Creating a Skylight Element in the Envelope Design: A Step-by-Step Guide

Refining the Envelope Design with a Skylight Element: Detailed Roof Plan Adjustments

Explore the steps involved in fine-tuning building design through the addition of a skylight. This article delves into the intricacies of adjusting roof cuts, establishing dimensions, and creating the base upon which the skylight will sit.

Key Insights

  • The process begins with the adjustment of the roof opening cut to facilitate the skylight opening without disrupting the slope of the roof.
  • Dimensions are critical to the process, with the article highlighting an example of setting a specific dimension at four foot two, while ensuring alignment with the face of the wall.
  • The final steps involve creating a base for the skylight by drawing walls around the outside of the designated roof cut, and attaching them to the roof. The height of these walls may need to be adjusted for optimal results.

The next thing I want to do is finish off the envelope here. And that includes adding a skylight element at this location. So I'm going to jump over to our roof plan and I want to go in and we're going to adjust our roof opening cut here.

And the reason we're using this roof opening cut is because we don't want to mess up the way the roof is sloped here. And so if I adjust this one that we have shown here by just taking it and, say, putting in lines, like you see at this location, then what I can do is I can then use this as the basis for our skylight opening. And so now that's the new roof opening cut.

And I want to set this one dimension since that was pretty arbitrary here. I want to set that to four feet two inches, and then I want you to make sure that you've got this on the face of the wall on both sides here so that it just goes straight back from the curtain wall, and then I'll go ahead and finish the sketch. And so now you can see the roof, nothing changed about it, but we do have this big opening now that we can fill in.

So I'm going to jump back to that roof plan, and then I'm going to use this roof screen type here, and I'll just do create similar, and I'll have it go from roof, but I won't have a base offset. And then to top of parapet, because we're going to attach it to the skylight anyway, and then making sure we're set to finish face exterior. And I'm just going to draw these walls around the outside, and that'll create the base that the skylight's going to sit on top of, and this is clearly much taller than it needs to be.

So the first thing I want to do is I'll just select all three of those walls there, and then I'm going to use the attach with the bottom option. So attach with the base here, and I'll attach that to the roof. Now you can see they're all attached to the base there.

And then I'll take this top offset off for the parapet. Those walls don't need to be that tall. And then I'll add my skylight element in.
