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

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.

Building a visitor centre at such an evocative site as the Cliffs of Moher, one of Ireland’s greatest tourist attractions must have been something of a challenge. By attempting to cater for visitors, the centre could so easily have ruined the rugged, barren landscape which makes people visit in the first place. John Hearne visited the new interpretive centre to discover a building which addresses this problem by becoming part of the landscape, whilst using eco technologies to reduce the building’s strain on the broader environment.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

Converting attic space can provide a relatively low cost means of increasing useable space, relative to the more arduous options of extending, or moving to a larger building. Duncan Stewart speaks to Construct Ireland about how best to approach Attic Conversions.

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

Sustainable architect Simon McGuinness describes a project in Dublin which is set to surpass the onerous standard using structural insulated panels.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.
