Designed to address residential needs in Hawaii's tropical climate, the University of Hawaii's semi-monocoque house, named Hale Pilihonua, is a sustainable and affordable solution for middle-income homebuyers.

The shell, or semi-monocoque, structure is:

  • Made of bio-based, fiber-reinforced polymer
  • Strong and lightweight
  • A tight, well-insulated thermal envelope
  • Resistant to damage from corrosion, termites, rot, and floods, which are common in tropical environments
  • Highly buoyant and able to float in the event of flooding
  • Insulated with Low-E glass to reduce heat loss at night.

The house's exterior structure consists of louvers that provide daytime shading, water-cooled photovoltaics that harvest energy, and solar thermal collectors for hot water. Additional sustainable innovations featured in Hale Pilihonua include phase-change material for thermal storage, intelligent occupancy sensing, and energy-conserving lighting controls and entertainment. The functional nature of Hale Pilihonua is demonstrated by an integrated aquaponics system that both enhances the atmosphere and supports sustainable food production.
