Everyone likes to say they
can save you money if you spend some on their product. How many can
verify the savings? Who can show you, hour by hour,
how many kilowatt-hours of electricity or cubic feet of natural gas
you're saving—and the dollar savings that represents? Who can
supply you with rock-solid data to justify the next engineering
redesign project? We can. EnergyWitness™ provides actionable information to:
- drive operational cost savings with verifiable results
- justify budget requests with indisputable operational data
- use staff more effectively, solving real problems instead of
treating symptoms
- allocate energy usage accurately across departments or cost
centers
- purchase energy at better rates
- extend equipment life by improving operations
- create a positive cash flow
(1) Setting a 3° approach allowed fans and resulting electrical
use to reduce overnight. (2) Setting fans to run in unison at lower
rpm further dropped energy consumption. Total estimated savings of
$40,000 per year. |
Verifiable Operational Savings
Conceptually it's pretty simple. The interval data that EnergyWitness
collects and uses to give facilities personnel the ability to
improve operations also records the impact of any and all changes.
When a correction is made, EnergyWitness will show the reduction in
energy consumption and costs immediately. Calculated trend lines
give you the ability to monitor bottom-line performance at a system
level, not just the individual components. So, you can track the
total hourly cost of operating your central plant—recalculated
every 15 minutes. The trend lines in
EWViewer provide verification of cost savings in living
color.
Justify Budgets with a Bazooka
No, we're not suggesting you use projectile explosives to make
your point. But we do suggest meeting with senior management armed
with a bazooka full of indisputable facts rather than the BB gun of
limited data and guesses that most facilities managers are used to.
EnergyWitness gives you the proof you need to justify budget
requests. And, it is easy to present information to management by
simply copying charts and data into Word, PowerPoint, Excel or other
program.
Effective Staff Deployment
Most facilities staffs are operating on guesswork due of the lack
of data. Technicians spend time chasing down reported symptoms
because they don't have the information to do anything else. Energy and control engineers
often take weeks to correct some
operational defect using trend logs (assuming they are solving the real problem, and not just treating a symptom
too). With the facts
provided through interval data, facilities staff can engineer fixes
for the real problems, and resolve them in far less time. Less time is
wasted firefighting and more effort can be devoted to improving
campus/facility physical assets in line with the master plan.
Accurate Energy Usage Accounting
There is an indirect cost recovery opportunity available for
universities, hospitals, and others doing funded research. Most
energy allocation is estimated based on square footage, not
accounting for a research lab's higher demand. EnergyWitness enables
tracking of energy consumption for individual spaces, which can be
built into research grants to capture additional funds.

The data showed equipment instability. In this case, fixing the
chiller's set point at 42°F eliminated the thrashing.

Efficient Energy Purchase Rates
Purchasing energy from utility companies for large facilities is
an exercise in predicting demand. Greater understanding of your
energy demands at typical and peak levels can reduce costs. With the
facts in hand, you can lock in the most favorable rates that cover
your needs and avoid high ratcheted surcharges for exceeding
contracted demand during peaks.
Longer Equipment Life
The biggest stress on any mechanical equipment comes from
starting and stopping, or running at maximum levels for long periods
of time. The diagnostic and monitoring capabilities in EnergyWitness
will quickly reveal situations where equipment is being stressed too
hard, either by excessive cycling or load. Smoother equipment
function means longer life and lower capital improvement expenses.
Example: Lighting retrofit takes 2.5 years to recoup the initial
investment while EnergyWitness becomes cash flow positive in just a
few months.

Positive Cash Flow
A typical energy conservation project involves replacing dated
components with new, efficient equipment. This can range from a
lighting retrofit to replacing all the chillers. Such projects
require a huge up-front investment to fund a few months of design
and planning, followed by 6 – 18 months of construction. It can
be multiple years of negative cash flow before the project is
complete and stipulated savings begin, and much longer before the
return on investment is fully realized.
With EnergyWitness, savings (verifiable, remember) start in just
a few weeks. The initial investment is recovered in 4 – 5
months, and thereafter generating a positive cash flow. The realized
savings and additional cash could even fund other projects once the
operational issues are resolved.
Seeing is Believing
