Banner Estrella Medical Center and Salt River Project (SRP) are teaming up to save money, conserve energy and promote sustainability. Banner was the first recipient of the SRP PowerWise Retrocommissioning Solutions Program.

Instead of purchasing new equipment, Banner has received a tune-up on its existing systems, includes heating, ventilation, air conditioning, central plants, lighting systems and (HVAC) components. It expects a payback in less than six months, estimating energy savings of more than $100,000 in the first year.

So far, Banner has lowered its natural gas usage and improved its water consumption in the cooling tower due to the tune-up it received.

Being able to save money and energy is a big step for companies in this economic day and age. Some smaller companies are not able to purchase new equipment to be “green” or sustainable; Banner has opened the door for them. Retrocommissioning is an option being provided by SRP to use what you have to gain what you need.

The not-for-profit medical center opened six years ago and has been consistently looking for ways to reduce cost, reduce waste streams and energy. In 2009, Banner saved nearly $1 million by installing reverse osmosis water systems and eliminating bottled water, according to its website.

Salt River Project is the third-largest public power utility in the country and serves more than 945,000 electric customers. It is the largest supplier of water in the Phoenix, providing resources for consumers and businesses.

Working together, the two companies are a guiding force for sustainability.
