Natural ventilation - does it work?

Such is the importance of ventilation, it’s only right and proper that the efficacy of innovative mechanical solutions such as heat recovery ventilation and demand controlled mechanical extract ventilation is established
based on robust, comprehensive evidence. But how does natural ventilation fare when subjected to the same degree of scrutiny, and can it work in low energy buildings?

Passive house goes large

Passive house is no longer just the preserve of the self-builder. With over 300 passive houses built to date in multi unit-schemes and a thousand more on the way – along with major non-domestic builds – increasing numbers of British & Irish developers are going passive. But how will the sector cope with upscaling, and will the most cost-conscious developers be attracted to the standard?

Unlocking investment in home retrofit

In spite of a consensus that most buildings need deep energy upgrades, both Ireland and the UK have barely scratched the surface. Joseph Curtin – one of Ireland’s leading energy policy wonks –discusses how to kick start en masse upgrade work.

The cost of building passive

Perhaps the most common argument against making passive house mainstream is that it costs too much to build. But as building regulations tighten and an increasingly competitive passive house sector emerges, does that argument hold water?

The passive house in a warming world

 The coming decades are expected to bring higher average temperatures, more extreme weather events – and possibly more cold snaps. But how are passive house buildings geared to adapt to a changing climate?

Bridging the building performance gap

Predicted energy usage seldom reflect actual consumption, whether in the case of typical stock or notionally low energy buildings. But how well does passive house turn theory into reality?
