Some buildings, by their nature, tend to have larger energy requirements. Occupied around the clock, with occupants who feel the cold, nursing homes are a case in point. John Hearne visited a north Dublin building where a range of different sustainable technologies operate in tandem to deliver the residents’ heating and hot water requirements

Sustainable Energy Ireland was initially criticised by some quarters for the lack of vetting of renewable energy installers registered under the Greener Homes Scheme. However, the recent introduction of mandatory training for those on the register has also proven controversial, writes Lenny Antonelli.

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.

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.

The Department of Education has made its commitment to energy efficiency and CO2 reduction clear in developing and bringing into practice targets for primary school design that aim for less than half of the accepted good practice in the field. Project coordinator John Dolan, Senior Engineer with the Department of Education explains how this approach works within normal Departmental budgetary limits to create school buildings that show the way ahead for building designers.

Sustainable building at its best is about much more than just energy and carbon emissions, and involves considering location, form, orientation and the use of healthy, environmentally friendly materials.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

Interhabs, a company who build to the highly energy efficient Canadian Super E programme, have recently entered the Irish house building market.
Jeff Colley speaks to Ronan Long , General Manager of Interhabs Ireland, about the reasons why he believes Interhabs will bring energy efficient, comfortable, healthy homes to people across Ireland

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.
