Background
• UVM’s Infrastructure:
– Centralized heating system
– Localized cooling system
– Purchased power with over 125 meters
– Limited investment in infrastructure
What Are Some Of Today’s Issues
•
•
•
•
•
•
•
The growth on campus
Energy costs
Systems are outdated and obsolete
Chilled water is not centralized
Air conditioning is an expectation
Utilities are critical for Research
System reliability
Physical Plant Goals
• Convince UVM’s Administration to invest more in
infrastructure to meet the needs of the future
• Develop a realistic utilities plan
• Capitalize on planned construction/excavation
• Reduce incremental utilities costs
• Reduce downtime of utilities
Some Other Objectives

•
•
•
•
Invest in the future - UVM will be here forever
Develop chilled water system
Develop Combined Heat and Power (CHP)
Maximize the use of the steam system
Minimize demand charges from local utilities
Invest in distribution and central systems.
Design for contingencies
Use fuel to the maximum to benefit the environment
Use systems as an educational model
Current construction creates opportunities
Campus-Wide Peak Electrical
Demand:
• Current Year (Yr 2003)
• Projected Year (Yr 2010)
Over 35% increase
11.5 MW
16.0 MW
Financial Outlook
• 2003 Energy Cost
~ $10 Million
(Fuel Oils, Natural Gas, Water and Electric)
• 2006 Projected Energy Cost
~ >$13-15 Million

Tri-generation Vision
• Generate energy for heating, cooling
and electricity from a central source

Cooling System
• Our Approach:
– Build centralized system in multiple phases to lower
costs
– Expand plant in the future to provide cooling
for new as well as existing buildings
Major Advantages of Centralized
Cooling System
– Lower life cycle costs
– Operating cost reduction of about 30%
– Allows optimum system configuration for the CHP
System
– Reduction of peak electrical power
– Substantially lower costs for the future
– Less construction time for future buildings
– Allows cooling of historical buildings
– Lower emissions - better environment-regionally
Combined Heat and Power (CHP)
•
Proposed CHP is for a 4.5 MW unit
Major benefits of Combined Heat and Power
– Increase overall efficiency
– Reduces overall emissions
– Helps local electric company as their power purchase
need is reduced.
– Protects UVM and city from potential brownouts
– Has a potential to reduce annual energy costs to
UVM by $2.0 million dollars
– Offsets the need for the future steam boiler

Our relationship with UVM
• Involved since the early seventies
– Created a central heating plant
• UVM is different than most facilities
– As the university will be here for
hundreds of years, the infrastructure
decisions are based on vision rather
than just bean counters
Site Utilities Analysis and Design
• Heating site distribution system
analysis and design
• CHW systems master plan
• Cogeneration analysis
• Comprehensive Utility Master Plan
• Chiller plant expansion
Why comprehensive utility
master planning?
• Infrastructure includes over fifteen
utilities for a campus
• Most of the time communication
between different consultants designing
their specialty utility does not exist
• Relocation of relatively newly installed
utilities for a new building is quite
common
Site Utilities
• High voltage
electrical
• Chilled water
• Low voltage
electrical
• Fuel oil
• Emergency Power
• Communication &
life safety
• Condenser water
• Sanitary Sewer
• Storm water
• Fire water
• Natural gas
• Domestic water
• Nitrogen
• Domestic hot water
• Steam/hot water
• Laboratory waste
Problem:
• Typically there is little or no
coordination between campus
projects and campus utilities
• Each project is performed in a
“vacuum” without consideration of the
overall campus master plan
• In most cases a master plan does not
exist or is not implemented
Project Goal:
1. Incorporate all individual utility maps
into a single electronic site utility
map
2. Map to be used for:
–
–
–
–
Mapping existing conditions
Estimating remaining useful life
Identify areas of deficiencies
Planning future utilities expansion
based on anticipated future campus
growth

Storm Sewer
Sanitary Sewer
Water – Domestic, Fire Protection, Irrigation
Natural Gas
Mechanical: WM Group Engineers
• Steam & Condensate
• Chilled Water
• Fuel Oil
Campus Utilities (cont’d)
Electrical: UVM, BED, Wolbach, WM Group
• Power Distribution
• Emergency Power
• Lighting
Telecommunications: UVM - Telecom
• PBX
Controls: UVM - PPD
• Building Management Systems
• Security/Fire
Approach:
1. Receive latest background from UVM
- Based on Lockwood map
2. Collect latest existing utility info
3. Generate working background
- Create presentation standard
(i.e. scale, view ports, title block, etc.)
- Create layer convention
(i.e. layer designations, color, text
height, insertion points, etc.)
Approach (Cont’d)
4. Create FTP site
5. Each utility accesses background (via
FTP site) to create map of utility
based on existing, demo, proposed,
and future.
6. WM Group to act as “Quarterback” to
coordinate all consultants to create a
“Master Utility Plan”
7. All consultants to update drawings
based on their latest surveys
Approach (Cont’d)
8. Identify condition, remaining life, etc.
of the existing systems
9. Prepare a report of the existing
conditions
10. Living document to be updated as
required
11. Expandable to include GPS
coordinates and site specific
information
Distribution Phasing
Summary
• Communication between the various
utility consultants is a key to
infrastructure planning success
• You need to have a “Quarterback” from
New York with a Type A personality to
lead the team!
• Technology is changing and the use of
GPS with infrastructure planning is a
must for all Universities
