and conserve a cultural identity, minimize waste, and reduce the environmental
impact. Note that another significant objective of this measure is to reduce the use of
newly manufactured material and associated transportation that ultimately result in
energy use and environmental pollution.
Credit is given for implementation of the following measures:

■ One credit for maintenance and reuse of 75 percent of the existing building.
■ Two credits for maintenance of 100 percent of the existing building structure shell
and the exterior skin (windows excluded).
■ Three credits for 100 percent maintenance of the building shell and 50 percent of
walls, floors, and the ceiling.

This simply means that the only replacements will be of electrical, mechanical,
plumbing, and door and window systems, which essentially boils down to a remodel-
ing project.

Construction waste management, credit no. 2 The principal purpose of this
measure is to recycle a significant portion of the demolition and land-clearing materi-
als, which calls for implementation of an on-site waste management plan. An inter-
esting component of this measure is that the donation of materials to a charitable
organization also constitutes waste management.
The two credits awarded under this measure include one point for recycling or sal-
vaging a minimum of 50 percent by weight of demolition material and two points for
salvage of 75 percent by weight of the construction and demolition debris and materials.

Material reuse, credit no. 3 This measure is intended to promote the use of recy-
cled materials, thus, reducing the adverse environmental impact caused by manufac-
turing and transporting new products. For using recycled materials in a construction,
one credit is given to the first 5 percent and a second point for a 10 percent total use.
Recycled materials used could range from wall paneling, cabinetry, bricks, construc-
tion wood, and even furniture.

Recycled content, credit no. 4 The intent of this measure is to encourage the
use of products that have been constructed from recycled material. One credit is given
if 25 percent of the building material contains some sort of recycled material or if there
is a minimum of 40 percent by weight use of so-called postindustrial material content.
A second point is awarded for an additional 25 percent recycled material use.

Regional materials, credit no. 5 The intent of this measure is to maximize
the use of locally manufactured products, which minimizes transportation and
thereby reduces environmental pollution. One point is awarded if 20 percent of the
material is manufactured within 500 miles of the project and another point is given
if the total recycled material use reaches 50 percent. Materials used in addition to
manufactured goods also include those that are harvested, such as rock and marble
from quarries.
