Do I have to take meter readings on a Monday?

No. You can take meter readings on any day of the week. However, SMEasure will interpolate your readings to the Monday as this is the day heating degree days for the last week are imported into SMEasure. Therefore, for the greater level of accuracy for assessing your building’s energy performance we recommend having the habit of taking your readings on a Monday. If you take your readings not on a Monday they will appear in italics to indicate it is an interpolated reading – the actual reading recorded is saved too.
