  2. 2. Quick Overview ● Story ● Meters and bills ● Energy Monitors ● Thermal Imaging08/10/11 Home Energy Event
  3. 3. A Story ● In spring 2010 we moved into our house ● We had the same energy company and tariff as the previous owner ● We have NOT replaced the boiler, the windows or done anything radical to the house yet ● We paid the same monthly direct debit as the previous owner ● How different was our annual bill?08/10/11 Home Energy Event

  5. 5. In One Year... ● Monthly direct Debit went from £160 to £49 ● Rebate of £696 ● They overestimated our gas and electricity by about £100 per month08/10/11 Home Energy Event
  6. 6. What We Did ● Turn central heating boiler thermostat down ● Shortened central heating run time a little ● Replaced all old light-bulbs with modern ones ● Fitted roller blinds behind some curtains ● Fitted draft excluding tape to some leaky doors and windows08/10/11 Home Energy Event

  9. 9. Bill and Meter ● Check your meter once a month and send reading to power company ● Look at the KWh on your bill is it above or below average ● Easy to do you – you only need pencil and paper!08/10/11 Home Energy Event

  12. 12. Energy Monitor ● Current Cost ● OWL ● B&DBC have some to lend ● 1 in the library ● Power companies give them away ● You can buy one for under £5008/10/11 Home Energy Event
  13. 13. Energy Monitors ● Gives you instantaneous electricity use ● Helps calculate base load ● Helps find odd devices08/10/11 Home Energy Event

  15. 15. Thermal Imaging08/10/11 Home Energy Event
  16. 16. Theory ● Everything radiates infra-red or thermal energy ● The temperature of an object gives you radiation of a specific frequency ● A thermal imaging camera converts these frequencies back into temperatures ● The temperatures are displayed as different false colours on the display08/10/11 Home Energy Event
  17. 17. Inside of a House ● Walls and windows should show up warm ● Cold spots means you have leaking heat08/10/11 Home Energy Event

  26. 26. What use is it? ● Should tell you nothing new, but often reveals things you didnt know ● Useful to find where you need to target first ● Can help identify gunked up radiators08/10/11 Home Energy Event
  27. 27. Camera ● Fluke Ti10 ● BDBC own it ● We can survey your house if you want ● Sign up tonight ● we have the camera for the next fortnight08/10/11 Home Energy Event
