Domestic Energy

  • Many smart energy metering trials
  • Ireland’s CER ran an 8,000-home customer

behaviour trial, technology trials, cost-benefit analysis

  • Motivations are the usual combination of

– Better Customer Information and Choice – Lower Energy Bills – time of use tariffs – Greater Energy Efficiency and Reduced Costs – Reduced CO2 emissions

Domestic Energy

  • CER has decided to proceed and include

– In-home Display device – Smart Bills – Time-of-Use Pricing – Pre-payment services

Smart meters = sensors

  • From the HAN, we regard smart meters as

generating sensor data, which is what CLARITY is interested in;

  • Working with Episensor, we deployed our
  • wn in-home smart metering to 2 dozen

homes, over years

  • Monitor the electrical consumption within the

home, on a per-minute basis

Smart meters = sensors

  • Components …

– Cuff, mains power, Zigbee, local DB on PC, broadband to cloud, web apps – Now plugPC and Raspberry Pi

So what ?

  • Personal feedback reduces demand ?

– Olympic Peninsula Project – Darby Review Paper – ENEL 27 million smart meters – Microsoft Holm & Google power meter – Irish Commission for Energy Regulation behavioural trials – … and many others

  • We are interested in different kinds of

intervention based on fine-grained usage sensing, not IHD, but more

Intervention 1

  • Weekly email … Google Powermeter did this also … but

with comparisons against others

Intervention 2

  • Touchscreen display

Intervention 3

  • Web portal
slide-18
SLIDE 18

UNIVERSITY COLLEGE DUBLIN  DUBLIN CITY UNIVERSITY  TYNDALL NATIONAL INSTITUTE

Intervention 4

  • Colour-changing soft furnishings
  • Tablecloth, cushions, etc. - where

colour changes ambiently reflect the +/- energy usage vs. typical historical norm for that day/time

Interventions ?

  • Guess what ? We found the same as

everyone else … initial enthusiasm gives way to bad habits - need to continuously inform

  • Real role for persuasive technologies …

captology

Strange outcome

  • A strange outcome was the interest in

the heatmaps as a tool to summarise lifestyles;

  • One ambient, cheap sensor tells a lot

about living patterns;

  • Subsequently working with

ethnographers and geriatricians on monitoring the lifestyles of people;

  • All from a cheap €100 option

UNIVERSITY COLLEGE DUBLIN  DUBLIN CITY UNIVERSITY  TYNDALL NATIONAL INSTITUTE

Strange Outcome

  • This will be even cheaper with rollout of

smart meters, where this can be done for free … direct interface to the meter

  • Could allow easy inter-user

comparisons, comparison across peers, long-term deviation detection

  • And that was very interesting, but …

Sensing The Home

  • This is total energy usage in a home,

covering all appliances.

  • But, we have gone a step further …

Sensing the Home

  • Analysis of the electrical power usage of a

home provides appliance signatures.

  • This enables identification of different types
  • f household appliance usage.
  • We gathered groundtruth and used machine

learning (SVM) to build classifiers for devices

  • Assessed accuracy at 95% precision/recall
  • Use this in smart bills, and behaviour

analysis

E.g. Electric Kettle

  • 1 year
  • June
  • nly
  • This tells what is happening in my home
  • Better when combined with other appliances

and sensors, a cheap ambient sensor

E.g. Electric Shower

Appliance Detection

  • Other ways to capture appliance usage …

contact sensors, circuit-based or appliance- specific sensing

– We show its not actually necessary

  • We don’t focus on dynamic machine

learning, we post-process

– who would need to know ?

Conclusion

  • Monitoring home energy usage has great

potential

– IHD and billing as the sole user intervention doesn’t maximise potential impact – Autonomous appliance management is better – Can be much more than just energy saving

  • Can enable other uses when smart metering

architecture permits user access to own data

  • It shows the richness of good data and is an

ICT challenge !
