Real projects, on the record.
Interactive, fully-modelled case studies — the actual windows and interfaces, assessed to ISO 15099 for condensation, Mould Index and comfort across Australian climate zones. Play with the numbers yourself. We add new studies as projects are completed.
Featured
The VCA Window Alliance Taskforce sill study — eight Australian window systems, one glass, assessed side by side across three climate zones.
VCA Window Alliance — TIRS™ Sill Case Study
Eight fixed-sill window systems carrying the same double-silver low-E argon warm-edge glass, modelled for Mould Index, minimum surface temperature, fRsi and holistic comfort. Pick a climate zone on the map, compare any two systems side by side, and see which sills keep the mould out — and which don’t — in Sydney, Adelaide & Perth, Brisbane and Melbourne.
Rated Small, Built Big — WERS vs BTW
WERS deemed-to-satisfy rates one standard-size window; your project builds real ones. Because U-value is area-weighted, the window you install usually performs better than its rating. Drag the width and height on a fixed, an awning and a 2-panel slider — and see the configuration DTS can’t even rate.
More case studies
New studies are added as projects complete — residential retrofits, commercial façades and interface junctions across the climate-zone map.
uPVC systems — multi-section study
Several sections, multiple glass types and climate zones — coming soon.
Commercial façade interface
Curtain-wall junction condensation across climate zones — coming soon.
