CODE: C 17YPE: CONSENT PUBLIC NO
HEARING:
SUBJECT: Authorize Execution of Change Order No. 4to City Secretary Contract No. 29110-A7 with
Johnson Controls, Inc., in the Amount of$211,584.00 for a Total Contract Amount of
$3,397,949.00 for the Energy Savings Performance Contract at Selected City-Owned
Facilities (ALL COUNCIL DISTRICTS)
RECOMMENDATION:
It is recommended that the City Council authorize the execution of Change Order No. 4 to City
Secretary Contract No. 29119-A with Johnson Controls, Inc., in the amount of$211,584.00 for a
total contract amount of$3,397,949.00 for the Energy Savings Performance Contract at selected
City-owned facilities.
DISCUSSION:
This proposed Change Order No, 4 will compensate Johnson Controls, Inc., for installing several
additional energy saving measures in City buildings. These buildings have been included in previous
Performance Contracts with Johnson Controls. The activities that will be implemented include
computer server changes, water temperature sensors and flow meters, cooling tower sequence of
operations, optimal starUstop programming, zone sensors calibration, City Hall chiller integration and
sequence of operations reprogramming and Metasys upgrade.
The annual electricity savings are estimated to be $15,119.90 for a simple payback of 14 years. This
recommended work will optimize efficiency while also increasing comfort and maintaining upgraded
requirements to previous improvements.
The original Phase VI-b contract is stimulus-funded by a grant in the amount of$6,738,300,00 from
the United States Department of Energy (DOE)through their Energy Efficiency and Conservation
Block Grant(EEC13G) Formula Program. The majority of this recommended work will be funded by
this same federal grant in the amount of$195,634.16), with the balance in the amount of$159949.84
funded from the City's Resource Conservation account.
M/WBE — Johnson Controls, Inc., agrees to maintain its initial M/WBE commitment of 15 percent that
it made on City Secretary Contract No. 29110-A a nd extend and maintain that same M/WB E
commitment of 15 percent to all prior change orders up to and inclusive of this change Order No. 4.
Therefore Johnson Controls, Inc., remains in compliance with the City's M/WBE Ordinance and
attests to its commitment by its signature on the Acceptance of Previous MIWBE Commitment form
executed by an authorized representative of its company.
These upgrades will include buildings in ALL COUNCIL DISTRICTS.
FISCAL INFORIVIATIONXERTIFICATION:
The Financial Management Services Director certifies that funds are available in the current operating
budget, as appropriated, of the Grants Fund and the Special Trust Fund.

TtI 11,
t
Estimated annual energy savings for this work is $15,160 resulting in a simple payback of
14.0 gears.
Total estimated DBE participation for this proposal is 12%.
This proposal includes the following scope of work.
Scope #1 — Move software from A X-too server to A -201 server
1. Remove software object rapping for City Haiti, City Hall Annex, Public Safety Building
and Central Library from existing ADC Zoo.
2. Add software object mapping for city Hall, city Hall Annex, Public Safety Building and
Central Library from existing ADC 201. Add to existing graphics the same graphics that
were used in AS Zoo to support sane software objects.
Scone ##2 — Faecal ibrate water temperature sensors & CHW flow meter— Citv Hall
1. Inspect all water temperature sensors (chilled, condenser, heating water, and 2-pipe
changeover system) and provide labor for repairs needed on existing equipment. If
necessary, relocate temperature sensors for better performance.
2. Inspect chilled water flow meter and provide labor for repairs needed on existing
equipment.
Scope #3 — Optimize cooling tower sequence of operation — City Hall Central Plant
1. Install two 2 new 20-HP VFD units on existing cooling tower fan motors (3rd fan already
has a F .
2. Install three new " 2-position electric motorized isolation valves on existing cond en er
water inlet lines (one for each cooling tower cell).
. Rewrite/reprogram cooling tower sequence of operations.
4. JCl will program an operator adjustable set point for the condenser water temperature
that will not adjust lever than the 80 degrees required by the chillers.
5. Inspect all temperature sensors used on the operation of the cooling towers. Verify
bypass valve operation.
Scope ## — Ootimal AHU start/stop ro rammin — Utv Hall City Hall Annexe PSB
1 . Write optimal starUstop programming for all scheduled areas.
2. J e I will program optimal start stop of all areas that are currently ched u tied. In order to
program optimal start top it will be necessary to break schedules up into individual
zones. An example of this is by thermostats. If multiple thermostats are within one area
or room then they will be courted as one zone. If only one thermostat exists within a
room then that single thermostat will be programmed as one zone.
Scope #b — Recalibrate air temperature sensors — City Hall, City Hall Annexe, PSB
1 . Inspect & calibrate all air temperature sensors that are off 2 degrees or more C only .
Page
PP
Scope # — New DDC room sensors — City Hall
1. Provide and install seven new DDC zone sensors to control and monitor several City
Council areas on the second floor of City Hall that are currently being controlled by
pneumatic and electronic controls.
City Council Chamber - Four — includes control of existing reheat bones
Pre Council Room - Two — includes control of existing reheat bones
Pre-Council Break Boom — One 1 — monitor room temperature only
Scope #7 — Carrier chiller integration — Citv Hall Central Plant
1 . Provide, install and commission 3 B Cnet MSTP translators to replace a DataLink
module. Translators will be installed in existing DataLink enclosure and will be connected
to three 3 existing Carrier chillers.
2. Upgrade existing NAE to MS NAE 1 -2.
3. Rearrange existing N2 wiring to one port.
4. Use second BANET MSTP port to communicate with Carrier chillers.
5. Create Carrier chiller database in Metasys.
Scope # — Uparade ADX-200 server software
1 . Upgrade existing AD C-200 server software to latest version
2. Upgrade the following Network Controllers software to latest version:

Sco a # — Owimize Central Plant seauence of o eration — City Hall Central Plant
1. New sequence of operation will be written to the DX controller.
2. Sequence of Operation. Building load less than 250 tons, small chiller will run. In the
event chiller load goes over 250 tons and holds for a period of 20 minutes (will be
Page 3
adjustable by the operator) system will bring on one of the larger chillers that has the least
amount of run time (run time being calculated within the DX program). After the load has
been met for 10 minutes, the small chiller will stage down. to the v nt the larger chiller is
not able to maintain in tyre load and 20 minutes have passed, the m ll chiller will stage
back on to assist with the load (the stage up time limit will also be adjustable by the
operator). These time delays will keep the hill r from short cycling on and off.
Estimated installation time for this work is approximately eight (8) weeks.
