Portfolio Manager• Free, online tool• The industry standard in commercial real estate• Track changes in energy, water, GHG emissions over time
within a single building or entire portfolio• Understood and used by many owners managementUnderstood and used by many owners, management
companies, local governments, potential buyers and lenders

Portfolio Manager
Energy Utilization Index (EUI)/Energy Intensity - measure of the total energy consumption over the course of a year kBTU/SF
Baseline Energy Use
total energy consumption over the course of a year, kBTU/SF
Pros:• Industry standard approachIndustry standard approach• Simple to calculate• Easy to compare buildings year-to-year
Cons:• Not weather-normalized• Does not account for building use factors.
Portfolio Manager
ENERGY STAR rating – a benchmarking tool
Pros:• Weather-normalized• Accounts for building use factors
T k f ili f• Track facility performance• Assist with achieving EPA Recognition & LEED certificationsLEED certifications
Cons:• 1-100 rating not available for all building types1 100 rating not available for all building types

Energy Audit Case Study
Started with a rating of 63…• Set up schedules within the building control system to shut the air
handling units off when zones were unoccupied
• Used economizer mode on air handling units during cooler weather to avoid running chiller plantto avoid running chiller plant
• Minimized/eliminated use of steam humidifiers within 19 air handling units and rebuilt/replaced steam traps.
• Programmed ‘Optimized Start’ for air handlers with Energy Management Control System (EMCS)
• Purchased ENERGY STAR equipment
• Installed variable frequency drives for cooling tower fans
I ll d i i• Installed motion sensors in restrooms

Energy Consumption in a Manufacturing Environment
Benchmarking Difficulties:
• 2 to 1 Computer to Employee Ratio• Lack of Useful or Relevant Data• Wide variety of industrial & Engineering Applications• Extensive Component Testing• Intensive Engineering, Laboratory & ResearchCli• Climate
Energy Consumption in a Manufacturing Environment
Alternative Databases:
• Commercial Building Energy Consumption Survey (CBECS) #334Man fact ring Energ Cons mption S r e (MECS)• Manufacturing Energy Consumption Survey (MECS) Climate Data
• North American Industry Classification System (NAICS) building Type
• IFMA 2007/2008 O/M Survey Data for Manufacturers
Approach to EAP2 EUI Values across the Climate Zones:
• Option A or B were not options• Option C3 Approach Selected• Energy Use Intensity Ratings• Leveraged Climate Zone• Leveraged Energy Intensive BusinessLeveraged Energy Intensive Business• Confirmed Our Energy Use was 19% Lower Than National Average Climate Zone 5 starts with 2,000 CDD, whereas the
Phoenix Metropolitan Area 30-year average is 4 125Phoenix Metropolitan Area 30-year average is 4,125 CDD with 1,125 HDD, which places one of the highest energy burdens in Climate Zone 5 on the GDC4S Scottsdale Facility.
Energy Consumption in a Manufacturing Environment
Achieving LEED EB
• Selecting the Appropriate Option• Spot Metering – Alternate Approach• Use of Largest Data Set Option “C” Calculator(8 common bldg’s)
• Having Access to Historical Data• Having Access to Historical Data• Quantified energy use by BTU/Employee • Aligned Climate, Temperature and Relevant g pBuilding Data

Benchmarking difficulties for a convention center
• Fear of KNOWING the unknown • “What you don’t know can’t hurt you!”y y
• Many cities have not required sustainability in public assembly venues
• Self Regulate or wait to be regulated….
• Limited dataV i d f t d d tt d• Varying degrees of use-event days and attendance
• Bad economic years look great on a sustainability curve!
• 3rd Party impacts- clients decorators needs and use of the3rd Party impacts clients, decorators needs and use of the facility
• Same employees different results :/
• Alternative databases for public assembly environments
What’s Happening NOW??E S P f li M• Energy Star Portfolio Manager groups
IFMABOMAAUSTIN- Now required for all commercial facilities over 5000sq.ft.
• Energy Star for the Entertainment Sector Partner groupAustin Convention CenterCharlotte Convention CenterMonona Terrace Community and Convention CenterNorthshore Harbor CenterOregon Convention CenterPalmer Event Centere ve Ce eSaint Paul RiverCentreSan Diego Convention Center Virginia Beach Convention CenterVirginia Beach Convention Center
What is on the HORIZON….
• IAAM and IFMA Sustainability work groups creating databases and standards/best practices
• IFMA Foundation producing excellent “How to’s” in all areas of sustainability
• More and more regulations nationwide
Approach to LEED – EB certification
Measure against yourself (current 12 mo period against a 3 year average)g y g )
Pros
• Very simpley p
• Easy to control
ConsCons
• Limited point opportunity
• How long have you been implementing energy saving• How long have you been implementing energy saving initiative???
Approach to LEED – EB certification
Measure against other leaders within the Energy Star groupsStar groups
Prosilli i i• Willing participants
• Easily obtainable dataCons• Cream of the cropp• Not a representative cross-section
Approach to LEED – EB certificationCompile data from facilities outside of Portfolio Manager
PPros• Better cross-section
B tt t it f i l k t t• Better opportunity for regional or market segment comparisons
Cons• More resistance• How will this impact me???p• Open records act

What does this mean to Facility Managers?
The IFMA Energy Challenge: ENERGY STAR
What does this mean to Facility Managers?
• Utility costs for the average IFMA facility is $2.56 per square foot • $200 Billion per year on electricity, gas and water in commercial $ 00 illio pe yea o e ec c y, g s d w e co e c
facilities• A 10 percent improvement in building energy efficiency would save
about $20 billion in operating cost, reduce greenhouse gases, and id i i i ib i b liprovide a significant contribution to your company’s bottom line.
Reduce baseline facility energy use by 15% f y gy yor more, and provide a process for continuous improvement in energy
