Prerequisites and credits are the two types of requirements that make up the LEED rating system. Prerequisites are the basic elements or strategies that must be included in any LEED certified project, regardless of the rating system or the level of certification1. Credits are the additional elements or strategies that can be included in a LEED project to achieve higher levels of performance and certification1. Credits are optional and have different point values depending on their environmental benefits and impacts2. Therefore, the correct answer is B. Prerequisites are mandatory and credits are optional.

Daylighting is a strategy that uses natural light to illuminate the interior spaces of a building, reducing the need for artificial lighting and improving the visual comfort and well-being of the occupants. One of the strategies that can help improve daylighting in an office building is tolocate private offices toward the building core and organize cubicles at the perimeter, so that more people can benefit from the access to windows and views. This can also increase the daylight penetration depth and reduce glare and contrast12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

Infill development refers to building within unused and underutilized lands in existing urban areas, rather than developing on greenfields or open land. According to LEED v4 BD+C under LT Credit: Sensitive Land Protection and LT Credit: High Priority Site, infill development:

"Encourages development in locations with existing infrastructure to reduce environmental impacts of new construction."

"Limits land consumption and supports compact development by building on previously developed sites in established communities."

This practice supports smart growth, reduces the need for new roads and utilities, and maximizes land efficiency.

Option B (Parking restrictions) help reduce car use but don’t directly address land efficiency.

Option C (Financial incentives) are policies, not land-use strategies.

Option D (Increased open space) preserves land but doesn't reduce development footprint unless combined with compact development.

Correct answer: A. Infill development — it most directly supports land efficiency and sustainable site development.

vocs are volatile organic compounds that can evaporate from paints, solvents, adhesives, and other building materials. They can cause health problems such as eye irritation, respiratory distress, headaches, and cancer. Limiting the concentration of vocs in the air protects the health of construction personnel by reducing their exposure to these harmful substances12.
