As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.

Homeowners thinking of applying for Home Energy Saving scheme grants should pay close attention to a renovation project in Stillorgan, south Dublin. The refurbishment boasts every upgrade measure grant-aided under the scheme, including three types of wall insulation, a high efficiency boiler and sophisticated heating controls. Lenny Antonelli visited the house to find out more.

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.

Independent integrated sustainable design consultant Xavier Dubuisson explains why heed must be paid to a recent study on the threats that misjudged energy upgrade work can pose to indoor air quality.

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.
