Floor Information Dialog Box

Building Definition--Floors & Roofs.Floor Information dialog box

See the Common Schedule Dialog Box Features section for more information about how this dialog box works. This section describes the Rename, Find, Previous, Next, New, Copy, Save and Delete buttons.

Default Ceiling Height: The height of the ceiling relative to the elevation of the floor of this floor/level in feet and inches. This is used when calculating the room volume. Room volume is used to calculate air changes per hour.

Floor-to-Floor Height: The height of the outside walls relative to the elevation of the floor of this floor.

Roof

Roof: Whether or not the floor has a roof. If this box is checked, the rooms in the floor will include a roof by default.

Roof Type: The type of roof that the floor has. This field is disabled if the Roof checkbox is not checked.

The list of roof types is set in the Roof Project Schedule command. The Description, U-Value, Type, and Color fields are all based upon the selected Roof Type..

Floor / Ceiling Partition

Floor / Ceiling Partition: Whether or not the floor has a floor or ceiling partition. If this box is checked, the rooms in the floor will include a floor or ceiling partition by default.

Check this box when there is an unconditioned space either above or below the floor. There will be a heat transfer through the area based upon the temperature difference, but there will be no solar load. If you need a solar load, use the Roof checkbox instead.

To model a floor and a ceiling partition, add the u-values for the two partitions together and use that for the U-Value field.

U-Value: The heat transfer coefficient of the floor or ceiling partition.

To model a floor and a ceiling partition, add the u-values for the two partitions together and use that for this field.

Use OSA Temperatures for Other Side: What temperatures are used for air on the other side of the partition.

If this box is checked, the temperatures are based upon the outside air temperatures set in the Project Information dialog box. The high temperature used for the cooling load will change during the day.

If this box is not checked, the temperatures are input directly in the Other Side High Temperature and Other Side Low Temperature fields. The high temperature does not change during the day.

Other Side High Temperature: The high temperature on the other side of the partition used during cooling load calculations if the Use OSA Temperatures for Other Side box is not checked. This high temperature does not change during the day.

Other Side Low Temperature: The low temperature on the other side of the partition used during heating load calculations if the Use OSA Temperatures for Other Side box is not checked.
