Just outside the quiet rural town of Templepatrick, County Antrim, located ten miles north of Belfast, is a timber frame house that sets new standards for comfort and, the owners hope, sustainability. Jason Walsh visited the house and found a traditional aesthetic that belies its ultra modern sustainability features

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

If one was to draw a conclusion on how seriously sustainability is being taken at government level using the number of occurrences of the word "sustainable" in policy documents, housing guidelines and speeches from Ministers, it would come across that Ireland's on a sound sustainable footing.

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.

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.

As the organisation entrusted by OECD countries to predict future global energy supplies, the International Energy Agency’s projections have significant impact on energy policy around the world. IEA officials recently told The Guardian that the organisation’s figures on oil supply had been inflated and that oil peak is happening. Richard Douthwaite assesses the fall out

A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

Fingal County Council have clearly shown a laudable commitment to innovation by introducing a mandatory planning requirement for seven areas that all new developments reduce energy use and C02 emissions relating to space & water heating to 60% below Building Regulations requirements, with 30% of space & water heating coming from renewable energy sources

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible
