  1. 1. Physical Activity and Leisure Management Ltd POOL PLANT OPERATIONS INFORMATION UPDATE SEMINAR (on-line option)
  2. 2. Physical Activity and Leisure Management Ltd MODULE 7: ENVIRONMENTAL MANAGEMENT
  3. 3. A major point for every pool, is the need to manage energy, and this module will introduce and explain just some of the innovative ways that huge amounts of natural energy sources (and money!) can be wasted or saved! 3 In this Module we will be focusing on:
  4. 4. 4 • How Big an Issue is Energy Management • Ventilation and Heating • Retrospective Energy Saving Opportunities • What are the Practical Options • Financial Impact • Biomass Boilers
  5. 5. How big an issue is Energy Management?  Every public building now has to display its DEC (Display Energy Certificate)  It indicates how energy efficient the building is.  There can be significant fines if buildings do not meet required standards 5

  7. 7. Ventilation and Heating  We draw in air from the external atmosphere, at anything between 0 C (or less), and 32 C.  We then heat it to approximately 31 C, in the pool hall.  The air in the pool hall becomes laden with damaging chemicals and therefore needs to be disposed of, at a rate of 8 – 10 air changes per hour. 7
  8. 8. Ventilation and Heating  We use fresh water constantly to replace losses in the pool, to replace after a backwash, etc.  The temperature of mains water can range from 14 C to 20 C.  We then heat it to approximately 29 C - 32 C.  A pool that measures 25m x 10m x 1m deep holds 250m³ of water (250,000 litres).  In addition, there is also the water that is in the circulating system. 8
  9. 9. 9 Retrospective Energy Saving Opportunities • “A” rated plant – Condensing Boilers • Invertors • Pump Controls • CHP – Combined heat and Power • Heat recovery Technology • Control Upgrades • Renewable energy/Bio-mass boilers • Pool Covers & Operating procedures How do you know where to start?

  11. 11. Ventilation and Heating  Simply by recirculating the latent heat from the outgoing air, and using it to warm the incoming air can have a massive effect on our Carbon emissions, as well as our Financial positions.  Large quantities of water evaporate from the pool surface, from wet surrounds and from occupants. If this vapour is not removed either by dehumidification or by ventilation the relative humidity will become unacceptably high, resulting in damage to the building structure in places where condensation cold spots occur. 11
  12. 12. what are the options, in real and practical terms?  Investment in energy saving technology and equipment is the best alternative, but the initial funding may be an issue. Funding solutions are available, though.  Monitoring and Maintenance of existing equipment and systems is an area that can also produce substantial improvements. 12
  13. 13. What can the financial impact be?  There has to be a cost of installation; an investment.  Savings can begin immediately.  It is the ‘payback period’ which is important, because once the cost of installation has been recouped, the continuing savings are against your budget. 13
  14. 14. Bio-Mass Boliers  Bio-Mass or Wood-burning, boilers, use timber from sustainable tree planting.  The timber pellets are dried, and fed through a hopper. Obviously there is a major reduction in the use of oil or gas. 14
  15. 15. Geothermal Heat Sources There are several methods of extracting heat from below the earth’s surface. Perhaps the most straightforward system is to pump cold water several hundred meters below the surface where it is heated to very high temperatures. This hot water is then retrieved by pumping it towards the surface. Much shallower systems can also be used, such as ‘ground source heat pumps’. 15
