Indoor Environmental Quality

LEED Addresses the following issues related to indoor environmental quality:

Indoor Air Quality

Occupants' well-being, comfort, and control

slide3

Indoor Environmental Quality

Critical Components

Indoor Air Quality

Thermal Comfort

Lighting

Acoustics

Mold Prevention

slide4

Indoor Environmental Quality

Goals of IEQ

Minimize the risk of building-related health problems

Maintain high-quality indoor environments

slide5

Indoor Environmental Quality

Strategies

Control pollutants

Introduce daylight and views

Provide occupants with controls

Acoustic and thermal comfort

slide6

Indoor Air Quality

Most Americans spend 90% of their time indoors. Levels of pollutants may be 200% to 500% higher indoors than outdoors, even in cities with a lot of air pollution

slide12

Strategies for Maintaining Indoor Air Quality

Prohibit smoking

Institute a no-smoking policy in the building and around building entrances, operable windows, and air intakes.

slide13

Strategies for Maintaining Indoor Air Quality

Ensure adequate ventilation

ASHRAE Standard 62.1

slide15

Install High-Efficiency Air Filters

Use filters with high Minimum Efficiency Reporting Value (MERV) ratings in ventilation equipment.

slide16

Strategies for Maintaining Indoor Air Quality

Specify Low-Emitting Materials

slide17

Strategies for Maintaining Indoor Air Quality

Protect Air Quality During Construction

Conduct a Building Flush-Out Before Occupancy

slide18

Strategies for Maintaining Indoor Air Quality

Control Measures:

HVAC Protection

Source Control

Pathway Interruption

Housekeeping

Scheduling

slide19

Strategies for Maintaining Indoor Air Quality

Install Entryway Grates

Place grilles, grates, or mats at least 10 feet long at all major entrances help to reduce the dust, dirt, and contaminants brought into the facility.

Develop cleaning procedures to properly maintain entryway systems.
