It is through Metro's projects and programs that we realize our vision, policies and plans into practice. What follows are a few of our recent and noteworthy efforts.
Reducing Energy Consumption
Building operations support over 1.2 million weekday rail and bus transit patrons. Despite aggressive expansion of the rail system, we are committed to reducing our energy consumption guided by our new strategic plan, Moving Beyond Sustainability . Some featured efforts are described here:
Union Station Gateway Building and Parking Garage Lighting Retrofits
The Metro headquarters building is preparing for a major LED lighting retrofit. The Gateway parking garage is also being retrofitted with new LED lamps to replace the existing garage lighting. After installation, on-going measurement and verification will be pursued in order to track electricity and cost reductions resulting from this initiative.
Solar Power Purchase Agreement 1.72 MW Installation
A power purchase agreement (PPA) is being executed to install photovoltaic structures at four (4) bus and rail divisions. The scope of the PPA will be installed upon completion of roof repair projects for Division 11 and 22. The entire project is expected to install 1.73MW in capacity and projected to avoid nearly 3,000,000 kWh from being purchased from Southern California Edison.
Transportation is a major contributor to reducing greenhouse gas emissions. Keeping the air clean during construction is an added challenge. We are leading the way:
Metro Green Construction Policy Program
In order to mitigate air emission impacts, Metro’s Green Construction Policy requires Metro’s contractors to start using cleaner vehicles and equipment. The policy, established in 2011, requires Metro’s contractors to use less polluting equipment and reroute construction traffic away from schools, daycares, playgrounds, and hospitals.
Managing Metro's Water Use
Portable water consumption is expected to increase due to Metro's Twenty-Eight by '28 Initiative, featuring transit and facility expansion projects set to come online by 2028. To mitigate anticipated increases in water consumption, we are implementing several strategies to reduce potable water consumption. We are also looking for wats to increase runoff infiltration and capture capacity for stormwater. Some featured efforts described here:
An innovative stormwater management technique that allows water to pass freely through soil layers so it can replenish groundwater, while providing a usable and lasting surface for vehicle parking and operations.
Bus Wash Water Conservation
The Diamond Seal System (DSS) will be applied to buses in order to reduce dirt and residue build-up, allowing washing schedules to be reduced to one day per week. Once the DSS system has been deemed effective and the pilot program has successfully shifted to the new washing schedule, this system will be implemented across the entire bus fleet.
Designing and Building to a New Standard
Metro is developing new ways to work with our contractors as we encourage them to design to the highest sustainability standards feasible.
Metro Sustainability Program
The Sustainability Program guides the design and construction of world-class projects by incorporating sustainable elements and CALGreen requirements into the design and construction process for Metro capital projects.
Setting the Standard
Metro aims to continuously improve our practices by monitoring our operations and construction efforts against compliance regulations.
Construction Environmental Management System (C-EMS)
A program certified to the ISO 14001:2015 standard Metro uses to monitor and improve compliance performance utilizing the Plan-Do-Check-Act cycle.
