Methodist Ladies College Aquatic Precinct
An innovative hybrid geothermal heating system was designed so that it now serves both pools. The exceptional approach to energy efficiency has resulted in the most operationally efficient, heated aquatic precinct in Australia.
The Methodist Ladies College (MLC) Aquatic Precinct involved the replacement of an existing pool with a new 16 lane, outdoor heated (geothermal), lap pool. This new swimming pool was designed to accommodate competitive water polo and advance facilities for both Methodist Ladies College and its neighboring institution, Christchurch. By merging the two aquatic precincts, the project optimizes resource utilization, improves operation costs, and elevates the facilities available to students from both schools.
A hybrid geothermal heating system was designed using latent energy from the existing CCGS geothermal water system, so that it now serves both pools with only a small 20% increase in energy draw. High delta-T, low approach heat exchangers were selected for increased heat extraction, and smart algorithms for the control systems. These combined initiatives have resulted in a halving of net unit energy reduction of 60% across the precinct, to produce the most efficient heated aquatics installation in Australia.
Lap Training and Competitive Water Polo
The design of the aquatic precinct includes a 40 x 25-meter heated pool that serves as a lap training facility and meets FINA standards for water polo. This dual-purpose pool caters to the diverse needs of aquatic activities, supporting the development of competitive water polo teams and providing an optimal space for lap training.
Innovative Balance Tank Design
A balance tank design was incorporated around the pool structure, serving a dual purpose of thermal energy storage and rainwater storage. This design significantly contributes to reduced peak heating and electrical loads, minimized water consumption, stabilized water chemistry, and an overall reduction in operational costs for the school.
Efficient Control Systems
The project employed smart algorithms for the control systems, leveraging time-of-day electricity rates and thermal capacity. High delta-T, low approach heat exchangers were strategically selected to enhance heat extraction, ensuring optimal energy utilization during different times of the day.
The collective initiatives undertaken in the Methodist Ladies College Aquatic Precinct project have resulted in a remarkable achievement—an impressive 60% reduction in net unit energy consumption across the entire precinct. This positions the pool as the most efficient heated facility in Australia.
