Laboratory

The Thermal Ergonomics Laboratory is situated at the Lees Avenue campus of the University of Ottawa (see map)

Studies conducted are either:

    i) Laboratory-based (controlled conditions)
    ii) Field-based (e.g. athletes); or
    iii) Hospital-based (at the Children's Hospital of Eastern Ontario, Ottawa)


Equipment in the Thermal Ergonomics Laboratory includes:

For laboratory-based studies

  • Climate controlled chamber: Air temperature: +2.0˚C to +42.5˚C (±0.5°C); Absolute humidity: 5.0 to 41.5 Torr (±0.2 Torr)
  • Simultaneous dew point hygrometry (Viasala) at 3 sites measuring local sweat rate, sweat gland expulsion rate and sweat gland expulsion volume
  • Simultaneous core temperature measurements at 3 sites (esophageal, rectal and tympanic membrane)
  • 9-point skin temperature and local heat flow measurements
  • 2-site Laser-Doppler skin blood flow measurements
  • Whole-body sweat loss measurements to the nearest 1 g
  • Breath-by-breath metabolic cart (Vmax) measuring human ventilation, oxygen consumption, metabolic heat production
  • Semi-recumbent cycle ergometer
  • Upright cycle ergometer
  • Temperature controlled room (+10˚C to +40˚C)
  • Solar radiation simulator (100 to 550 W/m2)
  • Pyranometer (Kipp & Zonen)
  • High speed data acquisition system (National Instruments)
  • Liquid-conditioned cooling/heating garment (+5˚C to +40˚C)
  • Dual x-ray absorptiometry (DXA)*

* Through collaboration with Behavioural Metabolic Research Unit (Dr. E. Doucet)

 

For field studies

  • Ambulatory oxygen consumption and metabolic rate measurements system (COSMED k4b2)
  • Wireless core temperature telemetry system with ingestible temperature "pills" (HQ Inc)
  • Wireless skin temperature system (ibuttons)
  • Portable data acquisition system
  • Portable refractometer for measure urine specific gravity
  • Portable ambient environmental monitoring system (air velocity, radiant temperature, air temperature and ambient humidity)
  • Technical absorbent local sweat rate measurement system

 

For children's hospital-based studies

  • Whole-body evaporative heat loss measurements (to the nearest 0.01 g)
  • 6-point skin temperature and local heat flow measurements
  • 2-site Laser-Doppler skin blood flow measurements
  • Breath-by-breath metabolic cart measuring ventilation, oxygen consumption and metabolic heat production
  • Multi-site core temperature measurement system (nasophyarungeal, distal esophageal, rectal, tympanic membrane, and axillary
  • High speed data acquisition system (National Instruments)
