pressure, with minimum
fan speed (10 percent of rated motor
rpm) occurring when the pressure
reaches 180 psig. At pressures below
180 psig, the fan will not run. When
discharge pressure rises to 180 psig,
the fan will start and run at the reduced
speed. Fan speed will continue to
increase, as the pressure Increases,
until full speed is reached at 270 psig.

from 1.5 tons through 5 tons thereby pro-
viding great installation flexibility on shop-
ping malls, factories, schools, and other
commercial buildings where a mix -match
of tonnages and utilities is desired.
• WATER -SHED Base
Superior water integrity is accomplished
with the WATER -SHED base pan having
elevated downflow openings and a pe-
rimeter channel that prevents water from
draining into the ductwork.
• Demand Defrost Control

josed and replaced with the removal of
one panel that is attached with two
screws.
Features
and Benefits Contents
• High Efficiency
I MPACK performance is among the highest
in the industry.
• DuratuffTM Plate Fin Coil
Refrigeration coils are built with internally
enhanced copper tubing for high effi-
ciency with less coil area.
• T-TOPTM

Features
and Benefits
• Convertibility
IMPACK units are easily converted from
horizontal to down flow with the removal
of one screw from each panel. Accord-
ingly, the need to stock both dedicated
horizontal and dedicated down flow
models has been eliminated.
• Installation
The ease of installation and application
flexibility exhibited through the design re-
duce both field time and material.
• Structure
The units are lighter weight through the
use of high technology components
thereby reducing mounting structure re-
quirements and difficulty when man-
handling.
• Handling
The three-way wooden skid allows for
easy loading between the wheel wells on
pickup trucks for transporting to job sites.
• Application
he low profile horizontal duct take -offs
eliminate the need for expensive transi-
tion ducts in crawl space applications.
• Duct Flanges
Only IMPACK has downflow duct flanges
for duct attachments that preserve the
built-in water integrity.
• Service
All wiring is both numbered and color
coded thereby reducing training and ser-
vicing costs related to circuit tracing and
components replacements.
4
• Easy Fan Maintenance
A plug on the outdoor fan motor allows
the top cover to be removed completely
without the hassle of cumbersome wires.
The unique service orifice ring allows the
indoor fan motor/blower to be removed
as a unit.
• Corrosion
The drain pan is engineered material and
eliminates the need for coatings and
sealers to prevent sweating and corro-
sion. The heavy gauge, zinc -coated steel
cabinet has a weather resistant enamel
finish that stays attractive and protects
your investment for years.
• Low Ambient Control
Standard cooling operation to 550 as
shipped, zero degree ambient cooling is
accomplished with two kits. One for low
cost installations when full tonnage is not
needed. The other kit maintains head
pressure and full capacity at zero de-
grees.
*Quality and Reliability Testing
We perform a 100% coil leak test at the
factory. The evaporator and condenser
coils are leak tested at 200 psig and
pressure tested to 450 psig respectively.
In addition the IMPACK designs were rig-
orously rain tested at the factory to en-
sure water integrity. Shipping tests are
performed to determine packaging re-
quirements. Factory shake and drop
tests are used as part of the package de-
sign process to help assure that the unit
will arrive at the job site in top condition.
Additionally, all components are in-
spected at the point of final assembly.
Substandard parts and components are
identified and rejected immediately.
Every unit receives a 100% run test be-
fore leaving the production line to make
sure it lives up to rigorous Trane require-
ments. We at Trane test our designs at
our factory and not on our customers!

• Standard Thermostats
No special thermostats are needed with
IMPACK units.
• Filter Frame Kit
The IMPACK filter frames accept stan-
dard filters and fit inside the unit. The
frame kits function in either horizontal or
downflow duct configurations.
• UNI -CURB
One universal curb fits all the IMPACK
models. It ships knocked down. The curb
design incorporates the popular locking
tabs for quick and easy assembly. Full
perimeter curbs are also available for all
models.
• Economizer
The economizer fits inside the unit with
only the rain hood and barometric relief
on the outside. Cabling is shipped with
the economizer. This cabling is easily
routed to the control box where it termi-
nates in low voltage pigtails. The econo-
mizer features a fully modulating low
voltage motor eliminating the need for
any high voltage wiring. The economizer
must be used with the filter frame kit ...
no return air filter in the economizer kit. A
dry bulb sensor is shipped with the
economizer. The downflow economizer
was not designed for use in horizontal
applications. A horizontal only econo-
mizer is available. Heat pump applica-
tions require a relay kit.

