. Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices

Natural rubber flooring is a bio-based material that can contribute to the achievement of Option 2 of the Sourcing of Raw Materials credit, which requires using products that meet at least one of the responsible extraction criteria for at least 25%, by cost, of the total value of permanently installed building products in the project1. By meeting the Sustainable Agriculture Standard (SAN), the natural rubber flooring demonstrates that it has been produced in a way that conserves biodiversity, protects natural resources, and enhances social and economic well-being2. Therefore, the cost of the substituted flooring ($80,000) can be counted towards the credit threshold.

The system boundary that a building life cycle analysis must be defined to account for is the cradle-to-grave stage, which includes the production, construction, use, and end-of-life stages of the building. This stage covers all the inputs and outputs of the building system, such as materials, energy, water, emissions, waste, and maintenance.

New Construction is the appropriate rating system for a new mixed-use building with 300,000 ft2 (27 871 m2) of residential units, 150,000 ft2 (13 935 m2) hotel and 50,000 ft2 (4 645 m2) of retail space. According to the LEED rating system selection guidance1, the New Construction rating system applies to buildings that are being newly constructed or going through a major renovation, and that include any of the following use types: office, retail, hospitality, education, residential, warehouse and distribution centers, or data centers2. The New Construction rating system can also be used for mixed-use buildings that have more than one use type3. Since the project involves new construction of a mixed-use building with residential, hospitality, and retail uses, the New Construction rating system is the most suitable option. The other rating systems are not applicable because they are either specific to one use type (Retail and Hospitality) or to buildings that are not complete at the time of certification (Core and Shell Development).

The Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies aims to establish better quality indoor air for the building occupants that promotes their comfort and well-being1.This credit requires the project team to implement several strategies to reduce the exposure of occupants and HVAC systems to environmental tobacco smoke, airborne contaminants, and chemicals1.One of the strategies is to design and construct all interior partitions to full height (deck-to-deck) or provide a hard-lid ceiling for spaces where hazardous gases or chemicals may be present or used2.This strategy helps prevent the migration of contaminants from one space to another through the plenum3.A copy room is an example of such a space, as it may contain printers, copiers, toners, and solvents that can emit volatile organic compounds (VOCs) and particulate matter (PM) into the air4. Therefore, the project team can achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies by providing a hard-lid ceiling for the copy room.

. LEED Building Design and Construction: Healthcare has additional appliance and process water requirements in Water Efficiency Prerequisite, Indoor Water Use Reduction

LEED Building Design and Construction: New Construction and LEED Building Design and Construction: Healthcare have the same Water Efficiency credits, except for the Cooling Tower Water Use credit, which is only applicable to the former. However, the Indoor Water Use Reduction prerequisite differs between the two rating systems, as the Healthcare version requires additional calculations for appliance and process water use, such as medical equipment, laundry, and kitchen equipment.
