1.0 INTRODUCTION
1.1 Introduction
This Utility Master Plan was conducted by Burns & McDonnell, Inc. for the purpose of evaluating utility
infrastructure, design standards, and future campus growth for Texas A&M University (“the University”
or “TAMU”). This effort was concentrated on updating the 2012 Utilities and Energy Master Plan to
provide recommended improvements and conceptual designs for projects that will allow the University to
meet their future utility needs reliably while ensuring cost effective stewardship of utility infrastructure.
This study presents an updated Utility Infrastructure Program Plan, the outcomes of the analyses
conducted for the central plants, demand side management, and comments to the existing design
guidelines.
Improvement options, modifications, and upgrades have been evaluated using accepted fundamentals of
engineering and practical considerations of existing conditions, constructability issues, and financial
impact. Each recommendation is provided with a narrative description of the proposed design strategy,
estimated construction costs, general arrangement drawings, and life cycle cost analysis, where
applicable.

2.0 EXECUTIVE SUMMARY
2.1 Purpose
The purpose of this study is to identify operational and functional issues regarding the existing utility
infrastructure. A plan to effectively meet the future growth needs of Texas A&M, complete with project
capital costs, schedules of implementation, and general arrangement drawings, has been developed.
Potential improvements are evaluated based on first cost, life cycle cost, reliability, and redundancy,
where applicable. This study includes an analysis of thermal (chilled water (CHW), heating hot water
(HHW), and domestic hot water (DHW)) and civil (domestic water) utilities. A selection of steam
distribution systems were also inspected, with a focus on evaluating the future distribution of steam for
process lab applications, such as autoclaves. Contained within this executive summary are the
recommended improvements, by system, for Texas A&M utilities over the study term. Payback periods
are defined in terms of simple payback, unless otherwise noted. Expected project life assumes
maintenance in accordance with manufacturer’s recommendations and feedback from University
personnel. All capital costs are in today’s dollars, unless otherwise noted.
2.2 Primary Goals
The primary goal of the study is to allow for the University to efficiently, reliably, and cost effectively
meet future utility needs that accompany growth on the East and West campuses of Texas A&M
University. To accomplish this, the study prioritized several objectives, including to:
• Review and compile design information for the existing utility infrastructure.
• Coordinate expected utility system growth needs to align with projected growth on campus.
• Develop a plan to meet the short and long term utility needs of the campus with discreet projects
and schedules.
• Provide a review of the production Design Guidelines to ensure the selection of robust and
reliable components for future utility system improvements.
• Project changes to the University’s greenhouse gas emissions resulting from chiller and hot water
boiler operation due to the expected campus growth at a summary level.

2.3 Overview of TAMU Utilities and Energy Services (UES)
The Utilities & Energy Services (UES) Department at Texas A&M University, which includes over 220
staff members and $85 million in annual billing, provides comprehensive utilities and energy
management services for the entire University, managing seven utility plants, serving over 800 buildings,
30 million gross square feet of facilities, and close to 80,000 faculty, staff, and students engaged in
research and teaching activities. The utility systems at the University have operated continuously longer
than any other in the region, with on-site power generation since 1893 to meet Texas A&M University
requirements. UES also manages one of the largest and most sophisticated Building Automation Systems
in the world, with over 500,000 monitoring and control points to regulate temperature, humidity, air and
water flow, and lighting in campus facilities.
The utility infrastructure at TAMU has an estimated replacement value of $1.5 billion which includes
the production, distribution and processing of electricity, water, sanitary sewer collection and treatment,
storm drainage, solid waste and recycling services, together with building demand-side management. The
figure below highlights the various scopes of services provided by UES.
Figure 2-1: UES Responsibility Overview
Additionally, UES has undertaken the following Energy Initiatives:
• Comprehensive Building Utility Metering
• Combined Heat and Power (CHP)
• $30MM invested in Energy Consumption Reduction Projects over six years

