F o s t E r i n g C o l l a b o r at i o n stanford environmental researchers who were once scattered across campus now bump into each other in the hallways of Y2e2. one of the goals for the building was to spur spontaneous interactions and more multidisciplinary collaborations among scholars. A design feature of the building serves as a navigational tool and makes visitors and occupants more aware of the research focus areas located in the building. Various areas of the building are color coded according to the research cluster housed there. red is for climate and energy; blue is for oceans and estuaries; yellow is for land use and conservation; and green is for fresh water. one effort to encourage interaction among researchers is the Wood institute for the environment’s Water seminar, which brings together researchers studying freshwater issues so that they can find out what everyone else is doing. seminars consist of 10-minute presentations on topics such as water regulation in China, reservoir modeling and solid waste management. other researchers affiliated with the Woods institute are studying ways to use river and ocean water to generate electricity. Another project involves developing models to predict where effluent from fish farms would go in coastal areas. They expect the model will provide information to help select appropriate sites for future fish farms.

Active Chilled Beam (ACB) Y2E2 is the first installation of its kind in California and among the largest buildings in the country to install ACB. Heat Pipes in lab Airstream By using a physically separated passive solution that does not depend on moving parts, cross-contamination is avoided and maintenance is reduced. natural smoke Ventilation system California fire-safety codes require smoke control in atria interconnecting three or more stories. Instead of providing the usual mechanical exhaust systems at great expense to the owner, the fire engineers chose to capitalize on Y2E2’s natural ven- High color rendering linear fluorescent lighting illuminates the basement labs.

Cost During design and construction, the team closely tracked and discussed the sustainability cost premium. Individual design elements were broken out from the cost estimate and summed. Its progression started from an early estimate of +9.8% to a final estimate of +0.9% to +4.6%. The ambiguity in the final range reflected the integrated design of components that could not be disassociated from the whole (e.g., atria). Y2E2 will recover the marginal costs of its energy design measures in only four years, which is well under the university’s 10-year benchmark, yielding a 20%+ return on investment. figure 5 Environment Energy used in buildings generates an estimated 98% of Stanford’s carbon emission on campus; the remaining 2% is from vehicles. Annual consumption data for the Computational fluid dynamics image shows fire and smoke distribution. A passive smoke evacuation system capitalizes on Y2E2’s natural ventilation design. 14 HigH Performing Buildings summer 2011
