Results

• Monitoring results

• Set-up
• Two supply air windows (SAWs) ground floor
  kitchen and first floor bedroom both with same
  orientation
• PSV stacks in kitchen, ground floor bathroom and
  first floor landing
• Thermocouples monitor internal, cavity and outlet
  temperatures on both SAWs
• Dantec anemometers monitor all stack flow
  velocities
• Heat flux mats monitor external pane heat flux on
  both SAWs
• HOBO stand alone loggers monitor kitchen,
  bathroom and bedroom temperatures and humidity in
  both houses
