MENDOCINO TRANSIT AUTHORITY, MENDOCINO COUNTY

Ukiah, CA | Complete


This project serves as the core maintenance facility for Mendocino County’s bus fleet. In addition to maintenance bays the project includes shops, storage, fueling, and vehicle wash facilities. The project was designed to minimize operational and maintenance costs, and to provide a strong visual presence from the adjacent freeway.

The structure is defined by a dramatic, “sawtooth” roof with north facing clerestory windows. This maximizes daylight harvesting while providing the ideal orientation for rooftop photovoltaic panels. Prefinished insulated metal panels are attached directly to the metal structure, a simple and cost-effective alternative to a traditional stud wall. These panels do not require painting or maintenance and are one of many sustainable features of this project. The metal panels sit on a base of patterned concrete block walls that provide protection from vehicles. The north wall is constructed of hardwood “rainscreen” that references the local timber industry and nearby lumber mill.

Heating is provided by a radiant floor slab system. The radiant floor slab provides a comfortable work environment and a high degree of efficiency since only the lower, occupied portions of this high-volume space are being heated. Cooling is accomplished by a sophisticated evaporative cooling system, a highly efficient alternative to traditional air-conditioning.
