A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack

Ireland has been waiting for a green procurement plan in the public sector for two years. Jason Walsh looks at what the plan should include and why it is needed, now more than ever, and with sustainable building at its core.

In the third installment of a new feature on international green buildings, Lenny Antonelli takes a look at more innovative, sustainable and striking buildings from around the world.

John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

Up to 150,000 workers are at potential risk of developing fatal lung cancer as a result of exposure to dangerously high levels of radiation, while a leading radon expert has cited ‘widespread confusion amongst employers’ regarding their legal requirements.

If you are at all worried about keeping construction costs down and lengthening the useable lifespan of your building, it’s critical that energy performance is considered from the earliest stages of planning and design. John Hearne spoke to a number of leading Irish experts in sustainable design about following simple principles of orientation, form and layout to achieve substantial energy improvements for free

Built on stilts, entirely encased in recycled newspaper insulation on all sides, and designed to be easily taken apart so that its constituent elements can be reused once it reaches its end of life, Portlaoise Locomotive Drivers Building could hardly be more green. But it is – it’s a certified passive house. Iarnród Éireann senior architect David Hughes explains how such a sustainable exemplar came to be.

In light of Ireland’s poor performance in the recent European Environment Agency Report on drinking water quality, the issue of Ireland’s wastewater treatment from one off houses is poised to stay in the spotlight. Construct Ireland’s Pat Kennedy, environmental engineer, investigates.
