• Energy: 30% reduction by 2015 (FY03 basis)

• Water: 15% reduction by 2015 (FY07 basis)

A l d t ti• Annual energy and water use reporting

• Energy use benchmarking

• Comprehensive audits in 25% of your facilities annually*y

Why Use Energy Star Portfolio Manager?

• Enables reliable “apples-to-apples” building performance comparisons (ratings)p ( g )– Normalizes for the dominant drivers of energy use (floor area,

operating hours, occupant density, weather, etc)– Ratings based on real performance of real buildings “most methodsRatings based on real performance of real buildings

• Requires minimal data (annual energy use data and simple building descriptive data)

What We Have To Do To Enable P tf li MPortfolio Manager

• Assemble energy use and descriptive data

• Populate data to Portfolio Manager

• Setup appropriate access levels to users

• Incorporate use into operationsIncorporate use into operations

BENEFITS: How MEDCOM Can Use for Strategic Energy ManagementStrategic Energy Management

• Use Measured energy and water use data to:– Support annual reporting– Establish energy and water use baselines– Minimize uncertain energy and cost accounting (allocations)Minimize uncertain energy and cost accounting (allocations)– Support budget planning– Enable performance ratings

• Use Performance Tracking– ID when buildings are improving, holding, or degrading

M t d l f– Measure progress toward goals or performance achievement

BENEFITS: How MEDCOM Can Use for Strategic Energy Management (cont )Strategic Energy Management (cont.)• Use Performance Ratings to:

Find the good bad and ugly in your portfolio– Find the good, bad, and ugly in your portfolio– Add a performance component to your targeting – Target low performers (send teams where most needed)– Avoid sending auditors to high performers– Scope your expectations up front– Set targets for improved performance (building installationSet targets for improved performance (building, installation,

region, etc.)– Gain recognition for high performers (Energy Star)
