A Hierarchy of Architectural Design Elements for Energy Saving of Tower Buildings in Korea Using Green BIM Simulation

Table 1

LOD step contents.

LOD	Modeling level of the BIM model by LOD
LOD 100	Mass at the level of planning work
	Shape, volume, and type of the building
	Determination of the area, height, volume, position, incense, etc., of the entire building
LOD 200	Planning step that concept is embodied
	Shape, space program, space planning, and spatial relationship definition
	Decision of general architecture general system
	Planning of approximate floor area, coverage ratio, and floor area ratio, number of floors, floor height, main structure, envelope structure, and equipment system
LOD 300	LOD 200 steps to determine the outline of the concrete contents
	Determination of building systems, including detailed installation elements
	Modeling of all architectural elements
LOD 400	Modeling steps for actual construction
	Model the size, shape, quantity, etc., of all determined systems
	Model all the elements related to construction, fabrication, and assembly, including details, members, structures, equipment, piping, and wiring
LOD 500	The LOD 500 model is the same as the completion model (the modeling data are the same as the actual building)
	Maintenance and overall operation of the building
