Comfort Assessment

23:30 § Leave a comment

Pioneering work in the field of thermal comfort by Bedford (1936) and then Humphrey (1975) suggested the phenomenon of ‘adaptation’. It suggested that when given the opportunity to choose, people have the ability to adapt over very wide ranges of thermal environments.
The adaptive opportunity theory suggests that the threshold of discomfort relates to the extent to which users can adapt to changing environmental conditions by behavioural adjustments, acclimatization and expectation. Occupants accepts a greater variably in natural phenomenon than in artificial environmental systems.

Comfort Analysis Method


Baker devised a ‘Portable Array for the Measurement of Physical Ambience’s’ PAMPA  that subjectively evaluates ambient measurements. It is worn on the head of the user and therefore is non obstructive and non invasive of the occupants space. The device measures:
  • Ambient Temperature
  • Radiant Temperature
  • Relative Humidity
  • Air Movement
  • Illuminance Levels
  • Noise Level
  • Air Quality

The ’PAMPA’ allows data recording during a maximum time of 12 hours at 10 second intervals.
