Wall Master Schedule

The wall master schedule contains the wall types that might be used by a company on a project. See the Master and Standards Databases section for more information about using master databases.

To create and modify wall types in the master schedule, go to

DM HVAC->Building Definition->Schedules->Wall Master Schedule

Wall Master Schedule Dialog Box

Building Definition--Walls.Wall Master Schedule 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.

See the Import from Project Schedule section for more information about importing walls from a project to the master database.

Current Group: The active wall type group is listed here. All the wall types that are created and modified will be associated with this group.

Select Group: Press this button to open the Wall Master Schedule Groups dialog box. The group selected will become the current group. See the Common Groups Dialog Box Features section for more information.

Wall Type: The name of the wall type.

U-Value: The heat transfer coefficient of the wall.

ASHRAE Wall Type: The type of wall used to determine the rate of solar heat transfer through the wall. The CLTD method is based upon 15 different walls types, numbered from 1 to 16 (skipping 8). The walls are roughly ordered so that type 1 is the lightest construction and type 16 is the heaviest. Heat is transferred more quickly through light walls. Heavy walls absorb the heat and release it into more slowly into the room.

The wall types are defined in Table 33A in 1997 ASHRAE Fundamentals Handbook, pages 28.46 - 28.48.

Color: The color of the wall. It is recommended by the CLTD method that you choose Dark and not adjust the wall load based upon the color.

Light: The wall is a light color. The cooling load will be scaled by 50% when this color is selected.
Dark: The wall is a dark color. The cooling load will be taken directly from the CLTD table with no scaling.

Description: A longer description of the wall type. Displayed when selecting the wall type and in the Wall Types table of the Building Definition print out.
