Once poorly understood by the mainstream building industry, airtightness is now increasingly seen as one of the most crucial objectives on any building project. Not only is it vital for energy efficiency, it’s also key for thermal comfort and for protecting a building’s structure from dampness and mould. In this comprehensive guide to airtightness, we look at why it’s so important, how exactly it’s measured, and most importantly, how to achieve it on site.
The home of a local passive house builder, this super low energy home in County Mayo is inspired by traditional building forms in the west of Ireland — and it blitzed Ireland’s nearly zero energy building standard a whole five years before it was set to become mandatory.
Taking its cues from the original historic almshouse on site, St John’s Lichfield chose to build their new sheltered housing development for older persons to the passive house standard as part of high-quality design that emphasised community, calm and comfort.
Architect Donal Ryan’s new low energy home in Thurles, Co. Tipperary attempts to marry design and passive house principles, a fact that’s manifest in its minimally-glazed yet striking north-facing façade.
Built on a particularly exposed site near Chichester where winter temperatures plummet all too frequently – down as low as minus sixteen – the award-winning Curly House had to overcome several challenges.
Featured in a case study in Passive House Plus not long after it was completed in 2015, quantity surveyor John Carney’s passive house on the windswept but sunny Waterford coast has now been occupied for almost three years.
As demand for super-insulated and airtight building structures grows, insulating concrete formwork (ICF) is rapidly gaining popularity as a method of construction. But what exactly is ICF, what are its key advantages, and why is it so well suited to passive house and low energy construction?
This skilfully designed new passive house in Blackrock manages to be lightfilled and strikingly contemporary while taking its design inspiration from the very ordinary Dublin street on which it sits.
As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts to answer the key questions.
This unique sports and drama hall, inspired by the architecture of local buildings, was built to a new standard that aims to ensure buildings deliver all round health and comfort to their users.
