On the Building menu, click Building, and then type in a name for the building you're going to be modelling in the Name box. The name that you type in will be used as the internal file name as opposed to the name of the file, and it's up to you if these names are the same or not. You will see that the default building name is "Building1", which is what you'll be overwriting in this dialog.
If you have used the Building Initialisation Wizard to start the 3D Modeller then you will already have entered the building name, so you will not need to re-enter it again here. If you also selected a weather file in the wizard then the geographical information will have been added to the file for you, including the latitude, longitude, and time zone. Again, there's no need to re-enter this information, you can just skip it and move on.
You don't have to edit the latitude, longitude, and time zone values at this stage in a lot of cases (defaults will be 52 deg N, 0 deg E and UTC +0, where UTC is the universal coordinated time). The default values may not be the ones you will be using for your building, but this is not really a problem at this point, unless you plan to display shadows at a particular day and hour early on. If you are going to do this, or you want to export to a video file, then you will need to set the latitude, longitude, and time zone parameters beforehand.
When you go to export the building geometry to the Building Simulator, the latitude, longitude, and time zone values will be read from the weather file, and again they'll be set for you so you don't have to go back to the T3D and enter them in yourself. Of course the TBD file will only have weather data if it's already been added to the file. If you're not using the Building Initialisation Wizard then the T3D will only be updated when you re-export the building geometry a second time, after you have added the weather file. You will have to export with shading data, and then merge with the existing TBD. If you have chosen a weather file already, when you ran the Building Initialisation Wizard, then you will only have to export the building geometry once, and you can do this with shading data straight away.
| Name | The name of the building or project. You can think of this value as the internal file name. The name will be added to the "Building Name" box in the TSD, on the "Simulation Data" screen. |
| Description | Enter a description of, say, the building, the model, or the
type of study you're undertaking (optional).
The description will be exported to the TBD file, where it will be added to the Building Description box on the Building Summary page. It will also appear in the TSD results file. If you edit the description in the TBD and then re-export your geometry, it will overwrite anything that you may have typed into the box in the TBD. |
| North Angle (degrees) | The angular measurement in degrees, measured clockwise with respect to the Y-axis of the building plan. The arrow will only be visible on 2D views. |
| Latitude | Geographic coordinate specifying the north-south location of
the building on the Earth's surface with respect to the equator,
which has a latitude of 0 degrees.
If the building plan lies between the equator and the north pole then you will enter a latitude between 0 and +90 degrees. If the building plan is between the equator and the south pole then you will need to enter a latitude between 0 and -90 degrees. |
| Longitude | Geographic coordinate specifying the east-west location of
the building plan on the surface of the Earth.
Points with the same longitude will lie on a single line running from the north to the south pole. |
| Time Zone | The time zone for the geographical coordinates of the point on the Earth's surface that is occupied by the building. This can be thought of as the number of hours ahead or behind Greenwich Mean Time (GMT), from -13 to +13. |
