ASHRAE 62.1 is the standard for ventilation and acceptable indoor air quality in commercial and institutional buildings. It specifies the minimum ventilation rates and other measures to provide good indoor air quality for occupants. LEED v4 references ASHRAE 62.1 as a prerequisite for the Indoor Environmental Quality credit category.

ASHRAE 62.1 from the LEED v4 Green Associate Candidate Handbook, page 18.

Enhance Indoor Environmental Quality (IEQ) from the WBDG website, section on Adequate Ventilation and Exhaust.

Paved surfaces absorb and retain heat, increasing local temperatures and contributing to the heat island effect. LEED encourages mitigating this effect by using materials with high Solar Reflectance Index (SRI) or implementing strategies like green roofs and shaded areas​​.

Rainwater is considered an alternative water source because it is a sustainable source of water that is not supplied from fresh surface water or groundwater. Rainwater can be harvested from roofs or other surfaces and stored for later use. Rainwater can offset the demand for freshwater and reduce the pressure on water resources. Rainwater can be used for various purposes, such as irrigation, toilet flushing, cooling, and cleaning. LEED projects can earn credits for using alternative water sources under the Water Efficiency category. References: Best Management Practice #14: Alternative Water Sources1; LEED v4 BD+C Reference Guide, Water Efficiency, page 51

An integrative process is a collaborative approach that involves all project stakeholders in the design and decision-making process from the beginning to the end of a project. It aims to optimize the performance, environmental, social, and economic outcomes of a project by considering the interrelationships and synergies between various building and site systems. By identifying overlapping relationships, services and redundancies among systems, an integrative process can result in increased performance and reduced costs, as it can create more efficient, effective, and innovative solutions that meet the project goals and requirements. For example, an integrative process can help to reduce the energy demand of a building by integrating passive design strategies, such as building orientation, envelope design, daylighting, natural ventilation, and shading, which can also improve the indoor environmental quality and occupant comfort. An integrative process can also help to reduce the material and water consumption of a project by reusing existing resources, selecting durable and low-impact materials, and implementing water-efficient fixtures and systems, which can also reduce the waste generation and environmental impact of the project