• Energy Stewardship Program
• Energy Performance Improvement (EPI) Program
• Energy Action Plan (EAP) 2020
• Chilled Water Optimization Program
• Utilities & Energy Design Standards
• Utilities & Energy Master Planning
• Utility Infrastructure Capital Investment
These initiatives have further supported UES’s stated mission of Providing world class service through
the production, delivery, and management of safe, reliable, and efficient utility and energy systems,
effectively stewarding university resources and the environment.
2.4 Systems Improvements Overview
The following sections describe the projects recommended for implementation through the end of the
study period. The projects represent capacity upgrades, efficiency improvements, end of life
replacements, new construction, and other plans that will improve the delivery of utilities to the TAMU
campus. The “Priority” or “First Project Priority” date indicates year of implementation or the first year
that the particular category of project has been identified for implementation if multiple projects of that
type are planned. All project costs are presented in 2017 dollars unless otherwise indicated.
2.5 Chilled Water Systems Improvements
The following equipment upgrades, renewals, and additions are recommended over the next 20 years to
maintain reliability, N+1 redundancy at the plant level and to provide life cycle cost savings.
2.5.1 Capacity Replacement/Renewal
Over the course of the next 20 years, several chilled water producing machines within the Texas A&M
University fleet will have exceeded ASHRAE and/or industry recommended service life. Chillers that
exceed their service life are recommended for replacement during the fiscal year in which the service life
is exceeded. This practice reflects the technically recommended date of replacement, which is
summarized in Table 6-3. However, project funding and available capital resources, as well as serviceable
condition of the equipment may dictate that some project dates be shifted and/or the scope of that
replacement should be modified. The actual date of replacement projects are included in Table 6-7 and
Table 6-8.

2.5.2 Capacity Additions/Upgrades
As both East and West campuses continue to experience significant growth, the chilled water system will
experience corresponding increases in demand that will require the installation of additional chilled water
production equipment. New equipment is recommended for installation within physical expansions of
SUP1 and SUP3 and within a new plant (SUP4) on West Campus. The recommended dates of
implementation for capacity additions are included in Table 6-7 and Table 6-8.

2.5.3 Heat Pump Chiller Addition to SUP1
Install a nominal 1200 ton Heat Pump Chiller to serve the West Campus Chilled Water system. The
addition of the heat pump chiller will allow waste heat generated during the production of chilled water,
which is normally rejected through a cooling tower, to be recovered and used to produce “free” heating
hot water. This technology has already been utilized successfully at SUP2, resulting in significant savings
to the University due to reduced boiler natural gas consumption, makeup water, and chemical treatment
water while also reducing the campus carbon footprint. The payback period listed below is reflective of
escalated natural gas and electrical costs.

2.6 Condenser Water Systems Improvements
The following equipment upgrades, renewals, and additions are recommended over the next 20 years to
maintain reliability and N+1 redundancy at the plant level.
2.6.1 Capacity Repairs/Upgrades
Many of the existing cooling towers on campus have served the heat rejection needs of the chilled water
production equipment for a number of years, often through multiple upgrades and/or replacements of the
equipment that the cooling towers serve. As the cooling towers have aged, performance has deteriorated,
even stranding chilled water production capacity at the CUP, as the condition of existing towers CT13
2017 UES Master Plan Report Revision 1 Executive Summary
Texas A&M University 2-5 Burns & McDonnell
and CT14 can no longer support the chillers they serve. These towers require repairs to return the towers
to nameplate capacity and to provide maintenance for the prevention of further degradation. Further, as
chilled water production equipment capacity is upgraded, it can be cost effective to upgrade existing
towers in lieu of installing new capacity. An inspection of the existing towers was performed to verify the
condition and capacity of the cooling towers and to evaluate their potential for expansion/upgrade. The
recommended dates of implementation for cooling tower repairs and upgrades are included in Table 7-3
and Table 7-4. The year in service for all projects noted as “REPAIR-MAINT” was estimated with the
assumption that all projects would be undertaken linearly starting in 2019 and be completed by 2022.
These dates can be shifted pending funding availability and to accommodate plant operational needs.
Programmed cost...…….…...…$2,546,000 First Project Priority……………2018
2.6.2 Capacity Additions
As both East and West campuses continue to experience significant growth, the chilled water system will
experience corresponding increases in demand that will require the installation of additional chilled water
production equipment. All additional tons of installed chiller capacity will require the support of
additional heat rejection capacity. New cooling towers are recommended for installation within physical
expansions of SUP1 and SUP3 and at a new plant (SUP4) on West Campus. The recommended dates of
implementation for capacity additions are included in Table 7-3 and Table 7-4. The costs for
implementation of these cooling tower addition projects are included in the chilled water additions
projects summarized in Table 6-7 and Table 6-8.
2.7 Heating Hot Water Systems Improvements
The following equipment upgrades, renewals, and additions are recommended over the next 20 years to
maintain reliability and N+1 redundancy at the plant level.
2.7.1 Capacity Replacement/Renewal
Over the course of the next 20 years, several heating hot water producing machines within the Texas
A&M University fleet will have exceeded ASHRAE and/or industry recommended service life. Boilers
and heat exchangers that exceed their service life are recommended for replacement during the fiscal year
in which the service life is exceeded. This practice reflects the technically recommended date of
replacement. However, project funding and available capital resources, as well as serviceable condition of
the equipment may dictate that some project dates be shifted and/or the scope of that replacement should
be modified. The actual date of replacement projects are included in Table 8-3.

