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)
