Still Solar Studies Based on Location
You can set up solar studies for the same building model in different locations. For example, if the same
retail store will be constructed in Los Angeles and London, change the Place setting at the project level, and
then export a solar study for each city location.
Use this procedure to specify the location settings for a still solar study after performing the initial steps to
create the study .
To create a still solar study based on location
1 On the Still tab of the Sun and Shadows Settings dialog, under Settings, select By Date, Time
and Place.
The Place defined at the project level displays.
2 To change the place, do the following:
a For Place, click .
b On the Place tab of the Manage Place and Locations dialog, select a city.
The latitude and longitude for the specified place display.
c Enter values for Latitude and Longitude if you need precise solar study information, or
accept the predefined values if you want a close approximation based on the nearest city.
NOTE If you enter values for Latitude and Longitude, no value displays for City. When you click
OK, the value for Place in the Sun and Shadows Settings dialog is User Defined.
d If you want Revit Architecture to calculate whether to use daylight savings time, select
Automatically adjust clock for daylight savings changes.
e Click OK.
3 In the Sun and Shadows Settings dialog, enter a date and time for the solar study.
4 To specify the level to be used for shadow display, select Ground Plane at Level, and select the
level.
When you select Ground Plane at Level, Revit Architecture casts shadows on the specified level
in 2D and 3D shaded views. When you clear Ground Plane at Level, Revit Architecture casts
shadows on the toposurface, if one exists.
NOTE This option does not affect shadows in rendered images.
5 To test the new sun and shadow settings, click Apply.
6 When you are finished setting up the solar study, click OK.
Still Solar Studies Based on Azimuth and Altitude
Use this procedure to specify the azimuth and altitude settings for a still solar study after you perform the
initial steps to
create the study .
To create a still solar study based on azimuth and altitude
1 On the Still tab of the Sun and Shadows Settings dialog, under Settings, select Directly.
2 Enter values for Azimuth and Altitude.
