Old buildings are tricky to upgrade – especially if external insulation’s not allowed. Utilising a combination of cutting edge building physics and a carefully selected palette of insulation materials, one Victorian stone building has been upgraded to the Passive House Institute’s Enerphit standard, slashing heating demand by 90%
Assessment of thermal bridges is the low hanging fruit lining the path to passive house and low-energy building, according to leading thermal modeller Andy Lundberg of Passivate, who says that taking the time to understand thermal bridging and to minimise and calculate it properly is essential to delivering cost optimal low energy buildings without an Achilles heel.
This pioneering deep energy upgrade of a 1960s home in Wicklow will take place in phases over at least five years, with the aim of making it more affordable to go passive by renovating on a step-by-step basis.
Built from a simple palette of timber and concrete, this diminutive but architecturally unique home managed to meet the passive house standard despite a small and awkward site.
As people get older, their thermal energy need increases: elderly people tend to spend more time at home, and to feel the cold more. As one new sheltered housing scheme demonstrates, passive houses may be the answer.
This new home in Galway is inspired by local buildings but doesn’t look like anything else in the area, and delivers passive performance along with panoramic sea views.
One young Irish family has taken the decision to build their new home in Co Louth to the passive house standard. In the first of a series of columns, Nessa Duggan explains the thinking behind the decision to go passive.
The latest in a long line of affordable passive house schemes from trailblazing housing association Hastoe, this new development at Outwell, Norfolk features 15 brand new passive homes.
