Ways to Save Energy by Saving Water

May 27, 2014 | 2 comments

Did you know that water and energy usage in commercial buildings go hand in hand? It may not seem obvious, but you actually can save money on your energy bills by reducing how much municipally supplied water your commercial building uses.

The less hot water being used for showerheads, faucets, appliances, and equipment, the less energy your commercial building will need to use in order to heat the water for use (if electricity or gas is how you heat your water).

Another interesting fact: Because your local utility uses energy to purify and pump municipal water to your facility – and to treat sewage – a portion of your water/sewage bill could be considered an energy bill. According to the U.S. Environmental Protection Agency’s WaterSense program, on average, the energy used to deliver and treat water for 10 households each year could power a refrigerator for more than two years.

Here are some water-saving tips that will also help to reduce energy usage in your facility:

  1. Run commercial washing machine loads with cold water when appropriate
  2. Encourage tenants/occupants to take shorter showers
  3. Invest in low-flow faucets and showerheads, and install WaterSense fixtures where suitable. These fixtures are independently certified to be at least 20% more efficient than standard fixtures.
  4. Incorporate xeriscape landscaping to reduce irrigation requirements. If irrigation is still a necessity, there are WaterSense irrigation controllers that can prevent overwatering and reduce water loss due to evaporation, wind, or runoff.
  5. Continue to implement energy-efficiency measures that reduce HVAC usage, such as installing window film and optimizing equipment start-up/shutdown time. Reducing the need for heating and cooling will reduce the amount of water required by these systems.
  6. Consider rainwater harvesting. Captured rainwater can be used for irrigation, as well as in cooling towers, boilers, and evaporative coolers.
  7. Invest in ENERGY STAR-rated commercial kitchen appliances, such as ice machines, pre-rinse sprays, dishwashers, and steam cookers.

Have you made adjustments to water usage in order to save energy? How have those initiatives worked for your building?

    Thank you for connecting water with energy

    I oversee and conduct a seminar called:
    Water Consciousness — The Physics and Geometery of Water,

    This establishes the context as why I need to be Water Consciousness.

    Once that is done the details or the content as to why to save water becomes a constant. It eventually leads to becoming extremely energy effecient.

    Thank you once more.
