<I better suggest you to take the average over one hour of the temperature
data you have collected and then use it in TMY format. >
Converting your 10-minute data into one-hour averages is pretty easy.
Taking that 1-hour data and converting it into pure TMY format is
difficult to say the least. Instead of using this advice, simply use the
Type 9 data reader to read your data at 10-minute intervals and Type 16 to
process the solar radiation. You can then run at timesteps of 10 minutes,
5 minutes, 2 minutes, 1 minute etc.
<Since inside building thermal load at one hour interval is meaningful but
less than that it will have lot of errors so I think TRNSYS is written for
doing hourly calculations. >
That's not true at all. TRNSYS is capable of doing load calculations and
system calculations at timesteps under 1 second. I'm not sure why you
think TRNSYS is just an hourly program - it's not.
