    Study Notes

    Indoor Environmental Quality (IEQ)

    • IEQ is an important factor in building design, influencing health, comfort, and performance
    • IEQ relates to the basic value of a building in terms of people, its functionality, ecological, and environmental value
    • Users' experiences are influenced by factors such as:
      • Thermal Comfort
      • Air Quality
      • Visual Comfort
      • Aural Comfort (acoustics)

    Thermal Comfort

    • Thermal comfort is a subjective assessment, meaning it varies per individual
    • Thermal comfort factors include:
      • Air temperature
      • Air velocity
      • Relative humidity
      • Mean radiant temperature
    • The user's metabolic rate influences thermal comfort, which is determined by their physical activity level
    • Clothing insulation also plays a role, with different types and levels of insulation affecting perceived temperature

    Lighting Environment

    • Daylight influences correlated color temperature (CCT), ranging from 3200 Kelvin (sunrise/sunset) to 20,000 Kelvin (deep blue sky)
    • Luminance ratios are important for workspace design, with a rule of thumb of 1:3:10 for workplace lighting
    • Adaptation to visual environments takes time, ranging from 20-30 minutes for bright areas to complete darkness and 5 minutes for the reverse

    View

    • A quality view includes:
      • Ground level features, such as people and activities
      • Sky visibility
      • Landscape components

    Light for Health

    • Excessive light exposure can negatively impact:
      • Circadian rhythm
      • Vision (damage from intense light sources)
    • Lighting should be used for safety and well-being
    • Light plays a role in circadian rhythm by influencing sleep-wake patterns and seasonal affective disorder (SAD)
