Sustainability Report

The redevelopment prioritized lowering material-related emissions through:

• Replacement of traditional pili grass roofing with synthetic thatch made from recycled plastic, which:

  • Reduces harvesting pressure on native ecosystems

  • Diverts plastic waste from landfill streams

  • Extends lifecycle durability, lowering replacement frequency

• Extensive reuse and salvage strategy following tsunami damage:

  • Original structures were carefully deconstructed

  • Usable materials were repurposed in local community projects

  • Reduced demand for newly manufactured materials

• Use of vernacular lightweight construction typologies:

  • Reduced structural mass and concrete consumption

  • Improved constructability and reduced transport emissions

• Local sourcing of materials where feasible to minimize transportation footprint.

The resort operates a microgrid system providing nearly full operational energy supply:

• Over 8,000 photovoltaic panels

• Solar generation capacity: 2.3–2.5 MW peak production

• Energy storage: Four large-scale battery systems enabling load balancing and grid independence

This significantly reduces operational carbon intensity compared to fossil-fuel-powered resort infrastructure. Operational energy demand is further reduced through:

• Building orientation for prevailing winds

• Cross-ventilation strategies reducing reliance on mechanical cooling

• Deep roof overhangs and shaded walkways minimize solar heat gain

• High-performance glazing reduces cooling loads

• Car-free internal circulation promoting walking and cycling

• Passive survivability enabling continued habitability during power outages

• Integrated water management

• Stormwater capture systems

• Wastewater treatment and reuse

• Irrigation using well water and lagoon water

• Reduced potable water demand and associated treatment energy

The project reduces long-term service emissions through:

• Durable synthetic roofing requiring less frequent replacement

• Passive cooling lowering mechanical equipment wear and maintenance loads

• Distributed low-rise building typology simplifying repair and replacement

• On-site renewable energy infrastructure reducing reliance on carbon-intensive energy services

• Integrated water recycling reducing external infrastructure dependence
