Multi-objective optimization for structure and energy in the case of multistory buildings with atriums

[摘要] This research shows that a successful workflow exists that compares structural efficiency with operational energy efficiency for buildings that incorporate natural ventilation practices. The parametric model successfully generates floor-framing plans with atriums that are similar to industry standards. Furthermore, this research follows a workflow that allows one to search through a series of building designs to find options that minimize embodied energy while maintaining a minimum usable square footage. The models generated in Rhino can then quickly be analyzed in SimCFD to find the cooling and natural lighting potentials. A review of the results generated in this thesis answers the questions: ;;How far can we push structural optimization while designing for occupant comfort using natural ventilation and buoyancy effects? And 2) What constraints are put on a building;;s global design when cooling and heating is accomplished with natural air flows?;;
