Reused materials are materials that have been used before and are incorporated into a new building without significant alteration1. They are different from recycled materials, which are materials that have been reprocessed into new products or materials2. Reused materials reduce the demand for new resources and the amount of waste sent to landfills1. LEED v4 encourages the use of reused materials by awarding points for Building Product Disclosure and Optimization - Sourcing of Raw Materials3.

According to LEED guidelines:

“Integrated Project Delivery phases: Pre-Design, Design, Bidding, Commissioning, Occupancy”

Commissioning aligns with these project phases for quality assurance and system verification.

Methane is a potent greenhouse gas that contributes to global warming and climate change. It is produced when organic waste decomposes anaerobically (without oxygen) in landfills1. Construction and demolition waste, which accounts for about a third of all solid waste generated in the world2, often contains a large amount of organic materials, such as wood, paper, and food waste1. Therefore, disposal of solid waste from building construction and operations in landfills has a substantial effect on methane emissions13. Incineration of solid waste also produces greenhouse gases, such as carbon dioxide, carbon monoxide, and hydrochloric acid, but at lower levels than landfilling45. Volatile organic compounds (VOCs) are not greenhouse gases, but they can react with other pollutants to form ozone, which is a greenhouse gas and a health hazard4.

According to a study completed by the Heschong Mahone Group, providing increased daylighting in schools can improve student test scores by 7%-18%. Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that sunlight (direct or indirect) can provideeffective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

LEED encouragesTransportation Demand Managementstrategies to reduce single-occupancy vehicle use when access to public transit is not available. One such strategy is:

“Encouraging carpooling… provides options to users in areas without access to transit.”

Offering preferred parking for single-use vehicles contradicts the intent, and LEED cannot require changes to local transit systems. Providing extra parking encourages single-occupancy vehicle use.

ASHRAE 62.1 is the standard for ventilation and acceptable indoor air quality in commercial and institutional buildings. It specifies the minimum ventilation rates and other measures to provide good indoor air quality for occupants. LEED v4 references ASHRAE 62.1 as a prerequisite for the Indoor Environmental Quality credit category.

ASHRAE 62.1 from the LEED v4 Green Associate Candidate Handbook, page 18.

Enhance Indoor Environmental Quality (IEQ) from the WBDG website, section on Adequate Ventilation and Exhaust.

A charrette is a strategy that can help build consensus for a project’s sustainability goals. A charrette is an intensive, collaborative, and creative workshop that brings together the project team and other stakeholders to define the project goals, scope, and strategies. A charrette can help to establish a common vision, identify synergies, and prioritize actions for a green building project. A charrette can also foster communication, trust, and buy-in among the participants13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

LEED certification is a process that evaluates the environmental performance and sustainability of a building project based on a set of rating systems. To earn LEED certification, a project must satisfy all the mandatory requirements, or prerequisites, of the chosen rating system, and earn a minimum number of points by meeting optional criteria, or credits. The number of points determines the level of certification: Certified (40-49 points), Silver (50-59 points), Gold (60-79 points), or Platinum (80+ points)123.

Employing a LEED AP (Accredited Professional) on the project team is not a requirement for LEED certification, but it can provide an advantage, as LEED APs have demonstrated their knowledge and expertise in green building and LEED rating systems. Having a LEED AP on the project team can also earn one point under the Integrative Process credit4.

Conducting a whole-building life-cycle assessment is not a requirement for LEED certification, but it can be an option for earning points under the Building Life-Cycle Impact Reduction credit. A life-cycle assessment is a method of evaluating the environmental impacts of a building over its entire life span, from extraction of materials to disposal or reuse3.

Earning a minimum of 50 points or meeting a prerequisite is not a sufficient condition for LEED certification, as it does not account for the other prerequisites or the level of certification. A project must meet all the prerequisites and earn at least 40 points to qualify for the lowest level of certification
