The PH+ guide to overheating
As awareness of the urgency of the climate crisis grows, efforts to kickstart en masse deep energy efficiency interventions are gathering apace. But poorly conceived low energy building efforts can lead to unintended consequences including overheating – a risk that’s bound to grow as the world warms up. Phi Architecture co-founder Claire Jamieson details the risks and offers some solutions on how to create low energy buildings that are comfortable in summer and winter.

The PH+ guide to heat recovery ventilation
Heat recovery ventilation is an invaluable way to maintain indoor air quality in low energy buildings and minimise the loss of precious heat, but there are several issues to address to ensure optimal performance. Ventilation expert Ian Mawditt, a technical advisor on Part F of England’s building regulations, has decades of experience in field investigations of indoor air quality and ventilation effectiveness. His guide, which focuses on centralised or ducted whole house heat recovery systems, is essential reading to anyone considering such a system.

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...

Retrofit redux: Catching up with A3
The upgrade of Ireland's retrofit target to A3 marks a critical step forward, bridging the gap between energy modelling and real-world performance, explains Dr. Marc Ó Riain.
Energy poverty and electric heating
As electricity decarbonises, the case for switching from fossil fuel boilers to efficient use of electricity to heat buildings via heat pumps has become overwhelming. But in markets like the UK where electricity is far more expensive than the European average, and people on low incomes may be chronically underheating poorly insulated homes, could a drive to electrify heating exacerbate energy poverty?
Three books and a taxi ride
Peter Rickaby looks back on an extraordinary career, the challenge of convincing people of the need for a new approach to buildings, and the people who helped him to do just that.
The transformative power of industrialised retrofit
The retrofit market is messy, scuppered by knowledge and skills gaps, and inconsistent approaches. Ele George makes the case for industrialisation to level up the retrofit market.
Tripling EU / UK Energy Efficiency Policy: the NZEB
One of Europe’s key climate breakthroughs came in the form of the EU’s nearly zero energy building target, as Dr. Marc Ó Riain explains in the latest part of his series on the history of low energy building.
Passive house doesn't care about materials
One stubborn trope in some corners of green building is that passive house is so focused on energy performance that its advocates ignoring materials. Not so, argues Toby Cambray.
We need to talk about women and retrofit
Our efforts to retrofit homes across the UK and Ireland will be severely hampered unless we engage meaningfully with and empower women homeowners and professionals, writes Ellora Coupe, founder of Her Retrofit Space.

In defense of fabric
As the grid gets greener and the case for heat pumps as a decarbonisation silver bullet becomes increasingly compelling, questions are starting to be asked about how far we need to go with retrofitting building fabric – or whether we need improve fabric at all. We ignore fabric at our peril, warns Toby Cambray.
