  1. What would be 'smart' circa 2012 for our homes, schools, community centres and shops? Damon Hart-Davis 2012/10/30 http://www.earth.org.uk/note-on-smart-heating.html Small-Scale Smart Heating

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

  3. In Our Toolbox • Avoidance • Thermostats • Clocks • Anticipation • Measurement • Storage

  4. Use Cases and Testable Improvements • Bog-standard home such as mine • School • Community centre • Irregular usage patterns

  5. 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!

  6. Nest, LightwaveRFWave, Prefect

  7. 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)

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