  1. Creating Sustainability in the Lab - Metro's Sustainability Lab as an Incubator Daniel Lee Washington Metropolitan Area Transit Authority (WMATA), Sustainability Project Analyst Washington, D.C.

  2. Presentation Agenda • 1 • Sustainability Context • 2 • The Role of the Lab • 3 • Projects and Impacts • 4 • Next Steps

  3. Metro at a Glance • Service Area: • 1,500 square miles • 3.9 million population Metrorail 91 stations 117 track miles ~650,000 daily trips Metrobus >11,000 stops 307 routes ~450,000 daily trips MetroAccess ~7,000 daily trips

  4. Performance Targets - Regional • 25%increase in ridership by 2025 • Increase mode share • Increase household and employment growth around transit. • Improve walkability in the ½ mile radius around stations • 10% increase in Greenhouse Gas (GHG) displacement by 2025 • Maximize Ridership • Climate Change • Connect Communities

  5. Performance Targets - Internal • 15% reduction in energy use per vehicle mile by 2025 • 50%reduction in GHG emissions per vehicle mile by 2025 • 30%renewable electricity by 2025 • 100%waste diversion rate (zero waste) • 20%reduction in water use per vehicle mile by 2025 • 100%On-site stormwater management (station/facility) • Energy • Greenhouse Gas • Waste and Supply Chain • Stormwater and Potable Water

  6. The Role of the Lab

  7. Metro Energy Profile CY15 5,482,231,000 MBtu • 321,262,000 kWh • 556,952,000 kWh

  8. Service and Resource Use • Service • Manage resource consumption while delivering safe and reliable service • Pilot cost saving technologies and practices for Authority -wide rollout • Resource Use • Operating Costs

  9. Prove it and Where's the Data • On-site testing of new technology to accelerate acceptance as new standard • Promote a continuous improvement culture.

  10. Projects and Progress Projects and Impacts

  11. Underground Station Chillers • Cooling tower water treatment to reduce chiller water consumption • Average savings of $10,000 per pilot location • Systemwide 20-year NPV savings estimated at $1.5 million

  12. Efficient Track Switch Heaters • Energy efficient rail switch heaters at a pilot yard • 1.6 million kWh (approximately $100,000) of savings estimated from system wide from future rollout at all yards

  13. Tub Grinder • Savings of $50,000 in mulch costs projected in CY16/17 • High employee pride and collaboration with supply chain services

  14. Support Facility Systems • Building Automation System – annual savings $12,000 projected • Shop air compressor upgrade – reduces air leaks and compressor noise – annual savings $3,200

  15. Regenerative Braking Optimization • Evaluate technology to re-use excess braking energy currently wasted as heat • Simulate performance of battery storage and inverters and impacts on the system • Address service expansion and improve traction power distribution system performance

  16. Solar Assessment On-Site Solar Power • Solar assessment as part of roof management program for 935 roofs • Power Purchase Agreement (PPA) for on-site solar carports being developed

  17. Conclusions and Takeaways

  18. Conclusions/Takeaways • Look for different scales of projects and identify an owner • Collect and promote results and consider an awards program • Look at regional contracting opportunities to speed execution
