How is Energy Consumed
The image below demonstrates where energy is used in a swimming pool hall. We introduce some possibilities for making improvements below that...

- Fabric losses are caused by the design and condition of the building itself. The more insulation in the ceiling and walls, the less heat that will be lost due to conduction.
- Pool water may lose a little heat through conduction to its surroundings, and more to hygiene procedures such as backwashing etc. Probably the greatest cause of heat loss from the pool water is down to evaporation. Every litre that evaporates from the surface of the pool takes 0.75kW of heat with it.
- Ventilation losses are associated with the energy that it takes to heat the air in the pool hall from ambient condition to 30oC in a well operated swimming pool. Considering the vast size of most pool halls and air change rates up to 10 times an hour, this can make up a substantial element of the pools energy consumption, particularly in the winter when it can be extremely cold outside.
- Fans and Pumps are required to move air around the building and to pump water through the pool and the filtration systems. These can be sizable pieces of equipment.
