Building Assembly Components
Select the Construction icon from the toolbar to create or edit assembly components. Enter or choose the assemblies that will be used in the construction of your building.
Note: You don't need to document every individual item (e.g. every window) for each assembly in your building, but you should include each different type of window, roof, walls, etc., that is present in your building.
Create an assembly
Add each of the following assemblies, which are available from the list on the Construction page by selecting the Add (plus) icon:
- Window-to-Wall Ratio
- Lighting Fixture Inputs
- Water Heater Inputs
- Operations Inputs
Assembly entries may be edited by selecting the blue "Edit" icon, and/or may be deleted by selecting the yellow "trash can" icon.
Note: Required fields in each of the data entry screens are indicated with a red star (*). If a non-required field is left blank, the tool will infer a value based on the building type, age, location, and assembly type. A unit conversion calculator is available to help with entering assembly thermal property values (e.g. U-Factor, R-Value, area, etc.).
Assign assemblies to building blocks
Every building must have at least one Roof, Wall, and Floor assembly, and every block must have these assemblies assigned. Every surface with a window must have a valid Window-to-Wall Ratio or the total Number of Windows assigned. View the Assign Use Types and Components section for instructions on assigning components to buildings and blocks.
