Ala Moana Sustainability Initiatives


Boasting more than 2.3 million square feet of GLA, Ala Moana Center in Honolulu, Hawaii, is the largest outdoor shopping mall in the world. In 2015, GGP unveiled plans to dramatically expand the center using a wide range of environmentally friendly materials and a construction waste management team that diverted 75% of all metals, wood, concrete, asphalt and masonry from the waste stream.

The Ewa Expansion represented the first phase of the project, which began with the removal of a former Sears department store and the addition of a 186,000 square-foot Nordstrom featuring two levels of shopping space. Ala Moana Center also acquired a 165,000 square-foot Bloomingdale’s and more than 240,000 square feet of luxury retail and big box store space. This new construction featured sustainable architectural elements that lessen the reliance on HVAC systems, including a white roof membrane designed to reduce heating and cooling costs.

Energy-efficient LED lighting was installed and incorporated into Ala Moana Center’s Energy Management System and G2, which are EOA building management platforms that optimize control and efficiency. The expansion area was equipped with state-of-the-art cooling towers to harness a cost-effective method of cooling each tenant’s space. In addition, other adjustments were made including the installation of ultra-low flow plumbing fixtures and smart irrigation controllers to minimize water usage throughout the entire center.

Coconut trees and other native vegetation were planted throughout the expansion area and enhanced with shade structures to cool the concourse without impeding air flow. Paving materials in a light-colored stone were used to reduce the heat island effect and create a more comfortable experience for tenants and visitors alike.

To reduce traffic congestion and provide tourists easy access to the center, several stops were added at the Ewa Expansion to connect Ala Moana Center’s trolley system with local hotels, thus effectively reducing GHG emissions. In addition, convenient EV charging stations were added to encourage customers to recharge their vehicles while shopping or dining.
