ORNL ESPC Overview GovEnergy 2008

ESPC Project Summary  $89M project funded by $8.2M in guaranteed annual savings  Energy Conservation Measures: 1.Select Steam Decentralization of Remote Buildings 2.Super Boiler technology 3.Building Management System 4.Advanced Electric Metering 5.Comprehensive HVAC Upgrades 6.Energy Efficient Lighting 7.Water Conservation Measures 8.Compressed Air Cooling  Reduces fossil fuel consumption by over 80%! Emissions reduction equal to: removing 2.1 million cars from the road annually or planting 32 million trees!

ESPC Project Summary (continued)  Addresses 6 of the Secretary’s TEAM goals  Reduces energy intensity in lab / office buildings by 30% Meets long-term energy reduction goal of 30%  Reduces water usage by over 115M gallons/year Meets long-term water reduction goal of 16%  Aligns with ORNL Ten Year Site Plan

Meeting the Primary TEAM Initiative Goals

Renewal Energy Showcase: Biomass Gasification System Scope Upgrades existing natural gas steam plant to a wood gasification biomass plant Biomass plant integrated with existing plant for one integrated facility Upgrades outdated infrastructure in existing plant Upgrades existing steam distribution system Woody biomass will be sourced within a 50 mile radius Benefits Reduces fossil fuel consumption by over 80%! Major renewable energy utilization Integrated with ORNL Biomass and Syngas research initiatives

Energy Conservation Showcase: EERE’s Super Boiler Technology Scope Elimination of over 1.5 miles of steam piping to Melton Valley Johnson Controls and ORNL worked together to incorporate EERE’s Super Boiler Technology in the new Melton Valley Steam Plant Benefits Super Boiler operates at up to 94% efficiency NOx and CO emissions < 5ppm, extremely “clean” Integrated M&V approach provides on-going research information

Other Energy Conservation Measures ECM 3.1 Building Management System Upgrades ECM 3.2 Advanced Metering and Energy Awareness “Smart Meters” will integrate with ORNL’s energy management system Incorporates lab-wide program for energy awareness and sustainability education ECM 4.1 Building Mechanical Upgrades ECM 5.1 Lighting Utilizes DOE scotopic and photopic research where applicable ECM 13.1 Water Conservation Reduces domestic water consumption by over 50% ECM 13.2 Compressed Air Cooling System Eliminates over 100 million gallons annually of once-through cooling water Reduces site water consumption by 14% It takes the entire “bundle” to meet the TEAM Initiative!
