  • 11. An open-source web app for processing, logging and visualising energy, temperature and other environmental data. ●Open-source, downloadable and installable on your own server. ●Specifically designed with processing and visualising energy data in mind. ● Written in php, mysql, javascript, jquery ● Follows MVC architectureopenenergymonitor.org/emon/emoncmsgithub.com/openenergymonitor/emoncms2
  • 12. Input processing Inputs Feeds Power Power power kWh/d to kWh/d Scale, offset Temperature Temperature x 1.1 + 0.2 Voltage x input Power Current
  • 13. EcoBro community energy projectInspiration Saul Griffiths - Wattzon Poptech 2008Saul Griffiths, and David MacKay on sustainable energy plans that add upThe questionCan we make community scale sustainable energy plans?What we did1.) Understand energy use of a group of people interested in sustainabilityIn the Snowdonia North Wales area.Next: 2.) Use this as the foundation for building a sustainable energy plan...
  • 14. The results The group gets 24% of its transport, heating And electric energy from renewable sources Group breakdown National breakdown