introduction
The LGC is a pan of the LANgate family and provides
communications between a workstation and a control
module network (CMnet) consisting of fewer than 100
modules. The CMnet is a peer-to-peer local area network
which uses a "token -passing" protocol to allow all control
modules to communicate with one another with equal
authority. A workstation can communicate with the CMnet
through the LGC when direct -connected (DC) or modem -
connected (MC), or it can communicate on the CMnet
through any other module with z Direct -Network (DN)
connection. The LGC does not have a Direct -Network
(DN) connection.
The LGC communicates with the CMnet through an EIA -
485 port. Signal integrity on the CMnet is affected by the
wire gauge and the total amount of wire in the segment. A
segment is the network of modules between gateway
modules or repeaters. Repeaters, which boost communica-
tion signals, are available from ALC for legacy (9600 bps
or 38,4 kbps) CMnets and for ARCNET (156 kbps)
CMnets. Ask for part number REPOPT or REP485,
respectively.
The LGC provides two EIA -232 console ports and an
Access port for connecting to a workstation, portable
computer, or modem. These ports can communicate at
speeds of 9600 bps or 38.4 kbps. The Access port requires
a signal converter (ALC part number APT) and is designed
for transferring memory or troubleshooting. When an
ARCNET CMnet is used, the Access port can receive
colors but cannot receive alarms.
NOTE: You must use FB Link v2.7a or later in order to
download to any module containing Exec 6 or later.
Specifications
Power: 24 VAC f 10%, 50-6014z, 7.2VA
Console Ports: Two EIA -232 serial ports (one D -sub 9 -
pin connector and one 5 -pin pluggable screw terminal
block) switch selectable for 9600 bps or 38.4 kbps.
CMnet Port: EIA -485, twisted pair, selectable for 9600
bps, 38.4 kbps, or 156 kbps, optically isolated.
Status Indication: Visual (LED) status of EIA -232
communication, CMnetcommunication, running, errors,
and power.
Temperature Range: 0-130 °F (-17.8 to 54A °C);
relative humidity 10-901/9, non -condensing.
Protection: Built-in surge and transient protection
circuitry.
Listed By: UL 916 (PAZX), C -UL C22.2 No, 205-M19
(PAZX7).
Mounting
Mount the LGC in an enclosed panel using the four holes
provided on the module's cover plate (see figure 2). Make
sure that nothing comes in contact with the back of the
printed circuit board, and leave approximately 2 inches (5
em) on each side for wiring.
The LGC is designed to be mounted inside the building
envelope. All warranties are void if mounted outside.

GRANT TO UNITED CONGREGATIONAL CHURCH
-------------------------------------------------------------------
-------------------------------------------------------------------
WHEREAS, the State has mandated that beginning January 1, 1998, the City of
Lodi is obligated to fund various programs through a Public Benefits Charge (PBC)
based on a historical electric revenue requirement; and
WHEREAS, the requirement amounts to approximately $1M per year that must
be dedicated to qualifying programs such as energy efficiency. A further stipulation is
that these efforts must be done on the customer's side of the meter in order to qualify;
and
WHEREAS, the City of Lodi Electric Utility, in partnership with Energy Masters,
International, completed a Comprehensive Energy Engineered Analysis of United
Congregational Church located at 701 S. Hutchins Street. As a result of this
assessment, it has identified specific energy conservation measures and the associated
energy, maintenance and operational savings that could be implemented as part of
United Congregational's overall construction project. Specifically, United Congregational
Church will be installing and/or retrofitting the following items within their facility:
> removing a number of inefficient HVAC (heating & cooling) units on the classroom
area of the church property, and installing new, highly efficient HVAC heat pump
units;
> retrofitting all existing classroom, office space and sanctuary lighting with state-of-
the-art fluorescent lighting and associated controls;
> installing a new, 15 -ton energy efficient air cooled chiller (air conditioning system) for
the sanctuary;
> replacing the existing boiler, with a new, highly efficient piece of equipment that will
compliment the aforementioned 15 -ton chiller;
> installing a new automated control logic system (often referred to as an energy
management system) designed to allow church personnel the ability to remotely
schedule (turn on/off) and operate the facilities HVAC system.
WHEREAS, the Public Benefits Program Grant in the amount of $75,769.75
reflects a 25% energy efficiency incentive rebate for the total cost of the project to United
Congregational Church. The 25% rebate is consistent with all other rebates offered to
commercial and industrial electric utility customers throughout Lodi that participate in the
City of Lodi Energy Services Partnership Program (which is an element of the City of
Lodi Public Benefits Program).
WHEREAS, the Electric Utility Department recommends that the City provide a
Public Benefits Program Grant of $75,769.75 for a demand-side management project at
United Congregational Church.
BE IT RESOLVED, that the Lodi City Council hereby authorizes the City
Manager to provide a Public Benefits Program Grant in the amount of $75,769.75 to
United Congregational Church for a Comprehensive Energy Engineered Analysis.
