[esp-r] Re: Simulation with temporal file

[Jon Hand]

The sky temperature option in the temporal file is work-in-progress.  It is
not yet connected to the solver.  We should probably update the
documentation to make this clear.  It might not take a lot of work
to use the data - and no one has yet done it.

There are several sky temperatures calculated within ESP-r (there is a trace option
in the simulator that will report on these). Currently you would have to alter the
source to enable one of the alternative sky temperature methods.

The SURTM is design to allow you to plot/report measured values so that it
is easier to compare them with simulated values.  The simulator does not use SURTM
items. The results analysis module knows how to include them in reports or graphs.  
It looks like we need to revise the help messages further to make this clear.

Surface temperatures are the result of heat flows (the energy balance at each
surface) rather than an input value. 

If you have specific sky temperature data do you have matching dry bulb and
humidity data?

Subject: [esp-r]  Simulation with temporal file

Dear all,

I'm trying to simulate my model with calculated sky temperature.
So I created a temporal file to apply calculated value and associated it in my model,
but the result, e.g. roof surface temperature, didn't change anything.

I tried another option(SURTM-measured surface temperature) with all zero value and also different model in training>>basic,
but the result was the same.

Did I miss something?

I attached what i created with 'bld_basic' model in training.

I got ESP-r from 'ESP-r Central' and installed it with gcc-4.4 in Ubuntu 10.04LTS.

Thanks in advance.

Kind regards,
