One of the things that LEED promotes by encouraging compact development is walkability. Compact development is a form of urban planning that aims to reduce sprawl and make more efficient use of land and resources by increasing density, diversity, and connectivity of land uses5. Compact development can enhance walkability by creating mixed-use neighborhoods that provide a variety of destinations within walking distance, such as shops, services, workplaces, schools, parks, and transit stops. Walkability can offer multiple benefits for the environment, health, economy, and social equity. For example, walkability can reduce greenhouse gas emissions and air pollution by replacing car trips with walking or transit; improve physical and mental health by increasing physical activity and reducing stress; support local businesses and generate tax revenues by increasing foot traffic and property values; and foster social cohesion and civic engagement by creating vibrant public spaces and enhancing accessibility for all6.

Explanation
Unless mitigated, resource consumption over the life of a conventional building incrementally increases the total emissions footprint. This is because conventional buildings often use non-renewable resources for energy and materials, which contribute to greenhouse gas emissions during extraction, production, use, and disposal.

Open-grid paving is a permeable hardscape strategy that allows rainwater to infiltrate through the surface rather than running off quickly into storm drains. In LEED Sustainable Sites, rainwater management aims to maintain or restore natural hydrology, reduce runoff volume, improve water quality, and limit downstream erosion and sedimentation. Option A is incorrect because alternative transportation is supported by strategies such as bicycle facilities, access to transit, reduced parking footprint, and green vehicles. Option B is incorrect because light pollution is addressed through exterior lighting design and fixture control. Option C is not the best answer because paving a parking area does not preserve native habitat, although it may reduce runoff impacts compared with conventional asphalt.

Integrative design is the term that encourages team members to collaborate throughout the process of design and construction to create synergistic solutions. Integrative design is an approach that considers the interrelationships among various building systems, environmental factors, and occupant needs, and seeks to optimize the performance, cost, and environmental benefits of the project. The LEED Green Associate Candidate Handbook states that one of the intents of the Integrative Process category is to "support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems" [1, p. 12].

Explanation
Rainwater Management is a credit that aims to reduce runoff, improve water quality, and restore natural hydrology1. It is part of the Sustainable Sites category, which addresses the environmental impacts of the site selection, design, and construction23.
