Buildings.Rooms.FLEXLAB.Rooms.X3A

Models of rooms in test cell X3A

Information

This package contains models of rooms in test cell X3A of the FLEXLAB at LBNL. The following image is a drawing of test cell X3A. 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 X3A. The model for the test cell itself is located in Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCell, the model for the connected closet is located at Buildings.Rooms.FLEXLAB.Rooms.X3A.Closet, and the model for the connected electrical room is located at Buildings.Rooms.FLEXLAB.Rooms.X3A.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 X3A. 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.

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.

Model of LBNL User Test Facility Cell X3A

Information

This is a model for test cell 3A in the LBNL User Facility. This model is intended to represent the main space in test cell 3A. This documentation describes the wall constructions used to model test cell X3A. 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.X3A.

There are 7 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.

An eigth 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. A rationale for why the model is created this way is also provided if it is considered necessary.

Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCellFullBed

Model of LBNL User Test Facility Cell X3A intended for connection with X3B.TestCell

Information

This is a duplicate model of Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCell with the wall separating X3A and X3B removed. It is designed for simulations where both X3A and X3B are used in the simulation to model the whole test bed. If a simulation is created using TestCell from both packages the dividing wall will be modeled twice, so one of the two models used must be created without the dividing wall in the model.

This documentation states only the items which are different from the Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCell model. For documentation on the rest of the walls and connections see that documentation instead.

There are 7 different wall sections described in the model. They are shown in the figure below. This documentation only describes wall section 6.

The different wall sections are entered into the model according to the following table.

Because wall section 6 was moved from datConBou[2] to surBou[2] the reference for other constructions in datConBou have changed as well. These changes are documented in the following table.

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. A rationale for why the model is created this way is also provided if it is considered necessary.

Buildings.Rooms.FLEXLAB.Rooms.X3A.Closet

Model of the closet connected to test cell X3A

Information

This is a model for the closet attached to test cell 3A 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 X3A can be found in Buildings.Rooms.FLEXLAB.Rooms.X3A.

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.

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[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 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. A rationale for why the model is created this way is also provided if it is considered necessary.

Buildings.Rooms.FLEXLAB.Rooms.X3A.ClosetFullBed

Model of the closet connected to test cell X3A intended to be connected to X3B.Closet

Information

This is a duplicate model of Buildings.Rooms.FLEXLAB.Rooms.X3A.Closet with the wall separating this model and Buildings.Rooms.FLEXLAB.Rooms.X3B.Closet removed. It is intended for use in simulations which include both room models to simulate the whole test bed. If the regular models are used the wall separating the closets will be modeled twice, so one model must have the wall removed. This documentation only describes the walls and connections which are different from Buildings.Rooms.FLEXLAB.Rooms.X3A.Closet. For information on the rest of the walls and connections see that documentation.

There are four different wall sections connected to the closet modeled here. They are shown in the figure below. Only wall section 2 is described in this documentation.

The different wall sections are represented in the model according to the following table.

As a result of removing the dividing wall construction, the location of the construction of the floor has changed. The following table shows the old and new location of this wall construction.

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. A rationale for why the model is created this way is also provided if it is considered necessary.

Buildings.Rooms.FLEXLAB.Rooms.X3A.Electrical

Model of the electrical room attached to test cell X3A

Information

This is a model for the electrical room connected to test cell 3A 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 X3A test cell see Buildings.Rooms.FLEXLAB.Rooms.X3A.

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.

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 X3A 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.
