Awaab Ishak’s death shows that building physics are a life and death matter
Advances in building physics in recent years are leading to an ever-increasing understanding among experts of the risks that a litany of pollutants can pose to building occupants. But this has not stopped vulnerable people from living – and dying - in substandard buildings that exacerbate these risks. Urgent action is needed, Toby Cambray explains, to better communicate and decisively tackle the risks buildings can pose to their occupants.
Healthy Homes Ireland launches indoor environmental quality report
Healthy Homes Ireland (HHI) has published a series of recommendations for the improvement of indoor environmental quality (IEQ), including the creation of a cross-disciplinary national leadership body that will advocate for change and set goals.
Mainstreaming retrofit – a massive missed opportunity
The scale of the retrofit challenge facing the UK and Ireland will require an army of tradespeople to upgrade homes – leading many to the conclusion that a new retrofit industry needs to be built from scratch. But is a more realistic answer staring us in the face – a thriving existing industry of trusted local tradespeople, asks Dr Catrin Maby OBE.
Does nuclear have a role to play in decarbonising energy?
One zero carbon energy source has historically been vehemently opposed by environmentalists. But can nuclear power overcome the high-profile failures of its past, asks Dr. Marc O Riain, or has the technology missed the boat?
Whole life carbon of buildings: a pathway emerges
While significant progress continues to be made on reducing the carbon emissions associated with heating and powering buildings, the other part of whole life carbon calculation, embodied carbon, has proved more elusive. But that may be about to change, and quickly, as Stephen Barrett of the Irish Green Building Council (IGBC) explains.

The PH+ guides
The PH+ guide to air source heat pumps
As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts...

The PH+ guide to insulating foundations
While understanding wall and roof insulation is relatively straightforward, insulation under the ground floor can be a bit of a mystery by comparison. Not only is it buried in the ground, but there are notoriously tricky spots like the wall-floor junction that need to be detailed and insulated properly. And the design of your foundation often depends on site conditions and the type of structure you’re going to build, too. In this guide, we explain some different ways of insulating one of the most challenging parts of the building envelope.

The PH+ guide to thermal breaks
Building physics take no prisoners. Anyone designing, constructing or upgrading the thermal envelope of a building to modern energy performance levels is duty bound to understand and minimise thermal bridging, or suffer the consequences. One-man thermal bridging encyclopaedia Andrew Lundberg of Passivate, who teaches thermal bridging analysis at Dublin Institute of Technology, gives some practical advice on why and how to tackle thermal bridging head on, and describes some of the leading innovations in thermally broken components.
