Winner in the sustainability category: Palram; Strandbroke House
The family home at Point Lookout on North Stradbroke Island in Australia was designed to contribute to the streetscape at night through the use of opaque multiwall polycarbonate sheeting. Polycarbonate sheeting was used for external wall cladding, balustrades and courtyard roofs. In all those areas, a 10-mm multiwall polycarbonate standing seam system in solar ice was implemented, said Palram in its submission.
The use of solar ice polycarbonate wall cladding ensured privacy while allowing extensive soft, diffused daylight into the house. Multiwall sheet was also extensively used on the deck where, as a balustrade infill, it again provided visual privacy to the deck from the street, and conversely, blocked the view of the bitumen street from the deck, focusing the occupants’ eyes to the ocean views beyond.
A polycarbonate screen provides shading and heat reduction characteristics, enabling comfortable use of the deck while maintaining natural light penetration. By that, energy savings are achieved twice: The use of natural daylight saves the need for artificial electricity through the daylight hours; the heat-blocking solar ice tint combined with the polycarbonate sheet's thermal insulation properties reduce the need for air conditioning.
