Energy costs (Ce)
Energy consumption is most often the largest component in the calculation of the life cycle cost for a pumping system. In commercial buildings, pumps often run more than 2000 hours a year.
Energy label
Most domestic appliances, light bulbs and cars offered for sale or rent in the EU must clearly display an EU Energy Label showing the product’s energy efficiency.
Energy meter

Enthalpy is a description for an amount of energy, and can be found in reference material for different elements at different temperatures and pressures. Enthalpy is often given as kJ/Kg.
Environmental costs (Cenv)
In the context of life cycle costs, environmental costs cover the cost of disposal of parts and contamination from the pumped liquid.
