Inspired by the bahay kubo, the Philippine Embassy and Chancery in Brunei embodies the rich culture of the Philippines and fuses vernacular and international styles and facets of Asian architecture. Completed in 2009, its design applies green design principles like installing a green roof instead of ordinary roof slabs to dissipate heat. Green walls were added along the three courtyards and the social hall and athletics court on the northwest. The location of the courtyard allows passive cooling.

In addition, the structures are oriented along the east-west solar axis to minimize undesirable direct sunlight, while areas exposed to intense sunlight are provided with sun buffers. The buildings are also designed to have multilevel floor elevations following the site’s rolling terrain to minimize alterations to the natural topography. The rooms were also arranged so that each is naturally lighted by day. Higher ceiling heights also provide natural sunlight to penetrate the inner areas of the building as in the case of the waiting area and the lobbies.
