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

Energy $ Water $ Waste $ Environmental $ Guest Satisfaction Owner’s Interests Balancing Directives through Resource Management

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

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

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

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

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, Online. Available: 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

UMS Selection Process Internet search for systems identified potential systems Further research identified 8 companies that met Hyatt’s requirements Request for Proposal (RFP) issued to 8 companies Reviewed RFP responses with 3 companies selected for second round of questions and site visits New Horizon Technologies of Butte, MT selected as partner Entire process spanned four months.
