Passive house 30 years on: qualified success or brilliant failure?
As the stringent fabric-first, low energy standard enters its fourth decade, Guy Fowler asks what sort of impact it has made on the world, and where it should go from here.

The deep retrofit of this 1930s dwelling on the Hampshire coast provides a pitch-perfect example of how to transform old dwellings while preserving their original structure and minimising embodied carbon, utterly transforming the living space without the need for an extension, and creating a cosy home that uses two-thirds less energy than before.
A striking new oak-framed passive house in an area of outstanding natural beauty in the English countryside has just opened its doors to the public, and already there has been a flood of guests seeking to experience life in a passive house.
This Enerphit project in the suburbs of South Dublin has dramatically transformed and extended a dated 1970s dwelling by adding an extra storey, radically reducing its energy consumption and creating a smartly-designed, light filled family home and office.
Insulating our homes is critical and must be our first priority, but how do we get the rest of the way to zero carbon? Dr Peter Rickaby investigates the options…
We won’t be able to reduce the embodied carbon of construction fast enough just by switching to lower carbon materials, says Pat Barry of the Irish Green Building Council, so we urgently need smart design that allows us to build with less, and to create a genuine circular economy for building materials.
Does the energy rating of homes actually reflect their real-world performance? Dr Shane Colclough, vice chair of the Passive House Association of Ireland, outlines the growing importance of post-occupancy analysis.
This issue features a passive house hostel situated in the town of Zegama, on the route of the Camino de Santiago.
Under its new housing plan, the government wants the state to acquire more land for housebuilding. But why has it failed to use the vast land banks it already owns? Mel Reynolds runs the rule over the figures.
In recent years, as energy efficiency targets for new buildings have tightened, attention has turned to cutting the embodied carbon of buildings by switching from materials like concrete and steel to lower carbon alternatives like timber. But if we are serious about solving the ecological emergency as well as stabilising the climate, we must look even further than embodied carbon, and think more deeply about the core values we apply to materials and buildings, and the manner in which we use them.
