John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

In issue 2 we reported on an innovative new energy bike scheme being implemented in Sligo. Its instigator, Wilhelm Bodewigs, got in touch to tell us about an interesting Tram system proposal for the county

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

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.

Tom Woolley, Professor of Architecture at Queens University Belfast and Editor of the Green Building Handbook, draws attention to the recent event which demonstrated the potential and importance of sustainable building in Ireland.

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.

Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.

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

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.
