Under this Programme, homeowners received grants of up to US$6,000, deducted from their loans, for incorporating energy efficient measures into their homes, such as east-west orientation, white roofs, radiant barrier insulation under roofs, tinted windows, shading, ceiling fans, energy efficient lighting, and solar or instantaneous hot water systems. Following the adoption of the programme by the Palau Housing Authority, every new housing loan in Palau is eligible for the grant. The programme was later revised to include existing houses and for loans for solar PV.
