Recycled Content: Calculating Points for LEED MR Credit 4
Question:
SK asks: Is there way to quantify the credits for a product using x % of recycled content would contribute to a LEED building?
Answer:
Hi SK:
Yes, review Materials & Resources (MR) Credit 4 - Recycled Content in the LEEDv.3 NC Reference Guide. The recycled content portion of a product is determined by weight.
The recycled content can be a fraction of the total product and is then calculated based on cost. 10% recycled content (based on cost) of the total value of all materials in the project gets you 1 LEED point, and 20% gets you 2 LEED points.

Energy used in cooling
Fri, 09/03/2010 - 06:33 — SK (not verified)Question #2: Also if the energy used in cooling is brought down by thermal insulation product , how can we map it to LEED credit/points?
This applies to the following
Fri, 09/03/2010 - 06:34 — Ed (not verified)This applies to the following EA prerequisites and credits:
1) EA Prerequisite 2 - Minimum Energy Performance
2) EA Credit 1 - Optimize Energy Performance
3) EA Credit 5/5.1/5.2 - Measurement & Verification
Compare the energy savings of your project to the baseline established. If your project ends up saving 10% in energy use compared to the average building, that meets EA Prerequisite 2 in LEEDv.3 New Construction.
Thermal insulation itself is a specified product that contributes to the energy performance of the building, lowering its Coefficient of Utilization (heat transfer). You can include thermal insulation product for MR Credit 4 Recycled Content as there are many products that include pre-consumer and post-consumer content.
