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 will consider 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).
Engagement
Topic workshops in support of the review (hosted by Built Environment – Smarter Transformation).
Consultation
In July 2024, we published a consultation on our initial proposals for a Scottish equivalent to the Passivhaus standard. It sought views on the definition, approach and specific aspects of such changes.
The consultation is now closed and views received are being analysed. Once complete, an analysis report will be published.
The results from this consultation have informed relevant changes to regulations and themes for further consultation.
A second consultation on detailed proposals for specific changes to performance targets and supporting compliance processes will be launched in summer 2025.
Implementation
To enable the construction sector to prepare for the changes an implementation date of 31 March 2028 was set out in the amendments to regulations. It is the intent that changes to published guidance and approved calculation tools for the confirmed new standard will be made available in 2026.
