Parksmart is the world’s only rating system designed to advance sustainable mobility through smarter parking structure design and operation. Developed by industry experts, Parksmart offers a roadmap for new and existing parking facilities to use innovative, solutions-oriented strategies. Points are awarded to parking structures for forward-thinking and sustainable practices in three categories: management, programs and technology structure design.

Parksmart garages use energy-efficient lighting and ventilation systems, guidance systems that help drivers find parking faster, idle-reduction technologies, electric vehicle fueling stations, car sharing, bicycle parking and storm water management practices. The high-performance structures, technologies and practices of Parksmart-certified garages reduce energy consumption, maximize performance, and minimize waste, as well as encouraging biking, car sharing, carpooling and alternative fuel vehicles.
