Construct Ireland investigates what measures the Irish government is undertaking to actively encourage the homeowner to switch to non-polluting renewable energy sources.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

“The thing to bear in mind is that even though it got knocked down, every single window sill went into another house, all the flooring and slates went into another house”, says Stephen Porter of Stonebrokers on the recent demolition of Lough na Vale in Sandymount.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

In many ways local authorities have become some of Ireland’s most progressive developers. Jason Walsh visited Ardee, County Louth to look at the latest in a long line of new civic offices that are redefining local government in sustainable terms.

As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.
