Deep retrofit transforms big, complex South Dublin home

At first glance, this sprawling house in Blackrock would appear to be a nightmare candidate for a deep energy upgrade — large and sprawling, and with a mix of structures built at different times and with different materials. But guided by the passive house standard, the team behind it managed to turn a G-rated energy guzzler into a healthy and very-low energy family home – complete with an A rating.

Ground-breaking housing scheme captures one developer’s journey to passive

The just-finished second phase of Durkan Residential’s ambitious Silken Park scheme in south-west Dublin bridges the gap between two extremes: while phase one was built to the 2002 building regulations, phase three — which will break ground next year — will comprise 59 passive certified units.

Stylish low energy house squeezed into South Dublin garden

Built in the back garden of two architects, this simple-but-elegant brick house in Blackrock faced the twin challenges of an extremely tight site and less-than-ideal orientation, but with rigorous attention to detail it came close to passive house levels - while delivering impressively low actual heating costs. 

Wicklow step-by-step retrofit reveals new way to go passive

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. 

Fermanagh schoolhouse reborn as passive family home

The abandoned husk of a 1960s school building sounds a very long way from a comfortable, ultra low energy family home. Thanks to a remarkable upgrade effort – influenced by reading Passive House Plus – one Fermanagh family are reaping the rewards of one such transformation. 

Affordable passive scheme that beggars belief

It may sound too good to be true, but a new scheme of semi-Ds in Co Wexford proves that passive houses can be remarkably affordable to buy – and that’s with net zero heating and hot water costs, and the soundproofing levels of a cinema.

 

Material impacts

For decades now, European countries have been regulating the amount of energy new buildings can consume for heating and electricity. But as these standards get ever tighter, is time to start controlling the embodied energy and wider environmental impact of building materials — and what’s the best way to do it?

New coastal ICF home goes passive at low costs

This house on the coast of County Waterford is built from an insulated concrete formwork shell that delivers an inherently warm and airtight construction, and easily exceeds passive house targets.
