Portfolio Manager – Helping You

Track Your Performance

¾ Free online tool where you can:

• Benchmark the energy use of all of your buildings –

all will receive an energy use intensity (EUI) and

some will receive ratings on a 1 100 scale

some will receive ratings on a 1-100 scale

• Track changes in energy use over time in single

buildings, groups of buildings, or entire portfolios

Energy and the Lodging Industry

• 5th largest commercial energy

consumer

• Spend $7.5 billion per year on energy

• Utility costs rose 4 5% in 2007

Lodging Environmental Impact

• Annual energy consumption

– 69 billion kWh of electricity

– 208 billion cubic feet of natural gas

• Equivalent to 53 million metric tons of CO2 per year

• A 10% reduction in lodging industry energy

consumption would be equivalent to

– Reducing CO2 emissions by 5.3 million metric tonsg y – Taking almost 1 million cars off the road for 1 year

– Offsetting the annual electricity consumption of more than 730,000 homes

Tracking Campaigns:

Master Accounts

• Objective: Allows colleges and universities to track

progress of campaigns, for example:

• University systems can track individual campuses

• Energy saving competitions among residence halls or other buildingsEnergy saving competitions among residence halls or other buildings

• Process:

I tit ti t M t A t

• Institution creates a Master Account

• Master Account appears in a public registry

• Individual users can share facilities with Master Account

M t A t h ld i f ll f iliti th t h b

• Master Account holder can view progress for all facilities that have been shared

(24)

View (and Reporting) Options

• The “My Portfolio” page uses views to display summarized data • A view is a set of columns that display various data in a table

• Portfolio Manager provides the ability for a user to create their own • Portfolio Manager provides the ability for a user to create their own

view by selecting the columns (up to seven at a time) to display on the My Portfolio page

• It also enables the user to select the number of facilities that can display on the My Portfolio page (e.g., 25, 50). There are over 30 different data columns that can be selected

• Any view can be set as the default view and these views can be downloaded into a Microsoft Excel spreadsheet for further analysis

Statement of Energy Performance

• Objective: The SEP can be generated for purposes other

than applying for the ENERGY STAR Label

• LEED-EB certification process R l t t t ti

• Real estate transactions

• Maintaining a Facility Summary Report

• Process:

Process:

• User selects time period of performance

• Tool generates 1 page summary with energy use, cost, and emissions figures

S l i l d d d h f ll SEP i t d • Summary also included as second page when full SEP is generated

(26)

Percent Energy Reduction

• Objective: Provide a metric to show a percent change in

energy use over time

• Creates tracking capability for all space types

• Process:

• For non-ratable spaces the tool compares weather normalized source energy use between two periods and adjusts for any changes in square footage

• For ENERGY STAR ratable space types, the tool compares energy use between two periods adjusting for changes in weather and business activity

(27)

Water Tracking

• Objective: Allow users to track water use in Portfolio

Manager

• Continued emphasis on tracking all utilities

• Lay groundwork for understanding the relationships between water and energy use

• Process:

• User can select “Add Water Meter” for any facility

• User can identify water meters as indoor, outdoor, or wastewater • Tool displays water use totals for any 12 month period
