  • In 2014, the center installed 5,081 solar panels that will produce 601,267 kWh of power. That is enough energy saved to power 83 homes' electrical use for one year!
  • We use green cleaning products at our center wherever and whenever possible.
  • The center has implemented new lighting protocols that allow us to minimize our energy use and lower our carbon footprint without any impact on the shopping experience.
  • Our center has a recently upgraded HVAC system that minimizes our energy usage and lowers our carbon footprint.

  • We have waterless urinals in the men’s restroom. Additional water reduction in the restrooms is achieved with automatic flush and automatic faucets.
  • Motion sensor lights are installed throughout the Center to conserve energy usage.
  • Xeroscaping was used in the landscape design to conserve water consumption while maintaining a beautiful shopping environment.
