Energy is the second highest cost for Leisure Centres after staff salaries. Energy can account for almost 30% of total running costs.


Introducing Leisure Energy


• New joint venture

• Driving up participation in sports and Leisure

• Driving down energy costs


Agenda


• Introducing Leisure Energy • Bridport Leisure Centre CO2 levels and costs – then and now • Understanding that leisure centre energy needs are distinct • Major areas of energy loss • Main energy lessons • Osprey Leisure Centre CO2 levels and costs – then and now • Monitoring • Improvements made at Bridport Leisure Centre • Leisure Centre A compared to Bridport Leisure Centre • Green Apple Energy Award • Future measures for Bridport and Osprey Leisure Centres


Bridport Leisure Centre – CO2 in tonnes


Emissions

2006 409.5 tonnes

2013 277.2 tonnes


Bridport Leisure Centre – Energy Costs



• Distinct energy footprint, different from the energy needs of a dry building


• Specialist understanding in this energy hungry sector

• Holistic approach to energy reductions

The Leisure Centre Swimming pool world


• How to control and reduce the energy needed for best operation


• What we have tested, developed and achieved within our network of Centres

• What systems we see coming in the future

The major energy areas for Pools




Pool (& Sports Hall) air handling – 24 hours x 365

Pool water pumping –

24 hours x 365

High bay lighting – 16 hours x 365

Heat losses from pool water




Free showers for any user

Complex site controls

Backwashing and dilution - high water costs

Energy broking, water negotiations

We establish, develop, test and monitor the best suppliers. Just as importantly, we avoid the poorer technologies.


• Get Energy efficient Equipment (difficult, but our specialism)


• Proper effective maintenance • Monitor energy, against a benchmark (Our

specialism)

Main energy lessons


• Don’t install new supply capacity (CHPs, Voltage Optimisers, Biomass boilers, Solar systems, heat pumps, etc) until you have first controlled your base energy use


• There is no point installing more supply, then continuing to waste it

Main energy lessons


• Then you can safely invest in renewables


• Avoid the rush to exciting new LEDs, Biomass and eco-bling. Find robust systems (our speciality)

Main energy lessons • Establish lean energy consumption first


Osprey Leisure Centre, Portland – CO2



Osprey Leisure Centre, Portland – Energy Costs




Bridport AHU Feb 2013 Tracking the Pool AHU dampers over 24 hours



Poor Dampers defeat even the best energy strategy



Bridport Boilers Feb 2013

Three different boiler temperature strategy – Condensing at 55 Deg., HWS at 72 Deg., and weekly purging at 90 Deg.



Bridport Lights and Cover



Bridport Lights



Poor main pool cover



Good pool covers, easy to deploy



Water Control 22 kW pool motor now running at 5kw - water quality excellent



Water Wasted costing £5,000p.a. in heated and treated water. We recycle it safely.

Receiving Green Apple energy award at Houses of Parliament


Bridport Leisure Centre – CO2 in tonnes


Emissions

2006 409.5 tonnes

2013 277.2 tonnes

The future – dual Solar & Heat pump project for this site. Very significant savings


Osprey Leisure Centre, Portland – CO2


The future – Air Source heat pump replacing gas for this site. Very significant savings.
