INTRODUCTION
This report has been prepared following a review of the original building design drawings, and
an evaluation of the existing HVAC system serving the Jefferson City Police Department Facility
located at 401 Monroe Street, Jefferson City, Missouri. The HVAC system has been previously
evaluated by an engineering firm, and a performance contracting firm with widely differing
opinions for upgrading the facility. MECO Engineering has been asked to evaluate the building
HVAC system and provide additional commentary and recommendations as to the best solution
for future system upgrades.
HISTORY
The Jefferson City Police Department was constructed in 1979. This 37,600 square foot facility
includes (2) levels which includes administrative office space, training and evidence rooms and
utility/mechanical space located in the lower basement level.
Cooling is provided from a nominal 60 Ton McQuay chiller located in the basement with a
remote air cooled condensing unit located outside the building. The chiller is original to this
building and is increasingly becoming unreliable. Presently, it has a refrigerant leak at the chiller
barrel that has been repaired in a temporary fashion that has added a sense of urgency to
implementing improvements to the entire system.
Heating is provided through a gas-fired boiler which replaced the original electric boilers in the
early to mid-1980's. Since the original design included electric boilers, combustion air provisions
were added to serve the gas-fired equipment, however the combustion air is very marginal and
wouldn't meet today's code requirements.
Four large air-handling units (AHU's) located in the basement distribute heating and cooling to
serve various zones as follows:
AHU-1 is a heating only unit that originally served the basement, but is presently not in use. A
series of residential split systems have been installed to condition this area.
AHU-2 is a multi-zone heating/cooling unit serving (2) zones on the main level.
AHU-3 is a single zone heating/cooling unit that serves classroom space on the main floor.
AHU-4 is a multi-zone heating/cooling unit serving (4) zones on the main level.
Two large exhaust fans located in the basement were included in the original design to
purportedly meet ventilation requirements for a laboratory and evidence storage. These fans are
interlocked with two of the large AHU's (AHU-1 and AHU-4) to start, and run, simultaneously
with each respective unit. A laboratory is not presently utilized in the facility, but the exhaust
fans (and associated make up air) remain operational which needlessly exhausts large
quantities of tempered air from the building through a discharge louver in the basement level. It
was noted that these fans must run to prevent pressurization problems within the building with
doors being held open. This creates a large waste of energy due to continually tempering
outside air and then exhausting it from the building. This situation needs to be corrected with
any upgrade to the building.
The existing temperature control system is pneumatic, and no longer functions properly. This
type of temperature control system was widely used at the time that this building was originally
designed, and constructed. Any improvements should include upgraded building controls.
Page 1 of 6
The existing sheetmetal duct system serving the building has become a source of air quality
concern for the building occupants due to dirt and debris in the ducts finding its way into office
spaces. The original duct design included fiberglass duct liner which is now coming loose within
the duct. The Owner contacted a company in an attempt to clean the duct system, but they were
unsuccessful in this effort. It was noted through review of existing drawings, and meetings with
the building occupants, that the original duct system design mixes interior and exterior spaces
on the same zones, and results in inadequate comfort for the spaces served.
It was note that the return air system design utilizes large transfer grilles and ducts to return air
to the basement mechanical room. The air-handling units do not include direct duct connections
to the equipment, but rather the room is actually used a common plenum to serve each unit in
the space. This type of design would not meet current codes due to the return air being drawn
through corridors (means of egress) in some instances.
Finally, we would like to reiterate that the existing equipment has reached its useful life and is in
need of replacement. The existing chiller has a temporary repair of the heat exchanger that will
require a costly repair, or equipment replacement in the near future.
PAST SYSTEM EVALUATIONS
Henderson Engineers Report
In 2008, Henderson Engineers prepared a report for The City of Jefferson that outlined options
for upgrading the HVAC system in the facility. The report included replacement of the existing
HVAC system with one of the (3) options listed below:
Option 1: Variable Refrigerant Volume (VRV), including a dedicated outside air rooftop unit
to provide building ventilation.
Probable cost was noted as $445,000.00.
Option 2: Multiple Rooftop Units (RTU's).
Probable cost was noted as $244,000.00.
Option 3: Rooftop Units with By-pass Variable Air Volume (VAV) Terminal Units.
