An energy model provides valuable insight into a building's energy usage and costs. It involves an on-site investigation to collect detailed data on the building's operations, equipment, schedules and weather. This data is used in high-end software to create an accurate digital model of the building that can identify savings opportunities from improving efficiency. Implementing the recommended proposals from an energy model leads to verified energy and cost savings. Ongoing monitoring is needed to ensure performance is maintained over time, as a building is an ecosystem that needs holistic analysis to manage its energy use effectively.
The Business Case for Energy Models-15-0122
- 1. THE (AMAZING) BUSINESS CASE FOR ENERGY MODELS 22 January 2015
- 2. Mitchell Gleason Operations Leader Matt Abid Business Development Leader Jim Dirkes President/CEO
- 4. 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
- 5. DID YOU KNOW
- 6. 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?
- 7. ENERGY MODEL OF A GOLF SWING
- 8. GOLF SWING HAS MANY PARTS Grip Alignment Club speed Arm placement Hip rotation Head down Hand placement Follow through AND..?
- 9. THAT IS A LOT OF INFORMATION TO REMEMBER SOME 80+ TIMES IN A ROUND.
- 10. YOUR BUILDING IS MORE COMPLEX. Heating and cooling schedules Occupancy, lighting and equipment schedules What happens inside the building Weather
- 11. WHERE IS THE ENERGY GOING? Do you have time to check? Do you know where to look?
- 12. YOU NEED A PRO!
- 13. WHAT IS THE BEST WAY TO DECIDE ON CAPEX INVESTMENTS
- 14. Custom-prepared, tailored, calibrated savings for your exact building Average savings for an (undefined) average building ?
- 15. ON-SITE INVESTIGATION Interviews with key personnel Measurement of key equipment Building layout and uses
- 16. Schedules for: Occupancy Lighting Equipment Review utility bills Use actual weather data for billing period DETAILED DATA
- 17. HIGH END SOFTWARE Draw building geometry Define major energy users Identify heating and cooling systems
- 18. VALIDATION Do calculations match reality? If not, what was missed or misunderstood?
- 19. After the due diligence & calculations match reality What can we make better? What difference will it make? Calculate savings from fixing obvious problems Calculate savings from improving operations & technology Accurate savings & accurate cost estimates drive actionable, data-driven recommendations SAVINGS & RECOMMENDATIONS
- 20. CLIENT #1: Church boiler oversized 3x CLIENT #2: School boiler oversized by 4x (planned addition never was built) BOILER SIZE
- 21. 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
- 22. COLD WINTER LARGE YMCA: Minimal increase (heating cost up 1-2%) MEDIUM CHURCH & SCHOOL: Moderate increase (heating cost up 12%)
- 23. 100,000 SF WAREHOUSE: Client was very interested in converting lights to LED Motion sensors on existing lights 5 year payback LED payback Never LED LIGHTING
- 25. Implement the best (contractor-vetted) proposals Verify savings On-going energy consultation
- 27. WHAT YOU DONT MONITOR YOU CANT MANAGE
- 28. If your golf clubs sit in storage all winter, will your swing be the same in the spring? If you dont monitor your facility, will it continue to be as efficient as it was after the recommendations from the energy model were enacted?
- 29. NO!
- 30. YOUR FACILITY IS AN ECOSYSTEM
- 31. 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 CLOSING THOUGHTS
- 32. NEXT STEPS
- 33. Dont delay any longer. Have a pro conduct an initial walk-thru to determine your savings potential Contact us to get more detail Ask questions!
