ACSF's AVF-funded 'Integrated Digital Design Environment for Sustainable Architecture' led by Don Greenberg (JGSM, ARCH, CS), Kevin Pratt (ARCH), and Brandon Hencey (MAE) was featured in the November 2011 edition of the Cornell Engineering Magazine .  The following is an excerpt from “Better Together“:

“Clicking through an array of graphic icons, Nathaniel Jones, M.Arch. ’09, animates the images on a trio of 27-inch monitors in a fifth-floor lab in Rhodes Hall. He clicks on a spinning satellite view of Earth on the screen to his left, then on a map of the United States, and last on a town near Chicago. On the screen directly in front of him, animation turns an architect’s three-dimensional rendering of a geometrically complex house into a sundial of sorts. In less than 60 seconds, the time-lapse display—which incorporates cloud cover based on actual weather patterns in Chicago and even the building materials and room dimensions of the house—simulates the angle of the sun’s rays as they fall on northeastern Illinois, tracing the sun’s arc through the sky over the course of a year and mapping the shadows cast by the house and nearby trees. On the screen at Jones’ right, a second 3-D rendering of the house turns red and blue as rooms heat and cool with the combined effect of sunlight and mechanical systems, while a collection of charts and graphs detail such corresponding data as interior temperature, the building’s energy consumption, and even its carbon emissions.

Known as Sustain, the program simulating this hypothetical building’s performance is the product of collaboration among Cornell faculty in engineering, architecture, and computer graphics. Their goal: promote energy-efficient building design and system engineering by giving architects access to robust, tailored simulations using an intuitive, user-friendly graphic interface early in the design process. The open-source program traces its roots to work begun by computer science professor Don Greenberg ’55 CE, BCV ’58, Ph.D. ’68, when he was appointed founding director of Cornell’s Program of Computer Graphics in 1972…” (read more)
