Specifications for new homes which fall short of energy performance targets in the Dwelling Energy Assessment Procedure software may nonetheless comply with Part L of the Irish Building Regulations, the Sustainable Energy Authority of Ireland has said. This is potentially a significant development for passive house, a proven ultra low energy building strategy which is often undermined by the relatively crude assumptions in the Irish regulatory guidance and Deap software.

What’s not to like about building regulations that demand 60% energy savings compared to boom time standards, and mandate the use of renewable energy? Glitches in the guidance documents, that’s what – glitches that unwittingly disincentivise energy efficiency best practice and risk causing building damage and compromising occupant health.
