4. Energy Exchange : Federal Sustainability for the Next Decade Initial projects included: – High Efficiency Lighting Retrofit and some sensor installation – Water Conservation – Compressed Air System Repairs – Equipment Replacement 4 Typical Initial ESPC Projects

5. Energy Exchange : Federal Sustainability for the Next Decade Hill AFB ESPC T- 5 Lighting with sensors Site wide compressed air system upgrade with tie into central plant Ventilation improvements Waste water minimization 2,250 kW Renewable Landfill Gas to Energy Plant 210 kW ground-mounted PV array Other Facility & Energy System Improvements 5 Evolve to Comprehensive Energy Projects

6. Energy Exchange : Federal Sustainability for the Next Decade Utilizing ESPC for deep retrofit of over one million square feet of office space at the New Carrollton Federal Building and the Silver Spring Metro Center 1 building (SSMC 1) in Silver Spring, Maryland. Project highlights include: – Complete retrofit of mechanical systems/building controls – Energy consumption reductions of 60 percent against baseline usage – 50% water cost reduction against baseline usage – Major chiller plant upgrade and replacement with geothermal fied – 1 megawatt equivalent of on-site renewable energy, a geothermal well-field will operate below a parking lot covered by a large-scale solar canopy. – More than 11,000 new LED lighting fixtures will be controlled by a network of 2,000 occupancy and ambient light sensors 6 Evolve to Deep Energy Retrofit

7. Energy Exchange : Federal Sustainability for the Next Decade Fort Detrick - 18.6 MW solar project 25-year electricity purchase agreement with Fort Detrick and a 25-year land lease with the U.S. Army Corps of Engineers The facility is designed to be micro-grid compatible. All electricity from the solar facility will be consumed by Fort Detrick. Ameresco will build, own, operate and maintain the solar project. Ameresco is also building a 1.24 mile 4 kV distribution line to support the PV plant. The project is planned to be operational by February 2016. 7 ESCOs providing Supply-Side Only Projects
