EXECUTIVE SUMMARY
The Continuous Commissioning®
(CC®)
1 process has been applied to the Gibb Gilchrist
Building. It is a three-story building consisting of offices, conference rooms, and
transportation laboratories, and is located on the West Campus at Texas A&M
University. The HVAC system is a single duct VAV system with pretreated outside air,
and incorporates three air handling units (AHUs) and one outside air handling unit
(OAHU). A Siemens DDC controls system operates all air handling units, pumps, and
terminal boxes.
CC began in this building on May 7, 2007. As of this report date, none of the five
recommended CC measures had been implemented. The CC measures recommended
included: 1) optimizing AHU discharge air temperature set point schedules, 2)
improving OAHU discharge temperature set point scheduling, 3) resetting terminal box
minimum flow at night, 4) programming valve spring ranges correctly for AHUs, and 5)
scheduling the building exhaust fan off during unoccupied periods.
The baseline energy use index (EUI) was 125.2 mBtu/ft2-yr. The baseline energy cost
index (ECI) was $1.666/ft2-yr. Because no CC measures had been implemented at the
time of submittal of this report, a savings analysis involving measured pre-CC and post-
CC data was not performed. However, based on simulation and engineering analysis, it
was estimated that implementation of the recommended CC measures would result in a
total savings of $15,000 per year. This would lower the EUI to an estimated 101.5
mBtu/ft2-yr, and would lower the ECI to an estimated $1.442/ft
2-yr. These values were
based on a rate of $7.347/mmBtu for chilled water, $9.735/mmBtu for hot water, and
$0.079/kWh for electricity.
Additionally, two main comfort issues in this building were investigated. One is that the
second floor felt humid to occupants when they first entered. When the stuck 100%
open chilled water valve on the first floor was fixed, this problem was resolved. The
other comfort issue is that occupants of offices on the west side of the building
complained of hot temperatures and significant variation of temperatures between
window, desk, and thermostat locations. Investigation results indicated that the room
temperature at the desk level was acceptable. The complaints were mainly due to direct
solar radiation on occupants. It is recommended to install and/or apply: internal or
external solar shading or window tint.

BACKGROUND
Continuous Commissioning is an ongoing process to resolve operating problems,
improve comfort, optimize energy use and identify retrofits for existing commercial and
institutional buildings and central plant facilities. The Energy Systems Laboratory,
which trademarked this process, has been under contract with the Physical Plant at Texas
A&M University since 1997 to systematically commission the campus buildings as
requested. During the time period since this began, more than 70 buildings have been
commissioned, resulting in energy savings to Texas A&M University of millions of
dollars. For the year 2007, 25 buildings (totaling 2.5 million square feet) have been
identified to be commissioned, including the Gibb Gilchrist Building. This building was
identified as a prime candidate for Continuous Commissioning due to its comfort
complaints, and because it had not previously been commissioned. Commissioning
began on April 7, 2007.
SITE DESCRIPTION
General Facility Description
Figure 1. Gibb Gilchrist Building.
Figure 2. Building location.
The Gibb Gilchrist Building, pictured above in Figure 1, was constructed in 1999 and is
located on the west campus of Texas A&M University (see Figure 2 above). It is one of
the buildings used by the Texas Transportation Institute (TTI), and consists primarily of
offices and conference rooms, with some transportation laboratories as well. The
building has three floors for a total area of 67,143 square feet. It is generally occupied
on weekdays from 8:00 AM to 5:00 PM, but also has some occupancy later in the
evening and on weekends.

