Patrick Daly  highlights that the energy refurbishment of our existing housing stock must become a priority. Daly has undertaken a retrospective DEAP case study assessment of an example house and its BER ratings, with staggering results.

The unprecedented development seen in Ireland in the Celtic Tiger years was fueled by the availability of cheap, abundant fossil energy. As the boom ends, the state is attempting to boost the economy with investment in larger than ever infrastructural projects which will not benefit many of the tax payers who are funding them, and crucially don’t recognize the extent to which peak oil production will affect their viability, as Richard Douthwaite reveals.

Lenny Antonelli takes a look at some of the entrants of the 2009 Solar Decathlon, a competition that challenges university teams from around the world to design and build homes that capture the sun’s energy.

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building

At Tom Heneghan’s new development in Dromard, Belmullet, Co. Mayo, it’s a case of sixteen units down, eleven to go as Construct Ireland goes to press. Exceeding the thermal performance requirements of the Building Regulations by some 60%, these houses incorporate a range of innovative and affordable sustainable building technologies which together deliver high comfort, low energy living, as John Hearne reveals.

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

The Daintree Building is a mixed-use, sustainable urban building on Pleasant’s Place, just off Camden St. Dublin , writes Brian O’Brien of Solearth Architects.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

Innovative low energy construction is rarely recognised on a European scale. The Isover Energy Efficiency Awards are one exception — here are nominations from across the continent that were celebrated at the European awards ceremony in Barcelona on 2 June
