Past devices basis for planning?• Historic demand well mapped• Real-time meters – emerging
Future Added Demand Volatility?• EVs & Electrification of heat • What if IoT x 10 by 2020 (Cisco)• ARM 150bn+ chips by 2020• Robotics, 3D printing, batteries• Assisted living / medical

Software based – DC monitoringInference - Network Scan (MAC address tracking)Explicit - DC Socket Monitoring (£) but future standard
Precise DC device use provides real-time occupancy, Device adoption, extra data for AC Fusion/Disaggregation
Hardware based - monitoring Standard e.g. Alert Me : 10 sec data, single point of measurement, low cost, self install, large data set already available.
Bespoke monitoring solution: When you need a system that delivers against specific objectives there is often no choice but to design a bespoke system.
Smart Meter: accurate billing data, default is 1/2 hour data, possible to get Khz data for disaggregation (smarts needed in home). Standard, reasonably low cost.
Southend-on-Sea – RHS projectProject to test innovative retrofit energy efficiency technology
45 homes, single location, social landlord
Moixa developed monitoring:
- Electricity (5 channels) – clamp on meter + mains voltage
- Pulse count input for gas meters
- Temperature & Humidity
- CO2 in some houses
- Remote Temp / Light / opening (868Mhz RF)
- Custom – air flow / additional CO2 etc in some houses

What is the data used for?Analysis / atatus / alerts
App specific language,
allows coding for alerts
around very specific
conditions: since there
is a support resource we
will engage individuals in
goal setting.
We will see what works.
Prompts to actionZigbee linked alert light – looked at a few
alternatives with the residents, but this was
judged by them to be their preferred.
Cost comparisonRHS project: £1000 approx per house
Dev cost: £500, hardware £300, install £200
Some interface software costs on top
Alert Me: £50 per house?
Smart Meter: £200 per house? Including Khz?
EST study: £4000 per house approx
But what we need to know is…We have been looking at what you can actually
have an effect on, what parts of the load in a
typical home is there any point in attempting to
modify, as it strikes us this is what you want to
know….
Maybe Probably No Point
DSP Change.. Reasonable?Please turn out lights until day
Please watch later on iplayer?
Please don’t go on-line yet?
How about a cold salad instead?
No?. At least wash a bit later?

We are testing novel retrofitAddress:
- Smart appliances slow adoption
- Low awareness of ‘smart/delay’ features on
appliances
- Fixed use cycles (cleaners, workers, mothers)
With novel retrofit device to improve:
- Awareness
- Inventory of DSM washing appliances
- Solar run hours or shifted hours on DSM
