A project team wants to earn the LEED v4 'Sourcing of Raw Materials' credit using responsible extraction criteria. Which of the following practices would qualify a manufacturer?
Answer: Reporting environmental and social performance through a sustainability report verified by a third party
LEED v4 recognizes responsible extraction when manufacturers disclose environmental and social impacts through third-party verified reports or participate in recognized responsible sourcing programs.
In the context of LEED Materials and Resources, what does the term 'embodied carbon' refer to?
Answer: The greenhouse gas emissions associated with manufacturing, transporting, and installing building materials
Embodied carbon encompasses all greenhouse gas emissions associated with the material life cycle — extraction, manufacturing, transportation, and construction — not the building's operational energy use.
Which LEED credit would a project earn by documenting that at least 20 different permanently installed products have published EPDs following ISO 14044 standards?
Answer: Building Product Disclosure and Optimization — Environmental Product Declarations
The EPD credit specifically rewards use of products with published Environmental Product Declarations that follow ISO 14044 life cycle assessment standards.
A LEED project is salvaging doors and frames from a historic building being renovated. Where in the LEED rating system would credit for reusing these elements most likely apply?
Answer: Materials and Resources — Building Life-Cycle Impact Reduction
Reusing existing building elements such as doors, frames, and structural components reduces the need for new materials and is rewarded under the Building Life-Cycle Impact Reduction credit in Materials and Resources.
Under LEED v4, which of the following correctly describes a 'Declare' label in the context of Material Ingredients?
Answer: A voluntary manufacturer disclosure listing all chemical ingredients in a product
A Declare label is a voluntary ingredient transparency tool where manufacturers list all chemical ingredients in their products, accepted by LEED v4 as a path to earning the Material Ingredients credit.
What percentage of total waste (by weight or volume) must a project divert from landfill to achieve the higher threshold under LEED v4's Construction and Demolition Waste Management credit?
Answer: 75%
LEED v4 awards one point at 50% diversion and a second point at 75% diversion of total construction and demolition waste.
Which of the following material types is classified as 'bio-based' and could contribute to a LEED Materials and Resources credit related to responsible sourcing?
Answer: Bamboo flooring harvested from a certified sustainable source
Bio-based materials are derived from living organisms — bamboo is a rapidly renewable plant-based material that qualifies as bio-based and can earn credit when responsibly sourced.
