Mendocino Transit Authority Maintenance and Administration Facility

Ukiah, California

The Mendocino Transit Authority (MTA) staff and bus fleet had outgrown their facility. The maintenance and administrative buildings were 60 years old, overcrowded, hazardous, and wasting energy. MTA needed a new facility to provide sufficient space for all their functions and to accommodate their growth. But they also wanted to greatly reduce their carbon footprint with a new state-of-the-art, sustainable operations and maintenance facility that would support their long-term goal of an electric bus fleet. Enter the next challenge: replace the old facility on their existing site. This required a phased construction so that the MTA operation could continue uninterrupted.

Maintenance Design Group provided programming and master planning to help develop a budget to fund construction of the new facility. The new facility was designed and built to achieve LEED Silver if certified, and includes rooftop solar photovoltaics, radiant-heated floors, evaporative cooling, daylighting, insulation, and electric vehicle charge ports. The result: net electrical use is nearly zero. In addition working conditions are vastly improved.

One of the sustainable features designed into the new facility are photovoltaic (PV) canopies to cover the bus and employee parking stalls. The energy generated from the PV panels is used to charge the electric buses.
