A lot of ground breaking work has gone into the London Aquatics Centre to make sure the building uses the least amount of water and energy as possible.
Our energy work includes:
Turning down all pool pumps
The training and competition pool pumps have now been turned down to 85% of their power during the day, and 70% during the night, and the diving pool maintaining at 70% 24/7 in line with its use. This still keeps the pools crystal-clear, whilst saving £35,000 of energy a year.
Upgrading the heating and cooling systems
The air conditioning in the building has been upgraded with new controls. This allows cooling using outside air when cold enough instead of using energy to cool it down, and ensures heating is only used when necessary.
Recycling hot air
The main competition pool hall is now kept at 27oC using “destratification fans”. These fans blow the rising warm air back down to pool level, protecting expensive equipment in the roof whilst making sure swimmers are the perfect temperature whilst at pool side.
District energy network heat reduction
The building is connected to the Park’s district energy network, and has significantly reduced the amount of heat it needs. This helps the whole network run more efficiently, and the wider Park more energy efficient.
New innovations for energy efficiency
Our newest innovation will be a variable flow rate chiller, which will use less energy to cool the building down, whilst enabling heat generated through the chilling process to heat the 50m training pool.
We’re making sure the London Aquatics Centre’s 10 million litres of water is reused as much as possible by:
Reusing pool water for toilets
Our backwash recovery system collects water used in the pool, using it to flush all the toilets in the building. This saves nearly two Olympic swimming pools worth of water every year.
A new reverse osmosis system will allow us to recycle most of the pools' water, whilst keeping it clean. This means less new water will need to be introduced into the pools.
This work has resulted in 601 tonnes of CO2 being saved since 2014 – which continues to reduce – equivalent to a 61% reduction in operational emissions intensity. In addition, the London Aquatics Centre has achieved an 18% reduction in water consumption against the 2014 baseline.
