Putin has not funded disruption and chaos across Europe and the UK solely to weaken his enemies. He also knows that disruption and chaos favour the far right. And the far right loves Putin. It will abandon Ukraine and build him a highway into Europe.

Ventilation? If absolute humidity lower outside than in. e.g. warm building in cold weather. Enthalpy exchanger (ERV) can remove moisture from fresh air but only if something else is removing moisture from indoor air. I think you know this so I may have misunderstood the question? Are you using ERV?

Nick Grant @ecominimalnick.bsky.social · 05/10/2026
MVHR no different to any vent in terms of moisture except you can keep it running when cold out without discomfort or high heating cost. If absolute humidity (not RH) higher out than in, then vent will lower RH indoors. Enthalpy heat exchangers can save energy with active dehumidification

Thanks, downloaded and will have a read. I wish I had more experience with low cost radical retrofit solutions. Frustrating that deep retrofit often ends up costing about the same as new build.

Running a workshop at the AECB conference next Friday. Should be fun assuming I've recovered from this horrid cold by then: aecb.net/wp-content/u... Though I'm sad that our workshop clashes with @ecominimalnick.bsky.social 's session and I'll miss that.
A workshop description: 

People First Retrofit, 
Marianne Heaslip and Helen Grimshaw

Arguments about whether retrofit should be 'fabric first' or 'heat pump and energy systems first' are getting tiresome. PPR take a different approach - focusing on people, context and understanding first. We'll explore through case studies and discussion what this means in a range of homes - and the implications for policy makers and practitioners.

I’ve reached the point - well actually, I reached it a while ago - where I’m militantly anti-AI. Fine - use it in bioscience labs and radiology where it might help analyse data more effectively. Use it sparingly for systems engineering. Everywhere else, it can fuck off.

I don’t live in a hot humid country with AC but humidity load is largely from outside air in this situation so good airtightness and perhaps ERV help. Dehumidification will depend on off-coil temperature and cooling power depends on that and airflow. Should be possible to balance.
