Description

Compliance with the BPI (using ALF) is no longer sufficient to demonstrate compliance with the H1/AS1 or H1/VM1 5th edition building thermal envelope requirements. At the same time, a BPI calculation is now unnecessary when using H1/AS1 or H1/VM1 5th edition. Refer H1/AS1 1.1.3.3 and H1/VM1 1.1.3.3.
The ALF tool will continue to be available as an informational tool until 3 November 2023.
Please ensure you have downloaded all your project reports before this date.
