Abstract
The purpose of this study is to suggest the concept of an integrated unit and to develop integrated units considering the layout of luminaires and diffusers in workspace. An integrated unit can be defined as a planning unit which satisfies the environment comfort criteria of workspace. Integrating process of each unit was proposed by considering the current workspace planning process. Luminaire and diffuser types are classified by surveying the workspace of the domestic and foreign office buildings. Several lighting units and air-conditioning units were developed by visual and thermal simulation, and integrated units for various architectural module which satisfies the visual and thermal comfort criteria were drawn from those units.
