WHY ARE WE HERE?
USGBC mandated Energy Models for LEED certification
Too often, just a hoop to jump through for LEED certification
Energy Models provide valuable insight independent of LEED
DID YOU KNOW …
Your Facility is your #1 most manageable cost?
Utility variations that are attributed to weather, usually have nothing to do with weather?
Would you spend $100,000 or more anywhere else on your bottom line and not investigate ways to save money?
ENERGY MODEL OF A GOLF SWING
GOLF SWING HAS MANY PARTSGripAlignmentClub speedArm placementHip rotation
Head downHand placementFollow throughAND…..?
THAT IS A LOT OF INFORMATION TO REMEMBER SOME 80+ TIMES IN A ROUND.
YOUR BUILDING IS MORE COMPLEX.
Heating and cooling schedulesOccupancy, lighting and equipment schedulesWhat happens inside the buildingWeather
WHERE IS THE ENERGY GOING?
Do you have time to check?Do you know where to look?
YOU NEED A PRO!
WHAT IS THE BEST WAY TO DECIDE ON CAPEX INVESTMENTS
Custom-prepared, tailored, calibrated savings for your exact building
Average savings for an (undefined) average building

ON-SITE INVESTIGATIONInterviews with key personnelMeasurement of key equipmentBuilding layout and uses
Schedules for:• Occupancy• Lighting• Equipment
Review utility bills
Use actual weather data for billing period

After the due diligence & calculations match realityWhat can we make better? What difference will it make?• Calculate savings from fixing obvious
problems• Calculate savings from improving
operations & technologyAccurate savings & accurate cost estimates drive actionable, data-driven recommendations
SAVINGS & RECOMMENDATIONS
CLIENT #1: Church boiler oversized 3x
CLIENT #2: School boiler oversized by 4x (planned addition never was built)
BOILER SIZE
Relatively new boiler (10 yrs.) should have been ~80% efficiency• Energy model validation
suggested ~50%• Further investigation
proved the model correct. The client began saving $5,000/yr.
BOILER EFFICIENCY
COLD WINTERLARGE YMCA: Minimal increase (heating cost up 1-2%)MEDIUM CHURCH & SCHOOL: Moderate increase (heating cost up 12%)
100,000 SF WAREHOUSE:Client was very interested in converting lights to LEDMotion sensors on existing lights – 5 year paybackLED payback – Never

HOW TO USE YOUR ENERGY MODEL
Implement the best (contractor-vetted) proposals
Verify savings
On-going energy consultation
WHAT’S THE TIPPING POINT?
WHAT YOU DON’T MONITOR YOU CAN’T MANAGE
If your golf clubs sit in storage all winter,
will your swing be the same in the spring?
If you don’t monitor your facility, will it continue to be as efficient as it
was after the recommendations
from the energy model were enacted?
NO!
YOUR FACILITY IS AN ECOSYSTEM
Buildings are ecosystems and need holistic analysis
Energy models are an investment
A real pro makes the investigative effort small and ROI large
Holistic energy models are the best tool for making energy-related decisions and making sure performance is maintained
