Low Carbon
Timber frame and Ireland’s low-carbon future
Ireland’s construction sector is moving from energy-only performance towards whole-life carbon assessment. That means the carbon impact of materials, manufacturing, transport, construction, use and end-of-life will become increasingly important.
Timber frame offers one of the most immediate and scalable ways to reduce embodied carbon in new housing and buildings. It combines lower upfront carbon, long-term biogenic carbon storage, off-site manufacturing efficiency and strong alignment with emerging Irish and EU carbon requirements.
As Ireland moves from NZEB towards Zero Emission Buildings and Net Zero, timber frame can help clients and design teams make practical carbon reductions today.
Preparing the industry today for the carbon requirements of tomorrow.
Why Timber Frame?
Timber frame is a mainstream, proven construction method with strong carbon advantages. It uses a renewable structural material, supports off-site precision manufacturing and can reduce embodied carbon when compared with more carbon-intensive forms of construction.
Lower embodied carbon
Irish research and industry studies indicate that timber-frame homes can have lower embodied carbon than comparable masonry alternatives. The original draft references Irish studies showing timber-frame dwellings at approximately 15-16 tCO2e embodied carbon, with masonry equivalents above 18 tCO2e, and a comparative study indicating around 40% lower embodied carbon per square metre.
Biogenic carbon storage
Timber stores carbon absorbed during tree growth. In a building, this biogenic carbon remains locked into the timber for the life of the structure. The original draft notes that a typical Irish timber-frame home may store approximately 6-8 tonnes of CO2.
Supports whole-life carbon goals
As whole-life carbon reporting develops, material choice will become more important. Timber frame can support design teams responding to embodied-carbon limits, Whole-Life Carbon reporting, EPBD Recast GWP reporting, Home Performance Index requirements and ESG-led procurement.
Immediate and scalable impact
Timber frame is already established in Ireland and can be scaled using existing manufacturing expertise, design knowledge and supply chains. That makes it a practical route to reducing upfront carbon in new homes and buildings.
Carbon Policy Updates
Irish and EU policy is moving towards a stronger focus on whole-life carbon. This includes operational energy, embodied carbon, reporting requirements and future carbon limits for buildings.
National climate obligations
Ireland has legally binding climate targets and carbon budgets. Because the built environment is a major source of emissions, construction materials and methods will remain under increasing policy focus.
EPBD Recast and Whole-Life GWP
The revised Energy Performance of Buildings Directive introduces Whole-Life Global Warming Potential reporting requirements. The original draft notes that Ireland must prepare a national roadmap for Whole-Life Carbon reporting by January 2027, with Whole-Life GWP reporting expected to appear in BER processes for larger buildings from January 2028.
Timber in Construction Steering Group
The Department of Agriculture, Food and the Marine-led steering group is supporting work on national timber-use strategies, embodied-carbon research and policy recommendations.
Market and funder pressure
Developers, approved housing bodies and public-sector clients are increasingly asking for evidence such as EPDs, Bills of Materials, LCA inputs, responsible sourcing records, HPI documentation and carbon calculator outputs.
Roadmap to Net Zero
2025-2027: NZEB and transparency
The current focus is on NZEB performance, growing use of voluntary LCAs, wider adoption of carbon calculators and preparation for national Whole-Life Carbon reporting.
Passive House as a future-ready route
Passive House is not mandatory, but it is increasingly used by developers and approved housing bodies. Its emphasis on ultra-low energy use, airtightness and reduced performance gaps makes it a useful bridge between NZEB and Zero Emission Buildings.
2027-2032: LCA and Zero Emission Buildings
Whole-Life Carbon reporting is expected to expand, with large schemes likely to face stronger LCA requirements and embodied-carbon limits. ZEB standards will become increasingly important.
2032-2050: Net Zero
The longer-term direction is towards full carbon limits, lower-carbon public buildings, responsible timber supply chains, circular material use, lower-carbon manufacturing and national Net Zero by 2050.
