Introduction
Building operators and corporate real estate managers everywhere are
now charged with moving their facilities toward ‘best practice’ levels
of energy management and occupant engagement. The journey begins with
understanding—you need to measure before you manage, make the invisible
obvious, and generally walk before you run. Here are seven modes of
thinking and acting to avoid on your way to success:
Sin
of Wrong Accounting: Capital budget financing
For manufacturers and critical facility managers, energy shouldn’t be
just a bill at the end of the month. It’s not a fixed cost beyond your
control. By considering energy as a variable cost and including it
within Cost of Goods Sold (CGS), you make energy consumption more
visible. A first step in your plan for energy efficiency is to take a
baseline measurement. Then you have something to gauge your progress as
you identify, analyze, prioritize and implement Energy Conservation
Measures (ECMs). Start with the activities that will give you early,
tangible, and statement-making results that will build momentum. Make
it a practice to measure before and after an ECM in order to document
your successes. Secure sufficient resources to get the job done, going
with external consultants if the resources are not there internally.
Lesson:
Measure energy efficiencies before and after you get started on
your project. This provides a baseline and will help document your
achievements.
Sin of Fits-and-Starts:
Once-and-done commissioning
You cannot achieve long term improvement goals or energy reduction
mandates through periodic retro-commissioning or using a SWAT team to
fix problems after you get a phone call. Those approaches may provide
temporary benefits, but they are only slowing the performance decline.
Today’s critical facilities have the connected infrastructure to
support cloud-based data management and analytics software for
persistent, ongoing building commissioning. Rules-based monitoring and
analysis of real-time and near real-time information, streaming from
energy meters and building equipment, can reveal energy waste due to
improper setpoints or faults in equipment, saving money day after day.
Lesson: Be
persistent when measuring energy waste. Consistently
measuring real-time data already streaming from meters and building
equipment is an ongoing process.
Sin of Flying Blind: Making
decisions without tapping into your own data
Many energy benchmarking tools rely on high-level comparisons of
similar buildings. While these tools have their place [both the US
EPA’s Portfolio Manager and the Energy Performance Certification (EPC)
system in Europe are key to meeting state and municipal energy
disclosure regulations] they cannot tell you how to address issues in
your own facility. Real insight only comes when you have clean,
accurate data about your unique environment and use that for analysis
and decision making. To support the systematic practice of identifying
the root causes of your energy waste and prioritizing conservation
measures, you need to plan for the collection of actual time-series
data from your meters, submeters, sensors, and building
equipment—correlated and analyzed by your own team.
Lesson: Ensure
your data collection is clean and accurate before applying analytics
tools.
Sin of Caveat Emptor: Ripping and
replacing equipment without first analyzing your building’s data
Many building owners/operators deal with myriad equipment manufacturers
and data structures in the daily running of their facilities. Few have
a homogeneous environment which can provide a unified view across
assets, systems, and buildings. Moreover, it has been common practice
for large equipment vendors to protect their markets through the use of
proprietary protocols that make it hard for subsystems to exchange data
in the interest of top-down, whole-building energy optimization.
However, this is no reason to spend millions of dollars to standardize
equipment. Today there is intelligent software to create a common and
open data infrastructure. These tools can layer across disparate
equipment and provide a common view of data and events, regardless of
the underlying manufacturers.
Lesson: An
open data infrastructure, when layered across disparate
equipment, buildings and systems, provides a common, unified view of
whole-building energy optimization.
Sin of Narrow Scope: Limiting your
vision to only BAS-connected equipment
Equipment connected to the BAS typically represents less than 50% of
the energy consumed in a building. By limiting your attention to BAS
data, you are ignoring more than half of your energy costs! A better
strategy is to create a data architecture that
will let you connect to equipment and data sources beyond the building
control systems. This way, you will be able to expand when you bring
new systems into the picture, incrementally adding lighting, plug
loads, water, waste water, and on-premises generation like solar, etc.
Embrace system-wide flexibility. Carnegie Mellon University
lowered their energy footprint by 30% by integrating their systems.
Lesson: Your BAS
will only provide you with data representing about 50%
of the energy your building consumes. Remember to connect data sources
beyond the BAS to understand the big picture.
Sin of Stealth Mode: Attempting
energy management without involving all stakeholders
If you really want to reduce energy costs, it’s not enough to focus on
the efficiency of the equipment. You need to engage with all
stakeholders: IT, facility managers, engineers, and don’t forget the
occupants! Getting IT department buy-in and counsel from the earliest
stages of a new energy management project is the best way to ensure
your proposed solutions will meet corporate data security and service
contract requirements. To engage occupants, strive for cleanly
designed, easy-to-interpret visualizations to present the data.
Behavioral change starts with helping people to see the impact they
have on consumption. These visuals need to be (near) real-time to
enable positive reinforcement. If people don’t see data until the end
of the month, it reinforces the feeling of helplessness.
Lesson:
Identify key stakeholders who are impacted by an energy
efficient building or campus. Provide them with clear, up-to-the-moment
data so they understand their role in energy consumption and can have a
positive impact.
Sin of Short-Term Thinking:
Deploying solutions without future-proofing
It’s a marathon, not a sprint. There will always be something more to
do, another good idea, another way to improve. We know that the next
generation of enterprise computing will deliver more applications via
cloud services and mobile devices, and we know that staying current
with security technology best practices will continue to be an ongoing
battle. With such macro-trends in mind, focus on flexible technologies
that can integrate with systems and tools that you haven’t even
implemented yet. Avoid specific purpose technologies that might deliver
short-term but create hurdles when you evolve. Start with a vision—even
if it includes ideas and goals you might not think are possible for
you—it will act as a North Star to guide your decisions today and into
the future.

Lesson: Get started with your vision and strategy by including
short-term and long-term goals. Investigate flexible technologies that
can evolve and integrate with your tools.
Conclusion
The best starting point for achieving your energy management goals is
to create a vision—think several years down the road. Then find the
right technologies, flexible enough to enable today’s needs and
tomorrow’s goals. Use software as a common infrastructure to connect
disparate data sources—including future systems. Lastly, create
visibility throughout your enterprise to make the invisible obvious and
enable all stakeholders to have an impact. Avoiding these “7 Sins” may
seem challenging, but taking the
time to understand them and how they impact your enterprise will ensure
you are on the right path to meet your long-term goals.
