Making Roofs More Functional with BIPV-T Systems

The days of underutilised, single-purpose roofs appear to be fading. New roof technology can provide shelter, electricity, and heat from a single roofing system.

Called a building integrated photovoltaic-thermal (BIPV-T) system, the new technology integrates painted standing-seam steel roof panels with thin-film photovoltaic panels and makes use of the sealed chamber between them for thermal energy.

BlueScope Steel and the Australian Renewable Energy Agency (ARENA) have recently installed Australia’s first prototype BIPV-T system at a home in Glebe.

The companies are developing the systems for commercial sales.
