Roof design and details can make or break an energy-efficient home.

Getting the Roof Right a Key to Good Design

Designing and building high-performance structures offers many chances for under-performing details, particularly when it comes to roofing.

Some design elements are problematic in and of themselves, and some components can be problematic unless they’re installed perfectly. Aesthetics are one thing, but practicality is another. For practical reasons, it is imperative to get roofing details right.

CAD systems make designing a complex roof fairly easy, but even if a roof performs fine in the modeling software, it still has to be built, insulated, and air-sealed to specs. A simple gable or hip roof, or as close a design as you can come up with, will reap rewards for the designer, builder, homeowner, and remodeler.

Making Roofs More Functional with BIPV-T Systems

New roof technology can provide shelter, electricity, and heat from a single roofing system.

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. ARENA CEO Ivor Frischknecht said the roofing system was designed specifically for Australia’s climate and building environments to ensure the PV systems were durable and robust. The companies are developing the systems for commercial sales.
