monitoring energy in real-time

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?


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


Good for bench marking and seeing trend data

Full Day half hourly

White = Phase One

Green = Phase Two

Red = Phase Three


Immediately see the large devices are using power

Full Day Second by Second

Could also miss vital information like power cuts to your building


Can see exactly what is turning on and off

Zooming In Second by second

Detail of power cut risk


Can see exactly what is turning on and off?

Zooming In Half hourly


Not a huge amount better than half hourly

Zooming In Minute

Hence bad press


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

During


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

After


More like a normal day with some more obvious appliance uses

Saved thousands of pounds per year and the energy company more so


End of Techy Part


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


Example Video

Green Running 121112.ppt UKPN 16

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

Displays – Real time tools

17

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

Displays – Trending and BenchMarks


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


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.


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.
