Might want to listen to Mike Naz, that's what professional home energy auditors do though a little more complicated, they seal the entryways pressurize the house and introduce a gas then they use gas detectors to see where the gas is leaking from. The airflow from a common draft is going to have a velocity so low that it's not practical meausre it, not at a single point at least.

Temperature and airspeed depend on government policies.

Values in Germany: Temperature +24°C, airspeed <0.5m/s
