Sales for air conditioning are growing rapidly in buildings, more than tripling between 1990 and 2016. This energy use for air conditioning comes from a combination of rising temperatures, rising population and economic growth. Energy demand for climate control will triple by 2050, consuming more energy than the United States, the European Union and Japan today. This increase in energy will directly impact water consumption, either to cool a condenser of equipment directly or to serve indirectly as a basis for energy sources such as hydroelectric power that feed into these HVAC systems. Knowing the unique and growing importance of water, a new index, Total Water Impact (TWI) is presented, which allows a holistic comparison of the impact of water use on water, air and evaporative condensation climate systems.
