Campus Facility

F i n a n c i a l C o n s u l t i n g S e r v i c e s

Client Profile

• Large domestic university• Multiple energy demands:

– Electricity– Steam heating– Chilled water loop

• Diverse resource mix including on-site generation, chillers, boilers, third party power and natural gas contracts

Engagement Objectives

• Reduction of client energy costs• Client tutorial on energy cost drivers• Implementation of energy cost

management theory and practice• Development of energy cost

management as a client strategic objective

Energy Cost Model

• Overview of energy sources and uses• Information required for analysis

– Equipment technical data (annual)– Contract pricing data (monthly)– Operating load and availability data

(hourly)

• Model calculation methodology• Program implementation

Energy Sources and Uses

Information Requirements

• Equipment technical specifications– Gas turbines, steam turbines, chillers,

boilers– Capacity, efficiency, availability

• Contract pricing and delivery terms– Utility energy contracts– Natural gas delivery contracts

• Operating load and availability data

Equipment Technical Data

Contract Pricing Data

Operating Load Data

• Energy diagram input• Campus 1 and Campus

2• Non-chiller electric (MW)• Cooling required

(tons/hr)• Heating load (kpph

steam)

Equipment Availability Data

• Energy diagram input• Campus 1 and Campus

2• Cogen (GT) Availability• Cogen (ST) Availability• Chiller Availability• Boiler Availability

Model Calculation Methodology

• Determines possible resource mixes to meet prescribed loads (electric, heating, chilling)

• Many individual scenarios are generated– Energy deliveries by resource– Total scenario cost determination

• Scenario evaluation and cost ranking

Model Demonstration

• User-oriented

• Diagram input panel

• Graphical results

• Calculation details

Program Implementation

• Demonstration of model and capabilities to client staff

• Refinement of input data• Training of client staff in model

functionality and application to practical energy resource management procedures
