Intended as a landmark not only architecturally, Áras Chill Dara sets an example for large scale sustainable building, as Construct Ireland’s Jason Walsh found out.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

Sustainable Energy Ireland was initially criticised by some quarters for the lack of vetting of renewable energy installers registered under the Greener Homes Scheme. However, the recent introduction of mandatory training for those on the register has also proven controversial, writes Lenny Antonelli.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

In this fifth & final article in the series, Joseph Little compares simulations of several internal insulation options on common wall types, with worrying conclusions

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.

Sustainable building at its best is about much more than just energy and carbon emissions, and involves considering location, form, orientation and the use of healthy, environmentally friendly materials.

Construct Ireland’s John Hearne discovers the growing shift towards making sites independent in terms of both water supply and wastewater treatment.

Adding to the list of developers aiming to deliver energy efficient housing, Cronan Nagle Construction are currently on site with 188 highly insulated, airtight homes in Ennis, co. Clare. The development, which also incorporates heat recovery ventilation and condensing gas boilers is surpassing the thermal requirements of Building Regulations by up to 45%, as John Hearne discovers.
