Re: [EnergyPlus_Support] Weather file
The weather files are not designed to to this in
EnergyPlus. There are ways to put in different convection
coefficients. As to the differing levels -- Facades can adjust for
different heights.
Objects:
Site:HeightVariation -
\memo This object is used if the
user requires advanced control over height-dependent
\memo variations in wind speed and
temperature. When this object is not present, the default
model
\memo for temperature dependence on
height is used, and the wind speed is modeled according
\memo to the Terrain field of the
BUILDING object.
Site:WeatherStation -
\memo This object should only be
used for non-standard weather data. Standard weather data
\memo such as TMY2, IWEC, and ASHRAE
design day data are all measured at the
\memo default conditions and do not
require this object.
SurfaceProperty:ConvectionCoefficients -
\memo Allow user settable interior and/or
exterior convection coefficients.
\memo Note that some other factors may
limit the lower bounds for these values, such as
\memo for windows, the interior convection
coefficient must be >.28,
\memo for trombe wall algorithm selection
(zone), the interior convection coefficient must be >.1
\memo for TARP interior convection, the
lower limit is also .1
\memo Minimum and maximum limits are set
in HeatBalanceAlgorithm object.
\memo Defaults in HeatBalanceAlgorithm
object are [.1,1000].
But if you want specifics in a weather file or other things that cannot
be adjusted with normal objects, you will probably have to change source
to fit your needs.

Hello,
How am I going to create a weather file that includes all four facades of
building weather data and also all level of the building weather data
into one weather file? And also I do not want EnergyPlus to calculate
CHTC for internal and external of the building. I would like to use CFD
program to calculate and send these values to EnergyPlus because I will
assess high-level building (30 levels at least).
I would like to use my weather file
into the EnergyPlus. I would like to measure weather data ( temperature,
wind speed and direction, solar radiation) on the four facades of the
building and use these data in EnergyPlus. And also I would like to
measure weather data for all levels of the building and use these data in
EnergyPlus. I do not know how to do it. Could you please help me about
that?
Thank you.
