UVM UTILITY SYSTEM MASTER PLANNING IDEA CONFERENCE International District Energy Association Sal Chiarelli, Director of Physical Plant, UVM February 2006

A Little Bit About UVM 9,000

Dudley Davis Student Center

Physical Plant IDEA 2006

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What Are Some Of Today’s Issues The growth on campus Energy costs Systems are outdated and obsolete Chilled water is not centralized Air conditioning is an expectation Utilities are critical for Research System reliability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

Physical Plant Operating Budget FY05- $25.2 Million

Sightlines Database Average: $6.70 /GSF Institution Shown: Duquesne University Indiana University Pennsylvania State University Rensselaer Polytechnic Institute Rutgers University Southern Methodist University Tufts University University of Denver University of Massachusetts Wesleyan University

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

Efforts Pay Off (So Far)

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 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 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 Summary
