Thanks Rob

I did edit the weather file, I made it just for one day, first day in
January;
https://www.dropbox.com/s/iqxjj5u1pls21pv/USA_FL_Tampa.Intl.AP.722110_TMY3.e
pw?m

However the simulation took about two hours. I was surprised to see in the
simulation process that the simulation done for days
In October and November and December:

The output file:
https://www.dropbox.com/s/r6t086gca4soasu/out1.txt?m

The following files will show the results;

Illuminance map`:

Illuminance map2:

Error:
https://www.dropbox.com/s/0vu1t33emw2zzb5/Err.txt?m

Glare:

Global horizontal illuminance

When I did the simulation using radiance, I will get the simulation has
failed.
However, when I just run openstudio without radiance, the run will complete
without any problem:

OK, sounds like it's working. It should go through every hour of the year,
and then it will perform the other calculations and let you know when it's
finished.

The OpenStudio app does not support sub-annual runperiods (yet), so
that will likely not work for you. When you say the sim does not stop,
is it still printing messages to the console window, i.e. still "doing

stuff"?

Ok, then after the annual daylighting sim, you should have seen some
messages about the lighting, and then the glare analysis, and finally
the EnergyPlus messages.

I'm happy to work with you offline on this, if you want to send me any
results or screenshots directly (I assume you've noticed that the list

OK, that's a good thing. How many spaces and illuminance maps do you
have in the model? Currently the program computes each map serially,
i.e. one at a time, so you'll have to wait for it to finish all the
maps before it's fully done. After that, it will do a dimming
analysis and create a lighting load schedule for EnergyPlus, which is
then automatically run as well. It can take some time on a large
model with lots of spaces. But it does sound like things are working for

you.

When it's all done you should see a "finished"
message and hopefully zero errors (there are usually warnings even on
successful runs), and then you can open the eplusout.sql file in
ResultsViewer to review the daylighting.

Keep us posted!

- Rob

P.S. We are rewriting the daylighting script to compute all the
points in the model at one time, rather than space-by-space; this
speeds up the calculation times on large models significantly, and
should be available in the next iteration release which is due out
early next week.

Hi Khalid,

Thanks for all this extra detail! OK, first of all, editing the weather
file to do shorter run periods is not recommended. As you saw, this has no
effect on the Radiance piece (this is because OpenStudio pulls the weather
info from an EnergyPlus pre-process run, which is for an annual
runperiod). Support for shorter runperiods is being put into the app
currently, but I'm not sure when that will be released. Editing the
weather file like you did also caused the "..... Last severe
error=ProcessScheduleInput: Schedule:Compact="THERMAL ZONE 1 LIGHTS
SCHEDULE" has missing days in its schedule pointers" error.

The illuminance map data is goofy; are you looking at data from
radout.sql, or eplusout.sql?

It appears that your simulation is running OK; on a slower system (and
especially on Windows) a two hour run time for an annual sim is not
unusual. I'd try re-running the sim with the full weather file, let it run
its course, and re-review the data. You can also send me your model and
weather file and I can make sure everything looks good.

i.e. one at a time, so you'll have to wait for it to finish all the
maps before it's fully done. After that, it will do a dimming
analysis and create a lighting load schedule for EnergyPlus, which
is then automatically run as well. It can take some time on a large
model with lots of spaces. But it does sound like things are working
for

you.

When it's all done you should see a "finished"
message and hopefully zero errors (there are usually warnings even
on successful runs), and then you can open the eplusout.sql file in
ResultsViewer to review the daylighting.

Keep us posted!

- Rob

P.S. We are rewriting the daylighting script to compute all the
points in the model at one time, rather than space-by-space; this
speeds up the calculation times on large models significantly, and
should be available in the next iteration release which is due out
early next week.

Thanks Khalid,

The results that you have shared seem ok, I'll run your model here later
tonight to confirm. As far as ground reflectance, the default is 20% (this
is applied for any rays intersecting the sphere below the horizon).

However, good modeling practice dictates that you model local ground
features and obstructions, so that local shadow effects are captured. You
can do this in OpenStudio using "site shading surfaces". You first create
a site shading surface group, then draw your local ground planes inside of
that group. You can change the reflectance of those objects by adding
materials to the library that are of the reflectance you want, and
assigning them to the objects' constructions.

Hi Khalid,

Thanks for all this extra detail! OK, first of all, editing the weather
file to do shorter run periods is not recommended. As you saw, this has no
effect on the Radiance piece (this is because OpenStudio pulls the weather
info from an EnergyPlus pre-process run, which is for an annual
runperiod).
Support for shorter runperiods is being put into the app currently, but
I'm
not sure when that will be released. Editing the weather file like you did
also caused the "..... Last severe
error=ProcessScheduleInput: Schedule:Compact="THERMAL ZONE 1 LIGHTS
SCHEDULE" has missing days in its schedule pointers" error.

