How Shopping Centers are Slashing Energy Costs with Sustainable Solutions

Fifteen years ago, commercial real estate developers began integrating solar energy and other eco-friendly features into their projects. Initially, retail developers doubted the feasibility of these green practices for retail centers, particularly regarding rooftop solar installations.

Walmart's Pioneering Effort

In 2007, Walmart challenged this skepticism by opening experimental big box stores in Aurora, Colorado, and McKinney, Texas, equipped with various energy-saving technologies, including rooftop solar. This move demonstrated the financial benefits of green building practices, shifting the perspective from environmental goodwill to profitable investment.

General Acceptance of Green Retail

Today, the retail industry widely acknowledges the advantages of energy-efficient measures. Enhanced energy performance and water conservation efforts, such as solar-powered pumps and high-efficiency irrigation systems, significantly reduce utility costs.

Adoption by Leading Retail Developers

Vestar, a major shopping center owner in the Southwest, embraced green initiatives early on. In 2007, Vestar launched its GreenSTAR sustainability program, leading to the development of the LEED-certified Oro Valley Marketplace in Tucson, Arizona. Currently, all Vestar properties participate in GreenSTAR, achieving up to 14% reduction in energy consumption.

Innovative Sustainability Measures

Vestar's sustainability efforts include using energy-efficient building materials, solar power, water harvesting systems, cool roofs, LED lighting, recycling facilities, drip landscaping, and EV charging stations. Additionally, Vestar collaborated with Arizona State University's Cool Pavement Project to mitigate the urban heat-island effect using innovative paving materials.

Energy-Saving Design and Technology

Anthony Brower from Gensler highlighted the use of durable stone materials with high thermal mass for passive heating and innovative building automation systems that reduce energy waste by adjusting heating and cooling based on door usage. These designs not only improve energy efficiency but also enhance the aesthetics and longevity of retail centers.

Sustainable Landscaping and Outdoor Innovations

Retail centers are also incorporating drought-tolerant plants, artificial turf, low-voltage illuminated signage, and hybrid light poles combining solar power with efficient lighting. These measures reflect a commitment to environmental stewardship, attracting eco-conscious consumers and supporting long-term sustainability goals.

Customer Comfort and Operational Efficiency

Energy-saving improvements, such as high SEER air conditioning systems and strategically placed misters, enhance customer comfort. Innovations in retail center designs, like storefront overhangs and extended building envelopes, improve both energy performance and the shopping experience.

Centennial's Comprehensive Sustainability Program

Centennial, a retail real estate investor, emphasizes sustainability in new construction and property upgrades through its SEE (Sustainability, Efficiency, and the Environment) program. The MainPlace Mall in Santa Ana, California, exemplifies this approach with numerous green initiatives, including ENERGY STAR-rated HVAC systems, advanced building management systems, and extensive recycling programs.

Significant Achievements and Future Goals

Centennial has made notable strides, such as reducing energy usage by 22%, saving $4.5 million in energy costs, and recycling substantial amounts of waste. Future goals include continuing to enhance the sustainability of their properties through innovative solutions and strategic partnerships.

The retail real estate sector has evolved significantly over the past fifteen years, embracing sustainable practices that not only benefit the environment but also improve financial performance. Early adopters like Walmart and Vestar have set a precedent, demonstrating that green building practices are both feasible and advantageous for retail centers.
