The Discomfort in the Room - Greengauge Greengauge Director and Passivhaus Certifier Paul Smith shares his thoughts on the PHI Low Energy Building Standard.

🤔What are your thoughts on the PHI LEB standard?

"It was not designed as a first-choice certification route for new buildings with full access to Passivhaus components in a mature market like the UK..."

@passivpaul.bsky.social shares his thoughts in our latest blog.

The Discomfort in the Room - Greengauge Greengauge Director and Passivhaus Certifier Paul Smith shares his thoughts on the PHI Low Energy Building Standard.

It was designed for buildings that nearly made it and fell at the last hurdle, not for designing buildings that threw the jockey off and galloped to the finish line for a failed victory.

#passivhausdesigners #passivhaus #enerphit | Paul Smith Forever blowing bubbles, Thermal bubbles in the ground.... The ground beneath a heated building is intent on creating a thermal 'bubble' or 'Lens' maybe for the purist. By winter, that stored warmth helps reduce the temperature difference driving floor heat loss. The ground is working for you, not against you. EnerPHit component method, ground-contact elements are assessed using heat loss/load, not U-value alone. Flip your thinking, not how much insulation can you cram in there, but what is optimal for any restrictions you face. Watch out for the impact of ground water and get your perimeter insulation bob-on.
