Project Background
The new 200,000 sq. ft. building is projected to be the largest stem cell research building in the country. It will house various “open-air” laboratories as well as community gathering spaces to encourage interaction and teamwork.

Project Requirements
Stanford University has their own set of building and energy standards, many of which match or surpass LEED certification requirements. The Stanford central plant supplies chilled water and steam to SIM 1; the making of mass quantites of chilled water and steam greatly reduces energy consumption compared to a stand alone system. All heating and cooling is done locally, each VAV or Phoenix valve has both a chilled water and heating coil, which further reduces energy consumption via zone direct temperature control.

What ACCO Delivered
Whiting Turner contracted ACCO to furnish and install all rooftop and hydronic equipment, and the associated controls system. Additionally, due to the complex nature of SIM 1, ACCO participated in 3-D coordination resulting in a notable reduction of clashes. SIM 1 is a 100% exhausted building due to the contamination standards and requirements of Stanford’s medical research. Thus, there are three make-up air units totaling in 380,000 cfm and 14 complementary exhaust units, largest of which is the general exhaust.
The vivarium exhaust is a pressure sensitive system serving the basement. The SIM 1 basement is a state of the art medical research lab outfitted with animal holding rooms, ultrasound, behavioral testing, procedure, decontamination, and quarantine rooms. In order to maintain Stanford’s strict room pressure requirements, supply and exhaust phoenix valves are installed. Also, the extensive amount of vivarium pipe, ductwork and equipment acted as a design driver for the incorporation of an interstitial floor.
ACCO installed an assortment of other Strobic exhaust systems in conjunction to the vivarium exhaust system.
Coupled with the 100% outside air system is the associated hydronic piping.  SIM 1 has a nominal total of seven hundred cooling and heating coils. In conjunction with the zone control coils there are heat recovery coils in the AHUs, GEs, and VEs.
