Benefits of Existing Benefits of Existing ProgramProgram

• 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 Downsides to Existing ProgramProgram

• 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 SpecificationsUMS 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 Utility Monitoring System BenefitsBenefits

• 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 InformationLoad 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 ReportingAutomated 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 RecommissioningSystem 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.

• 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 IssuesIdentification of O&M Issues

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

Energy Cost AllocationEnergy 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 AnalysisPower Quality Analysis

Simple add-on module allows power quality analysis on such variables as:

Phase VoltagePhase AmpsPower Factor

Harmonics

Voltage sags, dips and spikes caused by utility

M&V for Energy M&V for Energy Conservation MeasuresConservation 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
