Wallenberg Hall Energy Analysis

Salas O’Brien partnered with Stanford University to conduct an energy survey and analysis of Wallenberg Hall, a four-story campus building primarily used for classrooms and offices.

Our study revealed that Wallenberg Hall could significantly reduce energy consumption through improved zone control and air handling unit control. The Direct Digital Control (DDC) design project, a crucial part of Stanford’s building energy retrofit program, can save substantial energy by scheduling the air handlers off during unoccupied hours, resetting airflow, and supplying air temperature when the demand at the spaces is low. This project followed a design-build process, and the building remained occupied during construction. Following construction, our team provided commissioning services to ensure the equipment functioned properly.
