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?
