The current release requires the user to use a text editor or other interface to prepare constructions and materials beforehand. A new construction manager feature will allow the user to add, edit, and delete constructions and materials from an EnergyPlus input file, and manage libraries of constructions. The user will be able to assign a bitmap texture to each EnergyPlus material and render the energy model in texture mode. A “paint can” tool will allow the user to apply constructions to surfaces with a single click.
