Gretchen Schimelpfenig is one of those people who seem to fit more into their working week than many of us find time for in a month. She works with greenhouse owners on energy projects and accessing rebates and grants, and runs Cornell University’s GLASE Consortium on greenhouse lighting and control, speaks at green industry conferences, and plays first fiddle in the Hildegard String Quartet. From a Vermont forest home, she manages to combine an engineer’s optimism, with a deep-felt mission to reduce the climate impact of horticulture and the built world.
