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• The growth on campus• Energy costs• Systems are outdated and obsolete• Chilled water is not centralized• Air conditioning is an expectation• Utilities are critical for Research• System reliability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) 11.5 MW

• Projected Year (Yr 2010) 16.0 MW

Over 35% increase

Financial Outlook • 2003 Energy Cost (Fuel Oils, Natural Gas, Water and Electric)

~ $10 Million

• 2006 Projected Energy Cost ~ >$13-15 Million

Tri-generation Vision • Generate energy for heating, cooling

and electricity from a central source

Creating and Sharing The Vision

• Administrative Hearings/Meetings• Board Presentations• Using Visuals • Identifying Potential Losses (risk assessments)

• Long Term Outlook• Environmental University

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

– 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

Major Advantages of Centralized Cooling System

Combined Heat and Power (CHP)

• Proposed CHP is for a 4.5 MW unit

– 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

Major benefits of Combined Heat and Power

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

• Low voltage electrical

• Emergency Power

• Communication & life safety

• Natural gas

• Nitrogen

• Steam/hot water

• Chilled water

• Condenser water

• Fuel oil

• Sanitary Sewer

• Storm water

• Fire water

• Domestic water

• Domestic 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

Campus Utilities: Civil: Krebs & Lansing• Storm Sewer• Sanitary Sewer• Water – Domestic, Fire Protection, Irrigation• Natural Gas

Mechanical: WM Group Engineers• Steam & Condensate• Chilled Water• Fuel Oil

Electrical: UVM, BED, Wolbach, WM Group• Power Distribution• Emergency Power• Lighting

Telecommunications: UVM - Telecom• PBX

Controls: UVM - PPD• Building Management Systems• Security/Fire

Campus Utilities (cont’d)

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.)

4. Create FTP site5. 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

Approach (Cont’d)

Distribution Phasing

• 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
