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.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.

Hugh Dorrian, member of the Main Committee of the recently launched Building Limes Forum Ireland reveals lime is regaining ground as a key material not only in conservation projects, but in new build.
