Passivhaus Trust welcomes ‘important step’ towards implementing Scottish equivalent

THE Passivhaus Trust has hailed ‘encouraging signs’ after the Scottish Government laid amendments to the Building (Procedure) (Scotland) Regulations to enable the implementation of the Scottish equivalent to the Passivhaus standard.

The move meets the commitment made in 2022 to give effect to Alex Rowley MSP’s final proposal for a proposed ‘Domestic Building Environmental Standards (Scotland) Bill’. Scottish Building Standards has issued an accompanying statement, outlining the next steps for the implementation of the Scottish Passivhaus Equivalent policy.

The Passivhaus Trust said it welcomes amendments enabling better reporting of evidence to monitor compliance with relevant standards; Passivhaus certification being considered as an alternative ‘means of compliance’; and the proposed implementation timeframe, with the revised standards being published in early 2026 and becoming mandatory in early 2028

However, the organisation noted that the legislative amendments announced are ‘quite minimal in scope’, as many of the changes needed to implement a Scottish Passivhaus equivalent policy are already possible within existing building standards and do not require substantial legislative changes.

The Passivhaus Trust said it understands that the ‘fine details’ of the policy are still to be revealed. The outcome of the 2024 consultation process has yet to be announced and a further consultation in 2025 will determine specific changes to performance targets and supporting compliance processes. The Scottish Building Standards team has stated that its consultation analysis report and Scottish Government response will be published shortly.

In the next stage of proposals, the Passivhaus Trust revealed it wants to see absolute energy targets close to Passivhaus levels; a modelling tool with accuracy equivalent to PHPP (Passivhaus Planning Package); and details of training provision to upskill the industry as needed.

Sarah Lewis, research & policy director of the Passivhaus Trust, said, “Today’s announcement by the Scottish Government is an important first legislative step but we are still awaiting the fine details of what that policy will look like. We are hopeful that the recommendations we put forward in our consultation response will have been taken on board so that Scottish building standards have the accurate tools and absolute energy targets that would be essential for any standard aiming to be a Passivhaus equivalent.”
