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
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

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
