Visual Imaging in the Electronic Age

An Interdisciplinary Course Bridging Art, Architecture, Computer Science, and Engineering Offered in Fall 2017

The following is a brief description of some of the topics covered in the course, “Visual Imaging in the Electronic Age”. The material is being presented since I have received so many questions regarding the content of this novel multidisciplinary course. I hope the short explanations help. -Don Greenberg

Computer graphics to help streamline green building design

Cornell researchers are developing a computer simulation software for sustainable building design. Team members include, from left, Nathaniel Jones, researcher in the Program of Computer Graphics; Brandon Hencey, assistant professor of mechanical and aerospace engineering; Don Greenberg, the Jacob Gould Schurman Professor of Computer Graphics; and Kevin Pratt, assistant professor of architecture.

Making a building meet sustainability requirements usually involves engineers prescribing fixes -- from building orientation to ventilation systems -- long after the architects have drawn up their designs.

Supported by federal stimulus funds from the American Recovery and Reinvestment Act (ARRA), an interdisciplinary research group at Cornell is creating computer simulation software that would streamline this process, allowing architects to employ sustainable design principles from day one.

The team, which includes faculty from computer science, mechanical engineering and architecture, has received a three-year, $1.83 million grant from the Department of Energy to continue work on their project. Their 3-D simulation tool lets a building designer proactively include such information as temperature, the behavior of light and total energy use at the start of the design process. Such factors should help cut down on the expense of consultation and the labor of going back to change a building's design, said Don Greenberg, the Jacob Gould Schurman Professor of Computer Graphics (also a professor in architecture and at the Johnson School) and one of the project leaders.

"You can have the greatest impact in the early stages of the design process," Greenberg said. "You can make the big changes and see where it's going." Others on the project are Kevin Pratt, assistant professor of architecture, and Brandon Hencey, assistant professor of mechanical and aerospace engineering.

The key to sustainable design is tightly coupling a building to its environment, Pratt said. For example, a well-designed building would use natural ventilation during warm weather to eliminate the use of air conditioning. The simulation tool will allow designers to immediately understand all aspects of the building environment and to cut energy use and, ultimately, the carbon footprint.

"If you're just generically designing a building, you always have the option of putting mechanical systems in and pumping it full of energy," Pratt said. "But that's not really a viable design process anymore."

The collaboration was first funded in 2008 by the Cornell Center for a Sustainable Future Academic Venture Fund. The grant allowed the researchers to create a working prototype of their software. In their next phase of research, the group plans to continue perfecting their system, as well as test it with architecture firms and on campus buildings.

Recent advances in computer graphics technology will likely accelerate these types of simulation computations by orders of magnitude in the near future, Greenberg said. The program now functions on a cloud of computers at Cornell's Program of Computer Graphics running multiple parallel simulations. In several years, said Pratt, most architecture firms will have the computing capability to run such complex models in their offices.

The group is also looking to expand their software to display the simulation results on large-scale multitouch devices, as opposed to just a standard interface. A prototype is being worked on by Lars Schumann, a member of the research team.

The stimulus funds will support seven years of student research, and roughly two postdoctoral associate positions. To date, Cornell in Ithaca has received 159 ARRA awards, totaling more than $113 million.
