Top 10 Products That Save Money - Dan Ruben, Boston Green Tourism

  1. 1. How to Reduce Energy Use in New England’s Commercial Buildings June 15, 2010
  2. 2. Presenter <ul><li>Dan Ruben </li></ul><ul><li>Executive Director, Boston Green Tourism </li></ul>
  3. 3. Assess Your Building’s Energy Performance, 1 <ul><li>Benchmark your facility using measures like EPA Energy Star and against bldg energy checklists </li></ul><ul><li>Develop a tracking system for your energy use—what get’s measured gets done </li></ul><ul><li>Consider a professional audit and retro-commissioning </li></ul>
  4. 4. Assess Your Building’s Energy Performance, 2 <ul><li>Review the following aspects of your bldg’s energy performance: </li></ul><ul><ul><li>Operations and maintenance </li></ul></ul><ul><ul><li>Lighting </li></ul></ul><ul><ul><li>Plug load </li></ul></ul><ul><ul><li>HVAC system </li></ul></ul><ul><ul><li>Other energy-consuming systems </li></ul></ul>
  5. 5. Identify Financial Resources <ul><li>Find funding in your capital budget for energy efficiency projects </li></ul><ul><li>Identify tax breaks and utility rebates from your utilities http://dsireusa.org/ and your electric utilities. Incentives are rich in 2010! </li></ul><ul><li>Lump your capital expenses for energy efficiency into one project--pairing projects with lower and higher ROI’s into one package that meets your organization’s ROI target </li></ul>
  6. 6. Operations and Maintenance, 1 <ul><li>Some bldg managers reduce energy use by 10% with a rigorous maintenance schedule: </li></ul><ul><ul><li>clean coils </li></ul></ul><ul><ul><li>replace filters </li></ul></ul><ul><ul><li>calibrate controls </li></ul></ul><ul><ul><li>lubricate and adjust equipment </li></ul></ul><ul><ul><li>repair leaks in heating system ducts </li></ul></ul><ul><ul><li>optimize fresh air economizer operations </li></ul></ul><ul><ul><li>Replace worn weather stripping and seals </li></ul></ul><ul><li>Train bldg operators; consider Building Operators Certification Program (www.theboc.info/) </li></ul>
  7. 7. Operations and Maintenance, 2 <ul><li>Turn off when not needed: </li></ul><ul><ul><li>HVAC </li></ul></ul><ul><ul><li>lighting </li></ul></ul><ul><ul><li>electronics </li></ul></ul><ul><li>Best option for shutting down this equipment: up-to-date EMS’s with occupancy sensors; if not available, have staff do it </li></ul>
  8. 8. Operations and Maintenance, 3 <ul><li>Drapes/Blinds: strategically open or close them; keep closed during summer to eliminate heat gain; keep them open to gain heat in winter and provide free lighting </li></ul><ul><li>De-lamp </li></ul><ul><li>Set hot water at 120 degrees </li></ul>
  9. 9. Lighting <ul><li>Use natural light when possible. </li></ul><ul><li>Shut off unneeded lights with motion or occupancy sensors and timers; use photocells for exterior lighting </li></ul><ul><li>Replace standard incandescent bulbs with ENERGY STAR compact fluorescents (CFLs) </li></ul><ul><li>Replace T-12’s with T-8’s or T-5’s </li></ul><ul><li>LED’s will ↓ reduce energy, labor and a/c costs even more than fluorescents. Install LED’s for exit signs, down-lighting, hard-to-replace lights, etc. Be wary of lemons. Determine when , not if, your bldg will switch to LED’s. </li></ul>
  10. 10. Reduce Plug Load <ul><li>Use the most energy efficient equipment that suits your needs </li></ul><ul><li>At a minimum, select Energy Star equipment </li></ul>
  11. 11. HVAC Central Plant Systems, 1 <ul><li>Proper size is important </li></ul><ul><li>Energy-efficient boilers and chillers </li></ul><ul><li>Use free cooling when possible </li></ul><ul><li>Consider an energy recovery ventilation system </li></ul><ul><li>Energy Mgt. Systems: make sure they have good user interfaces, occupancy sensors, and scheduling and setback capabilities </li></ul>
  12. 12. HVAC Central Plant Systems, 2 <ul><li>Variable speed drives </li></ul><ul><li>Demand control ventilation </li></ul><ul><li>Recover waste heat: combined heat and power, laundry waste water, commercial refrigerators </li></ul><ul><li>Insulate ducts, pipes, etc. </li></ul><ul><li>Use ceiling fans to augment a/c </li></ul>
  13. 13. Building Shell <ul><li>Insulation and air sealing: particularly important for small bldgs </li></ul><ul><li>↓ solar gain with window tinting, awnings, solar shades, windows with low solar heat gain </li></ul>
  14. 14. Other Major Energy Consuming Systems, 1 <ul><li>Laundry: </li></ul><ul><ul><li>Ozone </li></ul></ul><ul><ul><li>Wash full loads only </li></ul></ul><ul><ul><li>Outsourcing may be more energy efficient </li></ul></ul><ul><li>Swimming pools and hot tubs: use covers </li></ul><ul><li>Vending machines: use misers </li></ul>
  15. 15. Other Major Energy Consuming Systems, 2 <ul><li>Kitchen: </li></ul><ul><ul><li>variable flow exhaust control on hoods </li></ul></ul><ul><ul><li>new dishwashers use < ½ the hot water of older units </li></ul></ul><ul><ul><li>replace refrigerators from before 1994 </li></ul></ul><ul><li>Computers: ↓ energy use by up to 50% by using Energy Star equipment, laptops, power mgt, web-based software, fewer servers, etc. </li></ul>
  16. 16. Consider Renewable Energy <ul><li>Solar thermal (hot water) and PV (electricity): more expensive than most efficiency measures; rich incentives often make them reasonable </li></ul><ul><li>Solar panels can be a marketing tool </li></ul><ul><li>Purchasing renewable electricity: usually more expensive; large buyers can often buy a portion of electricity at cost via reverse auctions </li></ul>
