Why?

Reduction in energy use? Reduction in peak demand / load shaping? Improved comfort? Better use of local and distant renewables? Energy security?

In Our Toolbox

Avoidance Thermostats Clocks Anticipation Measurement Storage

Use Cases and Testable Improvements

Bog-standard home such as mine School Community centre

Irregular usage patterns

Extant Controls?

Prefect controls/sensors (UK) LightwaveRF wireless radiator TRVs and boiler

controls (UK) AlertMe/BG, PassivSystems (integrated,

networked: UK) Nest (US) Others with good pedigree such as Honeywell Didn't find: drop-in friendly replacement for normal/setback/frost

PIR+timer 2-wire thermostat!

Nest, LightwaveRFWave, Prefect

Research Results

Close The Door: zero technology, up to 50% savings for shops

PassivSystems: savings of 20--40% with mixture of techniques

SSE/Honeywell trial: peak power demand cut up to 36% (non-domestic)

My 'SuperHome'

Super-insulation, draught-proofing, TRVs, careful use of thermostat, clock, MHRV, improved glazing, only lesser 'smarts' in use at the moment:
