SUBJECT: Status Report on the Energy Conservation Performance Based Contract
---------------------------------------------------------------------
---------------------------------------------------------------------
With the approval by Commission of the Energy Conservation Performance Based Contract on
January 21, 1998, Property Management and Johnson Controls Inc. began a major retrofit of
mechanical systems, lighting systems, and energy management systems in 26 separate, City owned
buildings. To date, the construction portion alone over a four month period has provided the City
with direct energy savings of $91,937.00 and has also earned for the City, an additional $90,846.05
in direct energy rebate incentives from Florida Power and Light. Operational savings have also been
obtained by the cancellation of service contracts where new equipment has been installed and new
equipment warranties are now in effect.
These savings are the direct result of the retrofitting and replacement of the following electrical and
mechanical equipment:
1) Lighting:
To date, over 9,000 light fixtures have been retrofitted. This includes the replacement
and installation of over 8,770 high efficient ballasts and over 22,000 new energy
efficient lamps.
2) BV AC:
a): A new 500 ton high efficiency cooling tower has been installed at City Hall to replace
the deteriorated tower.
b): Two new 170 tons high efficient centrifugal chillers have been installed in City Hall
to replace the low efficiency, and deteriorating units.
c): Variable speed drive motors are currently being installed in all air handling equipment
to replace outdated direct drive technology.
d): A new AlC coil has been installed on the roof of the City Hall Building to handle the
new chiller loads.
e): Centrifugal chiller optimizations have been completed at the Police Department
Building. The building has also received the addition of variable speed motors for the
air handling equipment.
3) Energy Management Systems:
a): New, state of the art, energy management systems are being installed in the City Hall
Building, Police Department Building, Scott Rakow Youth Center, and the South
Shore Community Center. The new system will allow for zone control oflighting and
AlC equipment without the need for the entire facility to be "on". This also will allow
for system changes to be made on each building from a remote centralized location.
The system will also contact repair personnel directly, by means of an automatic
dialing system, in the event of any system problem. The energy management system
will provide setback control for non-use times. These systems will provide much
better control while providing energy deductions for these facilities.
b): Programmable thermostats and time clocks are being installed in 8 other City
buildings to allow for a setback of equipment during non-use times to provide energy
consumption reductions.
The FPL rebates have been applied toward the costs of the Performance Based Contract as a down
payment of the $2,000,000.00 of new equipment the City is receiving. The energy savings and
operational savings obtained during the construction process represents real savings to the City as
the energy savings will not be part of the Performance Based Contract until the construction portion
of the project is complete.
Property Management has applied and has been accepted in the Federal Environmental Protection
Agency's (EPA) "Green Lights Energy Star Program". This will provide the City with national
recognition in the alliance in energy efficiency matters and will provide the City the ability to submit
buildings for the national "Energy Star" awards.
Although these retrofits have been somewhat painful at times in producing some "warm days" in the
City Hall building due to the replacement of the entire mechanical infrastructure in the building, the
completion of the project by mid-November will provide a controllable system that can be set to
provide comfort levels to accommodate each Department's specific needs.
The attached report from Johnson Controls provides a cost avoidance report, measured specific
performance guarantee per facility, actual electric billing data for each affected facility, and the
electrical utility baseline data. Also attached, is a report of the the remaining facility improvement
measures and their current status and timetables for the completion of the remaining projects of the
Performance Based Contract.
Attached also are photographs of before and after conditions in the facilities
Because the Performance Based Contract is based on a 80% factor of the estimated energy savings
by the energy auditors and any additional savings would be received directly by the City, Property
Management will continue to seek any additional measures that will provide additional energy savings
to the City. Property Management staffwill continue to work with Johnson Controls, EP A, and FPL
to achieve that goal.
If you have any questions, please do not hesitate to call me at x7010.
