An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

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.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack

Mandatory for virtually all building types since January of this year, Building Energy Ratings have been met with little fanfare. Construct Ireland proposes a cost-free method of levelling the marketplace by ensuring compliance and increasing awareness of the BERs legal status. Jason Walsh explains.

The emergence of climate change as a serious concern has helped create a burgeoning market for a vast range of eco technologies. All too often, however, the basic principles of sustainable design are ignored or misunderstood. Chris Croly of mechanical and electrical engineers Building Design Partnership describes the detail of a building which reveals a no-nonsense attention to sustainability.

A sustainable building must address more than energy, carbon or materials, argues Irish born architect Stephen Roe of up-and-coming London architects Roewu – it must respond to its environment. Not only does Roe’s design for the All Weather House achieve that, it boasts green materials, renewable heating and generous insulation too.

Germany has a reputation for high quality craftsmanship, an attention to detail and a positive attitude to sustainable and healthy housing. Jason Walsh visited a new German-built house in County Dublin to see if the expertise can be exported.

As interest in sustainable building continues to escalate, Construct Ireland is increasingly unearthing buildings that betray an ambition to break new ground under a plethora of green criteria. John Hearne visited one such house in County Louth, and found a project driven by passive house and BER scale-topping ambitions combined with on-site energy and water supply strategies and a commitment to the use of green materials

Many of the opportunities that trees offer for sustainable building are harnessed by a housing development in Ballymahon, Co. Longford which combines timber frame construction with recycled newspaper insulation and wood pellet heating. Adding in solar panels and attention to detail for airtightness, these low energy, low carbon homes reveal a developer who sees a bright future in going green. John Hearne visited the site to find out more.

With an economy fuelled by a government approach to planning that many people equate to a road building and house building free for all, it should come as no surprise that quality of life suffers
