The Water-Energy Nexus
It takes water to make energy and it takes energy to make water. In some buildings, the cost of water is significantly greater than the cost of HVAC+DHW energy, yet we don’t address it. Simple water retrofits can greatly increase the cash flow in a building. There are also many things that we use on a day to day basis that use immense amounts of water, and controlling this use reduces local and regional water consumption.