General HVAC System Description
Mechanical
The chilled water system in the building utilizes one 20 hp, 470 gpm pump with VFD
run by EMCS control. Both the pump and the control valve are DDC controlled by
pressure differential. The piping system is two-way variable speed flow without bypass.
The heating water system utilizes one 7.5 hp, 215 gpm pump with VFD run by EMCS
control. Both the pump and the control valve are DDC controlled by pressure
differential. The piping system is two-way variable speed flow without bypass. A
summary of the building pumping information is shown in Table A-1 in the Appendix.
The HVAC system in the building is a single duct, variable air volume system with
terminal reheat, and consists of three air handling units and one outside air pre-treat unit.
The controls system is DDC and is powered by Siemens Apogee. The total design
maximum supply flow in the building is 63,820 cfm, of which by design 7,910 cfm is
outside air. The total design exhaust flow from the building is 4,040 cfm, and is
achieved with one exhaust fan. Tables A-2 and A-3 in the Appendix give an overview
of the air handling units and exhaust fans comprising the building HVAC system, with
their design information.
The lighting system in the building is comprised of T8 lamps on all floors, with motion
sensors in place in offices, but not in conference rooms.
Controls
The pre-CC operation of pumps brought the pumps on according to building demand.
The pumps and control valves controlled to allow the loop differential pressures to meet
their set points. The differential pressure set point for the chilled water loop was reset
between fixed limits according to a weighted average of AHU chilled water valve
positions from all AHUs and the OAHU. The differential pressure set point for the hot
water loop was reset between fixed limits according to a weighted average of terminal
box reheat valve positions and OAHU preheat valve position.
The pre-CC operation of AHUs maintained all of the units running at all times. Each
unit had different settings for normal, late, and later modes. All terminal boxes served
by each AHU were periodically sampled, and their heating and cooling demands and
damper positions were averaged with a weighted averaging function. Static pressure set
points for each AHU were raised or lowered between fixed limits according to average
terminal box damper position, and discharge air temperature set points were raised or
lowered between fixed limits according to average terminal box cooling demand. Zone
temperature cooling set points were between 73 and 76°F, while zone heating set points
were nearly all 70°F.
The pre-CC operation of the outside air handling unit attempted to utilize the unit to
temper the outside air somewhat before it was sent to the AHUs. The cooling
temperature set point was based on outside air dew point temperature, and the preheat
temperature set point was constant. The amount of outside air allowed to each unit was
regulated with pressure independent dampers in the outside air ductwork.

Energy and Comfort Baselines
The baseline energy usage for the building before CC occurred is summarized in Table
1. The baseline period chosen was from 1/1/06 through 12/31/06.

index (ECI) was $1.666/ft2-yr.
Several comfort complaints in the building were brought up at the time of
commissioning. The main issue was that offices on the west end of the building
reportedly experienced numerous hot calls on sunny afternoons, with large temperature
stratification between the window, desk area, and thermostat. In an attempt to combat
this problem, zone cooling temperature set points for offices with west facing windows
had been lowered to 73°F. While this helped, it did not completely solve the problem,
and in fact resulted in some cold complaints from occupants. Other comfort issues
reported were that the second floor was warm and humid relative to the first floor, and
that several other rooms throughout the building either were too cold or too hot for
occupant comfort.
CONTINUOUS COMMISSIONING ACTIVITIES
The Continuous Commissioning process involved a thorough evaluation of current
building conditions and operation, including field measurements, remote monitoring,
and control review. From the investigation performed, the causes of a number of
problems with comfort and energy efficiency in the building were identified. CC
measures have been recommended to aid in allowing this building to operate more
efficiently and to provide better comfort. Additionally, a retrofit opportunity and
maintenance issues that were noted during the CC process have been documented. The
sections that follow describe the conditions found in the building at the time of CC, the
CC measures recommended for improved building performance, and the results achieved
thus far in the building.
Continuous Commissioning Measures
A total of five CC measures have been identified through the CC process, including
AHU shut downs, improved AHU discharge temperature and static pressure set point
4
scheduling, better outside air control, improved differential pressure control of HW and
CHW systems, and terminal box control improvement, among others. These CC
measures are summarized in Table 2, with the level of priority and implementation status
of each as of the report submittal date. Detailed findings and explanations of the
measures follow.

