While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

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

The Daintree Building is a mixed-use, sustainable urban building on Pleasant’s Place, just off Camden St. Dublin , writes Brian O’Brien of Solearth Architects. Conceived in 1999 it has been a long development process—but by late September Daintree should be open for business and the ever innovative Daintree (Paper Co) Ltd will have a new home, one appropriate to the delightfulness of their products and their focus on nature’s generosity for their raw materials.

A new public park on the northside of Dublin combines wind power and sustainable water management with environmentally sound materials and strategies to boost biodiversity, making it a standard-bearer in urban design. Lenny Antonelli visited the site

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

As the main attraction at the Spring House and Garden Show in the RDS earlier this year, the “Eco House” claimed to offer the house buying public an entirely ecologically sound new home, with considerations for energy efficiency, the environment and health evident in the design, structure, materials and technologies showcased in the house. Construct Ireland spoke to the house’s architect, John Goulding and Director of Century Homes, Paul MacDonald, who explain not only the technological considerations but the environmental demand for such a project.

John Goulding, the architect on the Eco House, has been actively involved in researching energy efficient design for the past 18 years, working through UCD’s influential Energy Research Group, and has worked on several European Commission funded research and building demonstration projects. He explains to Construct Ireland’s Jeff Colley how the Eco House performs.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

If you are at all worried about keeping construction costs down and lengthening the useable lifespan of your building, it’s critical that energy performance is considered from the earliest stages of planning and design. John Hearne spoke to a number of leading Irish experts in sustainable design about following simple principles of orientation, form and layout to achieve substantial energy improvements for free

Geothermal heating is being specified by everyone from self-builders to developers to local authorities in increasing frequency across Ireland. As a relatively new technology in Ireland, it is crucial that anyone considering a geothermal system knows what they are getting into, to ensure an efficient, reliable heating source.

With over 20 years experience in this field in Ireland, Dr Paul Sikora, Vice Chairman of the Geothermal Association of Ireland explains what issues to be aware of when considering geothermal, from site suitability, to what to look for from suppliers and installers.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists
