Kaiser Permanente Market & Valentine Specialty Medical Office Building, California

Tetra Tech’s High Performance Buildings Group provided LEED consulting, energy analysis, daylight modeling, mechanical, electrical, and plumbing (MEP) engineering for the new Kaiser Permanente Market & Valentine Specialty Medical Office Building (MOB), which is expected to be the largest Kaiser Permanente office building in Ventura County, California.


  • Size: 56,000 square feet
  • Client/Owner: Kaiser Permanente Foundation Health Plan
  • Architect: Taylor
  • Contractor: McCarthy
  • Completion Date: 2018


Membership in that area has grown since Kaiser Permanente acquired a local medical group, and the additional capacity at Market Street now meets the needs of the community.

In addition to an urgent care unit, the 56,400-square-foot MOB houses obstetrics-gynecology, orthopedics, podiatry, plastic surgery, gastroenterology, hematology, oncology, general radiology, ophthalmology, optometry with optical dispensing, blood draw, an infusion center, and a pharmacy. The design allows for a future 16,000-square-foot expansion to double the capacity of the provider offices and exam rooms.

Tetra Tech's engineers chose highly efficient direct expansion rooftop air handlers to minimize energy consumption of the building. The internal spaces are served by variable volume terminal units that allow energy savings, and constant volume terminal units that maintain patient and staff safety in critical areas of the facility. Internal heating is provided by heating hot water with high-efficiency condensing-style boilers. The facility uses a demand response sequence to lower the energy usage of the facility by turning off non-critical equipment when the local utility is stretched thin on capacity.

Kaiser Permanente Market & Valentine Specialty MOB was named California's Healthcare Project of the Year by Engineering News-Record in 2018.
