Encompassing indoor-air quality (IAQ), thermal quality, and lighting quality, indoor environmental quality (IEQ) impacts the comfort, well-being, and productivity of building occupants. It is a “perceived” experience,1 one affected by factors such as space design, equipment vibration, acoustics, and aesthetics.
Codes and standards contain minimum requirements intended to ensure buildings do not impair occupant health and comfort. Environmental-quality optimization is a concept aimed at improvingoccupant health and comfort. As this article will discuss, by intelligently exceeding codes and standards, we not only get by, we get ahead.
It is important to note some environmental-quality-optimization measures can be implemented during lighting retrofits for little or no additional cost. Others can be adopted during interior renovation or through modification of HVAC systems and HVAC-system operation. Many such measures can perform double duty, also serving as part of an energy-management program.
