Americans spend approximately 90 percent of their time indoors1 and as a result their comfort, health, and work performance rely heavily on indoor environmental quality (IEQ).2 The indoor environment of an office facility is affected by a combination of conditions:
- Thermal Conditions (temperature and humidity)
- Lighting (amount, type, and color)
- Acoustics (noises and volume)
- Ventilation (air content and quality)
Maintaining each of these conditions within prescribed and standardized ranges will contribute to improved overall IEQ and occupant satisfaction. The personal ability to control these conditions also can lead to higher occupant satisfaction. Since IEQ is embedded in all aspects of building design & operations, any changes to building design or operational practices can have significant impacts on interior conditions. Thoughtful integration of an IEQ strategy can lead to healthier occupants and positively impact vision, mood, and comfort factors, thereby increasing performance, satisfaction and reducing absenteeism and healthcare costs.
