Access to quality transit is one of the criteria for the LEED v4 Location and Transportation category, which aims to reduce the environmental and human health impacts of transportation and promote sustainable site selection. By developing an urban site that is well-served by public transportation, the building owner can reduce the reliance on private vehicles, lower greenhouse gas emissions, and encourage alternative modes of travel123.

Soft surfaces contribute to a comfortable acoustic environment by absorbing sound waves and reducing noise levels. This can include items such as carpets, upholstered furniture, and acoustic ceiling tiles. In contrast, hard surfaces (like wood cabinets, hollow metal doors, or glass partitions)can reflect sound waves and increase noise levels. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Stone that is harvested and processed 80 mi (128.7 km) from the project site and purchased 75 mi (121 km) away is considered a local material because it meets the criteria of being extracted, harvested, recovered, or manufactured within 100 mi (160 km) of the project site. Local materials can help reduce environmental impacts associated with transportation, such as greenhouse gas emissions, air pollution, and energy consumption. Local materials can also support the local economy and community. LEED projects can earn credits for using local materials under the Materials and Resources category. References: Local Materialsin India3; LEED v4 BD+C Reference Guide, Materials and Resources, page 65

A Renewable Energy Certificate (REC) is a tradable commodity that represents proof that one unit of electricity was generated from a renewable energy source. RECs are used to track and trade renewable energy in the open market, providing an economic incentive for renewable energy generation. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
