To improve energy efficiency in our culinary operations, we’ve implemented a Melink demand-based ventilation system in the main kitchen. This smart technology adjusts exhaust and air fan speeds according to real-time cooking activity, using temperature sensors and a microprocessor-controlled variable speed drive. By reducing fan usage during periods of low or no activity, the system significantly lowers energy consumption—delivering estimated annual savings of 26,336 kWh and lifetime savings of 395,041 kWh.

Royal Lahaina Resort & Bungalows is proud to lead with sustainability through a multi-phase photovoltaic solar initiative completed in 2020 and 2022.

In Phase One, 628 rooftop solar panels were installed across the resort’s existing structures, generating 226 kWh of clean energy. Phase Two expanded the project with a cantilevered solar carport system, adding 1,492 additional panels and generating 656 kWh. Together, the two phases comprise a total of 2,120 solar modules with a cumulative capacity of 882 kW DC—producing an estimated 1.4 million kWh annually.

The project was supported by federal and Hawai‘i state tax incentives and achieved a projected return on investment in just 2.6 years. According to the U.S. EPA greenhouse gas equivalency calculator, this initiative helps offset approximately 977,000 kilograms of CO₂ emissions each year—the environmental equivalent of planting over 16,500 trees.

This solar project is a key component of Royal Lahaina’s broader commitment to sustainability and environmental stewardship in the islands.

Royal Lahaina Resort & Bungalows is advancing its commitment to sustainability by participating in the Maui Nui Marine Resource Council’s Reef Friendly Organic Landscape Certification program, aiming for Gold Level status. Efforts include planting native Hawaiian trees featured in the resort’s complimentary cultural tour, adding native plants to luau grounds to conserve water, and launching on-site composting to eliminate fertilizer use and reduce waste. These initiatives foster a deeper sense of place while supporting Maui’s natural ecosystem.

Royal Lahaina Resort & Bungalows has implemented a recycling program that includes cardboard, glass and metals for a waste diversion rate of 29.6%. Smart thermostats have been installed in 395 guest units, resulting in peak electric demand reduction of 145.36 kWh, annual energy savings of 479,569 kWh and lifetime energy savings of 7,193,542 kWh. This energy management system uses an occupancy sensor to detect when a hotel room is occupied or unoccupied adjusts the temperature to a higher HVAC setpoint during periods of no occupancy. Entry doors and lanai doors have door switches that will de-energize the AC when the doors remain open.

Royal Lahaina Resort & Bungalows is proud to hold a 4 Green Keys rating from Green Key Global—recognizing our leadership in environmental stewardship. This distinction honors our comprehensive sustainability efforts, including established programs that engage our team, guests, and community, delivering measurable and lasting results.
