MARTHA HOLLOWELL ORCUTT: Adjusting MEP space volumes
00:04
and Revit.
00:05
HVAC analysis requires work with the full volume of 3D spaces.
00:11
In this video, we're going to review the existing spaces
00:15
and change the height of spaces as needed.
00:19
I'm working in the small Medical Center building in the O1
00:23
ground floor space plan.
00:25
You can see that a half space is applied to each room
00:28
as well as for chassis that can be seen in this plan view.
00:33
First, I need to verify that the system is
00:35
calculating the volume.
00:37
In the Analyze tab, I'm expanding the Spaces and Zones
00:41
panel title, and selecting Area and Volume Computations.
00:46
And the dialog box, I need to verify that Areas and Volumes
00:51
is selected.
00:52
And then I can click OK.
00:57
Now, I'm ready to make sure that all the spaces have
01:00
the correct volume.
01:02
I'm going to open the section running horizontally
01:05
through the building by double clicking on its arrow.
01:07
By default, spaces do not display in sections.
01:11
This section was previously set up
01:13
in the visibility override graphics dialog box
01:16
to show the spaces.
01:18
Now, there are some areas between the floors
01:20
where we need to add spaces.
01:22
But we're going to cover this in a later video on plenums.
01:26
To help us identify what we're working on,
01:28
I'm going to tag all the spaces in this section.
01:32
In the Annotate Tag panel, I'm going to click Tag All,
01:37
select Space Tags, and click OK.
01:41
Now, we can see that most of the spaces extend from the level
01:45
where they were placed to the ceiling of the room
01:47
that they are in.
01:49
Some spaces aren't quite tall enough,
01:51
such as upper lobby on the right.
01:54
And some aren't low enough, such as a pharmacy here on the left.
01:58
An easy way to fix the spaces is to use Controls.
02:04
So I'm going to select the upper lobby space
02:06
and drag the Control up.
02:09
It's OK to be higher than the building elements
02:12
because they are room bounding, and the ceilings and roof
02:16
will stop it.
02:18
Now, I'm going to select the pharmacy space.
02:22
Use the Control and drag it down.
02:26
And you can see that it stops the floor because the floor is
02:29
a room bounding element.
02:32
Now, I might want to be more precise about how far I'm
02:35
dragging these things.
02:36
So instead of using the Control, I
02:39
can actually change it in Properties.
02:41
You can see that it's set up so that the level is
02:45
on ground floor, and I have an upper limit and limit offset.
02:49
But I also have a base offset.
02:52
And I'm going to set that to negative 2 feet.
02:55
So that's precisely now right at the base of the floor.
02:59
I also want to do this to the other two rooms beside it.
03:02
So I'm going to select this space and that one.
03:07
Change the base offset to negative 2.
03:11
And these also extend to the room bounding
03:14
objects in those spaces.
03:16
Now, I know that these aren't the only spaces
03:18
I need to evaluate.
03:20
So what I want to do next is tile the two views.
03:25
I have my O1 ground floor plan and my space section open.
03:31
I'm going to click Space Section and type WT.
03:35
And that opens the two views in tiled mode.
03:39
I'm going to zoom in on the outpatient center.
03:42
I'm going to first work on that area.
03:46
So I can see that in both plan view.
03:49
And I'm going to just drag the section up so I see
03:52
another part of the plan view.
03:55
You might see this warning, there's
03:57
a space tag that's not visible.
03:59
I'm moving it to the space, so it's in good place now.
04:03
So just like the spaces in the rest of the outpatient center,
04:07
these are not low enough.
04:08
I happen to know that this is going
04:10
to be true for all of the spaces in the side.
04:12
They are down a few feet from the rest of the building.
04:16
So I'm going to select all of those spaces, use my filter,
04:22
check Done, select Only Spaces.
04:25
And now, I can go into properties
04:28
and change that base offset for all the spaces to negative 2.
04:36
I'm curious about one room, the staff bathroom,
04:40
because it looks like it's actually in the main building.
04:43
So I'm going to move the section up to that little area there.
04:48
And then I can see that, sure enough,
04:50
here it is the staff bathroom.
04:52
And it stops at the floor because the floor
04:56
is a room bounding object.
04:58
And so even though I have a base offset that's lower,
05:01
it's ignoring that and stopping at the floor.
05:05
Now, let's take a look at the lobby end of the building.
05:10
A lot is going on in here as you can see.
05:14
I want to move the section through this part
05:17
of the building as well.
05:18
So I'm going to start here at the front of the building.
05:21
I've already made my upper lobby, the right height,
05:24
though there is an issue here.
05:26
We'll deal with that in the next video.
05:28
But my lobby, the lower lobby in this case,
05:31
I want that to extend up to the second floor.
05:34
I could use a Control, but it's probably safer
05:38
to come over and change my upper limit no longer to ground floor
05:42
with the limit offset, but to actually specify
05:45
second floor and no limit offset.
05:52
That way, the lobby touches the upper lobby space, which
05:56
is important for our HVAC.
06:01
I'm going to move the section again through the elevator
06:05
this time.
06:09
And again, just going to move a space tag to the space.
06:12
And you can see now, when I look at that, the elevator itself
06:16
has been already expanded.
06:18
So it's in the right space.
06:20
And we've got some plenum spaces will need to deal with later.
06:24
But over here, I have a chase on the lower floor and a space
06:28
on the second in this angled area.
06:31
So I'm just deleting the space on the second floor,
06:35
coming in, assigning this now to atrium roof
06:38
with no limit offset.
06:40
And my chase is filling that space.
06:43
So it's an important thing to check all of these spaces.
06:47
Now, finally, I'm going to come in to the reception area.
06:50
My reception area was the same as the other lobby.
06:53
I want that to be second floor, limit offset of 0.
06:58
And now, I'm ready to do a few more
07:01
things that will help make this particular space more accurate.