Probable cost was noted as $282,000.
Construction documents were subsequently prepared by Henderson Engineers that included
the work outlined under Option 3 for RTU's and VAV terminal units. Subsequent cost estimates
for this option had the total project cost at between $300,000 and $500,000. This work was
limited to the main level, but did include the replacement of the ductwork serving this floor.
Ultimately, this approach was not deemed to be a viable solution and was not implemented.
M360 Feasibility Study
More recently, a Performance Contracting Firm, "M360", prepared a feasibility study dated
December 2013 outlining energy upgrades and improvements for the HVAC system. The
recommended improvements included, but were not limited to replacement of the existing
system equipment with a new higher efficiency chiller, condensing style boilers, (2) new variable
air volume (VAV) air-handling units and VAV boxes, new DDC temperature controls and revised
building exhaust fans sized for current building ventilation requirements.
Page 2 of 6
The estimated initial costs for this work were as follows:
• VAV System for Both Floors: $1,069,500.00
• VAV System 1s' Floor Only: 730,050.00
An additional option included a less complex system, variable volume & temperature system
(VVT) to serve the first floor only with a reduced cost of$518,100.00.
Typically, performance contracts offer a guaranteed savings where there are no upfront costs to
the Owner. The energy savings that are realized from the improvements are used to pay for the
upgrades. Again, these upgrades were not implemented.
DISCUSSION
Following review of the existing HVAC system, and meeting with the building user, it is
recommended that any HVAC system improvements include the following goals:
• Revised zoning for better individual comfort.
• Lower operating costs.
• Complete ductwork replacement to address ongoing air quality concerns.
• Address the unnecessary building exhaust air quantities to conserve energy.
• Upgraded temperature control system.
• Provide the ability to phase construction to minimize disruption to the operation of the
facility and accommodate the available project budget.
The preferred recommendations from Henderson Engineers and M360 each address these
goals (with the exception of a complete ductwork replacement), but differ in methodology. Both
firms also offered lesser cost system options, but they each compromise the goals listed above.
The preferred Henderson Engineers recommendation included demolition of the existing HVAC
system equipment, and the installation of a VRV system with a dedicated outdoor air unit
mounted on the roof. It is assumed that this work only included the main level. Their
recommendation would utilized the existing ductwork system for the distribution of fresh air from
a rooftop mounted fresh air unit, so it does not address the dirt and debris that has been noted
as an air quality problem. If properly implemented, it does seem to address the other concerns
with the system performance. As previously noted, the probable cost noted in their 2008 report
was $445,000.00 for the proposed VRV system and fresh air unit installation.
The preferred M360 recommendation included the replacement of the existing chiller, boiler,
new VAV air-handling units, VAV boxes with hot water reheat, revised exhaust air quantities and
replacement of the pneumatic temperature control system with a new direct digital control
(DDC) system. This approach would utilize the existing heating and chilled water piping in the
basement, but would require a heating water loop to be installed in the building to serve the re-
heat coils. Again, if properly implemented this recommendation addresses concerns with the
existing system with the exception of the ductwork replacement and related air quality issues.
Their probable cost listed in their 2013 study for equipment replacement, controls upgrades and
the installation of a VAV system for the entire building was $1,069,500.00, while their estimated
cost for the main floor only was$730,050.00.
In comparing the costs of these two options, it should be noted that the probable VRV system
costs noted in the Henderson Engineers report are somewhat dated, while the proposed VAV
system costs from M360 are more current. Past MECO Engineering projects utilizing VRV
equipment and dedicated outside air units in school renovation projects have been running in
Page 3 of 6
the $26.00 per square foot range. An office setting will likely require more individual zones than
a classroom building, so we would estimate the probable cost to be more in the $30.00 per
square foot range.
We do not have historical costs for a chilled water VAV air-handling system with hot water re-
heat available. However, the costs noted in the M360 estimates do not seem out of line
considering the scope of work that is included in their project description considering the amount
of large equipment that would be replaced.
CONCLUSION
After careful consideration, it is our opinion that a Variable Refrigerant Volume (VRV) system
with a roof mounted outside air unit is the best solution for this facility. If the budget is not
available to renovate the entire building, the work could be limited to the main level and
classroom space at this time. This system upgrade on the main floor would not impact the split
systems that presently serve the basement level.