2.7.2 Equipment Additions/Upgrades
As both East and West campuses continue to experience significant growth, the heating hot water system
will experience corresponding increases in demand that will require the installation of additional heating
hot water production equipment. New equipment is recommended for installation within physical
expansions of SUP1 and within a new plant (SUP4) on West Campus. The recommended dates of
implementation for capacity additions are included in Table 8-3.
Programmed cost...…….…...…$5,535,000 First Project Priority……………2019
2.8 Steam Systems Improvements
Steam is generated at the Central Utility Plant (CUP) on East Campus via three boilers, B1, B2, and B12.
This steam is largely utilized in various equipment within the CUP, however a small portion of
intermediate pressure steam is also distributed to a limited number of buildings on East Campus to serve
process loads, such as sterilization autoclaves. Over the years, the condition of distribution infrastructure
has deteriorated to the point that, given the small quantity of equipment that consumes steam, the retrofit
or replacement of that process equipment has become more cost effective than repair/replacement of the
distribution infrastructure. In addition, the condition of the distribution system has, in places, presented
safety concerns that UES has recognized the need to address. The improvements listed in Section 9.5 are
recommended for implementation within the next 5 years, which will largely eliminate the distribution of
steam to campus, except for supply to the Chemistry complex and Zachry Building as the largest steam
consumers. These costs are further delineated in Table 9-7.

