601 Quality of Construction Materials and Waste – Above Green

Intent

Design and construction practices that minimize the environmental impact of the building materials are incorporated, environmentally efficient building systems and materials are incorporated, and waste generated during construction is reduced.

601.1 - Conditioned Floor Area

Finished floor area of a dwelling unit or sleeping unit is limited. Finished floor area is calculated in accordance with ANSI Z765 for single family and ANSI/BOMA Z65.4 for multifamily buildings. Only the finished floor area for stories above grade plane is included in the calculation. [For every 100 square feet (9.29 m2) over 4,000 square feet (372 m2), one point is to be added to rating level points shown in Table 303, Category 7 for each rating level.]

less than or equal to 700 square feet (65 m²) (14 points)
less than or equal to 1,000 square feet (93 m²) (12 points)
less than or equal to 1,500 square feet (139 m²) (9 points)
less than or equal to 2,000 square feet (186 m²) (6 points)
less than or equal to 2,500 square feet (232 m²) (3 points)
greater than 4,000 square feet (372 m²) (N/A)
- For every 100 square feet (9.29 m²) 4,00 square feet (372 m²), one point is to be added to rating level points shown in Table 303, Category 7 for each rating level.

Note: For a multifamily building, a weighted average of the individual unit sizes is used for this practice.

601.2 - Material Usage

Structural systems are designed or construction techniques are implemented that reduce and optimize material usage.

Minimum structural member or element sizes necessary for strength and stiffness in accordance with advanced framing techniques or structural design standards are selected. (3 points)
- Required Documentation: Engineer’s statement that the intent of the practice has been met.
Higher-grade or higher-strength of the same materials than commonly specified for structural elements and components in the building are used and element or component sizes are reduced accordingly. (3 points)
- Required Documentation: Specifications showing higher grade materials.
Performance-based structural design is used to optimize lateral force-resisting systems. (3 points)
- Required Documentation: Engineer’s statement of design report showing performance-based design meeting the intent of the practice.

601.3 - Building Dimensions and Layouts

Building dimensions and layouts are designed to reduce material cuts and waste. This practice is used for a minimum of 80 percent of the following areas:

floor area (3 points)
wall area (3 points)
roof area (3 points)
cladding or siding area (3 points)
penetrations or trim area (1 point)

Required Documentation

Plans showing dimensions & layouts to minimize material usage and waste.

601.4 - Framing and Structural Plans

(4 points)

Detailed framing or structural plans, material quantity lists and on-site cut lists for framing, structural materials, and sheathing materials are provided.

601.5 - Prefabricated Components

(13 points MAX)

Precut or preassembled components, or panelized or precast assemblies are utilized for a minimum of 90 percent for the following system or building:

floor system (4 points)
wall system (4 points)
roof system (4 points)
modular construction for the entire building located above grade (13 points)
- Required Documentation: PO and documentation from producer.
manufactured home construction for the entire building located above grade (13 points)
- Required Documentation: PO and documentation from producer.

601.6 - Stacked Stories

(8 points MAX)

Stories above grade are stacked, such as in 1½-story, 2-story, or greater structures. The area of the upper story is a minimum of 50 percent of the area of the story below based on areas with a minimum ceiling height of 7 feet (2,134 mm).

first stacked story (4 points)
for each additional stacked story (2 points)

601.7 - Prefinished Materials

(12 points MAX)

Prefinished building materials or assemblies listed below have no additional site-applied finishing material are installed.

interior trim not requiring paint or stain
exterior trim not requiring paint or stain
window, skylight, and door assemblies not requiring paint or stain on one of the following surfaces:
- exterior surfaces
- interior surfaces
interior wall coverings or systems, floor systems, and/or ceiling systems not requiring paint or stain or other type of finishing application
exterior wall coverings or systems, floor system, and/or ceiling systems not requiring paint or stain or other type of finishing application

Points awarded for each type of material or assembly

(5 points) 90% or more of the installed building materials or assemblies listed above

(2 points) 50% - less than 90% of the installed building material or assembly listed above

(1 point) 35% - less than 50% of the installed building material or assembly listed above

Required Documentation

List of materials and manufacture’s literature (unless pre-finished is obvious) that do not get site finished. Note if used at 90%, 50%, or 35% level.

601.8 - Foundations

(3 points)

A foundation system that minimizes soil disturbance, excavation quantities, and material usage, such as frost-protected shallow foundations, isolated pier and pad foundations, deep foundations, post foundations, or helical piles is selected, designed, and constructed. The foundation is used on 50 percent or more of the building footprint.

Note: Indicate in the assigned Notes area the type designed and constructed: frost-protected shallow foundations, pier and pad foundations, post foundations, or other similar foundation type.
