Increasing the use of timber in construction is central to the work of a new steering group appointed by the Minister of State for Land Use and Biodiversity at the Department of Agriculture, Food and the Marine, Senator Pippa Hackett.

Mass timber comes into its own in terms of decarbonising tall buildings, which tend to rely on high embodied carbon materials such as steel and reinforced concrete. But regulatory change is needed to enable mass timber to fulfil its potential, as IGBC head of policy and advocacy Marion Jammet explains.

In recent years, as energy efficiency targets for new buildings have tightened, attention has turned to cutting the embodied carbon of buildings by switching from materials like concrete and steel to lower carbon alternatives like timber. But if we are serious about solving the ecological emergency as well as stabilising the climate, we must look even further than embodied carbon, and think more deeply about the core values we apply to materials and buildings, and the manner in which we use them.

This all-wood passive-certified home in the village of Kippen was built directly by its architect owners, who not only achieved the passive house standard but did so with an ecological approach that sought to use building materials ultra-efficiently and make it easy to deconstruct and recycle the building at the end of its life.

A beautifully detailed and rustic new passive house in the north of Scotland was built with a unique off-site construction system using local timber, and was created by a design-and-build firm that aims to put sustainability at the heart of everything it does.

For anyone interested in climate action, the government’s commitment to halve Ireland’s emissions by 2030 and to reach carbon neutrality by 2050 was one of the highlights of the year. But we won’t reach this objective focusing exclusively on energy efficiency — we must turn our attention to cutting embodied carbon too, and this wil be a major focus of the Irish Green Building Council's Better Homes conference next Friday, 27 November. 

Fuelled by the need to build quickly and to increasingly tight sustainability standards, the market for timber frame and mass timber construction is growing rapidly. This detailed guide covers many of the main established and emerging techniques, and looks at key issues to address if you’re considering a timber-based build.

Trunk Low Energy Building has announced a brand new venture, Trunk CLT, which provides a specialist structural engineering, fabrication and erection service for any client or architect who desires an inherently low energy cross laminated timber shell solution for their project 

Despite some setbacks, this passive house in Roscommon managed to meet the passive house standard for fairly standard costs — all while emphasising natural materials like untreated timber, cellulose and sheep’s wool.

A stunning location, thoughtful design and a certified passive house: a new home in the wooded hills of the Scottish Borders manages to have its cake and eat it too. 

Architect Michael Green says that by building timber skyscrapers, we can meet global housing demand without increasing carbon emissions. Check out his TED talk below.

The new issue of Passive House Plus includes our first ever Brettstapel building, a type of massive timber construction that uses no glues or nails, and that makes use of low grade timber otherwise unsuitable for construction. 

Truly efficient building design starts with sustainable materials, writes SmartPly's George Watson. Truly sustainable materials not only stand the test of time and make a positive contribution to the performance of buildings, he says, but have a low level of embodied energy and can be specified with confidence in their legal, sustainable and health and safety credentials.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

A log bungalow in rural Meath has been extended and given a total energy upgrade – and wood is at the heart of the renovation, with a timber frame extension and external insulation system along with a fresh log finish.

Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.

In the last decade timber has come to be seen one of the leading sustainable building materials, primarily through the growth of the timber frame market. Jason Walsh visited County Wexford to look at a growing use for the material – solid timber construction

Just outside the quiet rural town of Templepatrick, County Antrim, located ten miles north of Belfast, is a timber frame house that sets new standards for comfort and, the owners hope, sustainability. Jason Walsh visited the house and found a traditional aesthetic that belies its ultra modern sustainability features

Walter P. Toolan and Sons, a firm of solicitors in Ballinamore, County Leitrim has redeveloped its office with the intention of creating a healthy, environmentally sound building. Jason Walsh visited the office to find out more.

Architect Paul Leech explains why the new Navan Credit Union is arguably Ireland’s most innovative sustainable building to date, and outlines his hopes that the experience gained from this project can help the construction industry to realise sustainable building in Ireland.
