Sustainable parking and mobility projects from 2018.
By Megan Leinart, LEED AP BD+C
Once again, 2018 provided a number of advancements in parking and mobility sustainable projects. We continue to see incredible success and progress in sustainable parking planning, design, construction, operations, and technology. People within and outside the parking and mobility industry have embraced the possibilities of incorporating sustainable concepts and strategies into their parking programs and projects—an idea that once seemed impossible to many. More often, owners and developers are incorporating sustainability efforts and certification requirements into their procurement standards, and many vendors and professional service providers are to using these ideas without even being asked. This year, we saw numerous examples of successful sustainable parking and mobility projects. Here’s a look back at just a few.
Stanford Roble Field Parking Garage

As urban campuses grow and thrive, green space becomes an invaluable resource that is often lost to densification. Designing parking with a green roof is one way to have your cake and eat it too. Stanford University has utilized this approach for a number of parking garages on campus, most recently for Roble Field. To preserve this open grass space where students gather, relax, and enjoy recreational sports, the university developed a 1,162-space parking garage underneath it.
Not only did the facility preserve the field, it also virtually eliminated the perception of a below-grade parking structure. To minimize load on the structure, the turf field consists of 24 inches of engineered lightweight soil. In addition to a green roof, the facility is in the process of attaining Parksmart Silver certification. The five-level, below-grade structure provides 52 electric vehicle (EV) charging stations with provisions for an additional 84. It offers active recycling programs, ride-sharing incentives, and a shared parking program. Located near a shuttle stop, the facility adds pedestrian and bicycle linkage and features bicycle parking.
Following the success of this project, Stanford University is pursuing a similar strategy with Manzanita Field, planning an 850-stall parking structure beneath the existing recreational space, featuring basketball and volleyball courts. The Manzanita Parking Structure is also pursuing Parksmart certification.

Cal Poly Pomona’s second parking structure recently earned Parksmart Bronze certification. The 1,800-space parking facility includes a number of sustainable features, including:
- Solar panels.
- Secure bicycle storage.
- Automated, dimmable LED lighting.
- 24 EV charging stations.
- Ride-share parking.
The facility also serves as a stop for four university shuttles, one of which connects with local transit, allowing students to use alternative transportation to reach the campus.
Michael Biagi, university director of parking and transportation services, says, “It’s the best parking on campus by far. It provides the quickest shuttle service to the center of campus, and I think it will provide the best parking experience for our students. The sustainable features of this structure really have our students excited about what can be done with sustainable design.” Biagi highlighted the drought-tolerant landscaping and state-of-the-art rainwater collection system as two of the features that demonstrate the university’s commitment to protecting the environment.
The $41 million structure was built on the site of a surface parking lot, and university officials went to great lengths throughout the process to ensure that the construction and operation of the structure was as sustainable as possible. The contractor used locally sourced concrete, recycled asphalt to pave the surface lot, and hired local labor to shorten workers’ commutes.
Main Street Cupertino Loft Residences Garage
SUBMITTED BY: NAGLE ENERGY SOLUTIONS
Developed by Sand Hill Property Company, Main Street Cupertino Lofts is part of a newly created, mixed-use neighborhood in the heart of Silicon Valley, known as Main Street Cupertino. Main Street Lofts is the second location in the development. The property includes a two-level, below-grade, 92,000-square-foot parking garage.
The mechanical ventilation system for the Lofts garage is powered by two exhaust fan-motor units with a combined 47.5 horsepower powering respective centrifugal fan units.
Per California code, the garage ventilation system must run 24/7 in a subterranean garage with people residing above it. With no means of control in place and running 24/7, the garage-fan motor units would consume slightly more than 333,200-kilowatt hours (kWh) per year, with a correlating peak kilowatt (kW) demand greater than 38 kW.
The facility’s energy solutions provider deployed its demand-control ventilation system, including 23 BACnet-communicating, carbon monoxide (CO) sensors mounted throughout both levels of the garage. The sensors provide instantaneous feedback to the controller, which then relays speed commands to the garage’s exhaust-fan motors, increasing and decreasing motor speeds based on CO concentrations at a given time. This approach, when deployed with the facility’s proprietary and patent-pending control logic, routinely captures kWh and peak kW demand savings in the range of 95 percent—and, in the case of the Main Street Lofts garage, greater.
Since the time of the building commissioning, real-time data logging of kW consumption shows the garage is limiting the motors’ combined kWh consumption to just 9,200 kWh/year, providing a savings of roughly 324,000 kWh a year. Peak kW demand is being reduced by 37 kW/year, all while the property’s large garage ventilation fans run continuously.
Parking and mobility professionals have seen a significant transformation of the industry, with sustainability becoming inherent in every aspect. It continues to be exciting to see all the innovative ideas and products coming out of this industry, and the future promises to be groundbreaking.
