Same Jetc May 6 2010

  1. 1. 2010 Joint Engineer Training Conference & Expo Society of American Military Engineers Presented by: George Plattenburg, PE Sr. Vice President, Sales & Marketing May 6, 2010 Georgia World Congress Center Atlanta, Georgia
  2. 2. Agenda <ul><li>About Servidyne </li></ul><ul><li>Generating Energy Cost Savings through Operations & Maintenance </li></ul><ul><li>Retro-Commissioning </li></ul><ul><li>Continuous Commissioning </li></ul><ul><li>Demand Response </li></ul><ul><li>Off-Hours Investigation </li></ul>
  3. 3. Servidyne – Company Profile <ul><li>Founded in 1925 with 30+ years experience in energy efficiency & optimizing building performance </li></ul><ul><li>Headquartered in Atlanta, offices across the U.S. </li></ul><ul><li>SERV NASDAQ </li></ul><ul><li>Eight time United States EPA ENERGY STAR ® Partner of the Year </li></ul><ul><li>Recognized for Presidential Award for achievements in outstanding energy management (BLM) </li></ul>
  4. 4. Existing Building Focus and Expertise <ul><li>Our business is predicated on assisting owners and operators of existing buildings and bases </li></ul><ul><li>Servidyne has implemented a number of energy programs and projects at local, state, and federal facilities and all branches of the military </li></ul><ul><li>We don’t sell or service products; we provide comprehensive solutions </li></ul><ul><li>Capable of working with all of the major types of building automation systems, metering technologies, and controls </li></ul>
  5. 5. Generating Energy Savings with O&M <ul><li>The best approach to reduce energy consumption in most cases is through optimized O&M </li></ul><ul><li>Consider CapEx improvements after your energy consumption requirements with your existing systems have been minimized </li></ul><ul><li>Buildings and systems need to be fine-tuned or “retro-commissioned” </li></ul><ul><li>Many improvements can be made with little or no cost and covered by O&M budgets – savings range from 5-15% </li></ul><ul><li>Costs for this approach range from $0.10 to $0.20/sq. ft. or less; paybacks can be in months and not years </li></ul><ul><li>Process includes training of site staff </li></ul>
  6. 6. Retro-Commissioning <ul><li>Why Retro-Commissioning? </li></ul><ul><li>Buildings never commissioned properly </li></ul><ul><li>Over time set points and systems have been altered, bypassed, and replaced. </li></ul><ul><li>Owner’s operating requirements have changed </li></ul><ul><ul><li>Occupancy </li></ul></ul><ul><ul><li>Addition/subtraction of spaces </li></ul></ul><ul><ul><li>Different space types </li></ul></ul><ul><li>Design standards have changed </li></ul>
  7. 7. Retro-Commissioning Top 10 <ul><li>Schedule HVAC Systems </li></ul><ul><li>Adjust Outside Air to Current Needs </li></ul><ul><li>Mitigate Simultaneous Heating and Cooling </li></ul><ul><li>Reduce Flow from Oversized Pumps </li></ul><ul><li>Reset Supply Air Temperatures </li></ul><ul><li>Enable Economizer Controls </li></ul><ul><li>Reset Static Pressures/Optimize VFD Operation </li></ul><ul><li>Stage Boilers/Chillers Properly </li></ul><ul><li>Lower Condenser Water Setpoints </li></ul><ul><li>Correct Lighting Control Operation </li></ul>
  8. 8. Retro-Commissioning Process Review Project Objectives Develop RCx Plan Conduct Scope Meeting with Customer Perform Site Assessment / Complete Simple Repairs Prepare List of Deficiencies & Potential Improvements Develop Diagnostic Monitoring & Functional Testing Plans Perform EMS Trending and/or Data Logging Perform Functional Testing (as required) Add Improvements and/or Deficiencies to the Master List Prioritize & Select Cost Effective Opportunities for Improvement Implement Repairs and Improvements Verify Corrected System Operation Correct Deficiencies No Yes Prepare & Submit Final Report Results Achieved? Verify Performance & Track Expected Results vs. Actual Results Planning Phase Assessment Phase Implementation Phase Reporting and M&V Phase
  9. 9. Persistence of Savings <ul><li>What Is Continuous Commissioning? </li></ul><ul><li>Inexpensive but reliable sensor and system monitoring technology </li></ul><ul><li>Integrate with existing building systems and ‘smart grid” metering technologies – utility consumption, building & system conditions </li></ul><ul><li>Customized robust information dashboard capturing data to provide ongoing monitoring, alarming, and energy consumption trending </li></ul><ul><li>Can identify system faults and maintenance issues prior to equipment failure </li></ul><ul><li>This “Continuous Commissioning” process will ensure the savings realized through Retro-Commissioning will continue into the future. </li></ul>
  10. 10. Continous Commissioning Monitoring-based Continuous Commissioning
  11. 11. Demand Response <ul><li>Many utilities (and ISOs) across the U.S. are offering “Demand Response” or load curtailment programs </li></ul><ul><li>The utilities have a reliability/economic challenge meeting peak demand for a limited number of hours every year – typically weekday afternoons in the summer </li></ul><ul><li>To encourage customers to become “part of the solution” utilities will pay you to reduce demand when called </li></ul><ul><li>Payments range from $30/kW to $80/kW across the country </li></ul><ul><li>Requirements on notification and load shed periods vary </li></ul>
  12. 12. Demand Response <ul><li>You can participate in demand response through O&M </li></ul><ul><ul><li>Adjust chiller and space set points </li></ul></ul><ul><ul><li>Dim lights </li></ul></ul><ul><ul><li>Turn off unnecessary loads </li></ul></ul><ul><ul><li>Throttle back VFDs on pumps and fans </li></ul></ul><ul><ul><li>Engage back-up generators </li></ul></ul><ul><li>Requires a demand response audit to identify measures </li></ul><ul><li>Typically requires live testing prior to enrollment </li></ul><ul><li>Payments are based on performance and/or testing </li></ul>
  13. 13. Off - Hours Investigation <ul><li>Walk your buildings during unoccupied periods </li></ul><ul><li>Listen for air and water movement </li></ul><ul><li>Look for lights that are on </li></ul><ul><li>Observe HVAC control set points and actual space conditions </li></ul><ul><li>Significant amounts of energy are wasted during “sleeping hours” for your buildings </li></ul><ul><li>Encourage active participation in energy management </li></ul><ul><li>May be lowest hanging fruit of all </li></ul>
