The familiar North Atlantic drizzle may be giving way to more forceful, building-battering rain. A new study warns of shifting patterns that will test the resilience of structures, writes Toby Cambray.

As electricity decarbonises, the case for switching from fossil fuel boilers to efficient use of electricity to heat buildings via heat pumps has become overwhelming. But in markets like the UK where electricity is far more expensive than the European average, and people on low incomes may be chronically underheating poorly insulated homes, could a drive to electrify heating exacerbate energy poverty?

Peter Rickaby looks back on an extraordinary career, the challenge of convincing people of the need for a new approach to buildings, and the people who helped him to do just that.

The retrofit market is messy, scuppered by knowledge and skills gaps, and inconsistent approaches. Ele George makes the case for industrialisation to level up the retrofit market.

One of Europe’s key climate breakthroughs came in the form of the EU’s nearly zero energy building target, as Dr. Marc Ó Riain explains in the latest part of his series on the history of low energy building.

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.

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.

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.

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.

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.

Recent analysis has suggested a slowdown in the property sector for 2024, but what impact might a drop in inflation have? Mel Reynolds runs the numbers.

It’s fair to say that green building wasn’t a thing in early 90s Ireland, which makes one extraordinary Dublin project from 1994 all the more remarkable, as Dr. Marc O Riain writes.

Shortlisted for the Stirling Prize in 2003, BedZed was a prominent example of architecture starting to pay attention to sustainability. But how well did it work? In the latest part of his series on the history of low energy architecture, Dr. Marc O Riain looks back at a landmark project.

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 scale of the retrofit challenge facing the UK and Ireland will require an army of tradespeople to upgrade homes – leading many to the conclusion that a new retrofit industry needs to be built from scratch. But is a more realistic answer staring us in the face – a thriving existing industry of trusted local tradespeople, asks Dr Catrin Maby OBE.

One zero carbon energy source has historically been vehemently opposed by environmentalists. But can nuclear power overcome the high-profile failures of its past, asks Dr. Marc O Riain, or has the technology missed the boat?

How flexible can heat pumps be to handle what may be inexactly defined heating demands, asks Toby Cambray?

The passive house camp recently took place from 26-29 September at South West College's passive house premium-certified Erne Campus and the Centre for Renewable Energy and Sustainable Technologies (CREST).

Over the last century architects have unwittingly played a key role in terms of climate collapse and a slew of linked catastrophic environmental and social harms. A new book aims to change that.

But doing retrofit well and at scale remains an enormous technical and financial challenge, writes Dr Peter Rickaby.

In the latest missive in his series on the history of low energy design, Dr Marc Ó'Riain looks to some wacky and wonderful experimentation in a project that aimed to transform public perception of Milton Keynes.

To kick start the new year, have a listen to co-founders Jeff Colley and Dan Hyde on what they've learned in the 20 years since our first issue came out.

In the aftermath of COP26, Dr Peter Rickaby asks what is the government’s plan to deliver the deep, whole-house, quality-assured retrofits needed to get us to net zero by 2050?

The energy crises of the 1970s did not prompt a major shift in Europe from foreign oil and gas towards energy efficiency and renewables. Will we learn this time around, wonders Dr Marc O Riain

There has been a sleuth of recent reports on how to retrofit Britain’s existing homes, but we must think deeper than the practical matter of reducing energy and carbon, to how we create beautiful places to live, writes Peter Rickaby.

Marc O Riain explores how policy on both side of the Atlantic in the 1980s sabotaged a nascent revolution in renewables and energy conservation.

As the stringent fabric-first, low energy standard enters its fourth decade, Guy Fowler asks what sort of impact it has made on the world, and where it should go from here.

How do underlays manage to let water vapour through while keeping the rain out? Toby Cambray delves into the physics…

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.
