TED Expression Builder

The TED Expression Builder is a tool for editing environmental loadings expressions through a dual-pane interface. It allows users to incorporate variables (such as carbon, sulfur, energy, and ash content) and molecular weight constants via drag-and-drop or double-clicking. The tool includes a direct-entry editing box, quick-access mathematical operators, standard editing functions (Cut, Copy, Paste), and a verification feature to ensure expression validity.

• The Expression Builder tool facilitates the editing of environmental loadings expressions by providing a list of available variables—including carbon, sulfur, energy, and ash content—and molecular weight constants that can be added to an expression via dragging-and-dropping or double-clicking.
• The tool's interface consists of two resizable panes featuring an editing box for direct typing, a set of buttons for common mathematical operators, and a toolbar for editing options like Cut, Copy, and Paste.
• Users can validate their constructed expressions using a Verify button before saving the changes back to the environmental effect data screen.
