Passivhaus Bill proposed for Scottish Parliament

A proposed private member’s bill offers a timely opportunity for the Scottish Parliament to address the energy bill and climate crises. The Domestic Building Environmental Standards (Scotland) Bill is out for consultation until 27 July 2022

Alex Rowley, MSP for the Mid Scotland and Fife Region, is proposing the Bill which calls for all new housing in Scotland be built to the Passivhaus standard or to a Scottish equivalent. The Bill would apply to every new home built by councils, housing associations or the private sector.


A move to the Passivhaus ‘gold standard’ for all new-build homes would be radical, ambitious, practical and forward-thinking. It would future proof homes and prevent them from having to be retrofitted in the near future, upskill the construction sector and make Scotland a leading player with exportable skills and knowledge.

Alex Rowley MSP developed the proposed private member’s bill in response to the Scottish Climate Assembly recommendations. The recent Climate Assembly, set up by the Scottish Parliament,  presented its Recommendations for Action in which 97% of the Assembly voted in favour of the Passivhaus standard for new build projects in Scotland. ”Update building standards to ensure that, within the next 5 years, all new housing is built to Passivhaus standards (or an agreed Scottish equivalent), to create healthy homes for people while also taking into account whole life carbon costs and environmental impact” (page 16).

When many worry about the cost of living and accelerated cost of household energy bills, this proposal could not come at a better time for the country.

Building a net zero future

In June 2022 the Scottish Government announced its Building a net zero future strategy for new build homes, outlining its proposals for new building regulations, which  aim to 'cut emissions of all new-build homes by nearly a third'. The proposals, though a step in the right direction, do not include the rigorous targets, modelling methodology and certification quality assurance of the Passivhaus standard and so do not adequately address the issue of the building 'performance gap'.  Backed with over 30 years of international evidence, Passivhaus is a tried and tested solution to deliver net-zero-ready homes in Scotland optimised for a decarbonised grid and augmented for occupant health and wellbeing.

Alex Rowley MSP commented: "While we welcome the direction the Government are working in, the proposed new standards do not go far enough to tackle inefficient housing and reduce greenhouse gas emissions. They also miss a crucial aspect of our Bill which is the need to close the 'performance gap'". He goes onto say "Unless we introduce a verification process for energy efficiency, any changes to building regulations will remain inaccurate due to the gap in what an EPC rating suggests a building can achieve in terms of energy efficiency and what it actually achieves. It is a welcome improvement but it does not bring the standard of modelling and testing up to the same standard as Passivhaus quality standards".
