Scotland's proposed Passivhaus standard: what designers and builders need to know

Scotland's approach to new-building energy performance is under review, with the Stage 2 consultation on its proposed Scottish equivalent to the Passivhaus standard closing on Friday 16 October 2026.

For architects, developers, engineers and contractors, the consultation raises questions that extend beyond individual product specifications. How should energy performance be measured? What should certification demonstrate? And how can the design and construction process provide greater confidence that buildings perform as intended?

The proposals are still being consulted on. They should not be treated as final requirements or described as making every new building a certified Passivhaus.
