- Slide 1
- Slide 2
- Rick Kmiecik Licensed professional mechanical engineer Licensed professional architectural /building systems engineer Director of Strategic Energy Initiatives at The University of Nebraska Medical Center President of Optimized Systems Engineering
- Slide 3
- What is missing in our industry today An organization that has the ability to combine good quality designs with energy efficiency, controls knowledge and a strong focus on equipment and systems that are maintainable and simple An organization that understands both sides of the building systems perspective. The designers perspective and the owner / operators perspective I am a believer that building efficiency can be achieved using good quality equipment and simple control strategies.
- Slide 4
- Optimized Systems Engineering New and existing building commissioning and retro commissioning Complete optimization of building systems and operations
- Slide 5
- Energy Consumption in the healthcare industry Healthcare sector ranks close to the top for total energy consumption among commercial buildings. According to Energy Star healthcare facilities spend an estimated $8.8 billion a year on energy consumption.
- Slide 6
- Possibilities Assume we as an industry reduce energy consumption by just 10% we will save approximately $880 million a year in energy consumption. Every $1 a non-profit healthcare organization saves on energy is equivalent to generating $20 in new revenues for hospitals and $10 for medical offices. Think of the billions of dollars of equivalent revenue generating you as an industry can do by saving just 10% in energy consumption
- Slide 7
- Slide 8
- Top Energy
- Slide 9
- Not knowing your facilities energy consumption All facilities should be metered in some fashion You cannot fix what you cannot see Plenty of easy, quick and simple rating systems to serve as a barometer to see where a facilities energy strengths and weaknesses are.
- Slide 10
- Not understanding and taking advantage of your utility rate structure Never use averaged electric rates when calculating savings Understand your peak demand and what it means Peak demand can account for 15%-50% of your total electric bill Manage your peak demand just as much as you manage your consumption
- Slide 11
- Not taking advantage of your local utility providers rebate and incentive programs OPPD Innovative Energy Efficiency Project (IEEP) Incentive Program. NPPD Energy Wise Programs.
- Slide 12
- UNMC Annual Electric Usage (kwhs) UNMC 20% Reduction
- Slide 13
- Energy Efficiencies
- Slide 14
- Not Educating your staff Most energy mistakes are not done intentionally but instead are done due to the lack of education Most individuals when given a choice want to do the correct and efficient thing and it is up us to make sure they know what the correct thing is When implementing energy improvement projects staff buy-in is essential to the success of the project.
- Slide 15
- Not willing to spend money in order to save money In every facility there is some low hanging fruit some quick wins, do NOT focus solely on these. Use quick win money as an opportunity to tackle the real challenges of reducing energy dependency. Combine quick win projects with longer return projects.
- Slide 16
- Mistaking Technology as the Solution Use technology to compliment your system The more complex a building becomes the more of a chance the owner is taking that the facility over time will become less efficient and less effective. Avoid black box technologies. If you dont understand it and cannot maintain it, do you really want to depend on it?
- Slide 17
- Lack of preventive maintenance An ounce of prevention is worth a pound of cure. Are your coils clean? Are strainers being cleaned? Are belts tight? Is everything aligned and balanced? Are your steam traps regularly tested and maintained?
- Slide 18
- Lack of Dynamic Resets on Controls The old days of picking a set point based on worst case system settings determined at the time of balancing need to end. With todays technologies we have the ability to see information and how systems are actually operating and performing and adjust accordingly.
- Slide 19
- Low Delta T Syndrome Do you know what your chilled water delta T is for your facility? Is it consistent year round? Buildings need to operate at the maximum delta T that the equipment will allow. Maximum delta T will increase chiller efficiency, reduce fan and pump horsepower consumed and increase equipment life.
- Slide 20
- Lack of Proper System Controls You cannot be efficient or effective if you cannot properly control your system. Need to be able to see the entire system to see how it reacts to different conditions. Need to see and react to Occupied and Unoccupied settings
- Slide 21
- Slide 22
- #10 Lack of proper System Controls #9 Low Delta T Syndrome #8 Lack of Dynamic Resets on System Controls #7 Lack of Proper Preventive Maintenance #6 Mistaking Technology as the Solution #5 Not Willing to Spend Money in order to save Money
- Slide 23
- #4 Not Educating your Staff #3 Not Taking Advantage of Utility Rebate and Incentive Programs #2 Not Understanding and Taking Advantage of Your Rate Structure #1 Not Knowing Where Your Facility is From an Energy Perspective
- Slide 24
- OSE Recommended Energy Savings Process Perform an Energy Study / Audit of the Facility Review the Study with the Facilities Staff Develop a Facility Energy Master Plan Go Through the Entire Facilities Equipment Develop System Deficiencies List Clean-up System programming and deficiencies Optimize Existing Equipment and Controls Finalize Standards, Graphics Project Closeout EDUCATE the Staff
