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.
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 business.
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
Viessmann air-to-water heat…
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…
Waterford-based high-performance window supplier and installer Zyle Fenster Ireland is now offering Triotherm thermal brackets from Prodomo Ireland as standard under door thresholds on all of its projects.
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.
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.
With increasing attention turning to cutting carbon emissions from existing homes to meet carbon reduction targets, Duncan Smith, housing asset and energy strategy manager at Renfrewshire County Council in Scotland, argues that approaches which improve comfort and dramatically reduce energy bills must be front and centre.
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.
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...
In the first in a new series of technical articles on some of the key technologies in sustainable building, John Hearne makes the case for wrapping buildings in an external insulation layer, and describes some of the main issues to watch out for.
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.
