Integrated Design of Perimeter Zones with Glass Facades

摘要

A general simulation design methodology for integrated daylighting and thermal analysis of perimeter spaces of buildings is presented in this paper. The objective is to provide guidelines on how to select glass ratio of the facade, shading device properties and control from the early design stage. The simulation-based approach followed is to create generalized performance indices (at a systems level) as parametric functions of key design parameters (at a component level, such as the glazing area) and then provide the designer with useful informationformaking decisions basedon the integrated analysis results. Integrated performance indices, obtained by the continuous interaction between hourly coupled thermal and lighting simulation, are used as major initial criteria for the selection offenestration and shading design schemes, basedon the balance between daylighting requirements and the need to reduce solar gains. The methodology is general and applies to perimeter spaces of commercial and institutional buildings (particularly offices) for any location, orientation, glazing and shading type.
