Culture shock & knowledge transfer
What are the consequences for the built environment, and the climate, of the lack of communication between research and industry, asks Dr Peter Rickaby – and what can be done about it?
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.
Is it too late for sustainability?
Despite the urgency with which radical action is required to transform our built environment, Dr Peter Rickaby says he has never been more optimistic about the possibility of change.
The schism in solar energy
In his latest column on the evolution of solar energy, Dr Marc Ó Riain looks at how the design approaches of architects and engineers diverged in the middle of the century.
Is the O’Devaney Gardens deal social vandalism?
The redevelopment of O’Devaney Gardens in Dublin City has grabbed headlines. Commentary has focused on the low levels of social housing proposed, high prices for private homes, and developer profit. But what is the cost to the state, asks Mel Reynolds, and is this sustainable?
Managing moisture: why we must learn the four Cs
Moisture problems are the Achilles heel of many new builds and retrofits, explains Dr Peter Rickaby – problems that can be exacerbated with poorly-conceived energy efficiency efforts, and which may become more prevalent due to climate breakdown.
Reflections on sustainable Nordic architecture
It’s no coincidence that Nordic countries are some of the most advanced in the world when it comes to low energy design. In this article, three assistant professors of architecture based in Denmark and Finland discuss areas where we can learn from our Nordic neighbours — and where we might return the favour.
Rebuilding Ireland mishap significantly inflating HAP figures
Mark Twain popularised the saying “There are three kinds of lies: lies, damned lies and statistics”. Mel Reynolds explains why Department of Housing statistics on HAP may be grossly inflating the state’s impact on tackling the housing crisis.
Editor's letter: Issue 30
Our editor Jeff Colley's editor's letter from issue 30 received some particularly lovely praise, with architect Steve Mardall reaching out to say: "Was moved to write to commend you on your editor’s letter in this issue 30. You’ve perfectly captured the essence of the totality of where we are as a planet and a race. And captured well that subtle consensus of denial and ‘othering’ it, that is a compelling force to fall in line with if one is not to be labelled as a righteous crank. Your words articulate some of my own not formally articulated thoughts, and offer me clarity...

Marc O'Riain: The golden age of solar water heating
Renewable energy technologies are often regarded as new and innovative, but in some instances their roots predate the oil age and go back to the start of the industrial revolution. Dr Marc Ó’Riain finds important insights in past failures of early solar thermal systems.
Is procurement stifling natural building materials?

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...
