monitoring energy in real-time

The benefits of
second by second
energy monitoring
and Instantaneous
live usage
feedback for
energy saving and
behavioral change.

How it works – why beneficial?

All energy readings are a combination of multiple devices all on and
Drawing power at the same time.

Kettle

Toaster

Microwave

How it work..cont
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

Full Day half hourly
Good for bench marking and seeing trend data
White = Phase One
Green = Phase Two
Red
= Phase Three


IHG

4

Full Day Second by Second
Immediately see the large devices are using power
Could also miss vital information like power cuts to your building


IHG

5

Zooming In Second by second
Can see exactly what is turning on and off
Detail of power cut risk


IHG

6

Zooming In Half hourly
Can see exactly what is turning on and off?


IHG

7

Zooming In Minute
Not a huge amount better than half hourly
Hence bad press


IHG

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
Office hours are 8 – 4pm, office, no major machinery, lots of computers


IHG

10

During

One VERY large device equivalent of ten kettles being turned off at the same time


IHG

11

After
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

LIVE – “REAL TIME” second by second stream to the Display

First time people can actually see the differences in cost for each item

A cause and effect when someone turns on an appliance

Displays – Real time tools

• Compare consumption & cost across floors,
buildings, & sites

16

Displays – Trending and BenchMarks

• Compare consumption & cost with previous
data & “Perfect Days”

17

Displays – Second by second
Combining existing behavioral change feedback with second by second displays
Gives even greater understanding and awareness to employees - eViewer

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

Educational tool - Shows the difference between the niceties and actually
energy saving factors

Leaving on the air conditioning overnight is equivalent to 500 LED bulbs or
100 60W bulbs


IHG

18

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

14001 : Perfect

• Quote from Gardline 140001 report
• Quote from Crown Plaza group head

Faster Sampling than every second?
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

Sampling at 50 KHz (50,000 times per second) gives harmonic information,
power, frequency, each appliance usage and effect on power factor factor.

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.

Does it cost more?
To send 86400 data-points up to our dedicated server = 3MB per day
Less than 30secs of Facebook browsing!

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.
