G rated Limerick semi-d upgraded to A3 with full envelope & heating system upgrade

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.

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli
