This package contains models of rooms in test cell X3B of the FLEXLAB at LBNL. The following image is a drawing of test cell X3B. It shows how the different rooms in this example are connected, as well as providing the names used in this example for each of the rooms.
There are separate models for each room in test cell X3B. The model for the test cell itself is located in Buildings.Rooms.FLEXLAB.Rooms.X3B.TestCell, the model for the connected closet is located at Buildings.Rooms.FLEXLAB.Rooms.X3B.Closet, and the model for the connected electrical room is located at Buildings.Rooms.FLEXLAB.Rooms.X3B.Electrical. Each of the models were developed using construction and parameter information taken from architectural drawings. Accurate use of the models will likely require combining all three room models to each other.
The models in this package are intended to be connected to each other to develop a model of the entirety of test cell X3B. Several of the connections are to be made between walls connecting the two spaces to each other. Detailed information on the wall in each test cell can be found in the documentation for that test cell. The connections between each room in the test cell are described below.
| Physical significance of connection | Port 1 | Port 2 |
|---|---|---|
| Heat transfer through the partition wall between the test cell and the closet | TestCell.surf_conBou[2] | Closet.surf_surBou[1] |
| Heat transfer through the door in the partition wall between the test cell and the closet | TestCell.surf_conBou[3] | Closet.surf_surBou[2] |
| Heat transfer through the wall separating the test cell and the electrical room | TestCell.surf_conBou[4] | Electrical.surf_surBou[1] |
| Heat transfer through the wall separating the closet and the electrical room | Closet.surf_conBou[1] | Electrical.surf_surBou[2] |
An example of how these room models are connected to create full test cell model can be found in Buildings.Rooms.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor.

This is a model for test cell 3B in the LBNL User Facility. This model is intended to represent the main space in test cell 3B. This documentation describes the wall constructions used to model test cell X3B. Documentation describing how it is to be combined to other room models to create a model of the full test cell can be found in Buildings.Rooms.FLEXLAB.Rooms.X3B.
There are 6 different wall sections described in the model. They are shown in the figure below.
The different wall sections are entered into the model according to the following table.
| Wall Section Number | Description | Location in Model | Corresponding Layer |
|---|---|---|---|
| 1 | East exterior wall | datConExt[4] | EWal |
| 2 | South exterior wall with windows | datConExtWin[1] | R16p8Wal |

| 6 | North exterior wall and door | Door: datConExt[1] Wall: datConExt[2] |
Door: extDoo Wall: R16p8Wal |
A seventh construction, not shown in the figure, models the ceiling. It is modeled in datConExt[3] using
the layer R20Wal.
The test cell can be configured with several different floor types. The options include radiant conditioning, a slab on grade floor with no conditioning, or a raised floor. Because of this uncertainty in floor design, a model of the floor itself is not included in this model. The user must include a model for the floor in any applications of this model.
Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to models outside of the X3A package. The connections in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary.

This is a model for the closet attached to test cell 3B in the LBNL User Facility. This documentation describes the wall constructions used in the closet. Documentation describing how it should be connected to other models in the package to form a complete model of test cell X3B can be found in Buildings.Rooms.FLEXLAB.Rooms.X3B.
There are four different wall sections connected to the closet modeled here. They are shown in the figure below.
The different wall sections are represented in the model according to the following table.
| Wall Section Number | Description | Location in Model | Corresponding Layer |
|---|---|---|---|
| 1 | West wall connected to X3A.Closet | datConBou[2] | celDiv |
| 2 | North wall on the exterior of the buildings | datConExt[1] | higIns |
| 3 | East wall connected to Electrical | datConBou[1] | higIns |
| 4 | Air space connected to partition wall and door in TestCell model | Wall: datSurBou[1] Door: datSurBou[2] |
There are two additional surfaces which are not included in the diagram. One is the model of the roof. It is
modeled in datConExt[2] using the layer roo. The other is the floor, which is modeled in
datConBou[3] using the layer slaCon.
Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to models outside of the X3B package. The connections in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary. A rationale for why the model is created this way is also provided if it is considered necessary.

This is a model for the electrical room connected to test cell 3B in the LBNL User Facility. Other models are provided for the main space of the test cell and the connected closet. This documentation describes the wall constructions used in the electrical room model. For documentation describing how the room models are to be connected to develop a model of the entire X3B test cell see Buildings.Rooms.FLEXLAB.Rooms.X3B.
There are 4 different wall sections described in the model. They are shown in the figure below.
The different wall sections are entered into the model according to the following table.
| Wall Section Number | Description | Location in Model | Corresponding Layer |
|---|---|---|---|
| 1 | South air space connecting to TestCell | surBou[1] | |
| 2 | West air space connecting to Closet | surBou[2] | |
| 3 | North exterior wall | datConExt[1] | eleExt |

There are two additional surfaces which are not included in the diagram. One is the model of the roof. It is
modeled in datConExt[4] using the layer roo. The other is the floor, which is modeled in
datConBou[1] using the layer slaCon.
Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to rooms which are not in the X3B package. The constructions in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary. A rationale for why the model is created this way is also provided if it is considered necessary.
