A number of Ireland’s largest house builders are turning to the passive house standard, to meet the need for proven approaches to delivering high performance sustainable buildings.

Irish homeowners can now borrow €5,000 to €75,000 at significantly lower interest rates to retrofit their homes, thanks to a new €500m government-backed scheme.

All new homes in Europe must meet binding embodied carbon reduction targets and produce zero on site emissions by 2030, due to changes led by Irish Green Party MEP Ciarán Cuffe.

Highly polluting cements are to be ruled out of public sector projects in Ireland from September, due to new government public procurement rules.

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.
