Macerich is sharply focused on sustainability as a long-term, fully integrated business approach. Our goal is simple: Create a healthy environment for our employees, tenants, guests and communities and sustain this environment for future generations.

Today we are committed to doing even more — to reduce our greenhouse gas emissions, energy use, water consumption, and waste generation by 10 percent by 2020.  For more information click here.

What We’re Doing at Twenty Ninth Street

  • Twenty Ninth Street Management is proud to announce our partnership with the City of Boulder, Boulder County and Xcel Energy to launch a Tenant Sustainability Program designed to help advance more efficient, sustainable and cost-effective operations at the Center.
  • In 2014, the center installed 2,906 solar panels that will produce 727kw of power. That is enough energy saved to power 93 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 single stream recycling containers throughout the Center. The recycling program is available to Twenty Ninth Street guests and retailers.
  • 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.
  • Escalator start times have been set to coincide with mall operating hours to conserve energy usage.
  • We encourage recycling of environmentally hazardous materials, such as light bulbs, batteries and others.
