Why it still matters
The proposals could change how energy performance is calculated, evidenced and checked. The consultation closes on 16 October 2026, so there is still time for people who deliver the work to respond.
Who this affects
Architects, designers, housebuilders, building-services installers, energy assessors and trades working on new buildings or substantial alterations.
What to do now
- Read the sections that relate to your work rather than relying on headlines about “Passivhaus”.
- Consider whether the proposed evidence and compliance process is workable on real projects.
- Send a response by 16 October 2026 if the changes could affect your costs, sequencing or responsibilities.
What is being proposed?
The Scottish Government has opened the second-stage consultation on energy and environmental standards in the building regulations. It develops the plan for a Scottish equivalent to the Passivhaus standard, but it is not simply a proposal to require every building to obtain Passivhaus certification.
The consultation covers the performance measures, calculations, guidance and evidence that could sit behind the new standard. Those details will decide what changes on drawings, specifications, site records and completion checks.
Our take
Higher standards can produce better buildings, but only if the rules are clear and the evidence expected on site is realistic. Smaller firms should not leave the response entirely to large developers and professional bodies. If a requirement creates a practical problem, this is the point at which to explain it with a real example.
