Hell's kitchen - Why cooking can destroy indoor air quality
When it comes to air pollution, we tend to worry most about things like traffic fumes and solid fuel burning — or when it comes to indoor air, condensation, damp and mould. But one of the biggest threats in the air we breathe comes from something we are exposed to almost every day, but rarely think about: cooking. John Hearne reports on the evidence for how cooking affects indoor air quality, and what we can do about it.

While the Covid-19 crisis has undoubtedly caused a huge amount of human suffering and economic damage, it has brought some upsides too. Mel Reynolds speculates on how much land prices may fall, and what the positive and negative impacts may be.
Environmental activism - tracing the roots of today's climate activism
While the green wave visible at ballot boxes and street marches in 2019 reflects an apparent escalation in public consciousness on the need for urgent, decisive environmental action, the roots of today’s environmental consciousness stretch back over half a century, explains Dr Marc Ó Riain.
How humanity can save itself from itself
We are in the grip of a global emergency. The science is clear, and thousands of lives have already been lost. The public are demanding firm and bold leadership, but a laissez-faire attitude on the part of western governments has delayed and watered down our response, with calamitous consequences.

Higher costs, less benefits - Why the enhanced social housing leasing model is a bad deal
The outgoing Fine Gael government devised an off balance sheet scheme to deliver social housing, but will it deliver value for money? Mel Reynolds crunches the numbers and finds the scheme may almost double the cost compared to a direct build – with no asset left once the lease ends.

The PH+ guides
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.

The PH+ guide to airtightness
Once poorly understood by the mainstream building industry, airtightness is now increasingly seen as one of the most crucial objectives on any building project. Not only is it vital for energy efficiency, it’s also key for thermal comfort and for protecting a building’s structure from dampness and mould. In this comprehensive guide to airtightness, we look at why it’s so important, how exactly it’s measured, and most importantly, how to achieve it on site.
