The UK and Ireland’s oil heating industry says it has taken a “major step forward” in the use of biofuels in domestic oil boilers, with early tests concluding that hydrotreated vegetable oil (HVO) works in virtually all existing oil boilers.
Ahead of the Built Environment Summit (28-29 October) and COP26 (1-12 November), the Royal Institute of British Architects (RIBA) and Architects Declare have published a report demonstrating the critical role the sector must play in reducing greenhouse gas emissions.
In the #BuildingLife ambassador spotlight series, Passive House Plus is profiling leaders who have endorsed the Irish Green Building Council’s call to address the environmental impacts of buildings across their life-cycle..
The Department of Housing has come under criticism for draft guidelines which would prevent local authorities from setting sustainable building targets for buildings as a planning condition, with the passive house standard and low carbon cement directly referenced.
The Passive House Institute celebrated the low energy standard’s 30th birthday at the 25th International Passive House Conference in September. Around seven hundred participants registered for the conference, which mostly took place online due to Covid.
A new analysis of the exposure of London households to indoor pollutants highlights “systematic inequalities” in exposure, overwhelmingly driven by factors beyond the control of those people worst affected.
The winners of the international Passive House Award will be announced on Friday 10 September as part of the 25th International Passive House Conference, which is fully available online. Tickets to the conference are still available.

Retrokit, the Irish clean tech start-up whose software platform helps housing professionals to make evidence-based decisions for energy upgrade projects, has tailored its software for one-stop-shops managing retrofits under the national home energy upgrade programme.
Leading Irish window manufacturer Munster Joinery has emphasised the importance of environmental product declarations (EPDs) for reducing embodied carbon in buildings. The company sees reducing embodied carbon as the next major step for the industry after tackling operational energy.
A new school building in Cork City
built by Irish offsite timber specialist
Lidan Designs has achieved a remarkably
low embodied carbon score, according
to an analysis performed by sustainable
building consultant John Butler.
Despite the uncertainty created by the global pandemic, Galway based
ventilation manufacturer ProAir Systems has been busy
optimising its lineup of products and putting in place a number of
measures to enhance its…
A semi-detached house in Inchicore, Dublin
has seen its BER boosted from a G to an
A rating thanks to a deep retrofit by Dublinbased
retrofit contractor Energlaze and a new

Partel’s Alma Vert recycled structural panel
and Lunos Silvento ec exhaust system were
commended in the ‘best exterior product’, and
‘best renewable product’ categories respectively at
the Architects’ Choice Product Awards 2021, as
The National Construction Training Centre in County Laois is aiming to meet the challenge of training the huge number of skilled workers needed for Ireland’s planned housebuilding and deep retrofitting…
While there is much debate about whether we should prioritise retrofitting homes or installing heat pumps, the climate crisis means we may not have a choice but to do both as fast as possible, writes Toby Cambray.
In his latest column on the history of low energy building during the 20th century, Dr Marc
Ó Riain looks back at the Saskatchewan House, which was built in Canada in 1977, and
established the principle of prioritising energy demand reduction over active systems.
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.
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.
The government’s target of retrofitting half a million homes by 2030 may seem
daunting, but the Irish Green Building Council is working on a series of initiatives to
help make it a reality, as the group’s Marion Jammet reports.
In 2017 the government promised it would deliver 50,000 homes over the next five years as part of its Rebuilding Ireland programme. But figures from the first four years show it has fallen well short, writes Mel Reynolds.
The concept of building back better and greener, popular early in the pandemic, is now in danger of being abandoned in the rush to return to ‘normal’ — but we always have the power to shape what normal is, writes Dr Peter Rickaby.
As awareness of the urgency of the climate crisis grows, efforts to kickstart en masse deep energy efficiency interventions are gathering apace. But poorly conceived low energy building efforts can lead to unintended consequences including overheating – a risk that’s bound to grow as the world warms up. Phi Architecture co-founder Claire Jamieson details the risks and offers some solutions on how to create low energy buildings that are comfortable in summer and winter.
As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts...
Heat recovery ventilation is an invaluable way to maintain indoor air quality in low energy buildings and minimise the loss of precious heat, but there are several issues to address to ensure optimal performance. Ventilation expert Ian Mawditt, a technical advisor on Part F of England’s building regulations, has decades of experience in field investigations of indoor air quality and ventilation effectiveness. His guide, which focuses on centralised or ducted whole house heat recovery systems, is essential reading to anyone considering such a system.
Building physics take no prisoners. Anyone designing, constructing or upgrading the thermal envelope of a building to modern energy performance levels is duty bound to understand and minimise thermal bridging, or suffer the consequences. One-man thermal bridging encyclopaedia Andrew Lundberg of Passivate, who teaches thermal bridging analysis at Dublin Institute of Technology, gives some practical advice on why and how to tackle thermal bridging head on, and describes some of the leading innovations in thermally broken components.
