Environmental Performance-Driven Parametric Design Method for General Hospitals Layout Design

Parametric design driven by environmental performance, a design method integrating parametric modeling, environmental design simulation tools, and algorithm-empowered optimization tools, is becoming increasingly popular among architects when designing building complexes, such as residential, office, and campus buildings, during the early stages of design. However, when it comes to the layout planning of general hospitals, this method has not yet been sufficiently employed. Despite this, it is undeniable that such a method could be effective in assisting architects with site planning for typical Chinese general hospital layout design, which focuses not only on functional efficiency but also on passive design aimed at reducing energy consumption. This paper studies the previous applications of this method in building complex layout planning and proposes a feasible alternative for general hospital planning design. Based on the research, an environmental performance optimization parametric planning program was developed and tested in a specific general hospital design scenario. The program is used to generate multiple optimized layouts of the hospital's core buildings, providing valuable results. Optimization strategies for the tool were then proposed based on the analysis of these results. The potential for application in more diverse and complex scenarios is also anticipated
