LEED 183

Rapidly renewable materials, credit no. 6 This is an interesting measure that
encourages the use of rapidly renewable natural and manufactured building materials.
Examples of natural materials include strawboards, woolen carpets, bamboo flooring,
cotton-based insulation, and poplar wood. Manufactured products may consist of
linoleum flooring, recycled glass, and concrete as an aggregate.
The point weight awarded for this measure is 1.

Certified wood, credit no. 7 The intent of this measure is to encourage the use
of wood-based materials. One point is credited for the use of wood-based materials
such as structural beams and framing and flooring materials that are certified by Forest
Council Guidelines (FSC).

INDOOR ENVIRONMENTAL QUALITY

Minimum indoor air quality (IAQ) performance, prerequisite no. 1 This pre-
requisite is established to ensure indoor air quality performance to maintain the health
and wellness of the occupants. One credit is awarded for adherence to ASHRAE build-
ing ventilation guidelines such as placement of HVAC intakes away from contaminated
air pollutant sources such as chimneys, smoke stacks, and exhaust vents.
The point weight awarded for this measure is 1.

Environmental tobacco smoke (ETS) control, prerequisite no. 2 This is a
prerequisite that mandates the provision of dedicated smoking areas within buildings,
which can effectively capture and remove tobacco and cigarette smoke from the build-
ing. To comply with this requirement, designated smoking rooms must be enclosed
and designed with impermeable walls and have a negative pressure (air being sucked
in rather than being pushed out) compared to the surrounding quarters. Upon comple-
tion of construction, designated smoking rooms are tested by the use of a tracer gas
method defined by ASHRAE standards, which impose a maximum of 1 percent tracer
gas escape from the ETS area. This measure is readily achieved by installing a sepa-
rate ventilation system that creates a slight negative room pressure.
The point weight awarded for this measure is 1.

Outdoor air delivery monitoring, credit no. 1 As the title implies, the intent
of this measure is to provide an alarm monitoring and notification system for indoor
and outdoor spaces. The maximum permitted carbon dioxide level is 530 parts per
million. To comply with the measure, HVAC systems are required to be equipped with
a carbon dioxide monitoring and annunciation system, which is usually a component
of building automation systems.
The point weight awarded for this measure is 1.

Increased ventilation, credit no. 2 This measure is intended for HVAC designs
to promote outdoor fresh air circulation for building occupants’ health and com-
fort. A credit of one point is awarded for adherence to the ASHRAE guideline for
