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.

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

Our abundance of holiday homes and other vacant dwellings could be used to house Ukrainian refugees, writes Mel Reynolds.

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

Why is there is such antipathy towards putting ventilation at the forefront of our Covid prevention strategy, asks Residential Ventilation Association of Ireland chair and co-founder David McHugh.

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.

Addressing building life cycle emissions requires much deeper action than is currently planned, says Marion Jammet of the Irish Green Building Council.

Despite an increase in the construction of new homes, the number available for first-time buyers and families to purchase is falling.

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.

Insulating our homes is critical and must be our first priority, but how do we get the rest of the way to zero carbon? Dr Peter Rickaby investigates the options…

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.

Building physics expert Toby Cambray finds himself unconvinced by the merits of a new home in the Netherlands that has been 3D printed with concrete.

In his latest column, Dr Marc Ó Riain takes a look back at the some of the first projects to address the phenomena of thermal bridging and thermal bypass in buildings.

The government’s target of retrofitting half a million homes by 2030 may seem daunting, but the Irish Green Building Council is working on a series of initiatives to help make it a reality, as the group’s Marion Jammet reports.

In 2017 the government promised it would deliver 50,000 homes over the next five years as part of its Rebuilding Ireland programme. But figures from the first four years show it has fallen well short, writes Mel Reynolds.

A chance purchase on eBay leads buildings physics expert Toby Cambray to admire the aesthetics and mechanics of old scientific instruments.

The concept of building back better and greener, popular early in the pandemic, is now in danger of being abandoned in the rush to return to ‘normal’ — but we always have the power to shape what normal is, writes Dr Peter Rickaby.

In his latest column, Dr Marc O’Riain looks back at two American prototypes for the passive house standard that embraced heat pump technology as well as principles of superinsulation and airtightness.

With increasing attention turning to cutting carbon emissions from existing homes to meet carbon reduction targets, Duncan Smith, housing asset and energy strategy manager at Renfrewshire County Council in Scotland, argues that approaches which improve comfort and dramatically reduce energy bills must be front and centre.

It’s time to make the passive house standard a requirement of local development plans across Ireland, says Mel Reynolds.

Toby Cambray writes on the many lessons that the inimitable biscuit cake can teach us about how building materials deal with moisture.

Duncan Smith reflects on the social and architectural significance of Glasgow's tenement flats, and their potential place in a zero carbon future, as the city prepares to host COP 26. 

Dublin City Council built just 45 social housing units in 2019. In his latest column, Mel Reynolds analyses the state’s surprising reluctance to build its own homes.
