The Passive House Institute celebrated the low energy standard’s 30th birthday at the 25th International Passive House Conference in September. Around seven hundred participants registered for the conference, which mostly took place online due to Covid.
A new analysis of the exposure of London households to indoor pollutants highlights “systematic inequalities” in exposure, overwhelmingly driven by factors beyond the control of those people worst affected.
The winners of the international Passive House Award will be announced on Friday 10 September as part of the 25th International Passive House Conference, which is fully available online. Tickets to the conference are still available.

In the #BuildingLife ambassador spotlight series, Passive House Plus is profiling leaders who have endorsed the Irish Green Building Council’s call to address the environmental impacts of buildings across their lifecycle.
With signs that the corporate world may be starting to move from greenwashing to genuinely grappling with sustainability via environmental, social and governance reporting (ESG), will this create opportunities for the widespread adoption of evidence-based sustainable building? Archie O’Donnell, Passive House Association of Ireland board member and environmental manager with i3PT, finds reasons for optimism.
While there is much debate about whether we should prioritise retrofitting homes or installing heat pumps, the climate crisis means we may not have a choice but to do both as fast as possible, writes Toby Cambray.
In his latest column on the history of low energy building during the 20th century, Dr Marc
Ó Riain looks back at the Saskatchewan House, which was built in Canada in 1977, and
established the principle of prioritising energy demand reduction over active systems.
We won’t be able to reduce the embodied carbon of construction fast enough just by switching to lower carbon materials, says Pat Barry of the Irish Green Building Council, so we urgently need smart design that allows us to build with less, and to create a genuine circular economy for building materials.
Does the energy rating of homes actually reflect their real-world performance? Dr Shane Colclough, vice chair of the Passive House Association of Ireland, outlines the growing importance of post-occupancy analysis.
Under its new housing plan, the government wants the state to acquire more land for housebuilding. But why has it failed to use the vast land banks it already owns? Mel Reynolds runs the rule over the figures.
As awareness of the urgency of the climate crisis grows, efforts to kickstart en masse deep energy efficiency interventions are gathering apace. But poorly conceived low energy building efforts can lead to unintended consequences including overheating – a risk that’s bound to grow as the world warms up. Phi Architecture co-founder Claire Jamieson details the risks and offers some solutions on how to create low energy buildings that are comfortable in summer and winter.
Heat recovery ventilation is an invaluable way to maintain indoor air quality in low energy buildings and minimise the loss of precious heat, but there are several issues to address to ensure optimal performance. Ventilation expert Ian Mawditt, a technical advisor on Part F of England’s building regulations, has decades of experience in field investigations of indoor air quality and ventilation effectiveness. His guide, which focuses on centralised or ducted whole house heat recovery systems, is essential reading to anyone considering such a system.
Cement is responsible for up to 8% of global carbon emissions, and in this guide, sustainable design expert Jay Stuart looks at ways to minimise its environmental impact through good design, and at some of the alternative, lower carbon cement and concrete products on the market.
