FREE LEED (Leadership in Energy and Environmental Design Certification) Materials and Resources Questions and Answers

Question 1

A project team is pursuing the MR Credit: Building Product Disclosure and Optimization - Environmental Product Declarations. To meet the requirements for Option 1, what is the minimum number of different permanently installed products with qualifying EPDs that must be sourced from a minimum number of different manufacturers?

Accepted Answer

20 products from 5 manufacturers

Answer

For most BD+C projects, Option 1 of the EPD credit requires the use of at least 20 different permanently installed products that have qualifying EPDs, and these products must be sourced from at least five different manufacturers.

Question 2

When calculating the total diverted waste for the MR Credit: Construction and Demolition Waste Management, which of the following must be excluded from the calculation?

Accepted Answer

Excavated soil and land-clearing debris

Answer

LEED guidelines specifically state that excavated soil, land-clearing debris, and hazardous materials should be excluded from the calculations for this credit. Materials like salvaged items, recycled content, and wood-to-fuel are considered valid diversion pathways.

Question 3

A project team is prioritizing the use of products with certain environmental attributes to earn the MR Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials. Which of the following is a recognized attribute that contributes to this credit?

Accepted Answer

Products with certified wood content (e.g., FSC certified)

Answer

The Sourcing of Raw Materials credit focuses on leadership extraction practices. Recognized attributes include the use of materials that are reused, have recycled content, are bio-based, or have certified wood content from sources like the Forest Stewardship Council (FSC). HPDs relate to material ingredients, and SRI relates to heat island effect.

Question 4

For the MR Prerequisite: Storage and Collection of Recyclables, a project must provide an easily accessible, dedicated area for the collection and storage of materials for recycling. At a minimum, which set of materials must be included?

Accepted Answer

Paper, cardboard, glass, plastics, and metals

Answer

The prerequisite requires dedicated storage and collection for, at a minimum, paper, corrugated cardboard, glass, plastics, and metals. While collection of e-waste like batteries and lamps is also addressed, it's a separate requirement from the five core recyclable streams.

Question 5

A project is attempting to earn points under the MR Credit: Building Life-Cycle Impact Reduction by conducting a whole-building life-cycle assessment (LCA). To earn the maximum number of points under this credit's LCA pathway (Path 4), what must the project demonstrate in addition to impact reductions?

Accepted Answer

Incorporation of building reuse and/or salvaged materials

Answer

The highest point threshold for the whole-building LCA option (Path 4) requires demonstrating significant impact reductions (20% in GWP and 10% in two other categories) AND incorporating the reuse of existing building components or the use of salvaged materials.
