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!
Oil alternatives
With oil prices remaining at ominously high levels in spite of sluggish economic growth figures and efforts by the International Energy Agency to release additional capacity, Ireland must act fast to cut oil usage. Why then, has the government withdrawn grants for renewables while continuing to subsidise oil and gas boilers?
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.

Gimme shelter
Designing a low energy building when you've got unlimited space is one thing – but what if you need to make your walls thin to maximise space on a small site in an architectural conservation area? Lenny Antonelli visited a new St Vincent De Paul sheltered housing project that fit a lot of sustainable features on to a small plot in Dublin's north inner city.
