Case Studies

Channel Islands National Marine Sanctuary - LEED Study

The Channel Islands National Marine Sanctuary Building (CINMS) is a small sized educational building intended for research in ecological science. The building incorporates several energy reducing features including naturally ventilated offices and atrium as well as an ocean based heat pump. Currently the CINMS is under construction with completion planned during fall 2011. An energy model of the CINMS was created to gauge the effectiveness of the building’s energy efficient design. Used for obtaining LEED certification, the energy model is eligible for 10 out of 10 possible LEED points.

Student Resources Building Energy and Comfort Study

Through student approved funding, the student affairs committee at UCSB has made a goal of having it’s building reach zero net energy. This is the first commitment of its kind by any university organization to reach zero net energy that is student funded and organized. As part of this initiative, a study of the UCSB Student Resources Building was performed. Although the SRB is already certified as a LEED silver building and contains many energy-reducing technologies, it was still possible to reduce the building’s energy consumption by 5% illustrating that even buildings with efficient designs have the potential for energy savings.

Engineering Science Building Energy Consumption Study

Using the same methods we used to analyze the Student Resources Building, we have begun to investigate the Engineering Science Building (ESB) on the UCSB campus; one of the campuses largest consumers of energy. The ESB contains offices, laboratories, as well as a clean room. Although many areas of the building are unoccupied at night, the building’s HVAC system operates at constant capacity at all hours. Continuous HVAC operation may not be necessary since certain areas do not have strict operating requirements when unoccupied. Energy savings are possible by examining operating conditions that control the building at lower HVAC capacity.
