The hot gas that is produced as a by-product of creating cold air in the building will run through a heat exchanger to heat the water for the pool. It is also fitted with a full spectrum of lights which will give the building the appearance of a sparkling jewel-topped torch at night.
The pool is made from cast acrylic rather than glass, as this material transmits light at a similar wavelength to water so the pool will look perfectly clear.
