figures for air velocity and temperature in domestic and commercial properties

hi,

does any1 have any ides about the kind of figures for air velocity and temperature in domestic and commercial properties as i need to make a draught detector..... and depending on the temperature ranges and air velocity i need to select a suitable sensor.....

any thoughs/ideas/comments plz help.......

thnx

Use a cigarette.

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
