Construct Ireland and Century Homes present the need for Energy Labels before the Joint Oireachtas Committee

As fears grow amongst climate scientists that the world may be close to reaching a tipping point leading to runaway global warming, there’s a growing recognition that the forthcoming UN climate conference in Copenhagen must deliver dramatic and binding targets to cut carbon. According to Richard Douthwaite, the talks are unlikely to deliver sufficiently meaningful action.

A new development in the historic town of Thomastown, County Kilkenny brings the cutting edge of green innovation into a setting known for its medieval heritage. John Hearne visited the site, where a commitment to the environment is evident in sustainable design combined with everything from airtight detailing to technologies such as factory insulated timber frame, low energy windows, solar thermal, photovoltaic and heat recovery ventilation

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.

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.

Richard Douthwaite explains why the bailout may turn out to be a gift to Ireland, and offers some advice for dealing with a default.

The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.

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.
