Revit Solar Shading

Welcome to Hyperfine, resources for architects by architects.

This tutorial covers how to properly design a window shading device based on the altitude of the sun. I also preview four methods of modeling shading devices.

This is very helpful, appreciate it. Also the input from Denis R about the adjustment of height.
I sell louvers and sunshades and had always wondered how the values were generated and this info will definitely come in handy.

Ok, so I bought a 2 story house about a year ago that had enormous roof overhangs. (Called it the mushroom house even though the normal climate is hot and humid). Before then I never thought much about the overhangs as in I figured that they were more part of the style than functional. Now, I'm learning about how much those overhangs are keeping the sun (and rain) off the walls of the house. I think its reducing the heat load and reducing paint fading.

thanks for sharing this，helps me a lot 😊

You should put your overhang 10 to 14 inches higher to maximum sun gain (full glass) in the winter and recalculate the extension of the shade. I also like to take for account few hours before and after the sun culmination.

How do you calculate the size of windows

May I know why The Internal Shading Devices & Solar reflection due to adjacent buildings are the two limitations on using to design building envelopes for energy efficiency?
Thank you

I don't understand how you gonna select 75 degree angle 🤔 by screening table or something????

But then, on June 1st the sun is slightly lower in altitude and it's still pretty hot, and now the sun's rays will have penetrated past the glazing, no? You've basically designed a shade that works for 1 day.

Sorry, but this tutorial is useless because it is not representing deeper understanding of the solar geometry needed to be known for constructing a overhang for windows.

At first choosing the pick values (summer and winter solstice) is absolutely wrong because at those positions the sun is only twice a year and are lasting for less then 10 minutes. During the longer period that the windows are exposed to the sun gain (especially in summer) and they need to be protected with overhang, the sun beams have lower altitude and they have azimuth. (exp. May-11 a.m; June 10 a.m and June 11 a.m are more specific)
Some of the next mistakes are:
- analyzing in section with azimuth 0 degree
- where the real north is and etc.

Constructing overhang is much more complicated than any technical person including architects means.
