It depends a bit on what form the measured results are in. If your
results are in terms of flow rates then you can replace the existing
flow rate (water draw) forcing function in the example with the
combination of a Type9 data reader and some component (an equation
probably) that takes your daily results and turns them into hourly
(or timesteply) results. If your results are in terms of energy then
I would recommend looking at Type682 in the TESS Loads and
Structures Library. This component imposes a load on a liquid flow
stream. You'll again read the data with Type9 and will need to turn
the daily information into the fraction of the load seen at each
timestep. Then the energy rate will be imposed on the SDHW liquid
stream at the appropriate point.<br>

Does any one know how to add in a domestic hot water
