Discussing the project goals to help identify the credits and options that the team should attempt is an example of developing the LEED Scorecard.The LEED Scorecard is a tool that shows the potential points that a project can achieve under each credit category of the LEED rating system1.Developing the LEED Scorecard involves selecting the mostappropriate credits and options based on the project’s goals, location, budget, and design2.The scorecard helps the project team track their progress and prioritize their actions throughout the design and construction process1.References:

The scope of analysis in Materials and Resources Credit, Building Life-Cycle Impact Reduction, Option 4. Whole-Building Life-Cycle Assessment is a cradle-to-grave assessment.This means that the life cycle assessment (LCA) covers all stages of the building’s life cycle, from the extraction of raw materials (cradle) to the disposal or reuse of the building components at the end of their service life (grave)1.The LCA must include the following life cycle stages: product stage, construction process stage, use stage, and end-of-life stage2.The LCA must also account for the environmental impacts of the building’s structure and enclosure, as well as any other building elements that are permanently attached to and share service systems with the building2.References:

A multiple-zone system is a system that has one or more air handlers supplying conditioned air to more than one zone. A zone is a space or group of spaces within a building with heating and cooling requirements that are sufficiently similar so that desired conditions (e.g., temperature) can be maintained throughout using a single controlling device. The ventilation rate procedure calculations must be based on the multiple-zone system configuration because the HVAC system in the question serves different zones with different ventilation requirements.References: LEED v4 Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52

The Integrative Process Credit is a credit in LEED Building Design and Construction that supports high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems1. The credit requires project teams to perform analyses for both energy- and water-related systems before completing the schematic design, and to use the findings to inform the owner’s project requirements, basis of design, and design and construction documents1. The example given in the question is an illustration of how selecting a paint color with a higher light reflectance value can reduce the energy use and cost of lighting fixtures, which is an energy-related system. This strategy shows how the project team applied an integrative process to evaluate the impacts of different design options on the building performance and environmental benefits. Therefore, the correct answer is B. Integrative Process Credit.
