MR Credit 1.1: MR 1.1
Building Reuse: Maintain 75%

Like in the Water Efficiency category, many of the Materials and Resources credits maintain the
same intentions and implementations, but additional points may be achieved through higher
percentages or higher performance of the intention. MR1.1 and MR1.2 are EXACTLY the
same, except you can earn two points by achieving the 95% requirement in MR1.2.
Note that credit MR1.3 should be treated as a separate credit with different means of
implementation.

MR Credit 3.1: MR 3.1
Material Reuse – 5% Reused Items
Same as credit MR 3.2 , except for percentage of total construction material is reused items (10%
in Materials and Resources 3.2)
5% of Total Construction Material is from reused items
Intention:
• Reduce waste

MR Credit 3.1: MR 3.1
Material Reuse – 5% Reused Items
Implementation:
• Definition of Reuse: bring back to original capacity & reduce use of original sources
• Excludes:
– recycled items
– MEP (mechanical, electrical, plumbing)
– Elevator equipment
• Includes:
– salvaged items
• beams, floors, posts, paneling, doors and frames, cabinets, brick and decorative
items

3.1 through MR 7
– Reused items
– Refurbished items
MR Credit 3.1: MR 3.1
Material Reuse – 5% Reused Items
Implementation, continued:
• Calculation:
– Based on COST $$$
• replacement value vs. total cost of construction
– Total Materials Cost —> 2 options
» 45% construction cost (total construction cost of entire project
multiplied by 0.45)
OR
» actual materials cost ?????????????
• benefit of using actual material cost rather than default 45% is that
projects with < 45% actual materials cost would find it easier to
achieve to 5% and 10% (MR3-2) thresholds since equation of
percent reuse = cost or reuse divided by total material cost.
• FIXED items are not used for calculation (door becomes a door)

Recycled Content
– 10% Construction Material
from Recycled Items
MR Credit 4.1: MR 4.1
Recycled Content – 10% Construction Materials
from Recycled Items
Same as credit MR 3.1 , except for percentage of total construction material is reused items (5% in
Materials and Resources 3.1)
10% of Total Construction Material is from Recycled Items (post consumer + 1/2 pre-consumer)
Intention:
• Reduce impact from extraction and processing of virgin materials
• Increase use of recycled content in building
Implementation:
• There are two types of recycled material:
• Post Consumer: material already been used and will be reused for another application.
– examples: plastic, paper, glass, and metal
• Pre-Consumer: material from the manufacturer that has not been used and will NOT be
reused
– examples: wheat straw, sawdust, fly ash
MR Credit 4.1: MR 4.1
Recycled Content – 10% Construction Materials
from Recycled Items
Implementation, continued:
• To clarify, we must use materials with recycled content such that “the sum of post-consumer
recycled content plus one-half of the pre-consumer content constitutes at least 10% (20% for
MR 4.2) BASED ON COST, of the total value of the materials in the project.
• Total Materials Cost —> 2 options
– 45% construction cost (total construction cost of entire project multiplied by 0.45) OR
– Actual materials cost
• benefit of using actual material cost rather than default 45% is that projects with <
45% actual materials cost would find it easier to achieve the 10% and 20% (MR 4.2)
thresholds since equation of recycled content = total recycled content cost divided
by total material cost.
• Calculating Assembly Recycled Content (composed of multiple materials)
– consider percents by weight of post-consumer and pre-consumer recycled content.
