  1. 1. Save 25% Off Your Utility Bills EVEN IF YOU HAVE IMPLEMENTED CONSERVATION MEASURES PREVIOUSLY! MEC Ohio Energy Conference February 22nd, 2011 H. Kelly Tisdale C.E.M., LEED AP Energy Services Division Manager The Brewer-Garrett Company 1800-686-6869 ktisdale@brewer-garrett.com
  2. 2. Agenda The Need to be Green Measuring Current Consumption Benchmarking  Are you considered efficient or not when compared with similar Businesses Assessing Opportunities  Rebate Programs  Examine Cost and Savings for Energy Conservation Measures  Lighting, Ventilation, Automation, Boilers, Chillers Sanity Checks – Are savings projections realistic New Technologies
  3. 3. Greener than Green“The least expensive and most environmentally friendly unit of energy is the one that is never needed!” 100 Watt Light Bulb run year round
  4. 4. 100 Watt Light Bulb 1 MWhr 750 # of Coal 45,000 Cubic Feet (Balloons) of Carbon Dioxide
  5. 5. Greener than Green“The least expensive and most environmentally friendly unit of energy is the one that is never needed!” 100 Watt Light Bulb run year round This represents only about a 50th of what a US household consumes Today‟s technologies can reduce energy consumption up to 75%
  6. 6. Reduction in Pollutants forCuyahoga Community CollegeAnnual Reduction – 10,074,032 kWhGreenhouse Gases 10,600 TonsVOC 262 PoundsNOX 30 TonsCarbon Monoxide 2,100 PoundsSO2 44 TonsParticulates 2,500 PoundsMercury 270,000 Milligrams

  8. 8. Understanding Utility Bills - Gas Gas Utility - MCF of Gas 1200 1000 800 600 400 Heating 200 Cooking and Misc. 0 Hot Water July January August November June February May March April October December September Month
  9. 9. Measuring Current Consumption Convert everything to mmBtu… Gas – Total MCF  MCF = 1 mmBtu Electricity – Total kWh 1 kWh = 3412 Btu  Divide by 1,000,000 = mmBtu Example  1000 MCF = 1000 mmBtu  100,000 kWh = 341,200,000 Btu = 341.2 mmBtu
  10. 10. Benchmarking Know the total square footage for you facility – (example = 10,000 Utility = $225k mmBtu=1,341) Calculate mmBtu per square foot Example  Total mmBtu = 1,341  Total square footage = 10,000  Total mmBtu per square foot = .1341
  11. 11. BenchmarkingTypical mmBtu per square foot Schools .03 - .08 Universities .10 - .17 Commercial .12 - .15 Industrials .12 - .25 Use EERE at Rutgers Energy Star
  12. 12. Examining Energy ConservationOpportunities
  13. 13. Examining Energy ConservationOpportunities
  14. 14. Rebate Programs Lighting Prescriptive Method Will pay $7 per Lamp for t-12 or $1 per t-8 $50 per HID fixture Occ. Sensors, Exit Signs, Parking Lots, Exterior, Motors, VFDs, Vending, Cooling, PC Power Management, etc. Custom Program $.08 per kWh and $100 per kW Includes anything that reduces electrical load that is permanently installedProcess- application, Pre-retrofit survey, Post Application, and Proof
  15. 15. Examine Energy ConservationOpportunities Lighting  T-12 to T-8  T-8 to T-8  HID to T- 5  Assume cost at about $1.1 per square foot  Assume savings at $.17 per square foot  Example – 10,000 square foot facility  $11,000 cost  $1,700 annual savings
  16. 16. LED Benefits / Concerns Operational Savings  Reduced recycling costs, Extremely long life, Vibration and orientation proof. Energy and HVAC Savings – Up to 50% in some cases. Instant-on capabilities 0-100% dimmability Color changing Exceptional Lamp Lumen Depreciation No UV, No IR, No Mercury Small size allows for many new designs and ideas from the ground up that could not have been possible before. Drawbacks? COST! Glare issues if not properly applied or designed.
  17. 17. Established Types of LED Products General Illumination Replacements Incandescent Halogen Downlights Linear Landscape Architectural Signage Area
  18. 18. Technologies - OLED http://www.youtube.com/watch?v=f8S8tbQMp2k& feature=related
  19. 19. Examine Energy ConservationOpportunities Ventilation  Nearly 40% of your utility cost can come from conditioning outdoor air  ASHRAE requirements allow for different control  Potential Savings = .02 mmBtu per square foot  Typically 2 – 4 year payback
  20. 20. Examine Energy ConservationOpportunities Building Automation Savings of 2% to 3% off total Utility Retro-Commissioning also 2% to 3% Cost is Low  Payback typically < 1year to 3 years  Night set-back  Control Strategies
  21. 21. •The first HVAC controllers were pneumatic•The use of electromechanical relays in ladder logic, toswitch dampers became standardized.•The relays became electronic switches•By 1985, pneumatic control could no longer compete withthis new technology.•By the year 2000, computerized controllers were common•Today, some of these controllers can even be accessed byweb browsers and PDA’s?
  22. 22. Building Automation „Energy Harvesting Technology‟
  23. 23. Innovative BAS Solutions will.. Preserve existing investments in control and monitoring devices and integrate them with new standards-based technologies. Access and control through a standard web browser. Combine information from different systems to support better overall facility management. Increase flexibility of vendor selection Lower operational costs, improved facility operations, reduced energy costs, increased occupant/tenant satisfaction, and greater control, manageability, and security of building operations.
  24. 24. Examine Energy ConservationOpportunities Boilers (15 – 25 year ROI) Chillers (10 -20 year ROI) Occupancy Sensors (ventilation) Rooftops AHU‟s Processes Others  Water conservation  Air Dryers
  25. 25. Water Conservation New fixtures  Save nearly 40% of bill Cooling Towers  Deduct Meters Water Cooled Condensers  <1year to 3 year paybacks Irrigation  Deduct Meters Storm-water Management  Retention Ponds / Pervious Surfaces / Gardens
