Common Energy Mistakes

• 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”
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.
Optimized Systems Engineering• New and existing building commissioning and
retro commissioning• Complete optimization of building systems
and operations
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.
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
Challenge
25% over the next 5 years.
Reduce your facilities energy consumption by
Top Energy
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.
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
Not taking advantage of your local utility provider’s rebate and incentive programs
• OPPD – Innovative Energy Efficiency Project (IEEP) Incentive Program.
• NPPD – Energy Wise Programs.

Energy Efficiencies
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.
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.
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 don’t understand it and cannot maintain it, do you really want to depend on it?
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?
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 today’s technologies we have the ability to see information and how systems are actually operating and performing and adjust accordingly.
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.
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

an Energy Perspective
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
