The Facility Manager is typically responsible for monitoring ongoing energy performance over the life of a building. They oversee the operation and maintenance of building systems, including HVAC, lighting, and other energy-using equipment, and can implement energy management strategies to optimize performance. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Life-cycle assessment is the correct answer because it evaluates environmental impacts across a product’s or project’s life cycle. This includes raw material extraction, manufacturing, transportation, installation, use, maintenance, and end-of-life disposal or recovery. In LEED Materials and Resources, life-cycle thinking helps project teams reduce embodied environmental impacts and select materials or building systems with lower burdens. An Environmental Product Declaration may report life-cycle assessment results for a product, but it is not the general process named in the question. Sustainable Sites planning focuses on land, habitat, rainwater, heat island reduction, and site impacts. Life-cycle costing is different because it evaluates economic performance over time, including initial cost, operation, maintenance, replacement, and savings, rather than environmental impacts.

According to the LeadingGreen Guide:

“Individual controls for lighting have a significant effect on occupants’ comfort. Meeting the unique needs of each occupant can be accomplished through effective design of lighting controls…”

LEED credits under EQc6 emphasize providing lighting comfort and energy savings through such controls.

Designing an effective ventilation system is the best answer because ventilation directly supports Indoor Environmental Quality. LEED EQ focuses on occupant health, comfort, and well-being through strategies such as outdoor air ventilation, indoor air quality management, low-emitting materials, thermal comfort, daylight, views, and acoustics. A properly designed ventilation system supplies adequate outdoor air, helps dilute indoor contaminants, and supports healthier occupied spaces. Energy-efficient lighting and HVAC systems are valuable, but they relate more directly to Energy and Atmosphere unless they specifically improve occupant comfort or air quality. Solar panels provide renewable energy but do not directly improve indoor environmental conditions. Increasing parking area does not support IEQ and may increase site impacts. Effective ventilation is central to healthy indoor space design.

According to the EPA and emphasized by LEED:

“The preferred waste management strategies described by the U.S. Environmental Protection Agency (EPA) are source reduction, reuse, recycling and recovery.”

" Reduce " or " source reduction " is the top strategy for avoiding waste altogether.

The LEED rating system is designed to address the most important environmental impacts and human benefits of green building. The impact categories are based on the U.S. Environmental Protection Agency’s TRACI method (Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts), which evaluates the potential environmental effects of a product or process over its life cycle. The impact categories are: reverse contribution to global climate change; enhance individual human health and well-being; protect and restore water resources; protect, enhance and restore biodiversity and ecosystem services; promote sustainable and regenerative material cycles; build a greener economy; enhance social equity, environmental justice, community health and quality of life. Among these categories, reducing contribution to climate change and enhancing human health and well-being have been identified as the most important ones for a LEED project to accomplish. References: LEED v4 Green Associate Candidate Handbook, LEED v4 BD+C Reference Guide

The statement that is the U.S. Green Building Council (USGBC) vision is: Buildings and communities will regenerate and sustain the health and vitality of all life within a generation. USGBC is a non-profit organization that promotes sustainability in the building industry through its LEED rating system, education programs, advocacy initiatives, and research projects. USGBC’s vision reflects its commitment to transformingthe built environment into one that supports human health, environmental quality, social equity, and economic prosperity1 . References: LEED v4 Green Associate Candidate Handbook1, USGBC’s Vision

Implementing a green roof to manage rainwater is the best answer because it directly supports Sustainable Sites strategies. A vegetated roof can reduce runoff volume, slow peak discharge, improve rainwater quality, reduce heat island effects, provide habitat benefits, and create usable or visual open space depending on design. Optimizing energy performance is important, but it belongs mainly to Energy and Atmosphere. Rapidly renewable or responsibly sourced materials relate to Materials and Resources. High-efficiency plumbing fixtures belong to Water Efficiency. Since the question asks specifically how to maximize points in the Sustainable Sites category, the project team should prioritize site-based strategies such as rainwater management, heat island reduction, site assessment, open space, and habitat protection. A green roof is the option most aligned with SS goals.

Installing greywater treatment systems for landscaping is the correct answer because greywater can be reused as a non-potable water source for appropriate applications such as irrigation, where allowed by code. LEED Water Efficiency encourages reducing potable water use through demand reduction, efficient irrigation, climate-appropriate planting, and alternative water sources. Spray irrigation at midday is inefficient because evaporation losses are higher during hot, sunny periods. Groundwater may be non-potable in some cases, but using it can deplete aquifers and does not represent the preferred conservation strategy. Increasing potable water use is directly contrary to LEED water reduction goals. Greywater reuse can reduce demand on municipal potable water supplies while supporting landscape health when properly treated, permitted, and managed.
