[Bldg-sim] Design Builder Query

Sun Oct 8 07:51:59 PDT 2017

Thanks

Javed, J. Alstan and David for your responses. However i had tried all
the possibilities,
at-least the ones mentioned by David
of selecting only the bear minimum output options. I have only selected
Annual/Monthly results. Also initially since the simulation
was taking way too long with the model having many zones,I also simulated
the entire building of G+6 floors in two parts ie Gr+3 floors
first by adding adiabatic components above and then 4+6 in part 2. This
took less time and also gave me the necessary output
summary files. Also the model does'nt have any shading elements and also
the WWR is about just 30%. Also no sensors and it has the
default ASHRAE system 8 HVAC for base case.

What is surprising is that i am getting the graphs and basic table summary
results at the end of the simulation however the detail summary
output results is not seen.

Thanks i will keep searching options and also will try putting a ticket on
the website.

Thanks again.

Regards,
Namrata