CC1. Optimize AHU discharge air temperature set point limits.
At the onset of commissioning, each of the AHUs was programmed with demand based
resets on discharge air temperature and static pressure set points. Weighted average
cooling loops and damper positions of the terminal boxes served were calculated, and
these values were used to increase or decrease set points as needed.
The AHUs were scheduled to have different reset limits during Normal Occupancy,
Minimal Occupancy, and Hibernate/Essential Only modes. Table 4 shows the upper and
lower reset limits for each AHU at the time of commissioning during normal occupancy.
For other occupancy mode set points, see the Appendix.

It was recommended that the discharge temperature reset limit ranges on all of the AHUs
be expanded. It was recommended that an upper limit of 70°F be used. Since
dehumidification would take place at the OAHU, this high temperature would not be a
problem as long as terminal box cooling demand allowed it. Additionally, this would
have the advantage of when most or all of the boxes served were in heat, the primary
flow from the AHU used as minimum flow for each terminal box would essentially be
neutral air, thus saving cooling energy and reheat energy.
This measure had not been implemented as of submittal of this report.
CC2. Optimize OAHU 3-1 heating and cooling temperature set point scheduling.
The pre-CC operation of OAHU 3-1 had the unit preheat the air to a constant 50°F, or to
cool it to eight degrees below outside air dew point temperature, with lower and upper
cooling limits of 55 and 65°F, respectively. The OAHU was also programmed with a
static pressure set point of 0.4 in. W.G.
More energy efficient control of the OAHU set point temperatures was recommended
during commissioning. Figure 3 that follows shows the recommended control for the
OAHU.

It was suggested that the cooling and heating temperature set backs recommended for the
unit would allow it to operate more efficiently. Additionally, the proposed control
would allow all needed dehumidification to occur at the OAHU level.
This measure had not been implemented as of submittal of this report.

CC3. Reset terminal box minimum flow at night.
A significant amount of energy consumption in the building can be attributed to high
minimum flows at the terminal boxes. Because of ventilation requirements, these high
flows are sometimes necessary. However, during unoccupied periods, minimum flow is
not needed from the terminal boxes for ventilation purposes. It was therefore
recommended that a general scheduling be implemented, such that when each terminal
box switched to night mode, the minimum flow would be commanded to zero. Besides
saving energy, this measure would also help prevent the overcooling of rooms during
unoccupied periods, which should improve comfort conditions for occupants when first
arriving to their respective spaces.
This measure had not been implemented as of submittal of this report.
CC4. Program the AHU valve command values to reflect actual measured spring
ranges.
The spring ranges for each of the AHU valves were measured and compared with the
ranges in place in the PPCL programming at the onset of commissioning. Table 4 below
shows the results of this comparison.

