Oregon-based ZGF Architects has used a variety of design elements to help minimise the visual impact of a new energy facility on Stanford University’s scenic campus (+ slideshow).
The university’s original campus master plan was conceived in 1888 by Frederick Law Olmsted, the noted landscape architect who designed New York’s Central Park.
The energy complex consists of five distinct programmatic elements: a volume containing an entry court, administrative offices and teaching facilities; a heat recovery chiller plant; a power plant for the medical school and a children’s hospital; an electrical substation; and a service yard.
The new facility covers nearly three acres (1.2 hectares).
The complex contains three massive water tanks that store a total of 12 million gallons (45 million litres) of heated and chilled water.
The firm sought to lessen the plant’s visual impact on the historic campus, which is well known for its Richardsonian Romanesque and Mission-style architecture.
The entry court is situated on the east side and faces the campus, while the substations are on the opposing side and look toward a golf course.
“The massing and arrangement of the various components minimise the overall facility’s impact, with additional visual shielding provided by elegant metal screens,” the firm said.

“The overall architectural expression is one of lightness, transparency and sustainability to express the facility’s purpose.”
The design team incorporated glass, dark steel columns and polished aluminium to create a contemporary aesthetic. To add warmth to an arcade, it used reclaimed wood to form the soffits.
Ample glazing on the administrative and teaching building ushers in daylight and also enables views both into and out of the building. A large photovoltaic canopy provides shade while also generating electricity for occupants.
“Glass-enclosed office spaces and an outdoor, multi-use room float above the entrance, providing views out to central campus as well as into the hub of the facility,” the firm described.
One of the water tanks was painted cardinal red – the university’s official colour – and is visible through a metal screen wrapping the basin.
“At night, lights directed through slender perforated steel columns transform the facility’s centrepiece hot water tank into a red, glowing beacon that serves as the heart of the facility,” the firm explained.
The building “embodies the latest technological advances in heat recovery”.
The plant utilises software developed and patented by Stanford that predicts campus energy loads, grid prices and weather conditions – and then steers “the system to optimal efficiency”. The software also reviews its own performance.
The plant is part of a university-wide initiative to reduce its dependence on fossil fuels.
Other measures include converting the heat supply for all buildings from steam to hot water, constructing an extensive heat-recovery loop system and drawing power from an off-site solar farm.
“This comprehensive Stanford Energy System Innovation (SESI) initiative will eliminate 150,000 tons of carbon dioxide emissions annually, the equivalent of removing 32,000 cars from the road every year,” said the firm.
“Expected energy savings to Stanford over 35 years is $425 million (£300 million).”
Other recent infrastructure projects include a water-cooling facility at Ohio State University by Leers Weinzapfel Associates and a salt shed and garage for New York’s sanitation department by Dattner Architects and WXY.
