Can I back-date my building profile if I have old meter readings?

You can back date a profile to August 2007, which is when we have the weather data from. However, unless you have a complete set of past weekly or monthly records for all your energy meters we recommend not backdating your SMEasure and starting fresh. Most energy bills are estimated readings so these are not helpful as SMEasure is based on actual energy use to give accurate feedback. SMEasure will however do a linear interpolation between meter readings you enter to generate any missing weekly readings and consumption values, so this will give you a reasonable picture of your energy usage over time even if you have an incomplete set of readings.
