Must listen: Zero Ambitions Podcast

The focus is very much on keeping listeners engaged and informed – with a necessary dose of gallows humour.

Jeff’s co-hosts are user experience experts Alex Blondin and Dan Hyde (co-founder of Passive House Plus’s progenitor, Construct Ireland), who help to ensure the podcast couches the technical minutiae that Jeff loves in a manner that might chime with different kinds of users – designers, tradespeople, policymakers and building users.
