Presenter: D. Michael Utzinger, Professor Emeritus of University of Wisconsin – Milwaukee School of Architecture and Urban Planning

Michael entered the Solar Energy Laboratory at the University of Wisconsin in the fall of 1977. He was a registered architect and his goal was to understand how to design buildings heated directly by the sun. Sandy Klein, his advisor, directed him to begin writing a FORTRAN subroutine for TRNSYS to simulate Trombe Wall performance. At that time simulation was a research technique used to develop design methods: FCHART for solar domestic hot water systems, the utilizability method for general solar energy systems, and, for the Trombe wall, the unutilizability method for passive solar energy systems. Now, forty years later, anyone with skill coding in PYTHON can write a GRASSHOPPER component which can be integrated in RHINO to simulate the performance of a component or a whole building. In this talk, he hopes to reveal how building performance simulation has evolved and where it is headed.
