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

Assessing the Impact on Agriculture of Predicted Changes in Irish Climate by Dr Nicholas Holden

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.

Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.

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

A sustainable energy project in north Tipperary has the potential to create a pioneering green community – buildings are getting energy makeovers, grants are available for renewables and the ecovillage at Cloughjordan is under construction. But getting householders in the area to go green is still proving a hard sell, as Lenny Antonelli reports

Up to 150,000 workers are at potential risk of developing fatal lung cancer as a result of exposure to dangerously high levels of radiation, while a leading radon expert has cited ‘widespread confusion amongst employers’ regarding their legal requirements.

Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply
