Yes, Passivhaus would be an aspiration. Decent insulation gets you a long way, but to ventilate a house well, without excessive heat loss, you really want airtightness + MVHR. These are easily incorporated in a new build, but in the UK we are caught in the expensive-land, cheap-structure trap.

Underfloor heating is good, radiators are also still a good option for low energy/ passivhaus buildings. The key is to design the system well and run it off heat pump at low temperatures for high efficiency.
