Passive house doesn't care about materials
One stubborn trope in some corners of green building is that passive house is so focused on energy performance that its advocates ignoring materials. Not so, argues Toby Cambray.
We need to talk about women and retrofit
Our efforts to retrofit homes across the UK and Ireland will be severely hampered unless we engage meaningfully with and empower women homeowners and professionals, writes Ellora Coupe, founder of Her Retrofit Space.
Energising Efficiency
In the latest piece in his series on the development of low energy building, Dr Marc Ó Riain describes the evolution and Impact of EPCs in Ireland and the UK.
If passive house is Everest, we’ve left base camp
The construction industry is moving in great numbers towards the passive house standard. In an adapted version of a speech at the Construction Industry Federation Conference in September, Passive House Association of Ireland chair Caroline Ashe Brady looks at the trek ahead.
In defense of fabric
As the grid gets greener and the case for heat pumps as a decarbonisation silver bullet becomes increasingly compelling, questions are starting to be asked about how far we need to go with retrofitting building fabric – or whether we need improve fabric at all. We ignore fabric at our peril, warns Toby Cambray.
Out of the blue - a passive revolution
Near the peak of the Celtic Tiger – at a time when developers were throwing up often sub-standard homes at a record pace, one self-build project pointed to a different approach, writes Dr Marc Ó Riain.

Awaab Ishak’s death shows that building physics are a life and death matter
Advances in building physics in recent years are leading to an ever-increasing understanding among experts of the risks that a litany of pollutants can pose to building occupants. But this has not stopped vulnerable people from living – and dying - in substandard buildings that exacerbate these risks. Urgent action is needed, Toby Cambray explains, to better communicate and decisively tackle the risks buildings can pose to their occupants.

The PH+ guides
The PH+ guide to airtightness
Once poorly understood by the mainstream building industry, airtightness is now increasingly seen as one of the most crucial objectives on any building project. Not only is it vital for energy efficiency, it’s also key for thermal comfort and for protecting a building’s structure from dampness and mould. In this comprehensive guide to airtightness, we look at why it’s so important, how exactly it’s measured, and most importantly, how to achieve it on site.

The PH+ guide to heat recovery ventilation
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.

The PH+ guide to insulating foundations
While understanding wall and roof insulation is relatively straightforward, insulation under the ground floor can be a bit of a mystery by comparison. Not only is it buried in the ground, but there are notoriously tricky spots like the wall-floor junction that need to be detailed and insulated properly. And the design of your foundation often depends on site conditions and the type of structure you’re going to build, too. In this guide, we explain some different ways of insulating one of the most challenging parts of the building envelope.
