Within that framework, access floors have the potential to contribute to the following LEED-NC points:

Materials and Resources (MR)
13 total possible points; up to four points applicable to access floors:

• MR 4.1 ~ 4.2 25 or 50 percent Recycled Content of Materials 1-2 points

2. LEED-EB: The LEED Green Building Rating System for Existing Buildings (LEED-EB) is a set of performance standards for the sustainable operation of existing buildings. The LEED-EB criteria cover building operations and systems upgrades in existing buildings where the majority of interior or exterior surfaces remain unchanged. LEED-EB maximizes operational efficiency while minimizing environmental impacts. It provides a recognized, performance-based benchmark for building owners and operators to measure operations, improvements, and maintenance on a consistent scale. It is a road map for delivering economically profitable, environmentally responsible, healthy, and productive places to live and work, by addressing the following:

• Whole-building cleaning and maintenance issues including chemical use
• Ongoing indoor air quality (IAQ)
• Energy efficiency
• Water efficiency
• Recycling programs and facilities
• Exterior maintenance programs, and
• Systems upgrades to meet green building energy, water, IAQ, and lighting performance standards

LEED-EB is based on a total of85 points with award levels as follows:

Within this framework for existing buildings, access floors have the potential to contribute to the following LEED-EB points: Figure 10-Personal Control
