Together in Electric Dreams

The gradual decarbonisation of our electricity grids — as renewable energy is phased in, while coal and peat are phased out — coupled with the proliferation of new buildings with very limited heat demand, has some experts asking if heating our homes and offices directly with electricity is starting to make sense again. So is it time to bring back the dreaded storage heater?

Brecon Beacons stone cottage gets Enerphit treatment

18th century ruin becomes stylish low-energy home

Homeowners Anne and Patrick Jordan’s ambitious upgrade and extension project in County Kildare took the shell of an 18th century farmhouse and transformed it into an elegant family home with a striking-yet-sensitive modern extension — all while embracing a healthy and fabric-first approach to retrofit combined with clever heating system design that has brought them from a G to an A3 rating.

DIY Cork builder hits passive & NZEB with first self-build

Despite having no construction experience, self-builder Eamonn Fleming decided he could build a new family home more cheaply — and with better attention to detail — if he did it himself. And even though he didn’t set out to build a passive house, he managed to meet the standard while doing almost all of the work in conjunction with his father, while exceeding the targets of Ireland’s nearly zero energy building definition.

Norfolk straw-bale cottage aims for passive

Passive house design is often seen as belonging to the world of hi-tech construction — perhaps unfairly, seeing as it emphasises a good building fabric over bolt-on technologies. Straw-bale construction, meanwhile, is usually regarded as the preserve of only the most committed, do-it-yourself eco-builders. To some these two approaches appear to be chalk and cheese, but in fact they are inherently compatible, and more and more projects are now combining the maths-centred approach of passive house with the extensive use of natural materials. In the first of a series of case studies on passive straw-bale dwellings, Lenny Antonelli spoke to...

Simple and stunning Highlands passive house merges old and new

While embracing traditional farmstead design made it trickier for this new build home in the Scottish Highlands to meet the coveted passive house standard, mixing modern standards of super-insulation with vernacular farmhouse architecture ultimately led to the creation of a very special home for proprietors Jeanette and Jon Fenwick — one that picked up a coveted UK Passivhaus Award in 2016.

New build homes face emerging ventilation crisis

Despite increasing standards of insulation and airtightness, housing developers face few requirements to provide better ventilation and indoor air quality for new home buyers — beyond knocking extra holes in walls. But as reports of condensation and mould affecting new housing developments continue to surface in both the UK and Ireland, and research indicates many new homes may have poor indoor air quality, are developers finally waking up to the need for properly engineered ventilation systems?

SuperHomes scheme: a blueprint for cost-effective deep retrofit?

For a while now, schemes that aim to encourage the mass uptake of home energy upgrades — essential for cutting carbon emissions from our building stock — have tended to fall into two camps: those that focus on shallow measures like cavity wall insulation and new boilers, and deep retrofit like the Passive House Institute’s Enerphit standard. A new Irish retrofit scheme aims to point the way forward by bridging the gap between these two extremes.

Deep retrofit transforms big, complex South Dublin home

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.
