<p>Célia,</p>
<p> There is no right or wrong way to do this. The examples are
meant to show you some possibilities. You can use any of the
methods below that you want. The only thing that matters is that
you end up with a consumption profile that is reasonable and has
the correct units.</p>
<p>In general, Type14 is good for defining profiles that don't have
very many points in them (like a daily lighting load or occupancy
profile). Some other components are designed so that if all you
know is daily totals then they will break up the daily total into
a reasonable subhourly profile. If you have electrical consumption
data from EnergyPlus then I would guess it consists of hourly
values for an entire year and would recommend that you read the
values from a text file using Type9. It is then your decision as
to whether you want to use some Type (Type14 might work) to break
the hourly values coming from Type9 into a subhourly profile.</p>
<p>kind regards,</p>
<p> Davdi</p>
