Energy / context monitoringTSB DSM/Smart Power Projects, Southend - RSH Chris Wright, CTO Monitoring workshop – 13th Nov 2012, Cambridge www.moixatechnology.com

Software based – DC monitoringInference - Network Scan (MAC address tracking)Explicit - DC Socket Monitoring (£) but future standardPrecise DC device use provides real-time occupancy, Deviceadoption, extra data for AC Fusion/Disaggregation
Hardware based - monitoringStandard e.g. Alert Me : 10 secdata, single point of measurement,low cost, self install, large data setalready available. 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.Bespoke monitoring solution: Whenyou need a system that delivers againstspecific objectives there is often nochoice but to design a bespoke system.
Southend-on-Sea – RHS project Project 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 / alertsApp specific language,allows coding for alertsaround very specificconditions: since thereis a support resource wewill engage individuals ingoal setting.We will see what works.
Prompts to actionZigbee linked alert light – looked at a fewalternatives with the residents, but this wasjudged by them to be their preferred.
Cost comparisonRHS project: £1000 approx per houseDev cost: £500, hardware £300, install £200Some interface software costs on topAlert 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 actuallyhave an effect on, what parts of the load in atypical home is there any point in attempting tomodify, as it strikes us this is what you want toknow…. Maybe Probably No Point
DSP Change.. Reasonable?Lighting Please turn out lights until dayAudio Please watch later on iplayer?VisualICT Please don’t go on-line yet?Cooking How about a cold salad instead?Washing No?. At least wash a bit later?
We are testing novel retrofitAddress:- Smart appliances slow adoption- Low awareness of ‘smart/delay’ features onappliances- 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
