## Utility Monitoring System Overview

- AH&MA Annual Conference & Leadership Forum
- April 5, 2001
- Chicago, IL
- Brian Burke, CEM
- Energy Manager

## Overview

- Hyatt Resource Management
- Value of Energy Accounting
- Utility Monitoring System (UMS)
- Benefits of system
- Specifications and functionality
- Keys to Success

## Balancing Directives through

- Guest
- Satisfaction

- Owner’s
- Interests

- Resource Management

**Notes:**
Hyatt’s Resource Management
Management Processes vs Driving Forces often opposing forces
Effectiveness of Management Process determines magnitude of resource cost 

## Energy Management Process

- Energy
- Purchasing

- Demand Side
- Management

- Operations Management

- Guest Satisfaction
- Owner’s Interest
- Legislation

## Demand Side & Operations Management

- Energy Accounting and Analysis
- Energy Efficiency Projects
- Operations Management

**Notes:**
This slide leads into the fact that energy accounting is a key component of DSM.   We’re funneling down to the detail . . .

## Existing Energy Accounting and Analysis Program

- _Energy Consumption_
- Electricity
- Natural Gas, Propane, Oil
- Water
- Purchased Steam, Hot Water and Chilled Water

- _Hotel Variables_
- Guest Nights
- Meals Served
- Heating and Cooling Degree Days

*Monthly tracking per property*

**Notes:**
Start by mentioning why Hyatt thinks tracking is so important.

## Benefits of Existing Program

- Predict energy and water consumption based on hotel’s variables
- Forecast for budgeting purposes
- Review operating procedures on a monthly and yearly basis

**Notes:**
“Hyatt wanted to explore options for more detailed tracking so we began by examining what we liked and didn’t like about the current system.”??

## Downsides to Existing Program

- Data quality varies between hotels and from month to month
- After-the-fact results don’t allow for proactive management and increase revenue losses
- Analysis methodology can cause improper conclusions
- Data collection is time consuming for the hotels

## UMS Specifications

- Real-time and historical trending of all energy and water data
- Automated reporting system for any data for any time period for any rate schedule
- Separate system from EMS
- Easy-to-use Windows interface
- Database management, upgrades, and 24-hour tech. support included in price
- Ability to interface with current data collection systems
- Turn-key solution, one point of contact

## Utility Monitoring System Benefits

- Load Information (Historical and Real-time)
- Automated Reporting
- System Recommissioning
- Identification of O&M Issues
- Energy Cost Allocation
- Power Quality Analysis
- M&V for Energy Conservation Measures
- Load Aggregation

**Notes:**
Depending on how long you will spend on this section - the next several slides -  you might consider talking from this slide only or shortening the words on the following slides.  On the other hand, if this is where you will spend the bulk of your time, you might leave all of the slides the way they are.

## Load Information

*  **Historical*:
-    Accurate long-term view of hourly energy
-    consumption
-    Compare utility bills to UMS report
-    View system variables at same time
*  **Real Time*:
-    Load shedding as required by utility contract
-    or based on hotel’s parameters

## Automated Reporting

- Automatic and precise reporting of energy and water information
- Daily, weekly, monthly, yearly reports of energy and water information at the touch of a button
- Comparison of different utility rates with built-in rate wizard

## System Recommissioning

- “Building Commissioning is the systematic process of ensuring and documenting that all building systems perform according to specification and design intent, consistent with the owner’s operational needs.”
- Building Commissioning Resource Page.“BuildingCommissioning.” 1998: 5 pages, March, 1999. Online.
- Available:http://www.mindspring.net/~usc_techsupport/newbdg/envsnd/envresll.htm

- More than T&B it involves complete performance testing to make sure system specifications are met
- Use the UMS to help recommission the system and to keep the system operating at its highest efficiency

## Identification of O&M Issues

- Is each system operating at its peak efficiency based on the system design and specification?

## Energy Cost Allocation

- Allocation of costs to specific loads or specific departments
- Make the laundry manager aware of the energy expenditures and watch the efficiency improve

## Power Quality Analysis

- Simple add-on module allows power quality    analysis on such variables as:
*Phase Voltage*
*Phase Amps*
*Power Factor*
*Harmonics*
- Voltage sags, dips and spikes caused by utility

## M&V for Energy Conservation Measures

- Show savings due to specific energy conservation retrofits
- No need for separate M&V system for performance contracts or utility rebate programs
- Built-in IPMVP and ASHRAE formulas for savings verification

## Load Aggregation

- E

- E

- Site 1

- Site 2

- Site 3

- E

- Marketer or Broker

- One Electric
- Load

**Notes:**
Natural Gas:  Larger the volumes purchased, generally the better pricing

Electric:  Larger the volumes purchased, generally the better pricing

Electric Load Factors

## UMS Selection Process

- Internet search for systems identified 30-35 potential systems
