RE: [EnergyPlus_Support] warnings

BANDAR SERI BEGAWAN is very near Kuala Belait. There will be a slight solar time shift in the results, which would not be significant.

For the ground temperature, you should add the following in the IDF.

!- =========== ALL OBJECTS IN CLASS: SITE:GROUNDTEMPERATURE:BUILDINGSURFACE ===========

Site:GroundTemperature:BuildingSurface,
20.0, 20.0, 19.0, 19.0, 18.0, 18.0, 18.0, 18.0, 19.0, 19.0, 20.0, 20.0;

If you have a large building, you may increase these to 22.0°C.

If the building is naturally ventilated, they may be increased to 24.0°C.

    Notice that the value is higher for January and December. The minimum is around June.

    This is because the JUne month is Winter in Australia, and the ocean current surrouonding KUALA BELAIT iz from the South. The trend of the values are listed in the .stat file for BANDAR SERI BEGAWAN weather file.

   I first noticed this from working with Mr. Ooi at UNIMAS, Kuching.

Subject: [EnergyPlus_Support] warnings

Hi everyone,

Thank you very much for the help with previous issue SketchUp and E+. All suggestions were very helpful and highly appreciated!

I am doing simulation in tropical region, but weather file is only for capital city and houses located in urban area.Therefore Eplus give me following warning:

** Warning ** Weather file location will be used rather than entered Location object.
** ~~~ ** ..Location object=KUALA BELAIT
** ~~~ ** ..Weather File Location=BANDAR SERI BEGAWAN - BRN IWEC Data WMO#=963150
** ~~~ ** ..due to location differences, Latitude difference=[0.36] degrees, Longitude difference=[0.71] degrees.
** ~~~ ** ..Time Zone difference=[0.0] hour(s), Elevation difference=[92.11] percent, [175.00] meters.

Do I need take it into account? If yes, any suggestions?

Second question regarding "Ground temperature".The house have the exterior floor with outside boundary condition Ground, after running simulation I've got warning:

** Warning ** GetSurfaces: Surfaces with interface to Ground found but no "Ground Temperatures" were input.
** ~~~ ** Found first in surface=15183A
** ~~~ ** Defaults, constant throughout the year of (18.0) will be used.

Where should I include Ground temperature, or it should be contain in weather file?

Thanks in advance.

Best regards, Veronika
