Presentation Transcript

  1. Water & Energy Efficiency In Recreation Facilities

  2. Presentation Overview • Solar PV, Solar passive, Geothermal • Variable speed drives (VSD) • Lighting and switching • Voltage reduction • Leaks • Fixtures and fittings • Irrigation • Pool back wash

  3. Collect BAU Data • How much energy does it currently use? • What claims to the supplier make? • Do they seem feasible? • Check usage after installation

  4. Solar PV • Good payback • Check interval data • Structural engineering reports • Panels ain’t panels • Renting roof space (ownership and title issues)

  5. Passive Solar • Vacuum tubes. Heat pump hot water systems

  6. Geothermal

  7. Variable Speed Drives • Pool pumps • Air handling units

  8. Lighting

  9. Lighting • Reduce power costs • Reduce maintenance and replacement costs • Reduce OHS risks • Check supplier carries spares and warranty coverage

  10. Light Switching • Swipe card • SMS • PIN • Charge by the pole (Single and multiple lamp poles, varying lamp wattages, pole and lamp maintenance)

  11. Voltage Reduction • New transformer (Dynamic or static) • TX over ride • Site survey • Resistive loads • Inductive loads

  12. Small Appliances • Star rating • Purchasing policy • Whole of life cost (Purchase, operation, maintenance)

  13. Water • Leaks • Fixtures and fittings • Irrigation • Pool back wash

  14. “Patron Dependent” Vs “Patron Independent” Water Use • Dependent – ablutions etc. • Independent – Evaporation, irrigation, (to some extent) backwash

  15. Implications For Water Efficiency • Patron dependent water use = lower capital costs and maintenance • Showers • Taps • Toilets & urinals • Leaks within these

  16. Implications For Water Efficiency Patron independent water use = capital expenditure, BUT is often a “one off” cost • Pool covers and shade structures • New filters • Irrigation upgrades may need complete systems replacement • Sub meters

  17. City/Country Comparison (Potable only)

  18. Leaks

  19. Covered By Standards

  20. Covered By Standards

  21. Not All Labels Are Standards

  22. Irrigation Some systems using wrong sprinklers (even though they appear to be working)

  23. Irrigation Systems with even head spacing

  24. Irrigation System Design • May be suited to pro forma system design

  25. Sub-meters • Water Management • Leak Detection • Quantification (i.e. irrigation systems, backwash events, ablution water use per patron)

  26. Sub-meters Meter: • Main irrigation solenoid • Single point large loads (Make up water, ablutions where possible)

  27. Sub-meters • Pulse capable • Pulse rates of =>1 pulse per 10 Litres • Can be fitted with loggers • Read in conjunction with main meter

  28. Data Loggers

  29. Data Loggers

  30. Data Loggers

  31. Sub-meters & Data Loggers • MUST be read • MUST be analysed • MUST be acted on • Make it someone’s job

  32. Thank You
