Hi Ian

the "do not integrate" must be set in prj before you simulate. When you
change the time step (number of time steps per hour), prj asks if every time
step or hourly values should be saved. Here you say "every time step".

Oversizing may influence the simulation depending on time step. If enough
power is available, any temperature change can be egalized in one time step.
If not enough power is available, it may take more than one time step. Of
course, this will also depend on time steps.

 Hello Achim (& Fellow ESP-r's),

Thanks for the below explanations.

1)  My control is super simple for this model > Basic Control > Heating
Set-point of 19 C. How does the heating system work? Would the size (or more
specifically the oversizing) of the heating system affect the basic control?
Can it be regulated or is it either "on" / "off"? Would oversizing account
for the below fluctuations? 

You mentioned  "do not integrate time step values" for the results file. Is
this option available? If it does exist can you help me find it? What I do
to display information is: 
> Results Analysis > Time-step reports > preformance metrics > heating /
cool / humidify > Sensible heating load

> I output the information to a file.  

None of the following Data Display options give me what I want: 
> Data Display options: (currently variable)
- integrated - 
- rate of change of variable - 
- variable - 
- continue - 

2) Thanks for the clarification ... CSV & XML are always produced with the
H3K option ... I think there still exists a menu sensitivity in the Native
Windows Version that does not appear in the Linux Version. (This one is
probably for Jon). 

Regards,

Ian

Assunto: AW: [esp-r]  H3K / XML / CSV Output

Hi Ian

some thoughts:

1) res gives output for either timestep values or hourly, depending on your
choice in prj. The h3k output, however, is always the time step. The switch
"time step averaging" does not do what one might expect (at least I did),
namely average the time steps to an hour. It averages the run time "present"
and "future" values for each variable before output.

So, the only basis for comparison would be "do not integrate time step
values" for res.

What kind of control do you have?

2) h3k output is controlled by the input.xml file. Via the menu you can
(basically) set this up. As far as I know, both .csv (time step  results)
and .xml (summary results) are always generated.

Best
Achim

 Hello Fellow ESP-r Community, 

1) I have recently been playing with the H3K / XML / CSV Output on the ESP-r
native windows version. 

I ran the simulation at time steps of 20 minutes. When I look at the results
file > sensible heating load ... I get a total value and list of values that
look reasonable.
#Time BasseHeatInj(kW)
'00:30:30'       3.44
'01:30:30'       3.76
'02:30:30'       3.94
'03:30:30'       4.00
'04:30:30'       3.9!  5
'05:30:30'       3.93
'06:30:30'       3.80
'07:30:30'        3.73
'08:30:30'       3.74
'09:30:30'       3.75
'10:30:30'       3.70

When I look at the CVS file the total supplied energy is the same as the
above results file, but the individual hourly values fluctuate considerably
and they do not match the sensible hourly heating requirements of the
results file.
> building/all_zones/supplied_energy/net_flux: Net heat/cooling supplied to
the building (all zones). (kW) 

2.77
4.75
3.13
4.87
3.03
4.83
2.78
4.68
2.79
4.71
2..70
4.50

I have confirmed that these fluctuations occurs with time-steps of 1 hour,
30 minutes and 20 minutes. It!   also occurs on ESP-r Linux version. Any
ideas? 


2) When I go into the >Integrated Simulation >H3K Reports Configuration the
menu seems to have a several sensitivities: 
- I can enable the H3K Reports but I  cannot dis-able the reports (i.e. H3K
Reports >> enabled) ... normally a second click should disable the reports
and close the menus (i.e. H3K Reports >> disabled).
- There is no option of the output i.e. CVS or XLM (i.e. XSLT Formatted
output) ... it seems to output both files at the same time. Is this
intentional? 
(There could be other sensitivities in the menu that I am unaware of because
I don't normally use the ESP-r Linux version.)

Ian
