Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

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

In light of the failure of AER 5 and the widespread pessimism in the wind industry regarding converting AER 6 contracts into operating wind farms, we asked the six main political parties what their proposals are for the development of an Irish wind industry.

Architect Eva Murphyova creates a modern and sustainable take on the traditional farm settlement with the addition of a new envelope, timber frame extension and sustainable heat sources

Imagine moving into a house without a heating system – what would you do? Contact the developer and demand they put one in immediately? Call a solicitor and sue the builder? Or sit back and enjoy living in a house, designed to meet your expectations of comfort without any recourse to a space heating system. Jason Walsh met the people behind Ireland’s drive toward the passive house.

Construct Ireland investigates what measures the Irish government is undertaking to actively encourage the homeowner to switch to non-polluting renewable energy sources.

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.

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.

Many of the opportunities that trees offer for sustainable building are harnessed by a housing development in Ballymahon, Co. Longford which combines timber frame construction with recycled newspaper insulation and wood pellet heating. Adding in solar panels and attention to detail for airtightness, these low energy, low carbon homes reveal a developer who sees a bright future in going green. John Hearne visited the site to find out more.