2.9 Domestic Cold Water and Fire Water Systems Improvements
Campus domestic water supplied by wells is stored in ground tanks at the Luza Lane transfer pump
station, which then moves water to the F&B ground storage tanks for use by service pumps pumping into
the campus distribution system.
The domestic water model results identified some sections of piping that may experience elevated flow
velocity and excessive head loss. These sections of piping are recommended for further analysis to
2017 UES Master Plan Report Revision 1 Executive Summary
Texas A&M University 2-7 Burns & McDonnell
determine the extent of needed future replacement, if any such need exists. The model results also
indicated that additional system installations may be required to improve the predicted low fire flow
pressure in the western edge of the system as shown in Appendix I and Table 11-8. However, the
buildings in that area of campus are currently provided with fire protection from alternative sources and
thus the system is not considered deficient. Improvements are recommended in the future and as budget
allows to support potential future expansion that may occur in that area. Since this project may not be
required pending future campus development, programmed costs have not been included in the overall
project totals.
Programmed cost...…….…...…$2,820,000
Sections of new distribution pipe are recommended to be replaced with larger pipe in four locations as
shown in Appendix I. These improvements, which total nearly 10,000 LF on both the East and West
Campuses, should be performed prior to the construction of the associated adjacent buildings which they
will ultimately serve.
Programmed cost...…….…...…$2,040,000 First Project Priority……………2037
2.10 Domestic Hot Water Systems Improvements
Domestic hot water on campus is generated both locally and centrally. Central domestic hot water is
generated at the CUP and SUP3 and distributed to approximately 65 buildings on East Campus. The
University’s strategy to manage future domestic hot water on East Campus is the same as West Campus,
and therefore all new buildings will be supplied with local heaters to manage their domestic hot water
needs.
The two CUP heat exchangers (DHWHX-1 and DHWHX-2) used to supply domestic hot water are not
large enough to provide the recommended N+1 capacity and there are occasions when the University is
forced to run both heat exchangers simultaneously. Additionally, the domestic hot water boilers in SUP3
(DHWB301 and DHWB302) are in too poor condition to provide reliable service and are recommended
for replacement within the next 5 years.
2.10.1 Capacity Upgrades
To address redundancy and reliability concerns at SUP3 with a robust solution, the replacement of
existing domestic hot water boilers DHWB301 and DHWB302 is recommended. To address redundancy
and reliability concerns at the CUP, the possible repurpose of existing HHW HX-1 to the production of
2017 UES Master Plan Report Revision 1 Executive Summary
Texas A&M University 2-8 Burns & McDonnell
domestic hot water is recommended, pending further investigation into materials of construction for
compliance with safety codes.
Programmed cost...…….…...……$1,250,000 First Project Priority………………2018
2.11 Combined Heat and Power Systems Improvements
Much of the existing CHP system was installed in 2011, therefore, given proper maintenance, most major
components of the system should remain in serviceable condition for the duration of this study. Table
13-2 lists recommendations for major service intervals based on hours of operation. Continued
inspections of major equipment are recommended based on service life, performance, and routine
maintenance reports.
For planning purposes, it is recommended that TAMU carry budgetary reserves for the major
maintenance and capital replacement items described in Table 13-2, which may be required following
inspections of major equipment. Additionally, should the University determine that a second CHP system
may provide and economic or reliability benefit to campus, it is recommended that TAMU carry
$150,000 for general studies to further examine those benefits, potential restrictions, and possible
solutions for that option. Since this is placeholder for a study that will be conducted at an undetermined
date in the future, programmed costs have not been included in the overall project totals.
Programmed cost...…….…...…$150,000
2.12 Thermal Distribution Systems Improvements
As the campus grows, the thermal distribution systems will require extensions to serve the new areas of
building expansion on campus. The costs below reflect new distribution projects only and do not include
existing piping replacements.
Programmed cost...…….…...……$19,000,000 First Project Priority………………2019
2.13 Utility Plant Controls Upgrades
Modern and efficient controls are the foundation of a reliable utility production system. The control
systems at the CUP, SUP1, SUP2, SUP3, and the Domestic Water Plant are aged and will require
software and hardware upgrades in the near term to maintain reliable utility service.

2.14 Moore-Connally Building (MCB) Improvements
The Moore-Connally Building (MCB) is located approximately 1-mile northeast of the East Campus of
the Texas A&M University College Station campus. This 7-floor building serves as an administrative
office facility where many of the meetings that guide the future of the campus are held. The adjacent
utility building houses equipment to directly serve the heating and cooling needs of the MCB. The
existing chillers and cooling towers have aged beyond their useful service life and are in need of
replacement in the near term.

2.15 UES Department Building Development
The programming and planning process used for the new UES administration building produced multiple
floor plan and site plan options. Additionally, the process evaluated potential construction methods and
exterior aesthetic options. Each option considered a phased development of the site with the
administration building as the initial phase and the distribution building as a secondary phase.
While the master planning process incorporated full build-out options for the site, the programming and
estimated cost of construction do not incorporate the distribution building development.

2.16 Greenhouse Gas Emissions
Since 2002, Texas A&M has reduced energy consumption and GHG emissions related to campus
operations through an aggressive energy consumption reduction program. Going forward, it is assumed
that the University will continue the practice of reducing energy consumption in existing buildings and
setting high efficiency standards for future construction. The assumed future efficiency improvements for
existing and new buildings are included below in Table 2-1.

Texas A&M University 2-10 Burns & McDonnell
Table 2-1: Utility Improvement Recommendations
Building Category % Reduction Term
Existing 1.5 Annually
New 1 Annually
Non-Energy 1.5 Annually
Based on the Demand Side Management (DSM) opportunities on campus, it is assumed that the GHG
output associated with the energy consumption at existing buildings will be reduced by 1.5% annually,
which result in a total average GHG reduction of over 25% in the existing buildings by the end of the
plan. For the same 20 year period, the average carbon output of new space growth will be reduced by a
proposed 1% annually. This will result in new space that is over 17% more carbon efficient at the end of
the plan as compared to the beginning of the plan. Overall, this will reduce the total average carbon output
for new space for the 20 year period by over 8.5%. This is an aggressive target and will be achieved by a
combination of demand side reductions in the buildings and a more efficient carbon content of purchased
energy.

