monitoring energy in real-time
DESCRIPTION
The importance of per second sampling when monitoring energy, no other resolution will let you understand exactly what power your using at any given time.TRANSCRIPT
Green Running Presentation IHG 1
The benefits of second by second energy monitoring and Instantaneous
live usage feedback for
energy saving and behavioral change.
Green Running Presentation rev1 JM.pptx IHG 2
All energy readings are a combination of multiple devices all on and
Drawing power at the same time.
Microwave
KettleToaster
How it works – why beneficial?
Green Running Presentation rev1 JM.pptx IHG 3
All energy readings are a combination of multiple devices all on and
drawing power at the same time
Every appliance has an effect on the total load
Water Heater
Ice Machine
How it work..cont
Green Running Presentation rev1 JM.pptx IHG 4
Good for bench marking and seeing trend data
Full Day half hourly
White = Phase One
Green = Phase Two
Red = Phase Three
Green Running Presentation rev1 JM.pptx IHG 5
Immediately see the large devices are using power
Full Day Second by Second
Could also miss vital information like power cuts to your building
Green Running Presentation rev1 JM.pptx IHG 6
Can see exactly what is turning on and off
Zooming In Second by second
Detail of power cut risk
Green Running Presentation rev1 JM.pptx IHG 7
Can see exactly what is turning on and off?
Zooming In Half hourly
Green Running Presentation rev1 JM.pptx IHG 8
Not a huge amount better than half hourly
Zooming In Minute
Hence bad press
Green Running Presentation rev1 JM.pptx IHG 9
Green Running – what do I mean by
Second by second
Graph for half hourly data blurred data
Graph with Greater than second by second – blurred data but prettier
Graph for second by second data can actually see what is happening!
Perfect for ISO14:001 improvement
Quick Example
Green Running Presentation rev1 JM.pptx IHG 10
Office hours are 8 – 4pm, office, no major machinery, lots of computers
During
Green Running Presentation rev1 JM.pptx IHG 11
One VERY large device equivalent of ten kettles being turned off at the same time
After
Green Running Presentation rev1 JM.pptx IHG 12
More like a normal day with some more obvious appliance uses
Saved thousands of pounds per year and the energy company more so

Behavioural change
First time people can actually see the differences in cost for each item
A cause and effect when someone turns on an appliance
LIVE – “REAL TIME” second by second stream to the Display
Green Running Presentation rev1 JM.pptx IHG 15
Example Video

• Compare consumption & cost across floors, buildings, & sites
Displays – Real time tools
17
• Compare consumption & cost with previous data & “Perfect Days”
Displays – Trending and BenchMarks
Green Running Presentation rev1 JM.pptx IHG 18
Behavioural change – Staff can see how their cause and effect is being
monitored. Allows people to gain a greater understanding of what is actually using
the power
Leaving on the air conditioning overnight is equivalent to 500 LED bulbs or
100 60W bulbs
Educational tool - Shows the difference between the niceties and actually
energy saving factors
Displays – Second by second
Combining existing behavioral change feedback with second by second displays
Gives even greater understanding and awareness to employees - eViewer

Alarms and Warnings
Be told your about to have a power cut prior to having one
Be informed if there was any out of hour irregular usage – Security
• Quote from Gardline 140001 report
• Quote from Crown Plaza group head
Green Running Presentation rev1 JM.pptx IHG 20
14001 : Perfect
MOT – Just want to just understand where you are, don’t go and spend money on being capital energy saving equipment unless you actually know where you are at and what you need.
Green Running Presentation rev1 JM.pptx IHG 21
Real Time displays – 0.1 second is perfect and smooth, one second is
ideal and gives you everything you need, anything more is better than
nothing but you lose information
Faster Sampling than every second?
Sampling at 50 KHz (50,000 times per second) gives harmonic information,
power, frequency, each appliance usage and effect on power factor factor.

To send 86400 data-points up to our dedicated server = 3MB per day
Less than 30secs of Facebook browsing!
Does it cost more?
The equipment cost is the same, it is a custom built hardware with the
same chips as meters, just with more sophisticated software platform
allowing the speed and analysis
The storage is on the Microsoft azure dedicated data platform so is a
cheap storage version and less than £25 per month.
