Salk Institute for Biological Studies, 1960-1965
La Jolla, California
Cost - $11,415,000 or $27.73/sq. ft.
Cost in 1995 (US$) - $56,231,527 or $136.62/sq. ft.
Stories - Three laboratory levels, each surmounted by a 9 ft (2.7 m) interstitial mechanical space. Surrounding office an mechanical wings are six occupied levels,
with two of the levels being basements at the east end and all six levels exposed above grade to the western side of the sloping site.
Plan - Two long laboratory wings divided by an open courtyard. Uninterrupted laboratory floors measuring 65 ft x 245 ft (19.8 m x 74.7m).
Site Description - Occupying 27 acres on a bluff overlooking a deep ravine running to the Pacific Ocean some 350 ft (106 m) below and west of the laboratory.
Foundation - Basement walls and footings.
Vertical Members - Concrete walls with color admixture.
Horizontal Spans - Vierendeel trusses at 20 ft (6.1 m) on center spanning 65 ft (19.8 m) occupy full 9 ft (2.7 m) height of interstitial spaces. Separation of the complex
into 29 structurally independent buildings adds structural ductility and earthquake resistance.
Equipment - Absorption chillers: 233 ton unit for most of the year. Two additional 750 ton units are available for peak summer weather.
Cooling Type - Chilled water.
Distribution - Dual duct system in North Building with multiple zone mixing boxes controlled by area thermostats, single duct with local reheat coils controlled by
multiple zone local thermostats in South Building.
Duct Type -Rigid metal.
Special Features -Ventilation of lab spaces requires 100% fresh air and a minimum of 12 air changes per hour.
