Just select Design > Energy Evaluation, and the Automatic model geometry analysis function automatically turns the ARCHICAD building information model (BIM) into input for building energy modeling.
Before the Energy Model Review palette appears, ARCHICAD analyzes the visible structures and openings according to their orientations and positions relative to the zones that represent the internal spaces, then automatically generates the space boundaries. These space boundaries make up the contents of the Structures and Openings lists of the appearing Energy Model Review palette.
Note: When Energy Evaluation is selected for the first time on a project, ARCHICAD automatically puts all visible Zones into a default Thermal Block. This represents a single thermal block (simplified) building energy model.
See Create Thermal Blocks for details on how to define a detailed energy model that contains multiple thermal blocks.
Use the Update Energy Model Review command on the upper left corner of the Energy Model Review palette after redefining Thermal Block data, or after altering the geometry of ARCHICAD Structures or Openings boundaries. This function regenerates the space boundaries, ensuring that the energy mode reflects the up-to-date state of the ARCHICAD model.
