However, as Richard Douthwaite warns, there is a real risk that smart metering may come in a form that benefits the electricity companies and not the end-user.

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 April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.

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.
