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

Kirk Shanks, Senior Researcher at the Sustainability Research Development Group, the Focas Institute, DIT describes the development of this new sustainable generation.

When residents of Hollywood solemnly and publicly state the need to combat climate change, it is easy to reject as self-righteous, opportunistic bleating. When it’s a resident of Hollywood, County Wicklow, and the environmental statement is in the form of a poroton-block house infused with sustainable features, it provokes an altogether different response, as Lenny Antonelli reveals.

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

The Dwelling Energy Assessment Procedure (DEAP) is now the national methodology for creation of Building Energy Rating (BER) Certificates for new dwellings in Ireland, and is an important desk top tool for predicting the performance of projects at outline design stage.

A new development at Grange Lough, Rosslare, reveals that passive houses can be made Irish – both in terms of what they’re built with, and how they look.

Jason Walsh spoke to David Smith of O'Mahony Pike Architects about the practice's uniquely-designed show apartments for this year's Myhome.ie Spring House and Garden exhibition.
