Does any one know how to create an INTERIOR solar study? I am trying to see what sun is penetrating through the windows of my building, but in plan view but it casts shadows as if there is no roof. Any ideas? (USING REVIT 2009)

Go to TOP menu, "VIEW-ADVANCED MODEL GRAPHICS" then in the "Sun Position" pick in the right <...> and choose "Single-Day" or "Multi-Day", complete the "Settings" (place, date...), go to BOTTOM in the 3rd button "Shadows On" and choose "PREVIEW SOLAR STUDY" then on top menu pick in PLAY...

Appreciate the help. However i do understand how to do a solar study.

The key points to my question are, INTERIOR and in PLAN VIEW.

When i do a solar study in a ground floor plan view, it does it as if there is no roof on the building.

I would like to do a solar study in a ground floor plan view to see how much light penetrates the windows to the interior of the building.

Any suggestions?

Try using camera views for this.  This should work well for your interior, and you may be able to work it so that you have a camera view looking down at your first floor at the ceiling level so its mimics a floor plan.

I was hoping to internally solar study the whole building at once in plan view not room by room. but thanks anyway. I guess there is no real solution for this.

Has anyone figured out how to do this?  I am trying to do the same thing and also having trouble with the model not recognizing the roof above...

Go to the plan view you want (level 1, 2, site, etc) and follow the step i post before...

Yes, but the results when you do it this way show the interior as if there was no ceiling - i.e. the daylight comes in through the top as well as through the windows and everything is illuminated.  I haven't been able to get it to recognize that there is a ceiling there and show me the shadows cast by it even though it isn't visible in the plan view...

Ok, really i don't figure what do you want because if you want a floor plan by levels, you can do it, if you want all the model by Site plan you can do it anf if you want an Interior by room or open space you can do it, so, what do you really want?

I would like to see the entire plan in one view.  I would like the sun to come in through the windows and have the study show how the light casts onto the floor as the day passes using an animated study.  However, when I do this the way you suggested, the study acts as if there is no ceiling on the space, as if it is a box with no lid.  So there is light everywhere, not just through the windows.

exactly, if you do the solar study in a plan view you don't have the roof or ceiling, then the sun appears to all model, it's logical, but if you put the camera in an interior room the sun only pass by the windows or openings, what do you want is in plan view, all model, the sun to pass only from windows and openings but "He" figure like the plan view have a "kind" of roof and project the shadows, well, "He" don't do it (just like i know the program)....

I don't see how this is "logical"; we need a solar study in a floor plan view to show how natural light will impact the interior spaces without the distortion of a 3D perspective view. If I have in plan view I can see how light impacts the entire space as a whole, instead of 5 or 6 perspective AVI's to portray the entire model. The problem now is a plan view is essentially a slice through the model and for effeciencency when working in the plan it omits or "turns off" the elements above the floor plan, so the reasoning is obvious and understandable.

On the other hand a 3D perpsective view will entail the entire model, but results can get distorted when viewing from a 3D perpsective view so a series of time comsuming 3D perspective animations is required to portray the entire solar study throughout the building. And if you orient your 3D view to a floor plan then all you get is the view from above (arial view) and as soon as you lower your Eye Elevation and Target Elevation down into the building. The spread of the 3D View isn't wide enough to incorprate the entire footprint model and as soon as you expand you view scope it distorts to the point of uselessness.

There needs to be some sort of a "view culling" check box for solar studies in floor plans so we can get accurate interior solar studies. If there already is, please somebody let me know, or if someone has a known workaround that would be greatky helpful as well.

Hi and sorry, but i think just like the program "works" it's LOGICAL what it does,  if you have one plan view (level 1, 2...) it does not matter, and you can see through it like you don't have any roof, ceilling, slab and so one, the program assumes just like that, so, the light (sun) pass through windows, doors and openings, if you don't have any roof or slab it's like an opening, so it's logical "HE" works like that, the problem is, and i quote "There needs to be some sort of a "view culling" check box for solar studies in floor plans so we can get accurate interior solar studies., this is other story, "He" don't do what do you want/need but just like "He" is programmed, the Logical it's "Run"... You can put in the AUGI in Wishlist this issue...

I'm sorry... maybe I can't grasp the concept you are trying to portray here.

When you are in a plan view... it's not like an arial view with the layers (or levels) peeled back until you can see into the desired level below. It's a literal slice through the model (most of the time 4'-0" up from the referenced level)...that's how the program thinks...that's how I think. Here's another "real life' example... if you are standing on the second floor of a five story building does the levels above just magically disappear? When I am standing under a skylight, how can i analyze (in plan view) where the sun's rays will cast on the spaces below in a period of time without a roof or slab or whatever above?
