Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

A new extension to the EPA's headquarters in Wexford lives up to the organisation's aim of environmental protection, boasting passive ventilation and lighting, a host of green technologies and a sustainable approach to landscaping.

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.

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

Richard Douthwaite reveals that oil and gas peak are barely mentioned in the Government's recent energy Green Paper.

High levels of external insulation, abundant natural light and a minimalist approach to ventilation are ensuring that Malahide Lawn Tennis and Croquet Club is as green as its courts

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

Located in Oldtown, a hard to find country town in County Dublin, is a stunning new one-off house that not only manages to bring open-plan living to rural life, but also meets the onerous passive house standards using low impact materials. Jason Walsh visited the site as the house neared completion to find out more, an opportunity that Construct Ireland couldn’t pass up

Fears are growing amongst energy rating trainers that Ireland is running out of time to ensure building energy ratings are in place for existing homes at point of sale or rental from January. Jeff Colley spoke to SEI and to leading figures involved in energy rating training to find out more and shed some light on how homes will be assessed.
