Type of Project: Building Certification
Services Provided: Full LED lighting retrofit and Photovoltaic System consulting

With the guidance of Green Building Hawaii, the Hyatt Regency Maui Resort and Spa has become the first resort in Hawaii, and the third resort in the world, to achieve a Silver level certification under the United States Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) for Existing Buildings Operations and Maintenance (EBOM) rating system. This significant achievement recognizes the Hyatt’s outstanding performance in areas such as energy and water efficiency, waste diversion and recycling, sustainable purchasing, site management, and indoor environmental quality.

“The successful bid for a LEED certification by the Hyatt could not have been achieved without the support of the entire organization. Green Building Hawaii is proud to have played a key role in their certification process and be a part of this outstanding team” said Alex de Roode, Director of Sustainability & Business Development for Green Building Hawaii.

The property recently completed renovations throughout the resort, including the pool area, Drums of the Pacific Luau, and dining outlets.

Among the sustainable features of the property are:

  • Six million gallons of water saved annually, through new reduced flow shower heads in all guest rooms
  • Complimentary digital newspapers made available for guests through most mobile devices and computers
  • Motion-sensing air conditioning that turns off when lanai doors are open, or when guests leave the room
  • Recycling receptacles in every guest room
  • Non-turf landscaping which is 100% native and the addition of adaptive plants
  • Installation of an intelligent, weather-based, real-time irrigation system combined with grey water irrigation have reduced landscape water use by over 27%
  • More than 70% of purchased items are local, recycled or made with a renewable resource
  • Over half a million pounds of leftover and scrap food donated to local pig farms for feed and compost
  • Digital signage has replaced printed signage

The LEED EBOM rating system is administered by the U.S. Green Building Council. To qualify, buildings have to show a significant increase in diverting waste from landfills and an increase in energy and water efficiency, as well as a robust sustainable purchasing program. Hyatt Regency Maui applied for, and received the certification based on how well the resort measured against LEED standards. Additionally, as a result of the resort’s adherence to high environmental standards previous to its LEED EBOM certification, Hyatt Regency Maui has been recognized for its green efforts from numerous other environmental organizations including: the TripAdvisor GreenLeaders™ Silver ranking; a 2010 Green Key four-key distinction, representing outstanding industry leadership and a commitment to protecting the environment; a Hawaii Green Business membership designation in 2009, recognizing the resort’s efforts to operate in an environmentally responsible fashion; and induction into the Energy and Efficiency Hall of Fame by Maui Electric Co. in 2007.



In 2018, Hyatt San Francisco Airport participated in LEED® Performance Score, which is a USGBC® program that awards points based on efficiency of operations and occupant well-being. Performance was assessed across five sustainability categories including Energy, Water, Waste, Transportation, and Human Experience. The LEED® plaque shows the total performance points for each sustainability category.

Green Building Hawaii and their partner Unico Sustainability provided LEED consulting services to guide Hyatt SFO though the LEED Performance score process. The successful LEED Gold certification made Hyatt SFO one of the first large hotel properties in the country to use the Performance Score for it’s initial certification. The program will ensure continued involvement and improvement as performance metrics are continually updated as part of the process.
