Significant Mortgage Savings for your Passive House

With the demand for eco-friendly buildings and, in particular Passivhaus (Passive House) growing across the UK and Europe; such building projects are benefiting from the well-established factor of supply and demand.


PHIUS Propose New Passive House Standard for the US

The Passive House Institute US (PHIUS) has just published their proposal for a new Passive House standard for the US. Frankly, we have a number of concerns regarding their proposed approach which would lead to a significant departure from the international standard already proven and validated across the globe. We feel the proposed 'standard' would be unworkable, would prevent comparing PHIUS' projects with Passive House projects around the world and is based on a thesis that is outdated given recent innovations by the Passive House Institute based in Germany.


Industry Peer Award for PHA Director Tomás O’Leary

Tomás was uncharacteristically lost for words at the closing plenary session of the recent See the Light Conference in Dublin when he was granted a Special Recognition Award by his industry peers. He is pictured here being presented with the award by past president of the European Parliament Pat Cox for his “outstanding contribution to the establishment of the Passive House standard in Ireland”. Tomás is hugely honoured to receive this award.
