When EnergyWitness™ is first
installed in a campus or facility, the first order of business is
always a
diagnostic program. There are hundreds of issues detected that
require corrective measures. Once an action plan is in place and you
are making corrections,
you can start to focus on keeping your facility running at peak efficiency—an ongoing monitoring process. Equipment failures or
modifications, changing loads due to weather or space use, or
variances in purchased utilities can all effect your energy systems
operation. Continual monitoring is the only way to keep systems
running smoothly and to catch new issues. Data is the only way to
effectively monitor.

operational information requested.

It's All About the Data (the 98% You're Not Looking At)
Your BAS, other energy system components, and energy suppliers are
providing you with a huge amount of data. Data that can tell you how
your campus/facility is operating. Unfortunately, you're throwing 98% of it
away. Let's look at the numbers. A large facility may have 20,000
control and monitoring points, each one generating data. If you
sample each point at 15 minute intervals, you've gathered 1,920,000
meaningful pieces of data a day. That's over 700 million data
intervals a year.
How much do sites typically keep and see? You might have anywhere
from a dozen trend logs up to a couple hundred, capturing a tiny
fraction of the available information. Regular monitoring of 2% of the data available is a
generous estimate. Data—a complete, holistic, and historical
view—is the basis for effective monitoring of operations, energy
efficiency, and energy costs. It's no wonder EnergyWitness enables
our customers to find all the issues that it does. It
captures and
uses the data that's previously been thrown away.
Monitor 50X More Information in Less Time
So how do you monitor 2 million data intervals a day, or see how
your facility is functioning over the course of a week (13.4 million
data points) or a month (57.6 million points)? If it were easy,
you'd already be doing it. EnergyWitness does the hard work of data
collection and management, and provides you with a graphical view of
the data. Want to see how each building is running, or how your
chiller plant is functioning campus-wide? EWViewer lets you select the information you want and see a series of trend line
graphs. For regular monitoring, you need to run through the data
quickly to see how your energy systems are operating. All of the
data, not just two percent.
Delta T report: In addition to Delta T of the building primary
supply & return temperatures and building primary & secondary chilled water systems,
trends were added to chart to provide more information about
building and cooling operation.

With EWViewer you can monitor thousands of intervals in just a
few seconds. The graphical display shows several related trend lines
at once—typically five to ten. The display is nearly instantaneous
due to how EnergyWitness organizes and stores the data. If
everything is normal, an energy engineer can evaluate a graph and
move on to the next in about three seconds. It's actually faster to
monitor 100% of your data with EnergyWitness than it is to deal with
the two percent you normally see today.
Stop Treating Symptoms and Fix the Problem
The benefits of proactively monitoring all your systems are
enormous. It allows you to be able to finally get out of fire
fighting mode. Alarms from your BAS are a reactive
measure. Isolated to the particular event that triggered them, they
have no context, no trend line data or related system measurements,
they are a symptom of who-knows-what. The result is that the energy engineers see
significant numbers of alarms, sometimes hundreds per day, and just
ignore them due to lack of useful information. Monitoring through
EnergyWitness gives you a visual display of the data and your
operations. You see any issues that develop in context with trend
history information as well as the trends of related components.
When you discover an issue you can capture it through
EWIssueTracker and return for further
diagnosis later, when you can get to the real cause of the
problem and fix it properly.
