Yahoo! co-founder and wife, Jerry Yang and Akiko Yamazaki contributed $50 million towards the construction of the new Environment and Energy Building at Stanford University. The building integrated with existing architecture and supports the university’s commitment to creating a sustainable, environmentally friendly campus.

Dubbed Y2E2, the building’s ambitious energy goal is a 50% greater reduction than called for in ASHRAE 90.1.2004. Additional specs called for a 30% reduction in water usage and that no potable water be used for irrigation.

The importance of this project to the University is clearly stated on a lobby sign:
Most significantly, (Y2E2) is a symbol of Stanford University’s commitment to interdependent systems – and the recognition that these systems are academic, ecological, technological, and social. The Y2E2 building is living proof that all things are connected. And the closer we look, the more these connections are revealed to us.
RUSKIN'S CHALLENGE
  • Develop a passive air management system that provides constant airflow and outside air circulation.
  • Create a recirculating air system that uses natural properties to maintain a comfortable 68º F temperature inside the building.
  • Design an HVAC system that exceeds ASHRAE 90.1.2004 energy reductions by 50%.
OUTCOME
ELC6375DAX Combination louver/Dampers
Ruskin’s combination ELC louver/dampers at the top of the atrium act like a giant siphon and pull up the warm air and discharge out of the building.
ELC6375DAX attributes:
  • Fixed Exterior Blades with Low Leak Airfoil Movable Damper Blades
  • Special Concealed Actuator Side Compartment
  • Modulating Fail Open 24v Electric Actuators
  • Aluminum Bird Screen
ELF Architectural Grilles
Ruskin ELF Arhcitectural grilles provide the inside aethetics at the top of the atrium. The grilles included Kynar ἀnish and were constructed with special spacing requirements to allow for extra lighting.
ELF Grille attributes:
  • Baked Enamel Kynar Finish with 20 year Warranty
  • Flange Frame and Factory Clip Angles
Working with a design team from BOORA Architects of Portland, Oregon and Ove Arup & Partners, an international consulting ἀrm that provides planning, engineering and project management services, Ruskin helped design a passive air management system that takes advantage of one of nature’s basic laws – hot air rises, cold air drops.
RUSKIN'S SOLUTION
Sold by Norman S Wright Mechanical Equipment Corporation, Brisbane, CA.
  • Custom built stacked louvers to exact specifications for each of the four atria.
  • Integrate louvers with a direct digital control system for automated activation.
  • Design louver grilles to match existing architecture.
Tom Edwards, Ruskin President, stated, "Through a creative use of atriums and stacked louvers, we’re able to provide a system that automatically delivers cool air throughout the day."

Known as the "lungs of the building" each of the four atria rises up 89 feet – 24 feet and 6 inches above the roof. At night, when the outside air drops to approximately 60ºF degrees, the louvers open. At the same time a computer analyzes the indoor air temperature and determines which windows within the building to open.

In an interview with KGO-TV, Dick Luthy, Standford Civil & Environmental Engineer Chairman said that process "will let the building naturally breathe and cool down."

This passive cooling system reduces the building’s energy contributing to the overall goal of 50% reduced energy usage.

In order to meet Stanford’s interest in creating a modern building yet retain the classic form of the other structures on the campus, Ruskin provided combination louvers faced with architectural grilles. Combination louvers combine the aesthetic appearance of stationary louvers with positive airflow shutoff capabilities.

The creation of this building was truly a collaborative effort where experts from a variety of disciplines came together and produced something uniquely special.

While the impact of this unique design will be felt daily by those who use the building, the far-reaching implications exceed anything that could be measured on a day-to-day basis.

"We felt this was one of the best investments that we could make for the next generation, and our children," said Yamazaki while standing in one of the trademark atriums during the building’s dedication. "For our children to be able to enjoy and experience what we’ve been blessed with, we cannot afford not to do something today."

The building was constructed to LEED Platinum Standards and won the San Francisco Business Times "Green Building Award" in 2007.
