Indoor Environmental Quality
1. Indoor Air Quality
Resources
- In a typical building, energy costs average $1.50 to $2.50
per square foot, while salaries exceed $200 per square foot.
Cutting energy use in half typically saves $1 per square
foot per year, while boosting productivity just 5% saves
more than $10 a square foot.
- The West Bend Mutual Insurance Co. of West Bend, WI built
a new 150,000 square foot building for 500 employees. It
was constructed in 1991 for $90 per square foot, when market
averages were $125 per square foot. The building has energy
efficient lighting, better windows and shell insulation,
and an efficient HVAC system. Compared to the old building,
productivity increased 16%. Office temperature complaints
dropped from 40 per day (at a documented cost of $25 per
call plus $300 in maintenance) to two per week.
- ASHRAE
Standards
|
Indoor air quality affects occupants' health, which can impact
absenteeism rates and employee productivity.
- Meet the minimum requirements of voluntary consensus standard
ASHRAE 62-1999, Ventilation for Acceptable Indoor Air Quality,
and approved Addenda (see ASHRAE 62-2001, Appendix H, for a complete
compilation of Addenda) using the Ventilation Rate Procedure.
(LEED™)
- Replace all filtration media immediately prior to occupancy
using filtration media that have a Minimum Efficiency Reporting
Value (MERV) of 13, as determined by ASHRAE 52.2-1999. (LEED™)
- Increase ventilation to exceed air change effectiveness of
0.9 per ASHRAE 129-1997. (LEED™)
- Provide for the use of natural ventilation in transition seasons.
Take advantage of cross ventilation, prevailing winds and stack
effects when possible.
- Provide direct exhaust for all spaces that generate moisture
and pollutants, including manufacturing, toilet and locker rooms,
copy rooms and rooms where chemicals and cleaners are stored.
- Provide mats or grills at entry areas to control dirt and dust.
- Prohibit smoking in the building. (LEED™)
- Consider a carbon dioxide monitoring system in spaces of variable
occupancy to provide feedback on space ventilation performance.
Specify initial operational set point parameters to ensure indoor
carbon dioxide levels do not exceed outdoor levels by more than
530 ppm at any time. (LEED™)
