Indoor Environmental Quality (IEQ)
(Continued)
Daylight and Views (2)
5.C8
Intent:
Provide a connection between indoor spaces and the outdoor environment through the introduction of sunlight
and views into the occupied areas of the building.
Requirement:
Achieve a minimum Daylight Factor of 2% (excluding all direct sunlight penetration) in 75% of all space
1
occupied for critical visual tasks, not including copy rooms, storage areas, mechanical, laundry, and other
low occupancy support areas. Exceptions include those spaces where tasks would be hindered by the use
of daylight or where accomplishing the specific tasks within a space would be enhanced by the direct
penetration of sunlight.
Direct line of sight to vision glazing from 90% of all regularly occupied spaces, not including copy rooms,
1
storage areas, mechanical, laundry, and other low occupancy support areas.
Technologies
Implement design strategies to provide access to daylight and views to the outdoors in a glare-free way using
/Strategies:
exterior sun shading, interior light shelves, and /or window treatments. Orient buildings to maximize daylighting
options. Consider shallow or narrow building footprints. Employ courtyards, atriums, clerestory windows,
skylights, and light shelves to achieve daylight penetration (from other than direct effect or direct rays from the
sun) deep into regularly occupied areas of the building.
Acoustic Environment /Noise Control
5.C9
Intent:
Provide appropriate acoustic conditions for user privacy and comfort.
Requirement:
Minimize environmental noise through appropriate use of insulation, sound-absorbing materials and noise
1
source isolation.
Technologies
Evaluate each occupied environment and determine the appropriate layout, materials and furnishings design.
/Strategies:
Facility In-Use IAQ Management Plan
5.C10
Intent:
Insure the effective management of facility air quality during its life.
Requirement:
Perform all of the following:
1
Develop an air quality action plan to include scheduled HVAC system cleaning.
Develop an air quality action plan to include education of occupants and facility managers on indoor
pollutants and their roles in preventing them.
Develop an air quality action plan to include permanent monitoring of supply and return air, and ambient
air at the fresh air intake, for carbon monoxide (CO), carbon dioxide (CO 2), total volatile organic
compounds (TVOCs), and particulates (including PM10).
Technologies
Provide action plan for periodic system maintenance, monitoring, occupant/manager training.
