Updated hourly weather data for Copenhagen?

Hi guys,
I have been asked to find weather data for Copenhagen more recent than the epw available (data through 1999). Apparently the DoE last published TMY data in 2001. I believe there must be more recent data available, but I have only been able to find resources such as:
http://www.dmi.dk/laer-om/generelt/dmi-publikationer/2013/ http://www.dmi.dk/laer-om/generelt/dmi-publikationer/2013/
and
http://sbi.dk/en/bsim/climate-data http://sbi.dk/en/bsim/climate-data
I suspect that somewhere there is hourly timestep for weather data more recent. Has anyone found something for the city, or even for the country of Denmark?
Any help would be very appreciated, time is definitely an issue in this case.
Thanks!
Ivan

If you're looking for actual historical weather data for locations around the world,
White Box Technologies has that for over 9,000 locations, starting in 2001. The list of
weather stations with 2014 data can be seen at
www.whiteboxtechnologies.com/ISH2014_Intern_locations.txt .
If you scroll down to Denmark, you'll see there are 29 locations. Most of these locations
will also have data for previous years back to 2001.
If you're just looking for a newer "typical year" weather file for Copenhagen, you might
consider the IWEC2 weather files that were created by White Box Technologies for ASHRAE
in 2010, using weather data down through 2009. The full list of 3,012 IWEC2 weather
locations can be seen at www.whiteboxtechnologies.com/IWEC2_locations.txt , of which 19
are in Denmark.
All the above-mentioned are processed weather files with complete records of temperature,
solar radiation, etc., and come in multiple formats including *.epw and *.ddy.
Please go to http://weather.whiteboxtechnologies.com for more details on either of the
above-mentioned weather files.
Just as clarification, the weather data for Copenhagen that you mentioned on the
EnergyPlus Weather web site is a IWEC weather file developed by ASHRAE in 2001. It is a
"typical year" weather file, but not a TMY, which refers to the "typical year" weather
files developed by NREL for US locations only.

How exactly EnergyPlus calculates the primary airflow rate in coolin

"Solomon Yin" peng_yin@xxxxxxxxx
Hi guys,
I have a question on the calculation of primary airflow rate for series PIU when the cooling is required. A brief calculation procedure is introduced in the engineering manual page 406. My question is what are the other constrains that regulate the primary airflow rate besides the zone load and the minimum primary air fraction that you manually set?
Thanks
Solomon

Annual Glare using Open Studio
Thu Sep 24, 2015 6:51 pm (PDT) . Posted by:

Hi all, I would appreciate your help on this issue
I want to calculate the annual glare (DGPs) of an office model that I'm working with. I obtained the DGP map in the results viewer but I want to know if its possible to obtain the results in figures (excel file) so I can plot my own map.
Additionally, just to confirm: I'm also interested on glare predictions using advanced window systems (BSDF obtained from Window 7 or genBSDF) but, as far as I understand, the use of BSDF in Open Studio is possible now (3 Phase Method) but only with the use of venetian blinds. Then the use of user-defined-BSDF would be implemented in a future version. Is this right, up to this date?
I thank you in advance
Steph.

Steph,
For Openstudio-related questions, you are much better off asking them on
unmethours.com since the developers are actually on it everyday.
Long story short, the numbers are stored in the SQL file, so you need to
query it.
As far as BDSF goes, there's a new field in the OS app for Window Materials
called "Window Glass Spectral Data Set Name, but I haven't used it yet. And
as previously, you can always use an EnergyPlus measure to add your BDSF
constructions to your osm file prior to running E+.
Best,
Julien
