Pass Judgement
Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

From the Construct Ireland archives
Welcome to the archive of Construct Ireland, the award-winning Irish green building magazine which spawned Passive House Plus.
The feature articles in these archives span from 2003 to 2011, including case studies on hundreds of Irish sustainable buildings and dozens of investigative pieces on everything from green design and building methods, to the economic arguments for low energy construction.
While these articles appeared in an Irish publication, the vast majority of the content is relevant to our new audience in the UK and further afield. That said, readers from some regions should take care when reading some of the design advice - lots of south facing glazing in New Zealand may not be the wisest choice, for instance.
Dip in, and enjoy!
Energy Auditing
An indepth look at the forthcoming Directive on the Energy Performance of Buildings by Jeff Colley.
Limerick civic precinct
With great attention to energy, materials and water, ABK Architects’ new civic precinct shows that smart green design can show no sign of compromise
Retrofitting investment
The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains
Malahide tennis club
High levels of external insulation, abundant natural light and a minimalist approach to ventilation are ensuring that Malahide Lawn Tennis and Croquet Club is as green as its courts
Breaking the mould - part II
The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.
Critical mass
Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.
Free Heat
As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable

Sustainable Sewage
There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.