The basement area could be retrofitted with the same system if the budget allows along with the
main floor, or in the future. Retrofitting this system to the basement at a later date would have
no adverse effects on the main floor. In this instance, it may be possible to utilize the existing
ductwork to distribute supply air from the existing split system zones by replacing the (5)
existing furnaces with a ducted fan coil unit connected to the refrigerant system serving the
main floor of the building. This concept would be explored during design after determining if the
existing zoning in the basement is satisfactory.
It has been noted that there was once plans to expand the existing facility. One method that has
been considered to accomplish this expansion is through the addition of a second level to the
existing facility. If this were the case, the existing equipment could be relocated to the new roof
surface at minimal expense. Alternatively, the condensing unit could be ground mounted in a
suitable location and would not require relocation. This would leave only the ventilation unit to
be relocated.
This scope of work would include the following:
• Appropriately configured Fan Coil Units (FCU) zoned to accommodate the present day
building zoning requirements.
• Refrigerant piping located above the corridor ceilings to serve branch selector boxes and
FCU's.
• Roof mounted condensing units.
• Roof mounted dedicated outside air unit.
• New insulated sheetmetal supply and exhaust ductwork to provide proper ventilation
throughout the main level.
• Redesign of building exhaust system.
• Integrated temperature controls.
• Demolition of all obsolete HVAC system elements.
We have based this recommendation on the following benefits:
• Less first cost over a comparable Variable Air Volume (VAV) system with hot water re-
heat.
• Less equipment intensive.
• No boiler and related periodic boiler inspections.
• No pumps.
Page 4 of 6
• Excellent energy efficiency.
• Ability to provide good zoning and space temperature control.
• Integrated temperature control system included with the system.
• Ability to phase the work so as to maintain an acceptable level of space comfort during
construction. (The existing system may be able to remain operational during
construction.)
• Reduction in the size of replacement ductwork since it only delivers ventilation air.
• Increased floor space in the basement. The existing air-handling unit room can be
repurposed once the existing equipment is demolished.
ENERGY EFFICIENCY
The proposed VRV system will result in better efficiencies and less operational costs over the
existing chilled/hot water multi-zone HVAC system. A VRV system was installed in Belair
Elementary School in Jefferson City, Missouri as part of a 2011 renovation of this building. The
VRV system (with dedicated outside air units) replaced large multi-zone air-handling units
serving the building. The original system was very close to the system presently serving the
Police facility.
Bob Weber, Facilities Director at Jefferson City Public Schools, reported that the utility bills for
this building were reduced by approximately 33 percent following the installation of the new
VRV system and related upgrades. As an additional benefit, the old mechanical spaces were
repurposed into usable space following demolition of the obsolete equipment.
Statistical data for various other projects compiled by one of our manufacturer's representatives
support these savings. It is their assertion that a VRV system will result in utility billings in the
$1.00 per square foot range, or in some cases less. The reason that VRV systems can realize
this degree of efficiency is that they are most efficient at "part load" conditions, rather than at
maximum load conditions. Typically, a HVAC system is operating at somewhat less than its
maximum capacity. (i.e. a "design" day) A graph included at the end of this report shows
various HVAC system types, and how they compare at various load conditions. Only water
source heat pumps exceed VRV system efficiencies, but only as they each approach full load
conditions. But again, VRV excels at the part load conditions where all HVAC systems normally
operate.
We have included two examples at the end of this report that show VRV systems retrofitted in
the High School at Fredricktown, Mo and Bayless High School in St. Louis, Mo. Each of these
examples show a drastic improvement in operating costs over the system that was replaced. In
the Bayless High School example, it should be noted that they are now heating and cooling the
building for slightly less than they were paying for heating only prior to the upgrade.
The operation of a police facility is on a 24/7 schedule, whereas the school examples noted
above are largely unoccupied during the night, weekends and holidays. In this case, one could
expect a somewhat higher operational costs since the building cannot be placed into an
"unoccupied" mode of operation during those periods. However, we anticipate that due to the
increased equipment efficiencies and correction of the excessive exhaust air condition that the
City will see an appreciable reduction in energy usage.
