Though current HVAC systems is more efficient with developments of mechanical technologies or sensor/controllers, architectural design approaches taken to reduce energy needs from HVAC systems are still being explored as the fundamental standpoint.This research suggests a BIM-based parametric design method to establish the BKE (Bio-inspired Kinetic Envelope) system combined with utilization of solar radiation to make buildings acclimate to temperature swings thus minimizing the energy needs.The inspiration refers to the biological thermoregulation that makes organism better suited to its surrounding thermal environments through morphological properties and changes, and then we conducted an iterative parametric design of BIM (Building Information Modeling) to translate the natural model into the kinetic envelopes with the analysis of the selected climate.Furthermore, the research established a prototypical tool for the BKE system.This study reveals the BIM-based parametric design is a very promising method for connecting building behavior and external climatic conditions for studying building energy efficiency.The further step involves an energy simulation for demonstrating the energy performance of the resulting building with BKE sys tem.
