Adopt Resolution No. 2007-005 approving contract documents, special provisions and
specifications, and authorizing the City Clerk to advertise for bids to perform the Safety Center HVAC
Controls Upgrade, Contract FAC 07-01.
ITEM EXPLANATION:
In 2003, the General Services Division of Public Works began a program to review the overall energy
consumption of the major facilities owned and operated by the City of Carlsbad. A strategy was
formulated to make changes to various systems that utilize energy. A program was formulated and
various projects were recommended to upgrade and modernize the lighting systems and Heating,
Ventilation and Air Conditioning (HVAC) systems to maximize energy efficiency and lower operating
costs. At the time many of our facilities were constructed, the original lighting and HVAC equipment
was far less energy efficient and substantially less economical to operate than newer technologically
advanced modern equipment. Much of the existing equipment had also reached the end of, and in
many cases, exceeded the industry standard life expectancy for commercial lighting systems and
HVAC equipment.
An integral part of this program was a partnership between the General Services Division and the
San Diego Regional Energy Office (SDREO). SDREO offered a number of valuable services to the
City. SDREO performed energy audits of our facilities, made recommendations for upgrades, provided
energy cost savings projections and offered various financial incentives to the City including funding
future projects and providing rebates at the completion of projects that were currently in the design
phase if the City would incorporate various recommendations to them. Staff instructed our Engineers
to make changes to planned projects in order to maximize energy savings and to insure that the
maximum financial incentives were realized by the City. Energy projects that have been completed as
of December 2006 include installing energy efficient lighting and replacing the HVAC equipment at the
Calavera and Stagecoach Community Centers, replacing HVAC equipment at the City Council
Chambers, replacing HVAC equipment at the Georgina Cole Library, and replacing the centrifugal
chiller at the Safety Center.
The Safety Center is a 53,000 square foot building completed in 1986 that serves as the
administrative headquarters for Police and Fire services in the City of Carlsbad. The HVAC system is
a pneumatically controlled valve operated system that regulates heating and cooling through the use
of heated and chilled water in various zones throughout the building. The current HVAC system
operates purely on a temperature range basis and has no provisions for adjusting which portions of
the building are heated and cooled. This control system requires that the entire 53,000 square feet be
heated and cooled without regard to the actual need to condition the individual zones. Although the
Safety Center operates on a 24 hour per day basis, many portions of the building that are occupied
during normal business hours are unoccupied during weekends, holidays, and at night. The current
system does not allow central control and adjustment of heating and cooling to individual portions of
the building. This results in inefficient use of energy and unnecessary costs to condition unoccupied
space.

The proposed project makes numerous changes to the current HVAC control system.
The pneumatically controlled valve system and air compressor are removed. New electrically
operated, computer controlled valves will be installed on each heat exchanger. Package HVAC units
that operate the Conference Center and Dispatch will be integrated into the new control system.
These upgrades will allow automated and computerized control of the HVAC system from the central
computer terminal located in the Facilities Maintenance office and by laptop computer at the Safety
Center. Individual zones can be programmed to operate during periods the space is occupied and
can be shut down when the space is not occupied. In order to allow flexibility, individual zones can be
activated for a pre-programmed period of time at the local thermostat to insure that the system will
operate in these zones to meet immediate operational needs.
The Engineer's estimate for construction and contingency is $200,000. Project design and
construction inspection costs are estimated at $35,000. The City has received a financial incentive of
$52,249 from SDREO leaving a final estimated net cost to the City of $182,751. The annual energy
cost savings is estimated at $54,300. The estimated payback for the project is 3.36 years.
Sufficient funds are available in the General Fund, Facilities Department Capital Outlay account to
complete the project.
Plans and specifications are on file at the office of the General Services division.
ENVIRONMENTAL IMPACT:
This project has been determined to be exempt from environmental review per CEQA (14 Cal Code
Reg §15301) - minor alteration of an existing facility.
