How to prepare to deliver nearly zero energy buildings

In the second instalment of this column, architect and DIT lecturer Simon McGuinness outlines the key priorities for the industry to learn in order to deliver successful ultra low energy buildings in 2017 and beyond.

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?

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.

A2 rated Rathgar scheme goes high end but low energy

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

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 architect Fran Bradshaw of Anne Thorne Architects, who designed and built a straw-bale home for herself in Hickling, Norfolk two years ago — and aimed to meet the passive house standard while doing so, with only a single infrared electric panel as the building’s sole active heat source.

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?

Partel launches real-time U-value measurement kit

Passive house & low energy building product specialist Partel has announced that it is now offering real-time, physical U-value measurement with the company’s agency for the greenTEG U-value Kit.

Ireland’s largest passive scheme achieves world-leading airtightness

The first airtightness test has taken place at phase three of the Silken Park development at Citywest, which is set to be Ireland’s largest residential passive house scheme. A diagnostic initial blower door test, done when the external envelope was completed on one of the development’s show houses, took place on December 12 and delivered a worldbeating result of 0.16 air changes per hour (ACH), well inside the passive house standard of 0.6 ACH and the best result this magazine has ever noted for a masonry building.

Indoor air concerns about government’s healthy upgrade scheme

Questions have been raised about ventilation standards under the government’s new Warmth & Wellbeing scheme, which provides free energy efficiency upgrades to people over the age of 55 living in Dublin 12 and 24, who experience energy poverty and are also suffering from respiratory conditions.

2016 UK Passivhaus Conference gets into detail on delivery

2016’s UK Passivhaus Conference, which took place in London in October, was the biggest yet, with 300 delegates and another 100 visitors to the expo that ran in parallel. Also in attendance were students from half a dozen architecture schools, some of whom had risen before dawn for the chance to attend.
