7 Stars on a Glazing-Heavy Noosa Home

The challenge

A coastal Noosa home designed around its outlook — large expanses of north- and east-facing glass framing the view. On paper it was exactly the kind of design that fails a standard glazing calculator, and the easy advice would have been to cut the window sizes down. For a home whose entire value is the outlook, that isn't a solution.

The approach

Rather than assessing the glazing in isolation, we modelled the whole thermal envelope — orientation, shading, glass performance, insulation and ventilation together. We specified high-performance glazing to reject summer heat, designed external shading tuned to the high summer sun while allowing low winter sun, and used the site's north-easterly breeze for cross-ventilation. Where the Deemed-to-Satisfy pathway still couldn't accommodate the glass, we prepared a Performance Solution demonstrating the home met the required performance by an alternative route.

The outcome

The home achieved its minimum 7-star NatHERS rating and Whole of Home requirement with the glazing — and the architecture — intact. The owners kept the view; the builder got a certifier-ready package; and nobody had to redraw the elevations.

Why it worked

Because the assessment started from the design intent rather than fighting it. Years in high-end residential design mean we know which levers to pull — glazing, shading, orientation and, when needed, a Performance Solution — to protect a design and still hit the number.
