2017 AIA Institute Honor Award Winner in Architecture
Stanford University’s campus is forested, gorgeous, and very, very big. Eight-thousand acres in all, the great swath of Northern California landscape known as “the farm” is home to dozens of buildings, all of which have to be powered, plumbed, heated, and cooled. Such quotidian technicalities could easily be hidden away in a modest shed, but Stanford’s new Central Energy Facility puts them front and center.
Designed by Portland, Ore.’s ZGF Architects, the facility plays up its innovative, ultra-efficient technology with vivid colors and dramatic material contrasts: On the campus-facing side, a glass volume housing administrative offices abuts a concrete block with generators, chillers, and cooling towers—the whole ensemble topped by a series of photovoltaic sunshades held aloft on metal piers. A mechanistic showcase recalling the grand old radicalism of the Centre Pompidou, the building’s pipes are painted a brilliant blue, and its thermal tanks a blaring red. In a softer, more contemporary touch, the shade structures shelter landscaped outdoor spaces with indigenous plantings.
But what the project represents is even more striking than the building itself: The facility is just one part of the Stanford Energy Systems Innovations, a massive infrastructural initiative expected to improve campus energy performance by 75 percent. And to prove how central the initiative is, Stanford has made the building part of its campus tours—another lure for prospective students alongside the original Mission-style architecture and mascot-inspiring evergreens.

Project DescriptionFrom the AIA:
At the heart of Stanford University’s transformational, campus-wide energy system is a new, technologically advanced central energy facility. The system replaces a 100% fossil-fuel-based cogeneration plant with primarily electrical power—65% of which comes from renewable sources—and a first-of-its-kind heat recovery system, significantly reducing greenhouse gas emissions, and fossil fuel and water use. The facility comprises a net-positive-energy administrative building, a heat recovery chiller plant, a cooling and heating plant, a service yard, and a new campus-wide main electrical substation. Designed to sensitively integrate into the surrounding campus, the architectural expression is one of lightness, transparency and sustainability to express the facility’s purpose.
2017 AIA COTE Top Ten Jury Comments:
This project fulfills a carbon-neutral strategy for Stanford and houses a central plant and facilities building. The facility demonstrates a long-range climate and energy plan in action. It transforms what would be a typical unappreciated energy plant into a classroom and a moment of architectural joy. A naturally ventilated, daylit work environment is provided for facilities staff who would normally be in a windowless basement. It sets a high bar for a university to provide national environmental leadership and design excellence.
