A recently completed pilot project by Cork Institute of Technology may be a model for bringing untenably inefficient and uncomfortable office buildings up to near zero energy performance levels.

Although preconceived notions about the existence of a passive house aesthetic still abound, trailblazing projects like the Ditchingham affordable housing scheme in Norfolk show that vernacular architecture & build methods can go hand-in-hand with passive performance.

Building a passive house school is a big achievement, but the team behind Oakmeadow Primary School in Wolverhampton have done something even more formidable — they built one when they weren't even asked to, and they did it for a conventional budget.

Built on a tricky site in the seaside town of Salthill, Co Galway, Ireland’s first semi-detached passive house development is designed to meet the needs of three generations from the same family.

A new timber frame house in Co Cork doesn't just meet the passive house standard, it does so for an impressive price.

Picking from some of the best current sustainable design the world has to offer, we profile a floating passive house currently moored in the Netherlands, a ground-breaking timber hybrid tower in Austria, a multi unit passive scheme in Malmö, and an Enerphit upgrade to a brutalist Connecticut home originally designed by one of Frank Lloyd Wright’s colleagues.

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. 

A new house in Wexford is the first in the country to achieve an A1 Building Energy Rating and certified passive house status – arguably making it the most energy efficient building yet built in Ireland. So why did a regulatory flaw risk rendering it non-compliant? 

Nothing drives innovation like adversity. Facing up to the prospect of scarce energy and other resources, we can take inspiration equally from the Inuit and the most avant-garde of passive house designers, as Sofie Pelsmakers reveals in her choice of six uniquely inspiring buildings from around the world.

Predicted energy usage seldom reflect actual consumption, whether in the case of typical stock or notionally low energy buildings. But how well does passive house turn theory into reality?

Do Irish buildings need the most heat when it's coldest, or when it's milder but windy? What consequences are there for how we build and heat them? And how airtight are Irish buildings anyway?

How do you make an old building liveable on Ireland’s wind ravaged Atlantic coast? The answer lies in the envelope, with airtightness, super insulation and the eradication of cold bridges

As Passive House Plus goes to press confirmation has come through that an extension to a nursing home in Celbridge, Co Kildare, has become the first healthcare building – and the first extension of any kind – to become certified passive.