2.17 Demand Side Energy Management
Texas A&M has made significant reductions in Energy Use Intensity since 2002.
Figure 2-2: Campus GSF vs Energy Consumption
Figure 2-3: TAMU Energy Use Intensity Improvements
2017 UES Master Plan Report Revision 1 Executive Summary
Texas A&M University 2-12 Burns & McDonnell
The figures above show campus growth, campus energy consumption, and annual EUI over nearly two
decades. It can be seen in Figure 2-3 that significant reductions in EUI have been made since 2002.
As a part of this Master Plan, an analysis was performed and recommendations made regarding future
Demand Side Management (DSM) initiatives on campus. In addition to the DSM strategies already being
undertaken by TAMU, three immediate areas of opportunity on campus were identified to affect building
energy usage and utility demands.
2.17.1 Air-Side Heat Recovery
TAMU campus standards and state energy codes typically require heat recovery to be installed on
building exhaust air during new construction. This is to transfer heat between the exhaust and outside
airstreams and offset heating and cooling energy in the AHUs. Historically, TAMU has struggled to
maintain and operate the existing heat recovery systems. This is similar to most college campuses and is
due to both the complexity of the systems and cumbersome maintenance requirements. On average
across the campus, 35% of the systems are currently abandoned or have malfunctioned. This study
performed and analysis of commercially available heat recovery technologies and determined a strategy
for implementing the most life cycle cost effective and safe systems based on building use and size.
Although enthalpy wheels are by far the most effective technology and should be used in many cases if
maintainable, they are not always appropriate due to the possibility of cross-contamination between the
airstreams. Fixed plate heat exchangers are recommended for smaller applications. For larger airflows
where either the exhaust and outside airstreams are far apart or where cross-contamination presents indoor
air quality hazards, run-around glycol coils are recommended.
2.17.2 Obsolete Siemens Components
Due to the obsolescence of older Siemens BAS components in over 200 buildings on campus, and the
functional limitations caused by that obsolescence, BMcD recommends a phased approach to replace the
outdated and limiting components across the campus. TAMU is having more and more difficulty
sourcing and stockpiling parts for failing hardware, because Siemens does not manufacture or support
those obsolete components. Several of the typical controllers on campus have not been supported for
many years. The replacement of the obsolete components will naturally result in energy savings in the
buildings, due to elimination of outdated pneumatic controls and use of occupancy feedback.
Furthermore, TAMU will use lessons learned from their in-depth knowledge of Siemens controls on
campus to optimize the sequences of operation in the replaced controllers. The total cost of these
upgrades will be spread out over two project phases.

2.17.3 Laboratory and Fume Hood Energy
This report includes an analysis of the energy impact of the fume hoods and associated labs on campus in
an effort to frame the potential for lab energy savings. BMcD built sample lab energy models, informed
by sample building walkthroughs, to quantify typical energy savings for incremental investments in lab
energy efficiency. The results of the analysis are as follows:
1. The 1,712 fume hoods on campus are estimated to cost as much as $3.1 Million dollars to operate
annually.
2. Sampled labs have significant opportunity for energy savings (40-65%).
3. Investment should be focused first on the high ROI opportunities like setpoints, occupancy
sensors, and minimum fume hood airflow modifications.
4. Conversion of labs/hoods to VAV may require significant investment in infrastructure.
5. Labs have to be analyzed individually to avoid wasting money on technologies that won’t
actually save money (airflow). Depending on fume hood density in a lab, modifications to the
hoods may cease to show a return on investment.
This report includes a recommended strategy consisting of detailed laboratory inventories,
evaluation/modeling of potential energy savings, grouping of labs by system type, potential savings, and
investment, and categorizing the labs for prioritized investment. The goal is to address the high-ROI labs
first, using tools and techniques already in place (like the EPI program) and then moving on to the labs
that require capital investment to achieve deep energy savings. The development of this program and
approach should consider the planned replacement of the obsolete Siemens controls components to
minimize cost and schedule impacts.
