The Indoor Environmental Quality Section of the LEED Rating System addresses issues ranging from ventilation effectiveness and pollutant source control to thermal comfort and day lighting. On average, approximately how much of their time do Americans spend indoors?
90%
Which strategy supports improved indoor air quality during operations and maintenance?

Thermal comfort guidelines for temperature, humidity, and control are stablished by?
ASHRAE 55-2010
Which of the following elements should be considered to facilitate communication in school classrooms?

A telemarketing firm with 300 employees plans to use a raised floor to reduce the costs of cable management and churn in a proposed open-plan office with shallow floor plate. The design includes underfloor air distribution for cooling and ventilation. The engineer noted that this system would allow the use of a floor-mounted operable diffuser for each workstation. A closer look revealed that the moderate supply air temperature required at these diffusers would reduce the amount of energy associated with cooling a consistently greater quantity of outside air. The architect pointed out that the underfloor air distribution would also eliminate large overhead ducts, which could, in this particular case, increase the interior floor-to-ceiling height. Given the information provided above, which LEED credits might these strategies contribute to?
- EQ Credit: Enhanced Indoor Air Quality Strategies - Increased Ventilation
- EQ Credit: Thermal Comfort - Thermal Control
- EQ Credit: Daylight
In order for an occupant survey to improve the triple bottom line of a project, what should occur after the survey results have been assessed?

- The building systems manual should be updated to include the survey results
-Corrective action should be taken to address any problems
