Summary
Core Theme
This video demonstrates a prototype walkthrough of the "Zone Manager" feature in IESVE software, designed to streamline the process of transferring building geometry and BIM data from Revit, performing load calculations, and sending HVAC zone data back to Revit.

This is a video to demonstrate a
prototypical walkthrough of the zone
manager feature within IESV software.
For the greater context,
I'm initially showing a mockup of a
Revit plugin. This will have more
functions. That's what I'm currently
showing. But for the context of this
video and zone management, what we would
get out of Revit is the gem file. or
geometry and some BIM data. We would
take that data to the VE perform load
calculations and then then send the
loads data and airflow back to Revit by
way of our zone manager.
So within
the VE what that would look like. So,
most will be familiar with room grouping
schemes dialogue. And when you toggle
that to say HBC zones and zone groups,
it currently whittleles down to just one
button here on the left, the nine yellow
squares. And that's currently called
create and edit HVAC zones and zone
groups. So, first of all, that would get
a rebrand and be called zone manager.
And the reason behind that is, of
course, we have a building template
manager and then right next to it, a
tabular building template manager. And
what we were proposing is to have a zone
manager and right next to it a tabular
zone manager. So if you were to launch
the zone manager tool, it it looks
exactly the same as it currently does.
Um again with some rebrand instead of
AHU1 as it currently is that would be uh
rebranded as grouped zones. Instead of
no Apache HVAC system, that would be
called ungrouped zones. and then instead
of unzoned it would be called unzone
spaces and that's exactly what you see
here on the left hand side. So the two
new functions in the zone manager are
here on the right hand side in the
little right panel. The first one is
based on feedback we received from about
eight external
um key accounts
which do not actually use zones. So they
want a quick and easy way to autocreate
a onetoone map from HBC zone sorry from
spaces to HBC zones. So, it's a single
click and that should push you need to
do it down here. There we go. It should
push every space to be a HPC zone and
it's a group zone.
Now, um we've currently included some
uh some bad apples in here whereby you
can see some zones with no rooms in them
and they're flagged as empty. The other
feedback here that can cause an issue
downstream is if you do have HVAC zones
with no rooms in them that can be tricky
or a bit of a pain to to get rid of
them. So there's another just single
click function that wipes every zero
space thermal zone out of your model.
And that's the zone manager. So just two
additional functions and then a little
teaser here to go to the tabular view of
zone manage of zone the zone management
or which may be broadly considered more
zone management. So um I suspect more
folks might actually use the tabedit
view rather than the traditional one
just because there's more functionality
available in here.
Okay. Um,
within the zone management dialogue,
it's hopefully very familiar tabedit
functionality that a lot of V users will
already be familiar with. Rows, columns,
import, export, copy, paste. Nothing too
scary. Um, left to right, you'll see the
hierarchy of zone groups, zones, and
then ultimately spaces that belong to
those zones. And then what will be
listed is the master room of the thermal zone.
zone.
So um what will first of all be
available to you for an import is first
of all to collect the geometry i.e the
gem file from Revit plus BIM data. So
the BIM data is shown in three columns
here. BIM ID, BIM number and BIM name.
Uh that is what some external customers
have told us that they're looking for
from Revit both to get out of it and
also to send data back. The second bit is
is
um actually from our own dev team is
that given the zone manager feature
doesn't really belong to any
application. It's doesn't belong to
model. It doesn't belong to Apache. It
it it can exist in multiple places. Uh
the ability to load in loads data. So
that's what you're seeing in these green
columns over here. Cooling loads and
heating loads. So that's just the
traditional HTG and CLG files available
in Vista Pro. And of course there might
be loads of those and the user should
have an option to choose whichever load
calculations they they want to in order
Okay. So um of course if there is no BIM
data, folks can still use this and and
send data out wherever they want. Um
that's just an option to map the BIM
data that might have come from Revit to
an ISV model.
