This document provides information about an online seminar on environmental management for pool plant operations. The seminar module focuses on energy management, ventilation, heating systems, and options for retrofitting existing facilities to save energy and costs. Specific topics covered include displaying energy usage certificates, typical energy consumption breakdown in leisure centers, targeting changing areas and pools for improvements, heat recovery technology, biomass boilers, and geothermal heat sources. Retrofitting ventilation systems and installing more efficient equipment such as condensing boilers and heat pumps can significantly reduce carbon emissions and operating costs over the long term once installation costs are recouped.

MODULE 7:
ENVIRONMENTAL MANAGEMENT

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!

In this Module we will be focusing on:

• How Big an Issue is Energy
Management
• Ventilation and Heating
• Retrospective Energy Saving
Opportunities
• What are the Practical Options
• Financial Impact
• Biomass Boilers

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

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.

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.

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. 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.

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. 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.

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.

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’.
