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.

Since establishing UCD’s Energy Research Group in 1975, the career of Professor J Owen Lewis has taken in the role of principal at the UCD College of Engineering, Mathematical and Physical Sciences, a Bord na Móna R&D directorship and expert roles advising EU research, national energy policy and building regulations. Appointed CEO of SEAI last year, Professor Lewis has been a champion of sustainable building since before the term existed. His selection combines a proto-green Alvar Aalto design, the reimagined Reichstag and an unusual academic building with two new cutting edge sustainable buildings.

Built on stilts, entirely encased in recycled newspaper insulation on all sides, and designed to be easily taken apart so that its constituent elements can be reused once it reaches its end of life, Portlaoise Locomotive Drivers Building could hardly be more green. But it is – it’s a certified passive house. Iarnród Éireann senior architect David Hughes explains how such a sustainable exemplar came to be.

Everyone agrees that the standard of building materials must be maintained but is localised technical certification resulting in a death of innovative and environmentally friendly building products and systems reaching the Irish market? Construct Ireland's Jason Walsh & Jeff Colley investigate.

The HARP database allows Building Energy Rating assessors to enter real performance data for heating appliances when calculating Building Energy Ratings rather than low default scores - but few renewable appliances are listed, and the industry appears confused and deterred by the application process. Lenny Antonelli investigates.

Marie Stamp, Senior Trade Commissioner at the Canadian Embassy, Dublin, discusses the merits of Super E home build.

Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike. Leading green designer Joseph Little of Joseph Little Architects investigates the particular problems associated with dry-lining single-leaf concrete block walls

Creating the right comfort in buildings for elderly people involves ensuring a warm internal environment, which typically results in high energy consumption. John Hearne visited the new Castle Gardens Retirement Village as it approached completion and found a project that combines complimentary low energy technologies, materials and design to deliver high levels of comfort whilst also keeping running costs, energy consumption and carbon emissions low