The illuminance map data is goofy; are you looking at data from
radout.sql,
or eplusout.sql?

It appears that your simulation is running OK; on a slower system (and
especially on Windows) a two hour run time for an annual sim is not
unusual.
I'd try re-running the sim with the full weather file, let it run its
course, and re-review the data. You can also send me your model and
weather
file and I can make sure everything looks good.

message and hopefully zero errors (there are usually warnings even
on successful runs), and then you can open the eplusout.sql file in
ResultsViewer to review the daylighting.

Keep us posted!

P.S. We are rewriting the daylighting script to compute all the
points in the model at one time, rather than space-by-space; this
speeds up the calculation times on large models significantly, and
should be available in the next iteration release which is due out
early next week.

Hi Khalid,

Well one thing's for sure, we need to speed up our code on Windows
machines! I just ran your model and did the full annual simulation in 8
minutes. I have a grad student here at NREL using OpenStudio for a
greenhouse project and his OpenStudio model takes 2 hours to run on his
system, and that one ran in 10 minutes on my laptop. I suspect that all
the multithreading work that Greg has implemented is super awesome, and
that's why Linux and MacOS machines are running all the Radiance stuff a
lot faster than on Windows. We implemented multithreading on Windows using
the Ruby Threads class, but we either implemented that badly or it simply
doesn't work as well as the stuff that's built into Radiance (that does
not work on Windows).

I digress, but I thank you for exposing these things. Anyway, the data all
seems to make sense to me, are you familiar with the ResultsViewer
application for viewing your results? I know you posted some screen shots,
but are you able to zoom in on time periods and make plots? Let me know!

Thanks Khalid,

The results that you have shared seem ok, I'll run your model here later
tonight to confirm. As far as ground reflectance, the default is 20% (this
is applied for any rays intersecting the sphere below the horizon).

However, good modeling practice dictates that you model local ground
features and obstructions, so that local shadow effects are captured. You
can do this in OpenStudio using "site shading surfaces". You first create
a
site shading surface group, then draw your local ground planes inside of
that group. You can change the reflectance of those objects by adding
materials to the library that are of the reflectance you want, and
assigning
them to the objects' constructions.

Hi Khalid,

Thanks for all this extra detail! OK, first of all, editing the
weather file to do shorter run periods is not recommended. As you saw,
this has no effect on the Radiance piece (this is because OpenStudio
pulls the weather info from an EnergyPlus pre-process run, which is for
an annual runperiod).
Support for shorter runperiods is being put into the app currently, but
I'm not sure when that will be released. Editing the weather file like
you did also caused the "..... Last severe
error=ProcessScheduleInput: Schedule:Compact="THERMAL ZONE 1 LIGHTS
SCHEDULE" has missing days in its schedule pointers" error.

The illuminance map data is goofy; are you looking at data from
radout.sql, or eplusout.sql?

It appears that your simulation is running OK; on a slower system (and
especially on Windows) a two hour run time for an annual sim is not
unusual.
I'd try re-running the sim with the full weather file, let it run its
course, and re-review the data. You can also send me your model and
weather file and I can make sure everything looks good.

The OpenStudio app does not support sub-annual runperiods (yet), so
that will likely not work for you. When you say the sim does not
stop, is it still printing messages to the console window, i.e. still
"doing

Ok, then after the annual daylighting sim, you should have seen some

finally the EnergyPlus messages.

OK, that's a good thing. How many spaces and illuminance maps do
you have in the model? Currently the program computes each map
serially, i.e. one at a time, so you'll have to wait for it to
finish all the maps before it's fully done. After that, it will do
a dimming analysis and create a lighting load schedule for
EnergyPlus, which is then automatically run as well. It can take
some time on a large model with lots of spaces. But it does sound
like things are working for

you.

When it's all done you should see a "finished"
message and hopefully zero errors (there are usually warnings even
on successful runs), and then you can open the eplusout.sql file in
ResultsViewer to review the daylighting.

Keep us posted!

When I did the simulation using radiance, I will get the simulation
has failed.
However, when I just run openstudio without radiance, the run will
complete without any problem:

OK, sounds like it's working. It should go through every hour of the
year, and then it will perform the other calculations and let you
know when it's finished.

The OpenStudio app does not support sub-annual runperiods (yet), so
that will likely not work for you. When you say the sim does not
stop, is it still printing messages to the console window, i.e.
still "doing

stuff"?

Ok, then after the annual daylighting sim, you should have seen
some messages about the lighting, and then the glare analysis, and
finally the EnergyPlus messages.

I'm happy to work with you offline on this, if you want to send me
any results or screenshots directly (I assume you've noticed that
the list server rejects posts with attachments?).

OK, that's a good thing. How many spaces and illuminance maps do
you have in the model? Currently the program computes each map
serially, i.e. one at a time, so you'll have to wait for it to
finish all the maps before it's fully done. After that, it will do
a dimming analysis and create a lighting load schedule for
EnergyPlus, which is then automatically run as well. It can take
some time on a large model with lots of spaces. But it does sound
like things are working for

you.

When it's all done you should see a "finished"
message and hopefully zero errors (there are usually warnings even
on successful runs), and then you can open the eplusout.sql file
in ResultsViewer to review the daylighting.

Keep us posted!

- Rob

P.S. We are rewriting the daylighting script to compute all the
points in the model at one time, rather than space-by-space; this
speeds up the calculation times on large models significantly, and
should be available in the next iteration release which is due out
early next week.

Hi Khalid,

THat would be great if you're willing to give it a try! I don't know that there are a lot of people trying out the Linux version. Ubuntu is what we develop and test on, too.

Hi Khalid,

Well one thing's for sure, we need to speed up our code on Windows machines!
I just ran your model and did the full annual simulation in 8 minutes. I
have a grad student here at NREL using OpenStudio for a greenhouse project
and his OpenStudio model takes 2 hours to run on his system, and that one
ran in 10 minutes on my laptop. I suspect that all the multithreading work
that Greg has implemented is super awesome, and that's why Linux and MacOS
machines are running all the Radiance stuff a lot faster than on Windows. We
implemented multithreading on Windows using the Ruby Threads class, but we
either implemented that badly or it simply doesn't work as well as the stuff
that's built into Radiance (that does not work on Windows).

I digress, but I thank you for exposing these things. Anyway, the data all
seems to make sense to me, are you familiar with the ResultsViewer
application for viewing your results? I know you posted some screen shots,
but are you able to zoom in on time periods and make plots? Let me know!

Thanks Khalid,

The results that you have shared seem ok, I'll run your model here
later tonight to confirm. As far as ground reflectance, the default is
20% (this is applied for any rays intersecting the sphere below the

horizon).

However, good modeling practice dictates that you model local ground
features and obstructions, so that local shadow effects are captured.
You can do this in OpenStudio using "site shading surfaces". You first
create a site shading surface group, then draw your local ground planes
inside of that group. You can change the reflectance of those objects
by adding materials to the library that are of the reflectance you
want, and assigning them to the objects' constructions.

Hi Khalid,

Thanks for all this extra detail! OK, first of all, editing the
weather file to do shorter run periods is not recommended. As you saw,
this has no effect on the Radiance piece (this is because OpenStudio
pulls the weather info from an EnergyPlus pre-process run, which is
for an annual runperiod).
Support for shorter runperiods is being put into the app currently,
but I'm not sure when that will be released. Editing the weather file
like you did also caused the "..... Last severe
error=ProcessScheduleInput: Schedule:Compact="THERMAL ZONE 1 LIGHTS
SCHEDULE" has missing days in its schedule pointers" error.

The illuminance map data is goofy; are you looking at data from
radout.sql, or eplusout.sql?

It appears that your simulation is running OK; on a slower system (and
especially on Windows) a two hour run time for an annual sim is not
unusual.
I'd try re-running the sim with the full weather file, let it run its
course, and re-review the data. You can also send me your model and
weather file and I can make sure everything looks good.

Hi Khalid,

the screenshots you attached are from a windows run, did you give up on the OSX side?

Thanks Rob,

I did a re-run for a full weather file, and took about one hour.
I used the weather file for Tampa which come with Energyplus:
https://www.dropbox.com/s/iqxjj5u1pls21pv/USA_FL_Tampa.Intl.AP.722110_TMY3.e
pw?m

The following results are from Radout.sql:

The model I used is the one in Martin message:
(https://dl.dropbox.com/u/27495200/office2.zip\).

Rob, I have a question regarding the reflectance of ground, I did not knew
how to get the reflectance of ground , and how to change such reflectance in
Openstudio.
Thanks

Hi Khalid,

Thanks for all this extra detail! OK, first of all, editing the weather
file to do shorter run periods is not recommended. As you saw, this has no
effect on the Radiance piece (this is because OpenStudio pulls the weather
info from an EnergyPlus pre-process run, which is for an annual runperiod).
Support for shorter runperiods is being put into the app currently, but Im
not sure when that will be released. Editing the weather file like you did
also caused the "..... Last severe
error=ProcessScheduleInput: Schedule:Compact="THERMAL ZONE 1 LIGHTS
SCHEDULE" has missing days in its schedule pointers" error.

