Energy Standards Review – Scottish Passivhaus Equivalent: Working Group

Overview

In response to Alex Rowley MSP’s Proposed Domestic Building Environmental Standards (Scotland) Bill, in December 2022, the then Minister for Zero Carbon Buildings, Active Travel and Tenants’ Rights confirmed that the Scottish Government would make legislation by December 2024 to deliver “a Scottish equivalent to the Passivhaus standard”.

To develop proposals, a further review of energy standards within building regulations was initiated at the beginning of 2023. The review considers standards for both new homes and new non-domestic buildings.

Remit

A working group to support the review was convened in June 2023, with an initial focus on two key outcomes:

• improvements to the setting of energy and environmental (ventilation) performance standards for new buildings, leading to lower energy demand (and reduced running costs) and a healthy indoor environment
• improvements to the design and construction process to give a greater assurance that compliance, and therefore the performance sought, is delivered in practice

The group’s role is to offer advice and expertise to the Scottish Government to help define how a Scottish equivalent to the Passivhaus standard will look.

The working group is co-chaired by Stephen Good (Chief Executive of BE-ST) and Stephen Garvin (Head of Building Standards, Scottish Government).

Consultation

The stage 1 consultation on our initial proposals for a Scottish equivalent to the Passivhaus standard ran between July and October 2024.

The consultation results were analysed and part 1 of the Scottish Government response  was published in December 2024.

The results from this consultation have informed relevant changes to regulations and themes for further consultation.

Part 2 of the Scottish Government response on the onward review was published in December 2025.

The stage 2 consultation on detailed proposals for specific changes to performance targets and supporting compliance processes was published on 23 July 2026 and will close on 16 October 2026.

Implementation

Following analysis of the stage 2 consultation results, updated guidance and approved calculation methodologies for the new standard are expected to be made available in Autumn 2027. To maintain a sufficient lead-in period for industry preparation, the implementation date will move from March 2028 to Autumn 2029.