As noted, two of the valves, those for AHUs 1 and 3, had recently been replaced as part
of the CC process, probably contributing to the differences in programmed and measured
spring ranges. It was noted that with the new valve on AHU 1, discharge air temperature
could not be maintained at its set point because the signal given the valve would not
fully open it.
It was recommended that the ranges given in the PPCL programming be updated for all
valves where this was needed in order to allow the valves to fully open and close. This
was also believed to have a preventive maintenance impact since the valves would not
be as likely to wear out as quickly if they were able to fully open and close. It was noted
that comfort would also be improved in some cases such as for AHU 1.
8
As of submittal of this report, the programmed spring range had only been corrected for
AHU 1, and the measure was still pending for the remainder of the units.
CC5. Schedule exhaust fan to cycle off during unoccupied periods.
At the onset of commissioning, the outside air handling unit, OAHU 3-1, was scheduled
off during unoccupied periods. However, the building restroom exhaust fan, EF-1,
remained on continuously. This created negative pressurization in the building, which
had the potential to cause humidity and mold problems in the building during periods of
humid outdoor conditions. To combat this problem, as well as to save energy, it was
recommended that the building exhaust fan be scheduled to shut down any time the
OAHU was off.
This measure had not been implemented as of submittal of this report.
Continuous Commissioning Results
Savings Analysis
Since no CC measures had been implemented at the time of submittal of this report, a
savings analysis involving measured pre-CC and post-CC data was not performed.
However, based on simulation and engineering analysis, it was estimated that
implementation of the recommended CC measures would result in a total savings of
$15,000 per year. This would lower the EUI from 125.2 mBtu/ft2-yr to an estimated
101.5 mBtu/ft2-yr, and would lower the ECI from $1.666/ft
2-yr to an estimated
$1.442/ft2-yr. These values are based on a rate of $7.347/mmBtu for chilled water,
$9.735/mmBtu for hot water, and $0.079/kWh for electricity.
Comfort Improvements
One of the primary objectives of Continuous Commissioning is to improve occupant
comfort levels in buildings. Some of the major comfort issues that this building
experienced before commissioning included hot complaints in west facing offices, more
humid conditions on the second floor than the first, and various hot or cold complaints
from occupants at other locations in the building. A maintenance issue that took place
during commissioning was to replace the chilled water valve on AHU 1. Prior to this,
the humidity levels on the first floor were much lower than necessary because the chilled
water valve was stuck 100% open and would not control, causing discharge air to be
cooled excessively. Humidity readings taken at multiple locations on the second floor
during the commissioning process revealed levels in the 50% range, which was
considered acceptable. However, due to the lower humidity levels on the first floor, the
second floor felt humid to occupants when they first entered. Now that the first floor
valve has been controlling properly, this “comfort complaint” has become a non-issue.
The various other comfort problems noted throughout the building were related to
excessive computer equipment for rooms or occupant preferences. Some HVAC
renovation has already been identified and has begun to provide supplemental cooling to
a server room and to provide individual control to some other rooms with unique needs.
9
A few additional maintenance items were identified during the commissioning process
that aided individual room comfort in some cases.
As previously noted, the major source of comfort complaints in the building at the time
of CC came from offices on the west side of the building whose occupants complained
of hot temperatures and significant variation of temperatures between window, desk, and
thermostat locations. An investigation was performed regarding this issue. It was found
from the field measurement data that the room temperatures at the desk level were
generally consistent with the temperature at the thermostats located indicating solar
radiation is the reason of discomfort for occupants. There are several options to reduce
solar radiation:
(1) Internal shading/solar screen. There are retractable, single or dual shades,
motorized or manual operational solar screens available on the market.
(2) Window tint. It would reduce some of the solar radiation into the offices,
thereby improving comfort conditions.
(3) External shading. These screens can be made light enough to allow occupants to
see out the windows, but have the advantage of absorbing much of the solar heat
before it reaches the windows, allowing the windows to remain cooler, and
thereby helping to maintain a more consistent indoor air temperature in the
offices.
MAINTENANCE ISSUES AND RETROFIT OPPORTUNITIES
Observed Maintenance Related Issues
During the CC process several maintenance-related issues have been observed that
potentially waste energy, cause comfort problems, and sometimes prevent certain CC
measures from being implemented. In order to improve building comfort and maximize
potential energy savings, it has been recommended that these issues be addressed. These
issues are summarized in Table 5 with priorities and implementation status as of the
report submittal date.

Energy Retrofit and Capital Improvement Opportunities
No energy retrofit or capital improvement opportunities were identified during the
Continuous Commissioning Process.
CONCLUSIONS
The Gibb Gilchrist has been a part of the A&M system since 1975. Comfort problems in
the building and the fact that commissioning had never been performed in the building
made it a good candidate for Continuous Commissioning. Thus far none of the five
recommended CC measures has been implemented in the building. It was predicted that
implementation of the proposed CC measures would save $15,000 per year. After
complete implementation of these measures, better energy efficiency will occur in the
building, as well as an increase in the productivity of occupants who will be more
comfortable in their working environment. A number of maintenance issues have been
identified throughout the commissioning process, a majority of which have been
corrected. It is highly recommended that the pending maintenance issues be resolved
and the pending CC measures be implemented as quickly and as completely as possible
to maximize the value of the Continuous Commissioning of this building, and most
importantly, to maximize energy savings and comfort levels in the building. In this way,
the Texas A&M University campus can move forward in its quest for energy efficiency,
and the Continuous Commissioning process will have been beneficial in aiding in this
endeavor.