Okay. In terms of the loads, uh some of
the feedback we got was we don't want to
send 451
CFM or liters per second back to Revit.
We we want to include the oversizing
factor associated to that. So there's a
little percentage value available here.
Some competitor tools have an automated
um functionality for that. So, we're
allowing the user to put in whatever
number they want, be it 10%, 15%, and
that will turn what's shown here as 451
L/s to uh be 519, whereby adding the
15%. To the selected column.
The other feedback we had was some folks
don't want to,
you know, have unusual numbers or
decimal points. They want nice rounded
numbers because that will help them
select grills, diffusers and start
sizing ducts and so on. So the other
function here uh on the left is to round
up the values to the next whatever it is
uh liters per second or CFM value. We
know train trace allows you to do 5 CFM
or 10 C cfm. So we'll we'll just let the
user put in whatever number they want.
Let's say they go to the next 10, then
it'll turn 519 to 520. And this doesn't
change anything in Vista Pro or anything
in existing VE report. You're you're
basically on the way out the door headed
back to Revit and it's just adding some
rounded values or some oversized values.
We did also have feedback that some
folks don't want to do that. They would
prefer to do that in Revit. So these
functions are optional. You don't have
to do them, but you can.
Okay. So next um in terms of additional
columns uh instead of heating and
cooling loads we we heard for from some
customers who are working a lot on
healthcare projects that they wanted to
see specified total supply air flow and
specified exhaust air flow. So we could
potentially add more columns here for
what data folks want to send back to
Revit. Um and of course you can turn
these on or off and they'll appear and
All right. Um,
next is a visualization. So, uh, here on
the left hand side, it's called generate
zone diagram. It's the same little model
viewer, input viewer, uh, icon that
you'll see in the Apache toolbar. It's
just going to add a zoning option, and
it's going to kick off with uh, the
first two are fairly self-explanatory, I
hope, zone groups and zones. So if you
were to select say zones and hit apply
basically that launches model viewer and
you get a nice color-coded diagram with
stories explodable so you can see
multiple floors what the zone diagram
looks like and zone groups might look a
little cleaner if it's you know zone by
floor or something else.
And then the two columns on the right
has been a long-term issue with um
um
I'll say zoning imperfect zoning
practices that result in either
undercooling or overcooling spaces. And
the reason behind that is if there's a
thermal zone with more than one space,
there might only be one thermostat
controlling both or multiple spaces. and
one room is controlling the conditions
in many spaces and that can cause
uncomfortable conditions. So the second
to right column is showing you when the
peak condition occurs and that's I hope
fairly self-explanatory for an hourly
load calculation, hourly cooling load
calculation. The column on the right is
new and basically what this is saying is
that the the non-master room has the
same peak at the same time as the
master. In other words, it should be
fine. There should be no overcooling or
or under cooling in those spaces because
the peaks occur at the same time
and that's in the sort of um deeper
green colored cell. The lighter more
pale adjacent time cells are basically
representing spaces that have almost the
same peak time. So, it's either plus or
minus an hour before or after the master
space or master room or it can be plus
or minus a month at the same time as the
master room is peaking.
Um, so like it's it could be peak at 3
p.m. in June and also peak at 3 p.m. in
July. And that would be deemed
acceptable. It's not like 1 hour away,
but it's adjacent in terms of time
because it's a design monthly
calculation. And then in red is a
non-adjacent time. So we certainly don't
want one room that peaks at 12 midday in
um June to have other rooms that are
peaking at 45 p.m. in September when the
sun is lower and it's western facing.
And that's ultimately going to cause
very uncomfortable conditions in one or
both of those types of spaces. So um
that and that's something that can be
given to a mechanical designer who's not
necessarily a VE user, right? So the the
modeler could send that data back to
um the mechanical engineer who's using
Revit. So for that model viewer that
it's basically going to do the same
thing, give you a visual representation
of of what those two two columns show.
And then last is uh export. So you can
export this table as a a CSV file and
send it back to Revit back to the zone
management feature available in the
