Richard Douthwaite proposes a new bank-free, debt-free way of financing property purchase and development to get the market working again and clear up the mess left by the bubble.

Long-caricatured as resource destroying monsters clad in steel and glass, the skyscraper is rarely viewed as an environmentally sound form of architecture. Construct Ireland’s Jason Walsh looks at efforts underway to change that perception.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

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

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.
