Passivhaus Trust is a UK-based non-profit organisation promoting the Passivhaus building standard across the United Kingdom. It works with policymakers, industry bodies, manufacturers, professional institutes and academic centres to advance low-energy construction, retrofit protocols and quality assurance for buildings. The Trust positions itself at the intersection of technical guidance, certification frameworks and stakeholder engagement to accelerate adoption of high-performance building envelopes and mechanical systems.
The Trust was founded in 2010 amid a policy landscape shaped by the Climate Change Act 2008, rising concern about Energy Performance Certificate outcomes and growing interest in advanced envelope standards such as the Passivhaus Standard established in Darmstadt by Bo Adamson and Wolfgang Feist. Early activity engaged with institutions including the Department for Communities and Local Government and the Energy Saving Trust, and intersected with initiatives led by the UK Green Building Council and the Building Research Establishment. The organisation's timeline runs parallel to regulatory milestones such as revisions to the Building Regulations 2010 and retrofit programmes influenced by the European Union's energy directives, while interacting with projects promoted by local authorities like the Greater London Authority and research hubs at universities such as University College London, University of Cambridge, and University of Sheffield.
The Trust's mission emphasises quality-assured delivery of low-energy buildings through guidance, advocacy and certification support. It liaises with professional bodies including the Chartered Institute of Building, the Royal Institute of British Architects, the Chartered Institution of Building Services Engineers and the Royal Town Planning Institute. Activities include producing technical guidance aligned with international examples from organisations such as the Passivhaus Institut, coordinating with certification bodies like Passivhaus Trust Certified Professionals and engaging supply chains represented by trade organisations including the Federation of Master Builders and Construction Industry Council. The Trust also contributes to policy consultations involving the Department for Business, Energy and Industrial Strategy and stakeholder forums convened by the National Infrastructure Commission.
The Trust supports application of the Passivhaus Standard alongside complementary frameworks such as EnerPHit retrofit criteria and national standards influencing Building Regulations compliance. It interacts with certification schemes run by the Passivhaus Institut and works with UK-based certifiers, manufacturers certified under schemes recognised by the British Standards Institution, and testing facilities like those at the National Physical Laboratory and the BRE National Solar Centre. The Trust promotes best practice in airtightness testing standards used by practitioners accredited through bodies such as The Air Tightness Testing and Measurement Association and collaborates with monitoring networks exemplified by projects under the European Union Horizon 2020 programme.
The organisation runs training and accreditation pathways for designers, contractors and consultants, interfacing with academic programmes at institutions including University of Edinburgh, University of Nottingham, Loughborough University and vocational providers allied to the Construction Industry Training Board. It organises workshops, webinars and CPD events alongside partners like the Architects Registration Board and the Royal Academy of Engineering. The Trust's educational activities link to exemplar training modules developed in partnership with European counterparts such as the Austrian Society for Sustainable Building and German centres connected to the Fraunhofer Society.
The Trust publishes technical papers, case studies and guidance that reference performance monitoring from projects associated with labs and institutes such as the Building Research Establishment, Centre for the Built Environment, UCL Energy Institute and the Tyndall Centre for Climate Change Research. Its outputs contribute to literature cited in journals like Building Services Engineering Research and Technology, Energy and Buildings and conference proceedings of the International Passive House Conference and UK Concrete Congress. The Trust collaborates on funded research with partners in programmes administered by bodies such as Innovate UK and the Engineering and Physical Sciences Research Council.
The Trust provides support and oversight for demonstration projects across the UK, including retrofit pilots in municipal housing managed by authorities such as Manchester City Council and low-energy new builds in partnerships with housing providers like Peabody Trust and Clarion Housing Group. Its influence spans commercial developments where clients include developers registered with the Home Builders Federation and institutional projects for organisations like NHS England and the University of Oxford. Measured impacts include improvements in space heating demand, airtightness and indoor air quality reported in post-occupancy evaluations linked to case studies showcased at industry events organised by Ecobuild and the Passive House Plus conference.
The Trust is governed by a board and advisory panels drawing expertise from professional bodies such as the Royal Institution of Chartered Surveyors, trade organisations such as the National Federation of Builders and academic representatives from universities like Sheffield Hallam University and Cardiff University. Funding derives from membership subscriptions, training fees, grants from organisations including the Green Alliance and project funding secured through competitive bids to bodies such as Horizon Europe and Energy Systems Catapult. Strategic partnerships also involve collaborations with manufacturers associated with trade shows organised by UK Construction Week and standards organisations including the British Standards Institution.