The illuminance map data is goofy; are you looking at data from radout.sql,
or eplusout.sql?

It appears that your simulation is running OK; on a slower system (and
especially on Windows) a two hour run time for an annual sim is not unusual.
Id try re-running the sim with the full weather file, let it run its
course, and re-review the data. You can also send me your model and weather
file and I can make sure everything looks good.

OK, sounds like its working. It should go through every hour of the
year, and then it will perform the other calculations and let you know
when its finished.

The OpenStudio app does not support sub-annual runperiods (yet), so
that will likely not work for you. When you say the sim does not stop,
is it still printing messages to the console window, i.e. still "doing

stuff"?

Ok, then after the annual daylighting sim, you should have seen some
messages about the lighting, and then the glare analysis, and finally
the EnergyPlus messages.

Im happy to work with you offline on this, if you want to send me
any results or screenshots directly (I assume youve noticed that the

OK, thats a good thing. How many spaces and illuminance maps do you
have in the model? Currently the program computes each map serially,
i.e. one at a time, so youll have to wait for it to finish all the
maps before its fully done. After that, it will do a dimming
analysis and create a lighting load schedule for EnergyPlus, which
is then automatically run as well. It can take some time on a large
model with lots of spaces. But it does sound like things are working
for

you.

When its all done you should see a "finished"
message and hopefully zero errors (there are usually warnings even
on successful runs), and then you can open the eplusout.sql file in
ResultsViewer to review the daylighting.

Keep us posted!

- Rob

P.S. We are rewriting the daylighting script to compute all the
points in the model at one time, rather than space-by-space; this
speeds up the calculation times on large models significantly, and
should be available in the next iteration release which is due out
early next week.

Hi, Rob
Regarding the sky condition in radiance which come with openstudio, is there
is a way to select the type of sky condition (clear, overcast, ...)
As far as I knew the illuminace map will be generated by EenergyPlus based
on the weather file, is there is a way have the result as a function of sky
type,
as done in daylight factor Calculation?

Thanks

Hi Khalid,

Actually, if you check the "Use Radiance..." box in OpenStudio, then
Radiance will be used for all the daylighting calculations. That's why
it's important to review the "radout.sql" file for the daylighting data,
when Radiance is used.

The sky condition is derived automatically from the weather file. This is
the beauty of what John Mardaljevec calls "climate based daylight
modeling", or CBDM. The sky condition for each timestep is based on the
Perez all-weather sky model, which simply takes direct normal and diffuse
horizontal flux (irradiance or illuminance) as input. It is the ratio of
those two values that dictates the sky condition.

Daylight factors are computed from overcast sky daylight availability
only. This misses a lot of prevalent sky conditions, and as such is a
pretty useless metric for many climates. Hence, the move to CBDM which we
have embraced in OpenStudio (as have Christoph Reinhart, Alstan Jakubiec,
and Kera Lagios with DIVA, Rick Mistrick with the new DAYSIM, et al.).

Are we having fun yet, Khalid? =8-)

Thanks Rob, for the information.
Regarding the Daylight Factor, the following discussion was in a paper I
read several years ago;
  "the average daylight factor .. is a useful design aid which is also
simple to use. Since the daylight distribution and intensity inside the
building will vary with time, whichever sky distribution is used as a basis
for design, then it would seem that great precision in this is
unnecessary.............. I have strong reservations over the provision of
detailed and complex daylight prediction system. What is required, in my
opinion, is a relatively simple system that architects must be encouraged to
use and to combine this with the provision of daylight controls to adjust
the daylight conditions when necessary. Electronic control of the electric
lighting should then integrate the electric lighting with the
daylighting for an energy-efficient design." (David Loe, in the discussion
in reference (1)).
As an architect I believe the daylight factor is more than a metric, and I
do think that its use in different climatic conditions could be improved.

Hi Khalid,

You are right, metric was a poor choice of words regarding the DF. I also
agree that tools should allow architects to quickly estimate the impacts
of their designs, and that controls are crucial to any daylighting system
delivering a cost-effective solution. But lighting controls cannot be
simulated with a DF analysis because the performance of such systems is
highly dependent on actual daylight distributions within a space. This is
the main driver for us in integrating Radiance with OpenStudio (and, in
turn, EnergyPlus).

It is our hope that eventually OpenStudio will make it relatively painless
to do a much more thorough daylighting analysis than EnergyPlus is capable
of on its own.
