Arguably one of the most straightforward areas where we can reduce energy use is to remove on site duplication of plant.
By this we are referring to the situation where valuable waste heat from a cooling system is rejected from a building but at the same time the building is using fossil fuels to provide space heating or hot water.
This situation can be found in any application from a manufacturing plant to a hotel/restaurant to a standard office building, all these buildings & their operational activity have a significant heating or hot water demand that can be operating alongside an equally significant rejected cooling load.
Basically high value waste heat is rejected from a cooling system within a building or process and at the same time a boiler could be operating in the same building; hence the production of energy is duplicated at very high cost.
Historically the specification of heating and hot water systems has been treated as a completely separate area to the specification of air-conditioning or refrigeration equipment.
