NCC 2025: The Facade Calculator

V 1.2

Better Building has released version 1.2 of its NCC 2025 Facade Calculator, building on the original with more features and a wider set of export options, all aimed at meeting the code in a way that's simple to use but robust enough to stand behind.

It's built primarily for architects who want fast access to Deemed to Satisfy design pathways under NCC 2025, but it also does real work for sustainability consultants.

The tool makes clear just how demanding the reference building becomes under the J1V3 verification method once window to wall ratio climbs above 40%.

Which raises the obvious question. Are the days of large curtain wall glazing ratios numbered? Early signs point that way. If DTS won't carry a high-glazing design, the only real offset left is running the J1V3 pathway and leaning hard on optimised building services, and that's a significantly bigger undertaking than sticking within DTS limits from the outset.
