Dún Laoghaire-Rathdown’s passive house policy also leaves the door open for alternative approaches, provided their equivalence can be demonstrated. But what does this mean? 

Thanks to fabric-first energy performance approaches such as passive house, heating demand is collapsing. So how does district heating stack up in buildings which need such little heat? 

There was a time when governments thought that simply offering grants for cavity wall insulation and heating system upgrades would be enough to stimulate mass upgrade of our building stock. But ‘shallow’ measures such as these may not be sufficient to drastically cut carbon emissions and make a real difference to occupant comfort and health, and convincing homeowners to upgrade their homes to a much higher standard will require a clever mix of psychology and smart financing 

Dublin is on the verge of taking a giant leap forward for construction, with two major authorities in the region set to make the passive house standard mandatory for new buildings. Can Ireland’s mainstream building sector rise to this challenge, and what can it learn from experience of big passive house projects across the water in the UK? 

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?

A building’s airtightness test result isn’t just an indicator of its energy efficiency – it’s an unambiguous indicator of build quality. With a little care in design and on site, airtightness targets that may seem impossibly tough are anything but, argues leading architect and certified passive house designer Simon McGuinness.

Passive house is no longer just the preserve of the self-builder. With over 300 passive houses built to date in multi unit-schemes and a thousand more on the way – along with major non-domestic builds – increasing numbers of British & Irish developers are going passive. But how will the sector cope with upscaling, and will the most cost-conscious developers be attracted to the standard?

Progress on retrofitting Europe's building stock is sluggish, but there is a way out of the mire.

Brian Dowd, ESB’s products and services manager, talks about the company’s new energy strategy and the launch of the next phase of their Halo programme.

Semi-state business Bord Gáis have placed green innovation at the centre of their business strategy. As CEO John Mullins reveals, pay as you save and renewable energy will shape the company’s future.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

World record oil prices are being shattered so regularly that breaking news stories on the matter seem cliché, with other fossil energy sources heading in the same direction. Richard Douthwaite describes the first significant signs that Irish banks may be starting to take the issue on board regarding property lending.

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

Kirk Shanks, Senior Researcher at the Sustainability Research Development Group, the Focas Institute, DIT describes the development of this new sustainable generation.

With an economy fuelled by a government approach to planning that many people equate to a road building and house building free for all, it should come as no surprise that quality of life suffers

Everyone agrees that the standard of building materials must be maintained but is localised technical certification resulting in a death of innovative and environmentally friendly building products and systems reaching the Irish market? Construct Ireland's Jason Walsh & Jeff Colley investigate.

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.

Responding to the Department of Communications, Marine & Natural Resources’ Green Paper “Towards a Sustainable Energy Future for Ireland”, Mark Coyne, Technical Director of Dalkia Ireland, outlines the challenges and responses to the three main pillars of the Green Paper – sustainability, competitiveness and security of supply.
