Improving energy efficiency at the London Aquatics Centre

“Through analysis of the London Aquatics Centre existing energy performance we were able to identify opportunities for improved efficiency which have had a real impact on energy consumption at this iconic building. By working closely with our partners, we have helped to ensure the savings achieved by these measures are maintained through the life of the facility, ensuring a brighter future for the London Aquatics Centre.” – Stuart Denton-Brown, Energy Services Director-Commercial at ENGIE UK

The project brief:

ENGIE was already responsible for facilities management at the Queen Elizabeth Olympic Park when it was asked by London Legacy Development Corporation if it could assist with the organisation’s energy and sustainability goals for the Queen Elizabeth Olympic Park . The London Aquatics Centre, as the biggest energy consumer in the Queen Elizabeth Olympic Park , was identified as offering the greatest opportunity for energy saving improvements and sustainability initiatives, with reducing utility costs, energy consumption and carbon emissions, identified as the main goals for the project.

The solution:

In order to improve the energy efficiency and sustainability of the London Aquatics Centre, the project focused on making improvements in key areas, including venue heat and energy usage, reducing and re-using waste heat and building management. ENGIE’s online energy platform C3NTINEL was used to collect vital data from the Aquatics Centre such as energy consumption, temperature, pressures and valve positions, which allowed the ENGIE team to analyse and identify a number of energy reduction opportunities and building optimisation measures to implement.

A harmonious outcome:

A number of measures were identified and implemented at the London Aquatics Centre to reduce energy consumption, including pool pump optimisation, the installation of a jockey chiller, an upgrade of the air handling unit (AHU) controls and installation of destratification fans. This contributed to a 21% reduction in total heat consumed in the London Aquatics Centre between 2016-2017, and a 13% reduction in water consumption.
